Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. The fob could stop working for a variety of reasons.

The most common reason for key fob malfunction is the battery of the coin is dead. Other causes include water damage the receiver module is defective and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Make use of a button cell battery that has the same voltage, size and specifications as your previous one.

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

If the key fob is not working even though it is not exposed to water it could be due to a malfunction in the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob with an OBDII scanner may help.

Water Damage

If your key fob's battery has taken submerged in a puddle or pool or even a trip down the wash machine, you could be suffering some water damage. It is usually possible to repair it by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It's best to let the fob completely dry before installing a battery.

If your key fob isn't working even after replacing the battery and reprogramming it, you may have a problem with the receiver module. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob, or through exposure to water. If your key fob stopped working due to water exposure, you may be able to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

However, if the key fob continues to not respond even after cleaning it then it is likely that the module is defective and needs to be replaced. A damaged receiver can cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob plays an important part in the anti-theft security system of your car. It sends a signal the immobiliser unit inside your vehicle to tell it whether the key is legitimate. The car will not start if the chip is damaged.

A damaged chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this case, you will need an entirely new key fob.

Faulty battery contacts

The battery contacts on the key fob are delicate and may be damaged by repeated use. If they're broken or bent, the fob will not send any signals to the receiver modules in the car.

Modern fobs come with rubber seals that keep out water. Submerging them in water even if it's only a light drizzle or splash could damage the chip's electronic circuit.

The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle, allowing it to start it. The system is based on the old red keys that were used in older vehicles or the cryptocoding system found in newer cars. If the chip is defective it will have to be replaced.

Problems with 12 Volt Batteries

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

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly the time is now to replace it.

Put an electrical load for a few seconds on the battery to gauge its capacity. This will eliminate 1% of the surface charges. Then, measure the voltage again. The better the battery's capacity, the longer it can keep its voltage. The ideal is to keep it at or near 12 volts for several minutes.

Problems with Radio Signal

This is the main reason for a keyfob that stops sending signals to the car. The battery is able to be replaced to resolve this problem. It is essential to purchase a battery with the same dimensions and voltage as the original.

Fobs can take a lot punishment, and aren't impervious to destruction. Contacts and buttons on batteries can be damaged by rough handling.

Other transmitters or objects using the same frequency could also interfere with the signal. A light-control system in your home, for instance, may interfere with key fobs which use the same frequency. This could cause interference with your car's remote control.

Afflicted OBDII scan tool

There are many reasons why a scan tool may not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to look over the car's networks and run a range of self-tests. These are great time savers, however they are also extremely expensive, and out of the reach of most DIYers.

If your OBD2 scan tool fails to turn on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine the fuse could have blown. This is the most common cause of scan tool failure. The easiest fix is to replace the fuse that is blowing up.
