The comparison below highlights the differences in key capacity, installation style, weather protection, and access features across all ten key lock boxes, making it easier to match a box to routine showing schedules or broader property-management needs.
The Master Lock Portable 5400EC combines a practical five-key capacity with a straightforward hanging design, earning a 4.7 rating among customers. It is a natural fit for agents who need a dependable place to leave a property key during a showing, whether that listing is vacant, occupied, or managed remotely.

Its strongest qualities are the resettable four-digit combination, compact metal construction, and vinyl-coated shackle. The shutter helps shield the combination dials from rain, dust, and everyday exposure, while the coated shackle reduces the chance of marking a painted door knob or nearby finish during installation.
The tradeoff is capacity. The 5400EC is designed for up to five standard house keys, so it works best for a single listing or a small group of related keys. It is not the appropriate choice for a property manager carrying a dense key ring, multiple electronic fobs, or a large collection of access cards.
This is a strong general-purpose selection for individual realtors, assistants, and showing agents. It combines portability with dependable outdoor-oriented protection and avoids unnecessary complexity, making it one of the most balanced choices in the guide.
The resettable combination allows the code to be changed whenever access needs to move to another person. A realtor can create a dedicated showing code, share it according to the listing's procedures, and change it later without replacing a physical lock or tracking copied keys.
The vinyl-coated shackle provides a softer contact point than bare metal. It is particularly useful when the box hangs temporarily from a knob or other visible fixture where scratches would be conspicuous to an owner, tenant, or home inspector.

The Master Lock 5401D is a fixed-installation alternative to the portable 5400EC, and its 4.7 rating reflects a simple, proven format. It holds up to five keys and is intended for installation on a wall or another fixed object, making it well suited to a permanent agent office or a property with a secure exterior entry point.

The metal body supports regular use, while the shutter door protects the combination dials from weather when the box is installed outdoors. Its four-digit code can be reset to a personalized combination, and the stated dimensions keep the enclosure compact enough for locations where a large safe would be impractical.
Unlike a portable model, this unit cannot easily move from property to property. Realtors must plan mounting hardware and select a location that will not interfere with the property, landscaping, maintenance work, or the movement of residents. The stated internal volume also limits it to standard keys rather than bulky fobs.
It is a good choice for a real estate office, recurring rental workflow, or one property with a trusted access point. Compared with a hanging box, it presents a cleaner and more permanent solution, provided the installer can identify a sound mounting surface.
Wall or fixed-object mounting makes the 5401D suitable for workflows where the same lockbox remains in service. This reduces the need to carry a portable unit to every showing and gives contractors, cleaners, or assistants a consistent place to retrieve authorized keys.
The mechanical combination avoids batteries, charging, and app connectivity. For a realtor who values predictable operation in vacant homes or rental properties, that simplicity can be more useful than features associated with connected access systems.

The Puroma Large Gray offers unusual installation flexibility because its removable shackle supports both wall-mounted and hanging placement. It has a 4.6 rating and is positioned for realtors, cleaners, pet sitters, and others who need controlled access to a home, apartment, rental, or warehouse.

Inside, the box provides ample space for house keys, while the resettable four-digit mechanism offers 10,000 possible codes. Its aluminum alloy and reinforced steel construction is intended to resist hammering and sawing, and the protective door helps limit exposure to dust and rain during normal use.
The stated information does not provide an exact key capacity, so buyers who require a guaranteed number of standard keys should verify the interior dimensions before ordering. The product also includes installation options rather than forcing every user into a permanent wall setup, though proper fasteners and a sound surface are still important.
This model is a strong fit for a realtor who wants one box to serve different properties or changing access arrangements. Its versatility makes it more adaptable than a strictly portable or strictly fixed unit, while the metal shell and weather protection support use around rental entrances.
Removing the shackle allows the enclosure to be mounted on a wall, while retaining it allows temporary placement on a suitable handle. That flexibility helps an agent adapt to properties with different fixtures and to working habits that change from one showing to the next.
The roomy interior can hold more than a single loose key, making the box practical for a small collection of related keys. A code that can be changed repeatedly also supports controlled handoffs to cleaners, maintenance personnel, or short-term occupants.

