The Oxford Boss Alarm has been independently tested and approved by Sold Secure (Gold Standard), SBSC, Classe SRA, and FG.

As well as being an extremely secure lock, it comes with an ear-splittingly loud 100 dB alarm which is triggered by movement sensors; you can also lock it up without setting the alarm.

A key replacement service is available so that if you are unfortunate enough to lose all your keys, a new one can be made up. Just remember to take note of your key number and keep this in a safe place.
