I need a quick service call to program two factory-brand remotes to my belt-drive garage door opener and to swap the old 2016 coin-cell battery in one of them; you provide the battery. The wall console and opener are working fine, but the handheld transmitters lost their coding. Because I no longer have the printed manual, you’ll have to walk through the learn-button sequence on the motor head without it. Once both remotes reliably open and close the door from the driveway and the street, the job’s done. Please bring a fresh CR2016 battery and any basic tools you like to use; I’ve got a step stool on site if you need it. Quick, tidy, and confirmed working before you leave—simple as that.
