Remote pad- Garage Door Opener by Sears
I just bought a house with a Sears garage door opener. I don't know what the security code is. The remote has the following ID BYF 8S5129.537 and two more digits that I can't read. The house is 26 years old and I think it is the original opener. The tag on the back of the remote says Assembled in Mexico. Sears Roebuck and Co. Can anyone help?