The Master Lock Push Button 5422EC stands apart with its touch-based, alpha-and-numeric control system, and it carries a 4.4 rating. It stores up to five keys and is designed for both indoor and outdoor use, making it an option for realtors who prefer a different code-entry experience from standard rotating dials.

The weather cover protects the push buttons, while the metal body and vinyl-coated shackle support durability and reduce surface scratching. The unit includes detailed dimensions for the body, interior, and shackle, which is useful when a realtor needs to confirm that a knob, gate, fence, or narrow mounting area will accommodate it.
Its largest drawback is bulk. At 6.84 inches tall, the 5422EC is longer than many portable alternatives, and the push-button interface may require more deliberate use than a simple numeric dial. The manufacturer also recommends checking door measurements and knob styles before installation.
It suits agents who want a more distinctive access code or need alphanumeric characters as part of a temporary password. For standard key-drop workflows, it remains functional, but the 5400EC offers a more compact profile and a more familiar mechanical combination format.
The alpha-and-numeric control gives users a wider range of possible password patterns than a standard four-digit wheel. That can be useful when the agent prefers longer or less predictable temporary access strings for different people.
Published shackle, exterior, and interior dimensions make advance planning easier. Realtors can compare the reach of the hanging loop and the clearance required by the control cover before arriving at a property.

The Puroma Peacock Blue combines a portable format with optional wall mounting, making it an economical choice for independent agents and small rental portfolios. It has a 4.6 rating, and its four-digit resettable code provides 10,000 possible combinations without requiring a key to operate the lock.

The enclosure is made from aluminum alloy and steel, with listed resistance to rust, corrosion, hammering, sawing, and prying. Four screws and four expansion plugs are included for permanent placement, while the removable shackle allows the box to hang from a handle or other suitable point when mobility matters.
The exact key capacity is not specified, so a user should not assume it will accommodate a crowded ring or several electronic fobs. Its exterior color may also be less discreet than black or neutral finishes in certain neighborhoods, although the distinct appearance can make a legitimate lockbox easier for service providers to identify.
This is a practical pick for a realtor who wants a straightforward mechanical lockbox with both installation choices. It works well for temporary showing access, cleaners, pet sitters, and short-term rental operators, especially when flexible placement is more important than a polished finish or guaranteed high capacity.
The removable shackle creates an easy choice between temporary hanging placement and a more permanent wall mount. Agents can use the same box across different properties, while rental owners can select a fixed installation when consistent access is needed.
The supplied instructions describe a simple four-step reset process, and the dials begin at 0-0-0-0. Users should set a custom code before the box enters service, then test the new combination multiple times with the door open.

The Kingsley Guard-a-Key is explicitly designed with realtors and vacation-rental operators in mind. Its 4.6 rating reflects a secure-looking, portable design that stores multiple keys and uses a resettable four-digit code, all while maintaining a relatively discreet black appearance.

Solid metal construction and a weather-resistant finish are intended to protect the box from rust, corrosion, and exposure to the elements. The shackle has a vinyl covering to reduce scratching, which is a considerate detail for agents placing the box on a finished door or painted fixture.
The product information does not specify an exact number of keys or include wall-mounting hardware, so it is less clearly suited to high-volume access management. As with any hanging lockbox, the security of the installation also depends on the strength of the attachment point and whether the property's procedures permit outdoor key storage.
This model is a good choice for a traditional realtor, vacation-rental host, or dog walker who values a familiar portable design and understated appearance. It supports shared access for maintenance and cleaning teams while keeping the unit simpler than a high-capacity, fixed wall-mounted system.
The listing applications directly include real estate agents, property managers, vacation rentals, dog walkers, homeowners, and service teams. That focus makes the Guard-a-Key a natural choice for shared access that does not require a complex connected system.
The black finish is designed to blend into many surroundings, while the coated shackle helps avoid visible marks. These details can be useful at occupied properties where the temporary lockbox must be less obtrusive than a large storage container.

