Chamberlain Liftmaster manufactures door openers and related controls under the trade names of Sears Craftsman, Raynor, Access Master, Do-It, Master Mechanic, and Steel Craft, plus many other private label brands. Each of the product lines are compatible with the others. The only difference is the name on the product and the part number.
As of January 2012, Chamberlain has discontinued several garage door remotes. They are now producing the 890MAX , 893MAX , 895MAX as a standard replacement for all operators with either a Green, Red / Orange, or Purple learn button.
Choosing your Liftmaster / Chamberlain Garage Door Opener Remote:
Finding a compatible transmitter for your garage door use to be very confusing. Now the easiest way of finding the remote your garage door opener is to identify if the garage door opener has a learn button on the logic board. This is on the back or side of the motor unit of your garage door. If it has a learn button order the
890MAX Keychain Remote ,
893MAX 3-button Visor Remote , or
895MAX Deluxe Visor Remote as a direct replacement.
An example learn button is indicated below:

The learn button will be a square button near the center of your Liftmaster logic board. If you have an older model Liftmaster garage door opener, then there will be a set of dip switches that are used to program your opener instead of a learn button. Liftmaster Commercial garage Door Openers or gate openers might be located differently. Below you will find a reference for the different models of Chamberlain Liftmaster garage door remotes:
