Chance are they set there remote when you were using yours. To reset your opener you need to clear all the codes on the back of your opener itself there is a square button purple or red depends on how old it is. Press and hold that button until the LCD light turns off. Press your remote to make sure it has stopped working. Then press the button again only for a sec until the light comes on and starts to flash then press your remote button. Repeat for each remote.

My Lift Master garage door will not close. It makes the closing noise but the door does not slide down. Whcan I talk to to fix this?


Sounds like you have a chain drive garage door opener and you hear a humming sound when you push the wall console. The motor is running but the chain does not move. You need to replace the gear & sprocket assembly.

How do I program the garage door opener?


You post again, what the model is of the opener, the car model, it looks like this control is in a car.

Most times you need the garage door remote, then you have to hold a button and the remote button to sync the two.

What ever you are trying to program, if this is a car, you need the manual.


If you need more help, you need to post the model number of everything.


Not every car, every opener is the same at programing.

Imagine that, life simple.
