And you can change the code as often as you wish. This model is the one used most often on military ships and subs.

Every CYPHER® LOCK system includes a push-button panel and a logic controller that will activate the included heavy duty Sargent & Greenlief Brute Lock. Plus it offers electronic safety and back-up features that make it far more intelligent than a conventional lock and key. Comes with it's own power supply that is also used to power the included lock. • Adjustable "door open" time.

• Hostage alarm for entry under duress.

• Error alarm to expose guessers.

• Burglar alarm interface.
