SentriLock lockboxes require an adaptor for battery replacement when the current batteries are too low to power the door to open to replace the batteries inside. You are able to purchase a battery adaptor separately to have on hand in case your SentriLock lockbox stops working due to low batteries.

Each SentriLock lockbox battery adaptor costs $20 and is available to purchase through the "buy" link found under the SentriLock icon on the billing page of your account. Note: Only Administrative users will have access to the billing page.

Battery adaptor kits include everything you need:

  • External battery adapter

  • 4 lithium-ion batteries (each lockbox requires 2 batteries)

  • Multi-tool to open battery compartment

  • Instruction booklet
