Can you help me reprogram the key pad on my garage door opener? I don't have the previous code for my model 139.53675srt2 part 41a50212c. Please help.
I tried to to reset the opener doing what it said on the key pad itself, but it won't work with us not knowing what the previous number was. The previous owner lives in china and doesn't remember it.

I am sending you an image showing programming a new code into your keyless entry.
To eliminate the possibility of someone using the previous code, erase all the codes from the logic boards memory. On the back of the motor unit press and hold the learn button until the led goes off. This will erase all codes in the memory of the logic board. You will have to program each remote and the keyless entry after erasing the codes.
