How to Repair a Key Fob Loop

When the remote still works, it is easier to fix the key fob than buy a new one.

Some cars come with remote key fobs that allow car owners to lock and unlock doors, set the car alarm and open the trunk with the press of a button. In some instances, the remote itself may short out and no longer work requiring a replacement; however, sometimes the plastic casing breaks instead, separating the key fob from the key ring. Instead of purchasing an expensive replacement for a remote that still works, you can repair it yourself.

Slide the screwdriver or coin into the crack on the side of the key fob and pop the two pieces apart.

Drill two small holes into the plastic casing on the battery side of the key fob. The holes should be in the same location where the plastic broke off. Drill the holes all the way through to the interior chamber of the key fob.

Unbend the paper clip, if you are using it, and cut about 1 1/2 inches of wire to use as your new loop.

Insert the ends of the loop into the holes you drilled into the key fob cover. Pull the ends through the drilled holes until the loop is the correct size, no more than 1/4 inch.

Bend the ends of the wire around the inside edges of the key fob cover so they are not in the way.

Snap the two halves of the key fob back together and reattach the key ring to the key fob. Pull on the key ring to ensure the wire remains in place.

Things You'll Need:

  • Screwdriver or coin
  • Drill equipped with a small bit
  • 22-gauge wire or a paper clip
  • Wire cutters
  • Needle-nosed pliers


If you recover the broken section of the key fob, use a strong glue to reattach the plastic portion. You can also purchase new cases at a lower rate than purchasing the entire key fob.