The Master Lock Wall Mount 5423EC combines the push-button access style of the 5422EC with a permanent installation format. It carries a 4.4 rating, stores up to five keys, and is intended for realtors or property managers who prefer to establish a consistent access point for service personnel.

Mounting hardware is included, so the box can be fixed to a suitable wall or object without requiring a separate purchase of basic fasteners. Its metal body and weather cover protect the control area, while the alpha-and-numeric code can be reset to create a personalized access string.
A fixed location reduces flexibility. The unit cannot be moved easily between properties, and the realtor must consider the owner's permission, placement visibility, wall material, and long-term maintenance. Capacity is also limited to five standard keys, which may be inadequate for a team operating many doors at once.
This box works best for a dedicated rental, managed property, or agent office with a reliable mounting surface. Its appeal lies in combining a more permanent structure with a convenient push-button code and weather protection rather than offering the storage volume of a large property-management cabinet.
A permanent box gives cleaners, maintenance crews, and showing agents a predictable location. The resettable code allows the manager to change access without replacing keys when a person or tenant changes.
The cover over the buttons helps keep rain and debris away from the controls. The metal housing and included mounting hardware support a straightforward fixed installation in a suitable location.

The Puroma Gray Combination is a durable, flexible choice for real estate access, rated 4.6 by customers. Its detachable shackle permits either door or wall installation, while the four-digit code offers 10,000 combinations and a reset mechanism for personalizing access.

The aluminum alloy shell is designed to resist hammering, sawing, and prying, and the box is described as rustproof and corrosion-resistant. Those characteristics suit outdoor placement around apartments, garages, rental houses, and warehouses where the enclosure may encounter changing weather.
As with other Puroma models in this guide, the supplied information does not state an exact number of keys. The shackle is located inside the box, so it must be opened before removal; this is not a problem, but it is a practical installation detail worth understanding. Wall placement also requires suitable fasteners and permission from the property owner.
The Gray Combination is best for a realtor who values a neutral appearance, durable shell, and flexible installation without needing a large key-capacity cabinet. It can support showing agents, cleaners, pet sitters, and short-term rental access with a regularly changed code.
With the shackle installed, the box can be carried between properties or hung temporarily. Removing it turns the enclosure into a fixed wall unit, giving the user more control over long-term placement.
The reset mechanism allows a code to be personalized whenever access needs to change. Realtors can avoid distributing copies of a physical key and update access for a new tenant, contractor, or showing agent.

The Iron Lock XXL is the clear high-capacity selection in this guide, with room for approximately 20 to 30 house keys, car fobs, and access cards. Its 4.6 rating makes it attractive to property managers, agents handling several properties, and teams that need one organized location rather than several small key boxes.

A built-in tray keeps keys from tumbling out when the door opens, while two included hooks create additional hanging points. The package includes four screws and four wall anchors, and a sliding shield protects the dials from rain, dust, and grit. A rust- and corrosion-resistant metal body supports year-round outdoor use.
Its capacity comes with a larger fixed installation requirement, and the stated interior measurements should be checked against the number and bulk of the keys to be stored. The manufacturer also explicitly notes that it is not a sealed waterproof case, so an eave, porch, or other overhang is preferable where practical.
This is the best option for a busy property manager or rental team that needs a centralized, organized key station. It is less appropriate for an occasional agent wanting to carry one small box to a single showing, but it offers the strongest combination of capacity and internal organization in the list.
A 20-to-30-key capacity allows related keys, fobs, and access cards to remain together. The organizing tray and hooks reduce clutter and make individual items easier to identify when multiple people need access.
The body and dial shield are built to tolerate outdoor exposure, but the unit is not sealed. Installing it beneath an eave or overhang adds another layer of protection and can prolong smooth dial operation.

The Rudy Run Large Lockbox is a strong outdoor-oriented choice for realtors and short-term rental hosts, carrying a 4.7 rating. It can store at least five house keys as well as small items such as key fobs, access tags, credit cards, or USB devices, giving it more flexibility than a box limited to loose house keys.

