Why won't it program?


Check batteries. Craftsman owners manual may have troubleshooting procedure. Door opener new? or just started happening? If new there may be a compatibility problem. These things are tricky to keep the Hackers out of your home. So a little persistence and understanding how it works will help.

We cannot use any of our remotes to open the garage door but the button on the inside will open it. we put a new battery in one of the remotes and that didn'twork. any suggestions


If the light in the wall control is flashing you need to press and hold the lock button for 3 seconds. If this is not the case it is most likely the logic board.

No response to remote on Liftmaster 1/3 HP model # 1245R


It has probablly lost sync.

Follow the procedure to reload the codes. One usually has to hit a reset button on the head and then follow a sequence to sync your remote to the head.

Craftman 315 3 button remote


Do you have any other remotes and do they work? Do you have a wireless keypad and does it work? It sounds like you have a bad logic board but a little more info will help.

I have a Craftsman 315 remote door opener. Model 139.53753 I put in a new battery and now it's doesn't work. How do you code it again? Thanks, rr


Push and release the learn button on the back of the opener. It will be a square button. A little light will come on next to the opener. Then press and hold the button on the remote that you want to program if there is more than one button. The lightbulb on the opener will blink once. If there is not a lightbulb installed, you will hear a click.

having all the remotes you want programed with you, find learn button on back of opener. hold button until little light goes out- no remote will work now, with each remote Press learn button once,Press big button on remote-light bulb on opener will blink on/off if bulb is working-do this each hand held-keyless is same way, put you 4 #'s in HOLD enter button-light bulb blinks on/off you have 15 sec. for each time you hit the learn button. also best to start off with new 9 volt battery before you start programing
