I keep one of these on my house keys and a 373LM in the car. Two remotes, same opener, never search for it.
Liftmaster
370LM Three-Button Keychain Garage Door Remote
Pocket-sized 315 MHz Security+ three-channel keychain transmitter. Same internals as the visor-mount 373LM, but in a compact key-fob form factor with a steel keyring loop. Pairs with any Liftmaster, Chamberlain, or Sears Craftsman opener that has a purple learn button.

Same Security+ pairing as the visor 373LM in a key-fob shell. If your opener has a green, orange, or red learn button instead of purple, order the 970LM keychain.
Programming the 370LM
Each button pairs independently — repeat once per button to control three different doors or gates from one keychain.
- Press the purple "learn" button on the side of the opener's motor unit. The indicator light stays on for 30 seconds.
- Within 30 seconds, press and hold one button on the 370LM until the motor light blinks twice.
- Repeat at each subsequent opener using a different button on the 370LM.
Each Security+ opener stores up to 8 button-pairings. Adding a 9th pairing erases the oldest in memory.
What customers say
★★★★★
The fob is genuinely small — fits next to my car key without bulking the ring. Range is identical to the visor remote.
