Dead Coin Battery

If the battery in your key fob is dead, the first thing to do is replace it. Use a new button cell battery with exactly the same size, voltage and specification as the original.

If the key fob was exposed to water, spare Key for fiat 500 like a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. The best solution is to use a paper towel that has been soaked in isopropyl, or electronic cleaner.

If the key fob is not working despite being not exposed to water, it could be due to a problem in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob with an OBDII scan could help in these cases.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry before installing the battery.

If your key fob stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. There are instructions for spare key for fiat 500 changing the programming of most remote keys on YouTube or consult the owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer send and receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If the key fob is not working after water exposure it is possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or an electronic cleaner.

However, if the key fob still does not respond following cleaning, it is likely that the module is defective and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is a vital part in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car that tells it that the spare key For fiat 500 is valid. If the chip is damaged or broken, your car will not start.

A faulty chip can also be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency close to your vehicle. In this scenario, you will need a new key fob.

Contacts to the battery are not working properly.

The battery contacts of the fob's key can be damaged due to heavy use. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals that keep out water. A splash of water or a light rain should be fine However, submerging them in saltwater can cause damage to the electronic chip.

The key fob contains an embedded chip that communicates to the immobilizer system of the vehicle to start it. This system utilizes cryptocoding systems in vehicles that are more modern and the older red key system for older models. This chip will need to be replaced if it's damaged.

Faulty 12 Volt Batterie

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

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

Put an electrical load for a short period of time on the battery to test its capacity. This will remove 1percent of the surface charges. Then, you can measure the voltage. The longer the battery is able to keep its voltage steady, the better its capacity. Ideal is to hold at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery can be replaced to solve this problem. But, it is essential to buy a new battery that is the same size and voltage as the original.

Fobs aren't impervious to damage and are susceptible to damage. The battery contacts and buttons could be damaged by rough handling.

The signal could also be affected by other transmitters or objects that operate on the same frequency. For example, a light-control panel that is near your home could transmit interference on the same bandwidth that key fobs utilize. This could affect the remote control of your car.

Faulty OBDII scan tool

There are a number of reasons why a scanner could not work. Certain are more complicated than others.

Professional scan tools let mechanics to look over the car's network and perform various self-tests. These can be real time-savers, but they are also extremely expensive, and beyond the budget of most DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine, a fuse may have blown. This is among the most frequent causes of a scan tool failing. The easiest solution is to replace the fuse which has blown.
