Because most keyless remotes, or fobs, must be sold or programmed through a dealership, keyless remotes can be expensive to replace. If you're struggling to get your remote to respond to your touch or if the buttons are becoming stuck, your problem might be easily solved with a little do-it-yourself spirit. Fixing your keyless remote can be as simple as cleaning the contacts, which is easy to do.

Things you need
- Mini Philips screwdriver
- Mini flathead screwdriver
- Isopropyl-alcohol (tape head cleaner)
- Cotton swabs
- Canned air
- New battery (optional)
- Small paint brush (optional)
- Metallic paint (optional)
- Conductive coating (optional)
Check your remote to see whether it is held together by a small Philips-head screw. If so, remove it. Look at the join seam that runs along the middle of your remote. Search for a small indentation in which your miniature flathead screwdriver can be inserted. If not, use the seam itself, and gently pry it apart with your flathead screwdriver.
Spray the inside of the remote with canned air to remove any debris. Remove the battery, and dispose of it unless it is relatively new. It should be replaced when you reassemble the fob.
Remove the button pad from the top of the remote, and using the alcohol with cotton swabs, clean around the buttons and the plastic frame it fits in to make sure it's clean. Lay it aside for it to dry.
Remove the remote's interior circuit board. Generally, the problem with remotes is that the contacts have worn thin and have ceased to make a proper electrical contact with the rest of the remote. These contacts are usually gold in colour. Clean these with the cotton swabs and alcohol. Reassemble your fob, and check to see whether it works.
Reopen the fob if the clean contacts did not make a difference. To rebuild the contact surface, do one of several things: First, use a tiny bit of metallic paint applied gingerly with a paint brush or build up the contact surface by rubbing it with a pencil. Another solution is to use conductive coating, which is available at electronic shops. Let it dry 12 hours before reassembling the fob and checking to see if it works.
Replace your battery, and close your key fob by pressing the two halves back together. It should click back into place. Replace any screws removed upon disassembly.
Tips and warnings
- If you are not comfortable repainting the contacts and have a domestic remote, try a keyless replacement pad. This is an insert that goes between the contacts and the buttons and improves their conductivity.
