Fiat Panda key fobs contain transponder chips that send the signal to your vehicle to unlock the doors or start the engine. The fob can stop functioning for a variety.

A dead battery for the coin is the most frequent cause of malfunctioning keys. 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. Choose a button battery with the same voltage, size and specification as your old one.

If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. The best method is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.

If the key fob isn't working even though it is not exposed to water, it could be due to a glitch in the receiver module or in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan can aid in these situations.

Water Damage

If your key fob's battery has taken a bath in the pool or puddle, or taken a trip down the wash machine, you might have some water damage. You can usually be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the circuit board completely dry before putting in a battery.

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

Faulty Receiver Module

The key fob is equipped with an electronic chip that communicates with the car's system. If this chip becomes damaged, it can no longer transmit or receive signals to the vehicle. The key fob being dropped can cause this, as can exposure to water. If the key fob is not working after exposure to water, it may be possible to repair it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob doesn't respond to cleaning, it's likely that the module is in issues and needs to be replaced. A damaged receiver module may also cause the remote control key to stop working. This is often caused by electromagnetic interference.

Faulty electronic chip

The chip inside your key fob plays a vital role in the anti-theft system in your car. It sends a message to the immobiliser in your car to tell it if the key is valid. Your car won't start in the event that the chip has been damaged.

A malfunctioning chip can be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this situation the replacement fiat key fob will be required.

Contacts of the battery may be damaged.

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

Modern fobs come with rubber seals in order to keep out water. A splash of water or light rain should be fine however, submerging them in salt water could damage the electronic chip.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in the latest vehicles and the older red key system in older ones. If the chip is damaged it must be replaced.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob not to work. The car's computer won't recognize the remote when this occurs.

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

To test the battery's power test the battery's capacity by placing an electrical load on it for a few minutes. This will remove about 1% of the charge on the surface. Then, measure the voltage once more. The greater the battery's capacity and the longer it can keep its voltage. It is ideal to maintain at or near 12 volts for several minutes.

Problems with Radio Signal

This is the most common reason for keys not sending signals to the car. The battery could be replaced to fix this problem. It is important to buy a battery that has the same dimensions and voltage as the original.

Fobs can take a lot punishment, and aren't impervious to destruction. Battery contacts and buttons can be damaged through rough handling.

The signal could also be interrupted 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 bandwidth that key fobs utilize. This could cause interference with the remote control in your car.

The tool is not working properly. OBDII scan tool

There are many reasons a scanner tool may not function. Certain are more complicated than others.

Professional scan tools allow mechanics to monitor the car's network and conduct a variety self-tests. These are real time savers, but they can also be very expensive, and out of the budget of many DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse is blowing. This is the main reason for failures of the scanner. It is typically easy to fix the issue by replacing the fuse blowing up.
