"Metallic connectors inside key fob not attached to silicone button pad"に関する回答as a locksmith, we see this problem often. we clean the board with alcohol pads after removing the battery. remove all discs from the back of the silicone pad. be sure to clean/scrape the contact cement off the back of the discs. once everything is clean, center each disc over the circuit it was intended to touch. get a 3” strip of clear commercial tape. have someone give the “non” sticky side a quick spray with anti static spray. the discs will move if not done. lay the tape over the top of the entire board and cut away any excess around the edges. reinstall your battery and you should be good to go afterwards. there’s no place for those discs to slide around after taping them in place. hope this helped!
