Weak Signals

If you find that your key fob isn't responding to buttons on the remote, this can be an indication of a problem with the signaling. Radio signals are used to transmit information between your car and the key fob. Inconsistent or weak radio signals can result in poor performance and range.

Examining the battery level of your fob is a good idea, as it can significantly affect the sensitivity of your signal. Resetting the settings on the fob can aid in restoring a more constant response. The procedure will differ from vehicle to vehicle. The owner's guide or a call to the manufacturer's support line is your best resource.

Other factors, including interference from other devices that operate on the same frequency, can also contribute to weak signals. Other key fobs as well as wireless communication devices could interfere with the RF (radio-frequency) signals that your key fob sends to connect to the receiver of your vehicle.

Additionally physical damage to your key fob may hinder the transmission of RF signals which may result in poor performance and range. A blown fuse, damaged or cracked button, or a bent case of the fob could affect signal transmission and cause the remote to respond.
