Portable key safe for outdoor access

It is built for homeowners, property managers or tradespeople who need to grant temporary entry without handing out physical keys. The grey finish and weather-resistant construction suit exterior mounting on a door handle, fence or wall bracket.

Simple shackle mounting with anti-jam hook

Installation takes seconds: slide the integrated shackle over a door knob, gate latch or pipe and snap it shut — no tools or drilling required. The included anti-jam key hook keeps the key ring from catching on the lid, which is the most common cause of a stuck mechanism. If the buttons feel stiff, wipe away grit and apply a light dry lubricant; forcing the code dials can damage the internal tumblers.

Five-key capacity decides suitability

The single specification that determines fit is the internal capacity of five standard keys. Larger key rings, bulky fobs or multiple access cards will not fit, so buyers needing to store more than five items should look for a larger vault.
