The Ultimate Buying Guide for Key Lock Boxes
A key lock box is a handy tool. It lets you safely store extra keys outside your home or business. This guide helps you pick the best one for your needs.
Key Features to Look For
Security and Access
- Locking Mechanism: This is the most important part. Combination locks are common. You set your own secret numbers. Push-button or rotary dials work well. Some high-end boxes use electronic keypads. These often allow for temporary codes for guests.
- Shackle or Mounting: How will you attach the box? Some boxes have a strong shackle (like a thick metal loop). You use this to hang the box on a doorknob or railing. Other boxes mount directly to a wall using screws. Wall-mounted boxes offer better security against quick removal.
- Capacity: How many keys do you need to store? Smaller boxes hold just one or two spare keys. Larger boxes can hold car fobs or multiple house keys. Check the internal dimensions before buying.
Durability and Weather Resistance
- Weatherproofing: Since these boxes live outside, they must handle rain and sun. Look for tight seals around the door and keyhole. A good box resists water intrusion.
- Tamper Resistance: The best boxes resist prying. Check for thick metal construction. If the box is easy to smash open, it won’t keep keys safe.
Important Materials
The material directly affects how long your box lasts and how secure it is.
- Zinc Alloy: Many standard boxes use zinc alloy. It is strong enough for basic use. It resists rust well.
- Stainless Steel: This material offers superior strength. Stainless steel lasts longer, especially in harsh, salty, or very wet environments. It costs more, but it is worth the investment for high-security needs.
- Brass (for Locks): The internal components of the lock cylinder are often made of brass. This metal resists corrosion, keeping the mechanism moving smoothly over time.
Factors That Improve or Reduce Quality
Quality Boosters
- Thick Metal Casing: Thicker metal means a burglar needs more time and tools to break in. This is a huge quality indicator.
- Protective Cover: High-quality boxes often feature a sliding cover or door that hides the combination dials. This protects the numbers from weather and people guessing them.
- Easy Reset Mechanism: If you use a combination lock, the ability to easily reset the code yourself improves the user experience significantly.
Quality Reducers
- Thin Plastic Components: If the shackle cover or internal trays are made of cheap plastic, they will break quickly when exposed to the elements.
- Exposed Dials: Dials left open to the rain will quickly become stiff and hard to turn. Water damages the internal lock parts.
- Weak Mounting Points: If the mounting holes are too small or the metal around them is thin, a determined thief can easily rip the box off the wall.
User Experience and Use Cases
Think about who needs access and how often.
- Real Estate Agents: They need quick, temporary access for showings. Boxes with temporary code features are perfect for this use case.
- Homeowners Needing Emergency Access: If you lock yourself out, you need a box that is easy for a trusted family member to open quickly. Simplicity in dialing is key here.
- Rental Property Managers: Managers often need to give keys to cleaners or repair workers. Programmable codes that can be changed after each visit offer the best control.
A good key box should feel solid when you handle it. The combination dials should turn crisply, not loosely. Test the mechanism before you install it permanently.
10 Frequently Asked Questions (FAQ)
Q: What is the main benefit of using a key lock box?
A: The main benefit is safe, temporary access for trusted people without hiding a key under a rock or mat, which is very easy for thieves to find.
Q: Are key lock boxes truly secure?
A: They are secure against casual searching. However, very determined burglars with tools can eventually break into any lock box. Choose heavy-duty metal ones for better protection.
Q: How often should I change the combination?
A: If you share the code with many people, you should change it often. If only one trusted person knows it, changing it once a year is usually enough.
Q: Can I mount a key box anywhere?
A: You should mount it somewhere discreet but accessible. Avoid placing it right next to the front door where it is easily seen.
Q: What does “weatherproof” mean for a lock box?
A: It means the box resists rain and sun damage. It usually has tight seals to stop water from getting inside the locking mechanism.
Q: What if I forget my combination?
A: If you have a standard combination lock, you might have to use a strong tool to try and force the lock open, or cut the box open. Electronic boxes sometimes have a backup key system.
Q: Should I buy a shackle box or a wall-mount box?
A: Wall-mount boxes are generally more secure because they are bolted down. Shackle boxes are easier to move or steal entirely.
Q: What size key box do I need?
A: Measure the largest item you plan to store. If it is just one house key, a small box works. If you need to store a car fob, you need a much deeper box.
Q: Do key boxes work in very cold weather?
A: Extreme cold can sometimes make mechanical locks sticky. Make sure the box uses quality lubricants and avoid boxes with too many cheap plastic parts.
Q: What is the best way to install a wall-mount box?
A: Always use the long, heavy-duty screws provided by the manufacturer. Screw them into solid wood studs or masonry, not just the siding or thin trim.
