LiftMaster 877LM Wireless Keyless Entry Keypad
The Dedicated Keypad for Security+ 2.0™ Openers (Yellow Button)
Grant access to your home without a remote or key. The LiftMaster 877LM is the factory-original wireless keypad designed exclusively for LiftMaster, Chamberlain, and Craftsman garage door openers manufactured between 2011 and 2024.
Featuring a weatherproof flip-up cover and a backlit keypad, this unit lets you open your garage with a simple 4-digit PIN. It is the perfect solution for kids coming home from school, dog walkers, or when you just want to go for a run without carrying keys.
⚠️ Critical Compatibility Check
Is this the right keypad for you? The 877LM is NOT universal. It works strictly with openers featuring a Yellow Learn Button (Security+ 2.0).
- ✅ Works with: LiftMaster Models 8500, 8550, 8365-267, 8355, and any other unit with a Yellow Circle Learn Button (Security+ 2.0).
- ❌ Does NOT work with: New 2024+ models (White Button), or older units with Purple, Red, or Green learn buttons.
If you need a keypad for an older opener (Purple/Red/Green), you need the universal [LiftMaster 878MAX]. If you have a new opener with a White button, you need the [LiftMaster L979S].
Stop Hiding Keys Under the Mat Give your family (and the dog walker) secure, key-free access to your home. No more lost keys, just a simple 4-digit PIN.
Key Features
🔒 Security+ 2.0™ Encryption
Peace of mind at your fingertips. The 877LM uses the same advanced rolling code technology as your remotes, ensuring that your PIN code cannot be intercepted or hacked by intruders.
🌧️ Weatherproof Design
Built for the Canadian climate. The durable flip-up cover protects the keypad from rain, snow, and UV damage, while the illuminated keys make it easy to enter your code on dark, rainy nights.
⏱️ Temporary Guest PINs
Need to let a contractor or house sitter in? You can program a temporary 4-digit PIN that works for a set number of hours or door openings. Once the time is up, the code expires automatically, keeping your master PIN secure.
🚪 One-Touch Close
Leaving in a hurry? You don't need to enter your code to close the door. Simply press the ENTER button to close the garage door as you walk away (this feature works only when the door is already open).
