Tired of that old garage door remote acting up? This 3-pack of LiftMaster replacements has you covered! These work with any LiftMaster or Chamberlain garage door opener made after 2011 that has that yellow learn button - you know, the Security+ 2.0 models. The 240mAh battery is seriously powerful and lasts forever, plus the third-gen smart chip makes them more compatible and efficient than older versions. They've been through over 100,000 tests (yeah, that's a lot!) so you know they're reliable. The Security+ 2.0 rolling code tech keeps your garage secure from thieves, and they work from over 164 feet away.
