fiat 500 car key Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car in order to unlock doors or turn on the motor. However, the fob may not function due to a variety of reasons.

The most frequent cause of key fob failure is an inoperable coin battery. Other causes include water damages as well as a defective module and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned prior to being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will do the trick.

If the key fob has not been exposed to water but isn't working, there may be a problem with the receiver module or an internal electronic chip. In these cases it is possible to re-programme the key fob with an OBDII scanner could aid.

Water Damage

If your key fob has taken a bath in the puddle or pool or gone to the washing machine, you might have some water damage. It's generally possible to get it back in working order by getting rid of the batteries and cleaning the circuit board using ruby alcohol. It is a good idea to allow the fob to dry completely prior to installing a new battery.

If your key fob stopped working, even after replacing the battery and programming it again, you might have a problem with the receiver module. You can find the instructions for the reprogramming of most remote keys on YouTube or refer to the owner's manual. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit and receive signals to the vehicle. The key fob being dropped can cause this, as can exposure to water. If your key fob has stopped working due to exposure to water, you may be able to fix it if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob is still unable to not respond after cleaning it you can be sure that the component is damaged and will require to be replaced. A malfunctioning receiver module could also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential part of the anti-theft system in 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, the car will not start.

A faulty chip can also be caused by interference signals from other objects or weather conditions that are bad, or transmitters on the same frequency close to your vehicle. In this situation an upgrade to the fob will be required.

Contacts to the battery are not working properly.

The battery contacts on the fob's battery can be damaged by heavy usage. If they're damaged or bent, the fob will not send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals that keep out water. Immersing them in water, even if it's just a light drizzle or splash can harm the electronic chip.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to begin it. The system uses the old red locked keys in fiat 500 for older vehicles, or the crypto coding system in the latest vehicles. This chip will need to be replaced if faulty.

Problematic 12 Volt Battery

A malfunctioning battery could cause the key fob to function. When this happens the car's computer won't recognize that the remote is in the vehicle.

Before you replace the battery, test it using a an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly it's time to change it.

Set an electrical load for a few moments on the battery to determine its capacity. This will eliminate 1% of the surface charges. Then, you can measure the voltage again. The greater the battery's capacity is, the longer it will maintain its voltage. Ideal is that it stays at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for the key fob to stop sending signals to a car. The battery can be replaced to fix this issue. It is however important to buy a new battery that is the same size and voltage as the original.

Fobs can take a lot abuse, and they aren't impervious to destruction. The battery contacts and buttons could be damaged through rough handling.

The signal could also be affected by other transmitters or objects that operate on the same frequency. For instance, a light-control panel close to your home can send interference on the same frequency as key fobs utilize. This can affect the remote control of your fiat 500 car key cover.

Faulty OBDII Scan Tool

There are many reasons why a scanner may not work. Some are more complex than others.

Professional scan tools let mechanics to monitor the car's networks and run various self-tests. These can be real time savers, but they can be expensive, and beyond the reach of most DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If all is fine there is a chance that a fuse has failed. This is the most typical cause of scan tool failure. It is often easy to fix the problem by replacing the fuse blowing up.
