LiftMaster 841LM Automatic Garage Door Lock vs SureLock Automatic Garage Door DeadBolt

The LiftMaster 841LM is a myQ-connected deadbolt that locks and unlocks in step with a compatible LiftMaster opener, but owners and reviewers report it often fails after about a year when internal plastic gears and housing break. The SureLock is a simpler universal deadbolt that works with any opener and is controlled from your existing remotes, keypad and wall console. Buy the LiftMaster only if you already run a compatible LiftMaster opener and want app monitoring; otherwise the SureLock is the safer long-term pick.

• Choose the LiftMaster 841LM if you have a compatible LiftMaster opener and want the lock to work automatically with myQ app monitoring.
• Choose the SureLock if you have any brand of opener and want a deadbolt that ties into your existing remotes, keypad and wall switch.
