Fiat Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car to open doors or start the motor. However, the fob may not function due to a variety of reasons.

The most common cause of key fob failure is a dead coin battery. Other causes include water damage, a faulty module, and interference signals.

Dead Coin Battery

If your key fob battery is dead, the first step is to replace it. Use a button cell battery that has the same voltage, size, and specification as your old one.

If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it can be used again. The best way to do this is using the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water but remains inoperable it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these cases.

Water Damage

It is possible to get water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to get it working again by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely before putting in a brand 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 reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit or receive signals to the vehicle. This can be caused by dropping the key fob or through exposure to water. If the key fob is not working after water exposure it could be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob does not respond after cleaning it, it is likely that the module is faulty and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to cease functioning. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob is a crucial component of the anti-theft systems in your vehicle. It sends a signal to the immobiliser inside your car that tells it whether the key is legitimate. If the chip is damaged or broken, your car won't start.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this scenario, you will need an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts on a key fob can be damaged through heavy use. If they're broken or bent, the fob will not send any signals to the receiver modules in the car.

Modern fobs are equipped with rubber seals that keep out water. Immersing them in water, even if it's only an occasional drizzle or splash could damage the electronic chip.

The key fob has chip that communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in modern vehicles or the red key system in older ones. This chip needs to be replaced if it's damaged.

Faulty 12 Volt Battery

A damaged battery can cause the key fob to cease working. If this happens the car's computer cannot recognize that the remote is within the vehicle.

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

Place an electrical load for fiat 500 car keys a short time on the battery to check its capacity. This will remove approximately 1% of the surface charge. Then, measure the voltage once more. The better the battery's capacity is, the longer it will keep its voltage. Ideal is that it stays close to 12 volts over several minutes.

Problems with Radio Signal

This is the most frequent reason for keys not sending signals to a car. This problem can be solved by replacing the battery. It is however important to purchase a battery that has the same size and voltage as the original one.

The buttons are not impervious to destruction and can take a lot. The battery buttons and the contacts are fragile, so they can get bent or broken with rough usage.

Other transmitters or objects using the same frequency can also disrupt the signal. For instance, a light control panel in your home could transmit interference using the same frequency as key fobs utilize. This could cause interference with the remote control of your car.

Incorrect OBDII scan tool

There are a number of reasons why a scan tool may not work. Some are more complicated than others.

Professional scan tools allow a mechanic to observe the car's networks and run a range of self-tests. These tools can save you a lot of time, but are expensive and are out of reach for the majority of DIYers.

If your OBD2 scanner won't turn on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine there is a chance that a fuse has ruptured. This is one of the most common causes of failures in the scan tool. The easiest solution is to replace the fuse which has blown.
