Fiat Panda key fobs contain transponder chips that send an alert to your car to open the doors or start the engine. The fob can stop functioning due to a variety reasons.

The most common cause of key fob failure is an inoperable coin battery. Other reasons include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Choose a new button battery with identical in size, voltage and specifications as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned before being used again. The best way to do this is using the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob isn't working despite not being exposed to water, it could be due to a glitch in the receiver module or in the internal electronic chip. In these instances it is possible that reprogramming the key fob using an OBDII scanner can assist.

Water Damage

If your key fob's battery has taken submerged in a puddle or pool or gone through the washing machine, you could be suffering some water damage. It's usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before putting in a brand new battery.

You may have a faulty module if your key fob stops working after replacing the battery or changing the programming. There are instructions for changing the programming of most remote keys on YouTube or refer to your owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates with the vehicle's system. If the chip is damaged, it will no longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or by exposure to water. If your key fob has stopped functioning due to exposure to water, you may be able to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob is still unable to not respond after cleaning it, there is a good chance that the module is defective and needs to be replaced. A damaged receiver module may also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.

A malfunctioning electronic chip

The chip that is embedded in your key fob is an essential component of the anti-theft systems in your vehicle. It sends a message to the immobiliser in your car that tells it if the key is valid. Your car will not start in the event that the chip has been damaged.

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.

Faulty Battery Contacts

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

Modern fobs come with rubber seals in order to keep out water. Immersing them in water, even if just an occasional drizzle or splash could damage the chip's electronic components.

The key fob contains chip that communicates with the immobilizer system of the vehicle in order to start it. The system is based on the red keys of older vehicles or the cryptocoding system that is used in newer cars. If the chip is damaged, it will need to be replaced.

A faulty 12 Volt battery

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

Before replacing the battery, you should test it with a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly the time is now to replace it.

Set an electrical load for a few moments on the battery to check its capacity. This will eliminate about 1% of the surface charge. Then take another measurement of the voltage. The longer the battery is able to hold its voltage greater is its capacity. Ideal is to hold close to 12 volts over several minutes.

Faulty Radio Signal

This is the most common reason for keys not sending signals to cars. The battery can be replaced to fix this problem. It is however important to purchase a battery that is the same voltage and size as the original one.

Fobs are subject to a lot of abuse, and they aren't indestructible. The battery buttons and contacts are delicate and are susceptible to being bent or damaged from rough use.

Other objects or transmitters using the same frequency may also interfere with the signal. For instance, a lighting control panel that is near your home could transmit interference on the same bandwidth that key fobs use. This could cause interference with your car's remote control.

Afflicted OBDII scan tool

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

Professional scan tools let mechanics to look over the car's network and perform various self-tests. These are real time savers, but they are also extremely expensive, and out of the range of most DIYers.

If your OBD2 scanner doesn't work examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's possible that a fuse has failed. This is one of the most common reasons for failure of the scanner. It is generally easy to fix the issue by replacing the fuse that was blown.
