Dead Coin Battery

The most frequent reason for a key fob to not lock or unlock the doors is a dead battery. It is also the most simple to fix since it can be replaced in just several minutes. Use a new coin battery with the same size, voltage, and specification as the original to avoid a faulty battery. Never use a battery exposed to clean water, such as rain, clean tap-water, or even soda, since it could cause damage to the internal chip.

Multimeters are a good tool for assessing the conductivity of your battery to determine if your battery's terminals are corroded. Set the meter to ohms and use one of its probes to connect to the negative terminal of your Dawn. The other probe should be placed on the surface of the engine or chassis. The reading should be near zero ohms.

Another indication of a weak battery in your Dawn is a clicking sound when you attempt to start the engine.

Water Damage

If the chip in the module is damaged, it will not be capable of communicating with other modules inside the vehicle. To identify the issue you'll require an OBD scanner that will reveal what the onboard computer is telling it to do.

The clips made of metal that hold the battery in the key fob for your Dawn complete the circuit and keep it in place. These clips can get corroded and make the battery's contacts ineffective. When replacing the battery, ensure that it's exactly the same size and voltage as the original. Otherwise it could cause damage to the chip inside the key fob.
