I recently helped my neighbor replace his garage door opener, and these controls and remotes are available from the old one. All were functioning when removed.
Craftsman garage door opener remotes, wall controls, and wireless keypad. These work with the openers that have a PURPLE LEARN button, and should also work on Liftmaster and Chamberlain openers with the purple learn button.
Keypad is model KE2227 / 139.53754-01
Craftsman OE remote is TX2028 / 139.53753 (the other appears to be an aftermarket remote but it worked fine with the system)
