Key Fob Replacement and Repair

The key fobs found in modern automobiles perform a lot of work and are subject to lots of abuse. Sometimes, just a simple repair or replacement is all you need to make them functional again.

Most fobs use flat watch-style batteries, which are easy to find in auto parts retailers. Before calling in a professional, you can do some of the DIY fixes.

Dead Key Fob Batteries

Weak Signals

If you find that your key fob isn’t responding to the buttons on the remote, it could be an indication of a problem with signaling. Radio signals are used to transmit information between your car and the key fob. Weak or inconsistent radio signals can lead to poor performance and a limited range.

Examining the battery level of your fob is a good idea, because it could significantly affect the sensitivity of your signal. It is also recommended to reset the settings on your fob, which can help to restore an even and consistent response from the car. The procedure differs from vehicle to vehicle, so the owner’s manual or call to the help line of the manufacturer is probably the best resource here.

Other factors, such as interference from other devices that operate at the same frequency can also contribute to weak signals. Power lines, other key fobs, wireless communication devices, and even cellular networks can interfere with the RF (radio frequency) signals that your key fob uses to connect to the receiver in your vehicle.

Physical damage to your keyfob can also interfere with the transmission of radio signal, leading to lower performance and less range. A blown fuse, a broken or cracked button or a bent case of the fob may affect signal transmission and cause the remote not to function properly.
