Dead Coin Battery

The most frequent reason for a key fob to not unlock or lock the doors is a dead coin battery. It is also one of the simplest to fix because it can be replaced in just a few minutes. Use a new coin battery with the same size, voltage, and specifications as the original to avoid a faulty battery. Also, don't use batteries that have been exposed to clean water (rain, clean tap water or even soda) because this could damage the internal chip.

Set the meter to ohms and use one of its probes to connect to the negative terminal on your Dawn. Then, connect the second probe to a metal part of the chassis or engine. The reading should be near zero ohms.

A clicking noise is another sign of a weak Dawn battery. This is because starter solenoid, the accessories and the engine require low current while the starter solenoid demands high current.

Water Damage

Issues with Receiver Modules

If you have tried a new cell and the remote key fob does not work, it could be time to replace your receiver module. This component receives radio frequency signals from your key fob and converts them into commands for the car's electronic system. If the chip inside the module is damaged, the module will not be able communicate with the other modules of the vehicle.
