Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that sends an electronic signal from the fob to the car to unlock doors or start the motor. The fob might stop working due to a variety of reasons.

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

Dead Coin Battery

If your key fob's battery has died, the first step is to replace it. Make use of a new button battery that is identical in size, voltage, and specification as the original.

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

If the key fob has not been exposed to water, but it is still not working, there may be a problem with the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner can aid.

Water Damage

If your key fob's battery has taken submerged in a pool or puddle or walked through the washing machine, you could be suffering some water damage. It is usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol.  fiat ducato key fob  to let the fob completely dry before installing the battery.

It could be that you have a defective module when your key fob ceases working after replacing the battery or updating. You can find reprogramming procedures for most remote key fobs on YouTube or in your owner's guide. 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 car's system. This chip will stop sending and receiving signals to the car when it is damaged. This could be due to dropping the key fob, or by water exposure. If the key fob stopped working after water exposure it may be possible to fix it by cleaning the chip using isopropyl alcohol or an electronic cleaner.


However, if the key fob does not respond after cleaning it it is likely that the module is faulty and will require to be replaced. A malfunctioning receiver could cause the key to cease to function. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

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

A malfunctioning chip could be caused by interference signals from other objects or weather conditions that are bad, or transmitters operating on the same frequency near your vehicle. In this situation you'll require an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts in the key fob are fragile and are susceptible to damage by repeated use. If they're bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs are equipped with rubber seals to keep out water. A splash of water or light rain is fine but submerging them into salt water could harm the chip's electronic components.

The key fob is equipped with the chip that connects to the vehicle's immobilizer in order to activate it. The system uses the old red keys for older vehicles, or the cryptocoding system found in newer vehicles. This chip needs to be replaced if it's damaged.

A faulty 12 Volt battery

A defective battery can cause the key fob to function. When this occurs the car's computer will not be able to recognize that the remote is within the vehicle.

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

Put an electrical load for a short time on the battery to test its capacity. This will eliminate 1% of the surface charges. Then, test the voltage again. The longer a battery can hold its voltage and the higher its capacity. Ideally, it will remain at 12 volts or less for several minutes.

Problems with Radio Signal

This is the most frequent cause of a key fob that stops sending signals to the car. This issue can be resolved by replacing the battery. It is crucial to purchase batteries that have the same voltage and dimensions as the original.

Fobs are subject to a lot of abuse, but they're also not indestructible. Contacts on batteries and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency could also interfere with a signal. For instance, a light-control panel that is near your home could transmit interference on the same bandwidth that key fobs utilize. This could affect the remote control in your car.

Incorrect OBDII scan tool

There are a number of reasons why a scanner might not work. Some are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network and run a range of self-tests. These can be real time savers, however they can also be very expensive, and beyond the budget of many DIYers.

If your OBD2 scan tool isn't turning on, make sure you 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 among the most common reasons for failure of the scanner. The simple fix is usually to replace the fuse that is blowing up.
