Upgrade your property with a security system that works for you. AA Sentinel Locks provides digital entry solutions that remove the frustration of physical keys while giving you full control over your premises.
This service is built for those who need to manage entry for staff, support workers, or tenants without the constant need for manual coordination.
Why Choose AA Sentinel Locks?
Handling access should be easy. Our systems are designed for retail spaces, NDIS properties, and rental managers who value their time.
Send codes to cleaners or trades instead of driving across town to drop off a key.
These units run on battery power. That means no messy wiring and no need for an electrician.
Access via keypad, swipe card, or fingerprint.
Every lock features a secure deadlocking system and a physical key override as a secondary option.
