The most commonly cited reason for key fob malfunction is the battery of the coin is dead. Other causes include water damage a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery if your key fob has died. Choose a new button battery with identical in size, voltage and specifications like the previous one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it will have to be cleaned before it is able to be used again. The best method is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water but still does not work it could be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could aid in these situations.

Water Damage

If your key fob took a bath in the puddle or pool or gone to the washing machine, it could have some water damage. It is usually possible to get it working by taking out the batteries and cleaning the circuit board using rubbing alcohol. It is best to let the circuit board completely dry before putting in a battery.

There are instructions for reprograming the majority of remote keys on YouTube or consult the owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The fiat bravo key fob has a chip which communicates with the vehicle's system. If the chip is damaged, it cannot longer send and receive signals to the vehicle. Dropping the key fob could cause this, Fiat A602 Key as can exposure to water. If your key fob stopped working due to exposure to water or water exposure, you might be able fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob does not respond to cleaning, it's possible that the component has issues and needs to be replaced. A malfunctioning receiver could cause the key to stop working. This is usually caused by electromagnetic interference.

A defective electronic chip

The chip inside your key fob plays an important role in the anti-theft system of your car. It sends a message to the immobiliser inside your car to inform it whether the key is genuine. If the chip is damaged or broken, your car won't start.

A malfunctioning chip could be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency near your car. In this case you'll need a new key fob.

Contacts for the battery that are damaged

The battery contacts of the key fob are delicate and may be damaged when used for long periods of time. If they are bent, or broken, the fob won't transmit any signals to receiver modules inside the vehicle.

Modern fobs are equipped with rubber seals to keep out water. A splash of water or a light rain is fine but submerging them into saltwater can damage the chip's electronic components.

The key fob contains an electronic chip that communicates with the vehicle's immobilizer in order to activate it. It uses the old red keys in older vehicles as well as the crypto coding system in modern vehicles. This chip will have to be changed if it is defective.

A faulty 12 Volt battery

A malfunctioning battery could cause the key fob to work. If this happens, the car's computer system will not recognize that the remote is within 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 decreases significantly then it's time to replace it.

To test the battery's power put an electrical load on it for a few minutes. This will take off approximately 1% of the surface charge. Then, you can measure the voltage. The better the battery's capacity, 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 main reason for the key fob not sending signals to cars. This issue can be resolved by replacing the battery. It is essential to purchase an identical battery voltage and dimensions as the original.

Fobs can take a lot abuse, and they aren't indestructible. The battery buttons and contacts are delicate and can be bent or damaged from excessive use.

A signal can also be disrupted by other transmitters or objects which use the same frequency. For instance, a light control panel near your home may send interference over the same frequency that key fobs use. This could interfere with the remote control of your car.

Afflicted OBDII scan tool

There are many reasons why a scan tool could not function. Certain are more complicated than others.

Professional scan tools enable mechanics to examine the car's systems and run a variety of self-tests. These tools can save time, but are costly and are out of reach for the majority of DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine there is a chance that a fuse has ruptured. This is the main cause of scan tool failure. It is generally easy to fix the issue by replacing the fuse blowing up.
