Water Damage

You could have water damage if your key fob was submerged in a puddle, pool or washing machine. You can usually get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before installing a new battery.

This can be caused by dropping the key fob or by water exposure. If your key fob has stopped functioning due to water exposure and you are unable to fix it if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob won't respond to cleaning, it's possible that the receiver module has issues and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The battery contacts on a key fob are very fragile and are susceptible to damage with hard usage. If they are bent, or damaged, the fob will not send any signals to receiver modules inside the vehicle.

Modern fobs are designed with rubber seals to keep out water. A splash of water or a light rain is fine however, submerging them in saltwater can cause damage to the chip's electronic components.

The key fob is equipped with chip that communicates with the immobilizer system of the vehicle to start it. The system utilizes the old red keys that were used in older vehicles or the cryptocoding system that is used in newer vehicles. The chip must be changed if it is faulty.

A faulty 12 Volt battery

A damaged battery can cause the key fob to cease to function. If this happens, the car's computer system will not be able to recognize that the remote is in the vehicle.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly then it's time to replace it.

Place an electrical load for a few seconds on the battery to test its capacity. This will eliminate 1percent of the surface charges. After that, measure the voltage. The better the battery's capacity, the longer it can keep its voltage. Ideally, it will remain close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for keys not sending signals to vehicles. This issue can be resolved by replacing the battery. It is crucial to purchase an identical battery voltage and dimensions as the original.

Fobs are subject to a lot of abuse, and they aren't impervious to destruction. The battery contacts and buttons are delicate which means they could be bent or broken by rough use.

Other transmitters or objects that use the same frequency may also interfere with a signal. For instance, a light-control panel in your home could transmit interference on the same frequency that key fobs use. This can interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons why a scan tool may not work. Some are more complicated than others.

Professional scan tools allow mechanics to look over the car's networks and conduct a variety self-tests. They can be huge time savers, but they can be expensive, and beyond the reach of most DIYers.

If your OBD2 scan tool isn't turning on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present it's likely that a fuse is blowing. This is one of the most frequent causes of failures in the scan tool. It is often simple to fix the issue by replacing the blown fuse.
