Key Lock Boxes
Key lock boxes (key safes) solve a simple problem: someone needs to get in, but you are not there to hand over a key. A weather-resistant box mounted beside the door — or hung on a gate — holds a spare key behind a 4-digit code you share with family, cleaners, tradies or short-stay guests. They are not smart locks and they do not replace a proper deadbolt; they are controlled spare-key storage for when copying keys or being home is impractical.

Key Lock Boxes — questions
What is a key lock box used for?
It stores a spare key securely outside your home. You share the combination with people who need access — family, cleaners, tradies, Airbnb or Stayz guests — without hiding keys under a mat or leaving the door unlocked.
Are key lock boxes safe?
They are safer than leaving a key in the open, but security depends on placement, a strong unique code and a quality box. Mount discreetly, change the default code, and treat the combination like a password. They deter opportunistic access; determined thieves may still attack a visible box.
Wall mount or portable — which is better?
Wall-mounted boxes are harder to remove and suit owner-occupiers. Portable shackled boxes need no drilling — ideal for renters, gates, beach houses and temporary tradie access. Many Gold Coast hosts use both: wall mount at the main entry and portable on a pool or side gate.
Can renters use a key lock box?
Yes — portable hangable models are popular with renters because they leave no permanent fixings. Check your lease; some landlords prefer you do not drill walls. A shackle box on a door knob or railing is usually the easiest approved option.
Do key lock boxes work for Airbnb and Stayz?
They are one of the most common short-stay solutions in Australia. Set a unique code per booking or rotate a single code between guests, and place the box where check-in instructions are easy to follow. For higher turnover, a smart lock with app codes may be less hassle than physical key swaps.
Will a car key fob fit inside?
Standard house keys fit most boxes. Bulky smart fobs and multi-key bunches need a larger interior — check dimensions before buying. Master Lock portable models are known for tight capacity with some fobs.
How is this different from a smart lock?
A lock box holds a physical spare key. A smart lock replaces your door hardware with keypad, fingerprint or app entry. Many households use a lock box as backup even after installing a smart lock, or on secondary doors and gates smart locks cannot reach.
Spare keys without hiding under the mat
Wall-mounted or portable — share a code with guests, tradies and family while you are away. Mount discreetly and change the factory combination.