Its zinc alloy and stainless steel construction is intended to resist rust, corrosion, and outdoor exposure. A personalized four-digit code provides more than 10,000 combinations, allowing access to be updated for different guests, cleaners, agents, or property managers without changing the lock itself.
The wall-mounted design requires permanent installation, so the box is better for recurring rental operations than for agents who need a portable unit. Buyers must also account for local permission, mounting-surface quality, and the possibility that exposed outdoor placement will collect dirt or moisture despite the protective materials.
It is a good fit for an Airbnb host, property manager, or realtor with a stable access location. The ability to hold both keys and small essentials sets it apart, while included screws and nylon expansion plugs make setup more convenient for a suitable hard surface.
The compartment can accommodate at least five house keys along with compact access items. This makes the box useful for short-term rental operations where a guest or service provider may need a key, fob, or access tag from the same secure location.
Included screws and nylon expansion plugs support installation on hard surfaces. Once secured, the box offers a consistent location that can be shared through a resettable code rather than through multiple physical key copies.

The most useful key lock box for realtors is the one that fits the access pattern, key load, and installation environment of the property. Capacity, mounting style, weather protection, code control, and local security rules should be considered together rather than in isolation.
Start by counting the keys the box must hold and noting whether they are standard house keys, crowded key rings, electronic fobs, or access cards. A five-key hanging box is usually sufficient for one showing, while a 20-to-30-key cabinet is more appropriate for property teams managing several doors. Published interior dimensions are important because nominal key counts do not always account for bulky accessories.
Choose enough space for current operations without turning the lockbox into an unsecured storage bin. A tightly packed compartment can make keys difficult to remove and may encourage owners to hide additional keys elsewhere.
A portable box is convenient when the same unit moves among vacant properties, rental homes, or scheduled showings. It should hang securely from a suitable point and include a coated shackle to reduce scratches. A wall-mounted model is better for a fixed access location because it is less exposed to accidental removal and can serve contractors or cleaners consistently.
Match the mounting style to the workflow rather than choosing only by appearance. Agents who travel between properties will usually value portability, while property managers may prefer a permanent installation.
Look for a metal body, protected controls, and a cover or shutter over the combination mechanism. Even weather-resistant products benefit from placement under an eave, porch, or overhang. Products described as waterproof should be assessed for their stated limits, since some outdoor lockboxes resist rain without being completely sealed against moisture and dust.
For long-term outdoor service, corrosion resistance matters nearly as much as resistance to rain. Periodic inspection can reveal blocked dials, standing water, or a loosening attachment before access is affected.
Most models offer a four-digit code with 10,000 possible combinations, while some use a longer alphanumeric string. More combinations are helpful for shared access, but the most important feature is the ability to change the code after personnel, tenants, or guests change. Avoid predictable codes and avoid reusing a code after a showing.
A resettable lock lets the realtor control access without replacing the enclosure. It also means that the code itself must be recorded securely, because a forgotten combination can create a service problem.
Metal housings, including steel and aluminum alloy, are generally more appropriate for realtor use than lightweight plastic containers. A protective shutter can add another obstacle to tampering while keeping dials readable. No portable lockbox substitutes for a secure property, so placement, visibility, and local authorization remain critical.
Look for a rigid body and a locking mechanism that operates smoothly. The box should protect keys from casual interference and opportunistic tampering without being marketed as a certified high-security safe.
Wall-mounted products should ideally include screws, anchors, or expansion plugs suited to common surfaces. A complete mounting set reduces setup friction, although the agent still needs permission to install anything on a property. Check the wall material and choose a location where the box will not interfere with residents, landscaping, vehicles, or maintenance.
Include the required tools and hardware in the vehicle if installation locations vary. Portable alternatives offer a useful fallback when a permanent mounting surface is unavailable or prohibited.
Color, shape, and size influence how noticeable the lockbox is. Black or gray finishes often blend into doors, fences, and utility areas, while a bright color may make the box easier for legitimate service providers to identify. At occupied properties, discretion and a scratch-free installation are often as important as security.
Choose a finish that looks appropriate for the neighborhood and the owner's standards. A visible box is not necessarily a poor choice when consistent identification benefits cleaners, agents, and emergency personnel.
