what keypad are you using with new opener? Frequency has changed. can't use old one. you probably never needed to change things; just needed to follow proper coding procedures.

SOURCE: Need to reprogram keypad for garage door opener

On the rear of the g. door opener, there is a learn buttom.

The first step is to push this button in.

Then go to the remote and enter the new code you want

Press and hold the enter button.

The lights will blink and or you will hear two clicks.

The code you entered should be learned and ready to use

SOURCE: Chamberlain Garage Door opener model 3850.

The blinking lights are normal when you enter a code and press enter. I would try programming it and if that doesn't work replacing it. To program it you press and immediately release the smart/learn button on the rear of the motor unit and then key in your 4 digit code and press enter.

Sounds like the receiver in your opener has quit working. Unless you break in you need to call a door technician. They can drill a hole in the door, use a special tool to pull the manual release and open the door. You should then have them install a keyed manual release if this ever happens again. They can also repair or replace your opener.

The button on wall which has a little green lite in the center, keeps blinking, but the garage door does open


Press and hold the lock button for 3 seconds to stop the light from blinking. That blinking is the indication that the lock function is on and your remotes will not work.
