Fiat Panda key fobs contain a transponder chip that sends the signal to your vehicle to open the doors and start the engine. However, the fob can be inoperable due to various reasons.

A dead battery for the coin is the most common cause of the malfunction of a key fob. Other causes include water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

If your key fob's battery has died, the first thing to do is replace it. Use a button cell with the same voltage, size and specifications as your previous one.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it's going to need to be cleaned before it can 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 has not been exposed to water, but isn't working it could be an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner might assist.

Water Damage

If your key fob's battery has taken immersed in a pool or puddle or walked down the washing machine, you may have some water damage. It's possible to repair it by taking the batteries off and cleaning the circuit board with rubbing alcohol. It's a good idea to let the fob dry completely before installing a new battery.

There could be a problem with the module in the event that your remote stops working after replacing the battery or replacing it with. There are instructions for changing the programming of most remote keys on YouTube or in your owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or through exposure to water. If your key fob has stopped working due to water exposure or water exposure, you might be able to fix it if you clean the chip with electronic cleaner or isopropylethanol.

If the key fob does not respond to cleaning, it's possible that the module has a fault 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.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential part of the anti-theft system in your car. It transmits a signal to the immobiliser unit inside your car to determine whether or not the key is in fact valid. If the chip is damaged or broken, your vehicle won't start.

A faulty chip may also be caused by interference caused by objects, bad weather or transmitters near your vehicle. In this situation an upgrade to the fob will be required.

Contacts to the battery are not working properly.

The battery contacts inside a key fob are very delicate and can get damaged when used for long periods of time. If they are bent, or damaged, the fob will not send any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals that block out water. A splash of water or light rain is acceptable but submerging them into saltwater may harm the chip's electronic components.

The key fob contains chips that communicate with the vehicle's immobilizer to allow it to allow it to start. This system makes use of cryptocoding systems in modern vehicles as well as the traditional red key system for older models. This chip needs to be changed if it is damaged.

The 12 Volt Battery is faulty

A defective battery can cause the key fob to function. The car's computer will not recognize the remote when this happens.

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly then it's time to replace it.

To determine the capacity of a battery, place an electrical load on it for a couple of minutes. This will take away 1percent of the surface charges. After that, measure the voltage. The longer a battery is able to hold its voltage and the higher its capacity. The ideal is to keep it at or near 12 volts for several minutes.

Faulty Radio Signal

This is the main reason for the key fob to stop sending signals to the car. This problem can be solved by replacing the battery. It is crucial to purchase an identical battery voltage and dimensions as the original.

The buttons are not impervious to destruction and can withstand a lot. Contacts and buttons on batteries can be damaged by rough handling.

A signal can also be impacted by other objects or transmitters which use the same frequency. A light-control panel at your home, for example could interfere with key fobs that use the same frequency. This could affect the remote control of your car.

Afflicted OBDII scan tool

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

Professional scan tools let a mechanic observe the car's network and perform various self-tests. These can be real time savers, however they can be expensive, reprogram and out of the range of most DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse is blowing. This is the most frequent cause of scan tool failure. It is typically easy to fix the issue by replacing the fuse that has blown.
