The key fob utilizes a small transmitter to send a short-range radio signal to a receiver in your vehicle. Its primary function is to allow your car to recognize the fob and then open its doors when you approach it and to start when you press the ignition button in.

Interference can occasionally interfere with communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it may prevent you from unlocking your vehicle.

It is also important to ensure that the fob is not exposed to soapy or water residue. Water can cause corrosion and disrupt the circuitry. If this is the case, you will need to clean it by using isopropyl or electronic cleaner prior to installing the new battery.

It is a good practice to test the function of the fob prior to driving the vehicle. Using a voltmeter, check the voltage of the new battery to see whether it is at an acceptable level.
