Only 1 remote will prog. at a time CraftsmansOpener 139.53674SRT2
I have just replaced the batteries on both on my security+ "Three-Function Remote Control Units" and I can't get both remotes programmed. When I go to program both remotes I can only get one programmed at a time. I erased all remote control codes as outlined in manual. Manual says to go back and program each remote control unit one at a time by:
Remote control unit "A"
1. Pressing and hold the selected remote control push button.
2. Then press and release the SRT (learn) button on the back panel of the opener. (All indicator lights work as outlined)
3. Release the remote control push button.
This process resulted in the correct programming and remote works.
Remote control unit "B":
When I go to program the second remote according to the same instructions it will not accept the program or work. The indicators lights don't operate as they should.
I went back and erased all codes and programmed the remote that wouldn't program "Remote B", and it allowed the programing and worked. When I tried to program "Remote A", (this is the one that worked during the first programming try), it wouldn't take the programming.
Can anyone help me with this problem?
