12 Companies Leading The Way In Fiat 500 Keys
Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors and start the engine. However, the fob could not function due to a variety of reasons.

A dead battery for the coin is the most frequent cause of the malfunction of a key fob. Other causes are water damage or a damaged module and interference signals.

Dead Coin Battery

If your key fob's battery has died, the first step is to replace it. Choose a new button battery with identical in size, voltage and specifications as the original.

If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can work wonders.

If the key fob hasn't been exposed to water but isn't working it could be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob through an OBDII scan could help in these instances.

Water Damage

If your key fob's battery has taken immersed in a pool or puddle or even a trip down the wash machine, you may have some water damage. You can usually get it working again by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea let the fob dry completely before putting in a brand new battery.

If your key fob has stopped working even after replacing the battery and programming it again, you might have a problem with the receiver module. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in the owner's guide. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that connects to the vehicle's system. If this chip becomes damaged, it will be unable to longer transmit and receive signals to the vehicle. Dropping the key fob can cause this, as can water exposure. If your key fob has stopped functioning due to exposure to water and you are unable to fix it by attempting to clean the chip using electronic cleaner or isopropyl ethanol.

If the key fob still does not respond after cleaning it, you can be sure that the module is defective and will need to be replaced. A damaged receiver module may also cause the remote control key to stop working. This is usually caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip in your key fob plays an important part in the anti-theft security system of your vehicle. It transmits a message to the immobiliser in your car to tell it if the key is valid. If the chip is damaged or broken, your vehicle will not start.

A defective chip can be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency in close proximity to your car. In this case you'll need an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts of a key fob can be damaged through heavy use. If they're bent or broken the fob will not be able to send any signals to the receiver modules in the car.

Modern fobs are equipped with rubber seals to keep out water. A splash of water or light rain is acceptable However, submerging them in saltwater may harm the chip's electronic components.

The key fob has a chip that communicates with the vehicle's immobilizer system to activate it. The system utilizes the old red keys for older vehicles or the cryptocoding system used in the latest vehicles. This chip will have to be replaced if it's damaged.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob not to function. The car's system will not recognize the remote if this happens.

Before replacing the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading drops dramatically then it's time to replace it.

Put an electrical load for a few moments on the battery to check its capacity. This will eliminate approximately 1 percent of the surface charge. Then, measure the voltage again. The longer the battery is able to keep its voltage steady greater is its capacity. Ideally, it will remain at or near 12 volts for several minutes.


The radio signal is not working properly. Radio Signal

This is the most common reason for keys not sending signals to cars. This problem can be solved by replacing the battery. It is crucial to buy a battery with the same voltage and dimensions as the original.

Fobs take a lot of abuse, but they're not impervious to destruction. The battery contacts and buttons could be damaged by rough handling.

Other transmitters or objects operating on the same frequency can interfere with the signal. A light control panel in your home, for example could interfere with key fobs that use the same bandwidth. This can affect the remote control of your car.

Problems with OBDII Scan Tool

There are many reasons why scanners may not function. Some are more complicated than others.

fiat ducato replacement key let mechanics to observe the car's network, and run various self-tests. These tools can save time, but they're expensive and out of reach for most 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 all fine, a fuse may have failed. This is one of the most common causes of scan tool failure. It is usually easy to fix the problem by replacing the fuse blowing up.
