If your lockbox becomes unresponsive, the lockbox may require a Power Paddle, which can be leased or purchased from any GCAAR office location. If this happens, make sure to contact SentriLock first, to confirm that 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
When showing properties, please close the lockbox once you've extracted the keys. If the lockbox is left open, it continues to drain the batteries. Upon leaving the property, open the lockbox 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.
