Other factors can cause weak fob signals, such as interference from other devices that operate on the same frequency as your key fob. 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.
Finally, physical damage to your key fob could also interfere with the transmission of RF signals, which may result in poor performance and range. A blown fuse, a damaged or cracked buttons or bent fob case could affect the transmission of signals, causing the remote to fail to respond.
You can try to fix the problem by resetting the settings on your fob or by replacing the battery. If your fob is old and worn, it may be time to replace it.
