LiftMaster 041A6102 Power Door Lock Kit vs SureLock Automatic Garage Door DeadBolt

Buy the LiftMaster 041A6102 only if you own a compatible LiftMaster or Chamberlain wall-mount jackshaft opener (3800, 8500, RJO20 family) and its power lock has failed. It is a genuine OEM part that restores the automatic lock the opener expects, and owners of those systems report it drops in with the included template and screws. The SureLock is the better pick for everyone else: it is a universal automatic deadbolt that works with any opener, adds a manual release, and fits most sectional doors with 2 inches of track clearance. On build, the LiftMaster is a direct-fit metal assembly; the SureLock is a standalone bolt with its own hardware and instructions.

• Choose the LiftMaster 041A6102 if your wall-mount LiftMaster or Chamberlain jackshaft opener has a dead or missing power lock and you want the exact factory replacement.
• Choose the SureLock if you have a standard opener and want an automatic deadbolt that adds real locking security, works with your existing remotes and keypad, and includes a manual release.
