SentriLock Power Paddle
If your lockbox becomes completely unresponsive, the lockbox may require a Power Paddle, which can be leased or purchased from any GCAAR location. In the event that your lockbox becomes unresponsive, make sure that you contact SentriLock first, to confirm that the batteries need to be replaced and the lockbox requires a Power Paddle. For more information regarding the process, please contact GCAAR at (301) 590-2000.
Save the Battery - Close The Lockbox After a Showing
GCAAR would like to remind agents, when showing property, please close the lockbox once you've extracted the keys. If the lockbox is left open while showing the property, the lockbox continues to drain the batteries. Upon leaving the property, open the lockbox, again, with your SentriLock card and place the keys in the container. Close the lockbox door. Lockbox batteries last approximately 2-3 years with normal use.
