Want to change the code of the motor and remote controls need to change the code with which the remote opens the garage door

You cannot change codes. If you erase all the codes from the memory and then reprogram everything you will be right back where you were. If you want to eliminate one remote so that it no longer will work with your unit you can locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and hold this for 6 seconds. Now none of your remotes will work. To program it for your remotes you need to hold the button on a remote while you press and immediately release the smart/learn button. Do this for each remote.

This problem was exposed on a popular news program some ten years ago. There's a number code inside the remote that you have to change, and set the garage door opener to the same code. It should solve the problem.

Only opens when remotes are close

The problem is in the receiver on the logic board. You will have to replace the logic board. You can get a replacement part at Thanks BB

Door opener remotes not opening garage door.

You have to sync the remotes to the new code. For older remotes, you can open the remote and match the pin settings.

For newer remotes there's a button that you push in the back of the opener that sets in program mode (for Chamberlain). When you push the remote button, it will acknowledge the remote is programmed.

If this doesn't help, comment back on your particular model and we'll help you with the solution.

didnt try everything cause if you did, it would work! Get two people and garage door opener. One read manual from car under Garage door" or Homelink while other pushes button. When manual says if this did not work or if you have security plus or rolling code, continue with other instructions. You will need a working remote and will need to pushh learn button on motor logic board.
