Question About Craftsman Garage Door Opener 41A5021-3C
Change opener frequency...

I am recently divorced and my ex still has the garage door opened. How would I change the frequency on the openes I have so hers does not work (preventing access to the home I legally own). Thanks.

0 Actually you can make your Openner forget all codes by pushing the program RED button on the unit for 6 seconds. There are instructions for this on a sticker pasted on the motor.
