Sometimes the metal does mess with these devices. Make sure you have a strong battery in the unit. You can get a powered antenna to boost the signal. Don't lengthen the antenna as this changes the frequency of the unit. Or you can get an external receiver on a different frequency to compinsate. Thanks BB

Have a new craftsman garage door opener and a new chamberlain keyless entry pad. i cannot get the keyless entry pad to work


As you may know by now there are keypads and then there are keypads. They must be made to work together as there are some that are not compatible. Posting your model numbers might help a little.

Ladies / Gentlemen: I have a Craftsman 139.53975SRT1 Garage Door Opener. What is the correct keyless entry pad for this opener? Will a 139.53876 keyless entry pad work with this opener? Thank You! ...


The correct keypad for your opener is 139.53684. The 53876 keypad is an older technology and will not work correctly. If you program it you will find your remotes no longer work and if you reprogram your remotes the keypad will not work.

My lift master security plus keyless entry pad for the garage door no longer will open the garage door when I key in the four digit code. Can I reprogram the entry pad and if sohow?thank you


You can try programming it but first make sure the battery is good. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in any 4 digit code you like and press enter.

Reset Craftsman keyless entry pad.


What you are asking for is not possible. You need to call a garage door repair technician. They will drill a hole through the door and using a special tool can pull the rope to release the door.
