If the key fob hasn't been exposed to water, but remains inoperable it could be an issue with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob using an OBDII scanner could assist.

Water Damage

If your key fob has gotten an immersion in the pool or puddle or gone to the washing machine, it could have some water damage. It's possible to get it working by taking the batteries off and cleaning the circuit board using ruby alcohol. It is best to let the circuit board completely dry before installing a battery.

Modern fobs are designed with rubber seals to keep out water. Submerging them in water, even if it is just the slightest splash or drizzle could damage the chip's electronic components.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle in order to start it. It uses the old red keys that were used in older vehicles as well as the cryptocoding system used in the latest vehicles. If this chip is faulty it will have to be replaced.

Faulty 12 Volt Battery

A defective battery can cause the key fob to stop working. When this happens the car's computer cannot recognize that the remote is within the vehicle.

Before replacing the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically, it is time to replace the battery.

To test the battery's power to determine its capacity, put an electric load on it for a couple of minutes. This will take away about 1% of the surface charge. After that, take the voltage again. The longer the battery is able to hold its voltage greater is its capacity. Ideal is that it stays at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent reason behind a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. However, it is crucial to buy a new fiat 500 key battery that has the same size and voltage as the original one.

The buttons are not impervious to destruction and are susceptible to damage. Contacts on batteries and buttons can be damaged through rough handling.

Other objects or transmitters using the same frequency may also disrupt a signal. For example, a light-control panel close to your home can send interference on the same frequency that key fobs utilize. This could interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons a scanner tool may not function. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's networks and conduct a variety self-tests. These are great time-savers, but they're also expensive and are out of the reach of most DIYers.
