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.

Ocasionally my garage door will open by it's self, how do I stop this problem. It's a Sears Craftsman model #139.535355SRT1, 1/2hp .


Somebody in the neighborhood probably has a remote that is on the same code as yours. Try changing your codes first, to see if problem stops. Consult the owner's manual for code instructions.

A transmitter nearby can also create noise on the remote push button switch as well, and perhaps trigger the door to cycle. You should be able to disconnect the pushbutton switch at the opener, and use remotes until satisfied that problem has been corrected. If this is the case, talk to Tech Support line (again, in manual) about reducing noise / interference susceptibility.

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.

Reprogram a keyless entry remote control for a liftmaster


MOST OF THE WIRELESS KEYPADS YOU DON'T NEED THE OLD CODE TO PROGRAM A NEW ONE.
JUST PRESS THE LEARN/PROGRAM BUTTON AND RELEASE YOU NOW HAVE 20 SECONDS FOR HER TO PUNCH IN THE CODE SHE WANTS AND PRESS AND HOLD ENTER. THE NEXT TIME SHE PRESSES THE BUTTON THE DOOR SHOULD WORK.

NOTE IT WILL WORK FOR ABOUT 20 SECONDS AFTER ENTER IS PRESSED THE FIRST TIME. AFTER THAT YOU NEED TO RE-ENTER THE CODE AND PRESS ENTER.
PROBLEM SOLVED HAPPY NEIGHBOR!!
