My metallic connectors inside key fob not attached to silicone button pad & have become detached - so the whole fob is no longer working. What is the best adhesive to try and re-attach the metal connectors to inhibit them from wondering around causing a mess?
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!
Clean both the metal buttons and the gold circles with a little bit of rubbing alcohol. You want them to be shiny metal again because that’s how your fob works to close the circuit for each button. You can use a paper towel or a clean cloth. Dry them off and use some clear tape to hold them in place on the circuit board where they need to be for your buttons to work.
@normlscrindy The bottom two buttons on FOB are not connected. 3 is the right number for a total of 5. Those “pads” are what closes the circuit when you push the button. Clean the contacts on the circuit board, as well as the pads, carefully with an eraser. Than place the buttons on the little nips on the FOB. You can just use a little bit of vaseline or other slightly sticky substance between the pads and the rubber for the FOB. With all 5 of the membrane pads back on the rubber, place the circuit board over it and assemble the FOB in such a way that the little contact pads are always on the bottom (let gravity help you). Once it is assembled the pads are being held in place simply by the board. They got nowhere to go. Of course, if you are in doubt use a very small amount of super glue on the rim of the contact to glue it to the “silicone button pad “
I also have this issue on a 2012 Ram key fobs. As a pair of them on ebay & else where are $13 & up, I plan on getting a new pair and swapping out the circuit board only from the old fobs to avoid having to reprogram them or at least till I find a way around the reprogram fee.
Take the fob apart. Careful not to lose the little steel discs. Remove all the little switch discs and set them to soak in an alcohol bath to remove any contamination. Use alcohol to clean the surface of the PC board. If needed, use a pencil eraser to remove any contamination or oxidation. Wipe off and allow the discs and PC board to thoroughly dry. Carefully place one little steel concave side down over each used switch target. Note: Many fobs do not have all the switches used. Place a strip of Scotch Magic Tape to cover all the discs and press down to make sure it adheres to the PC board with all the discs in place. Trim excess tape from around the PC board. Assemble the fob. Check each switch to ensure it can be heard operating as you push it. Try the fob. See: https://www.youtube.com/watch?v=dagH0ZN_… Thank you. Rich Knowles
