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

The SureLock is a universal add-on deadbolt that fits nearly any garage door opener and gives you a real locking bar plus a manual release. The LiftMaster 041A6102 is a replacement power lock built only for LiftMaster and Chamberlain RJO jackshaft openers, so it is the right part when an existing lock fails, not a general upgrade. Buy the SureLock to add locking to a standard opener; buy the LiftMaster only to restore a jackshaft setup that was designed for a power lock. Owners report the LiftMaster fits and works when matched to the correct opener, while the SureLock is praised for broad compatibility but needs 2 inches of track clearance.

• Choose the SureLock if you have a standard opener and want to add an automatic deadbolt with a manual release.
• Choose the LiftMaster 041A6102 if you own a LiftMaster or Chamberlain RJO wall mount opener and need to replace or restore its power lock.
