Liftmaster 371lm Garage Door Remotes
The first letter in the model number will indicate the series. The 3 in this case indicates Chamberlain Liftmaster's newest Security+ ERT line. Note that this should not be confused with the original security plus line as they operate on different frequencies and are thus incompatible. Any model number of remote that begins with this 3 will be compatible with other remotes, keypads, or keychains in this series.
The last number in the model number indicates the type of remote. A Liftmaster 370LM, for example, indicates that it is a keychain remote. The Liftmaster 371LM is the one button configuration of transmitter. The 372LM, 373LM, and 374LM each add a button to their configuration. The 376LM and 377LM are wireless keypads. The number on the top left of the label indicates internal part codes. The number used on most 371LM remotes is IC: 2666A 1573.
The number on the top right is the date of manufacture and is indicated in a format such as 06/07. The FCC ID is the number at te bottom of the remote and is often indicated by FCC ID: HBW1573. This number is shared by multiple models of remote so it should not be used to determine compatibility with the Chamberlain Chamberlain Liftmaster 371LM line of remotes. The last code in on the text on the left most side and is 132C2000-7. This simply indicates the regulations quoted as required by the FCC.
Once you know which remote that you will need, you will need to program your Liftmaster 371LM remote. To program the 371LM, press the purple button on the back of the logic board. Right afterwords, press the black button on the 371LM clicker. If everything went well, your new remote should be fully functional with your garage door opener.
The Liftmaster 371LM should last for years without any maintenance. If any is needed, it is usually due to a dead battery. This can be easily fixed by inserting a screwdriver into the side panel to pry in into two pieces. You can then replace the button cell battery. This battery can be found at most supermarkets and hardware stores. For any other problems, it is almost always easier to buy a new garage door remote than to try and fix an old one.
