I have a Chamberlain LiftMaster Professional garage door

Customer Question

I have a Chamberlain LiftMaster Professional garage door opener.
The light inside the activation button on the wall of the garage has begun flashing and as a result my remote opener in my car will not open or close the garage door. Pushing the activation button inside the garage still operates the opener.
What do I need to stop the flashing light inside the activation button?

Please disregard my question, I have repaired the problem myself. The lock feature had been accidently activated. Thank you.
