Trade in your old SentriLock lockboxes for a discounted Bluetooth box!

SentriLock is going cardless on January 1, 2022, which means you’ll want to start using the SentriKey™ Real Estate app NOW. AACAR and SentriLock are offering you a discounted trade-in program for $95 + sales tax. Upgrade your non-Bluetooth SentriLock lockbox by trading it in for a current-model Bluetooth SentriLock lockbox. 

  1. Contact AACAR at or (410) 544-4554 with the serial numbers of the lockboxes you would like to trade in.
  2. AACAR will confirm your lockboxes are eligible for trade-in with SentriLock.
  3. AACAR will schedule an appointment for you to pick up and pay for your new lockboxes.

This deal is only good for AACAR Members and valid through 12/31/21.

∗Please note the silver boxes will still continue to work.  Any non-bluetooth model could qualify, please email your serial # to to check.
