IMPORTANT:
SentriLock Generation 3 lockboxes require an adapter for battery replacement when the current batteries are too low to power the door open to replace the batteries inside. Battery Adapters are NOT needed for SentriGuard Generation 4 lockboxes.
We are unable to provide a free battery adaptor kit, even if your SentriLock lockbox is under warranty. If you need to purchase a battery adaptor kit, please contact our Tenant Turner Support Team.
We highly recommend purchasing a battery adapter or two to have on hand in case your SentriLock Generation 3 lockbox stops working due to low batteries.
Each SentriLock lockbox battery adapter costs $20.
Battery adapters are required for SentriLock Generation 3 lockbox troubleshooting when requesting a warranty replacement.
How to replace the batteries using the battery adapter:
Insert two new batteries into the external battery adapter.
Insert the external battery adapter into the battery port on the side of the lockbox (behind the rubber plug).
