A wireless keyless entry system for garage doors provides both convenience and security. Keypads like the LiftMaster 877LM and LiftMaster 877MAX wireless entry system help homeowners avoid lost keys while maintaining controlled access through secure PIN technology.

The LiftMaster 877MAX, which has now been replaced by the 878MAX, and the 877LM are similar products with a few important differences. Both are available at All Security Equipment along with additional access control accessories and garage security solutions.

LiftMaster 877MAX vs LiftMaster 877LM

Both keypad systems are manufactured by LiftMaster and are mounted near the garage door for PIN-based access. With these keyless entry systems, you can open your garage without a remote control or key. Some users pair them with additional backup access solutions such as key cards or mobile-based controls.

Below are the main differences between the two keypads.

Compatibility

LiftMaster 877LM

The 877LM works with Security+ 2.0 garage door openers that use the yellow LEARN button and yellow antennas.

LiftMaster 877MAX

The 877MAX is backward compatible with a wider range of openers. It works with Chamberlain and LiftMaster garage door openers manufactured after 1993 and equipped with photoelectric sensors. It is compatible with the yellow, purple, green, or red/orange LEARN buttons.
