Dead Coin Battery

Replace the battery if your key fob has died. Use a brand new button battery that has identical in size, voltage and specification as the old one.

If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it will have to be cleaned before it can be used again. The best way to do this is using an old towel soaked in isopropyl, or electronic cleaner.

If the key fob has not been exposed to water, but isn't working it could be due to a problem with the receiver module or an internal electronic chip. In these cases you can reprogramme the fiat key fob with an OBDII scanner can aid.

Water Damage

You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. If the chip is damaged, it can no longer be able to send or receive signals to the vehicle. Dropping the key fob can cause this, as well as exposure to water. If the key fob is not functioning after exposure to water, it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob does not respond to cleaning, it's possible that the module has issues and needs to be replaced. A faulty receiver module can also cause the remote control key to not function. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip that is in your key fob plays a crucial role in the anti-theft system in your car. It sends out a signal the immobiliser unit inside your car to determine whether or not the key is genuine. The car won't start in the event that the chip has been damaged.

A malfunctioning chip can be caused by interference from objects, bad weather or transmitters located near your vehicle. In this instance it is likely that a new fob would be required.

The battery contacts of a key fob are very fragile and are susceptible to damage by repeated use. If they are damaged or bent, the key fob will not send any signals to the receiver modules inside the car.

Modern fobs feature rubber seals that block out water. Submerging them in water even if it's just the slightest splash or drizzle, can damage the chip's electronic components.

The key fob houses the chip that connects to the vehicle's immobilizer system to allow it to start. It uses the old red keys for older vehicles or the crypto coding system in newer cars. This chip will need to be replaced if damaged.

Faulty 12 Volt Battery

A defective battery can cause the remote to cease working. The car's computer will not recognize the remote when this happens.

Before replacing the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly, it's time to replace it.

Install an electrical charge for a short period of time on the battery to determine its capacity. This will remove about 1 percent of the charge on the surface. Then measure the voltage again. The higher the capacity of the battery and the longer it can keep its voltage. Ideal is that it stays close to 12 volts for several minutes.

Faulty Radio Signal

This is the most typical reason for a keyfob that ceases to send signals to the car. This issue can be resolved by replacing the battery. It is crucial to purchase batteries that have the same voltage and dimensions as the original.

The buttons are not impervious to destruction and can withstand a lot. The battery contacts and buttons are delicate and can be bent or damaged from excessive use.

Other transmitters or objects operating on the same frequency can disrupt 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.

Faulty OBDII scan tool

There are a variety of reasons why a scanner tool may not work. Certain are more complicated than others.

Professional scan tools enable a mechanic observe the car's network and perform various self-tests. These are real time savers but they are also extremely expensive, and out of the range of most DIYers.

If your OBD2 scan tool fails to turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, a fuse may have failed. This is among the most frequent causes of failures in the scan tool. It is often simple to fix the issue by replacing the fuse that has blown.
