Dead Coin Battery

A dead battery for a coin is the most common reason of a key fob that isn't locking or unlocking the doors. It is also the simplest to fix as it can be replaced in just a few minutes. To avoid getting a faulty coin battery, make sure you choose a replacement battery that is the same voltage, size and specification as the original one. Also, don't use batteries that have been exposed to clean water (rain or clean tap water, or even soda) because this could damage the internal chip. If the key fob still doesn't work, try reprogramming the key with an original key, or visit an authorized dealer.

This is a frequent issue in older batteries, particularly when they haven't been recharged for a long period of time. To check if your battery terminals aren't corroded, you can use a multimeter to check the conductivity. Set the meter at ohms and touch one of its probes to the negative terminal of your Dawn. Then, you can connect the other probe to a plain metal part of the chassis or engine. The reading should be near zero ohms.

Another sign of a weak battery in your Dawn is clicking noise when you try to start the engine. This is because the starter solenoid and other accessories require high electric current, while the engine requires low current to work - this means that the battery cannot provide enough charge.

Water Damage

Water damage could be the reason behind the key fob suddenly stopped working. The key fob can be damaged by water if it is dropped in water or soaked in soapy water. You can clean the keyfob by using electronic cleaners or isopropyl alcohol, but you will need to replace the chip if it is fried.
