How do I program a transmitter to work on a Craftsman model 139.53645 SRT2 Garage Door Opener?
To program a transmitter/remote, do the following:
1. Press and hold the selected remote push button.
2. Then press and release the "SRT" (learn) button on the back panel of the opener. The opener light will flash once.
3. Release the remote push button.
Now the opener will operate when the remote control button is pressed.
If you decide to use a different remote control button than originally programmed into the opener, you need to erase all the learned codes and reprogram each remote control used to operate the garage door opener.
To erase all codes:
1. Press and hold the "SRT" button on the opener panel until the indicator light turns off (about 6 seconds). All the codes the opener has learned will be erased.
2. Repeat steps 1,2, and 3 above for each remote control in use.
The programming procedures are also listed in the Owners Manual and on the Opener panel.