Before installing any outside key box, check the listing agreement, brokerage policy, lease, landlord instructions, and local regulations. Some communities or homeowners associations restrict lockboxes or particular installation methods. The realtor should also follow any showing instructions supplied by the seller or listing agent.
Use the lockbox only for authorized access and remove keys and codes as soon as the service period ends. Good operating procedures are as important as the hardware itself.
Before putting keys into a new lockbox, set a private code while the door is open, then close and reopen it to confirm the combination works. Test the code several times and record it in a secure place. Do not leave the box at its factory setting, and avoid codes that can be guessed from a listing address, date, or agent name.
Install the box only with the property owner's or listing agent's permission. Check the attachment point, surface compatibility, and clearance around the door or knob. If wall mounting, use suitable anchors and confirm that the enclosure is firmly attached. Keep the keys organized, remove the relevant key ring when a showing or service visit ends, and change the code whenever access is no longer needed.
Clean the combination dials and door regularly with a soft, dry cloth, and check the shackle, fasteners, and weather cover for looseness. Keep the interior dry and remove obsolete keys. If the unit is exposed to severe weather, inspect it frequently and consider moving it beneath an overhang. At the end of a listing or rental cycle, retrieve the keys, reset or disable the code, and remove the box if the installation was temporary.
A single showing or small property usually needs a box that holds up to five standard house keys. A property manager may need 20 to 30 keys, plus room for fobs and access cards, which calls for a larger cabinet such as the Iron Lock XXL. Choose a capacity that fits the current workload without making the box difficult to organize.
A quality lockbox with a metal body, protected controls, and a secure attachment point can be suitable for outdoor access. It should still be placed under an eave or overhang when possible, and it should never be treated as a substitute for a secure deadbolt or a complete alarm system. Local rules and listing instructions also govern outdoor key storage.
Changing the code after each person finishes using it is a strong access-control practice, especially when the same property receives multiple service providers. It prevents a previous visitor from retaining working access. Record the current code securely and confirm that the new combination operates correctly before leaving the property.
A portable model can be carried among properties when the installation point and local rules permit it. A wall-mounted unit is generally better for a single fixed access location because it is easier for agents and service providers to find. The 5423EC and 5401D are designed for wall or fixed-object installation, while several Puroma and Master Lock portable models can be moved.
A portable lockbox hangs from a knob, gate, fence, or other attachment point and is convenient for mobile showings. A wall-mounted lockbox is fixed to a surface and is better for consistent access by cleaners, contractors, or property managers. Wall mounting usually looks more permanent and may require appropriate hardware, permission, and a suitable surface.
A four-digit mechanical lock provides useful deterrence and controlled access for ordinary property-service workflows, particularly when the box has a solid body and protected mechanism. Its effectiveness still depends on the code, installation point, visibility, and whether unauthorized people know where to look. A longer alphanumeric code can add more possible combinations.
Store the code in a secure password manager or another protected location rather than on a note attached to the property. Share it only with authorized individuals through an appropriate method, avoid using information associated with the listing, and change it promptly when a person no longer needs access. Access records should follow brokerage and company procedures.
It depends on the interior dimensions and the size of the accessories. The larger Iron Lock XXL and Rudy Run boxes are specifically described as suitable for fobs, tags, or other compact items, while compact five-key models are better reserved for standard house keys. Check the published interior measurements before placing electronics inside.
The Master Lock Portable 5400EC is the most balanced overall choice for individual agents because it combines five-key capacity, a resettable code, a portable shackle, and weather protection. The Puroma Peacock Blue stands out as the value pick with two installation options, while the Iron Lock XXL offers the strongest capacity and organization for busy property teams.
Prioritize the access workflow before the features. Choose a portable unit for showings that move from property to property, a fixed wall box for a recurring rental or service-access point, and a larger cabinet when multiple keys and fobs need organized storage. Installation permission, code management, weather exposure, and exact interior dimensions matter just as much as the lock itself.
Product configurations, availability, and prices can change, so check the current listing and the manufacturer's instructions before buying. Set a custom code, test it repeatedly, use suitable mounting hardware, and remove or reset access as soon as the listing or service period concludes.
