fiat ducato key fob replacement Panda Key Fob replacement key for fiat ducato van

fiat 500x key Panda key fobs contain an transponder chip that transmits a signal to your fiat car key to open the doors or start the engine. The fob can stop functioning due to a variety reasons.

The most frequent cause of key fob malfunction is a dead coin battery. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has failed. Choose a new button battery that has identical in size, voltage and specifications as the original.

If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can be the solution.

If the key fob has not been exposed to water but still does not work it could be due to an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan could help in these instances.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It is usually possible to repair it by removing the batteries and cleaning the circuit board with ruby alcohol. It is best to allow the device to completely dry prior to installing a battery.

If your key fob isn't working, even after replacing the battery and reprogramming it, you may have a malfunctioning receiver module. You can find the instructions for reprograming the majority of remote keys on YouTube or refer to your owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the car's system. If this chip becomes damaged, it can no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob or due to exposure to water. If the key fob has stopped working after exposure to water, it is possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob won't respond to cleaning, it's possible that the component has an issue and must be replaced. A damaged receiver can cause the key to stop working. This is often caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip in your key fob is an important part of the anti-theft system in your car. It sends a message to the immobiliser in your car to determine if the key is valid. If the chip is damaged or broken, the car won't start.

A faulty chip can also be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency as your vehicle. In this case, you will need a new key fob.

Contacts for the battery that are defective

The battery contacts of a key fob are very fragile and are susceptible to damage with hard usage. If they are bent or broken the fob will not send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals in order to keep out water. A splash of water or a light rain is acceptable however, submerging them in saltwater can cause damage to the electronic chip.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. This system makes use of cryptocoding systems in the latest vehicles and the older red key system used in older models. This chip will need to be replaced if damaged.

Problematic 12 Volt Battery

A damaged battery can cause the remote to cease working. The car's computer will not recognize the remote if this happens.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly then it's time to replace it.

To test the battery's power, place an electrical load on it for a couple of minutes. This will take away one percent of the surface charges. Then, you can measure the voltage once more. The longer the battery can hold its voltage, the better its capacity. Ideally, it should remain close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason for keys not sending signals to the car. The battery could be replaced to fix this problem. It is crucial to buy batteries that have the same dimensions and voltage as the original.

Fobs take a lot of punishment, and aren't indestructible. The battery buttons and the contacts are fragile and are susceptible to being bent or broken by excessive use.

Other transmitters or objects using the same frequency can also interfere with a signal. For example, a light-control panel close to your home can send interference over the same frequency as key fobs use. This could cause interference with the remote control of your fiat car key cutting.

Afflicted OBDII Scan Tool

There are a variety of reasons why a scanner tool may not function. Certain are more complicated than others.

Professional scan tools permit mechanics to observe the car's networks and conduct a variety self-tests. These are great time savers, but they can be expensive, out of the budget of most DIYers.

If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape the chances are that a fuse has blown. This is among the most common causes of scan tool failure. The simple fix is usually to replace the fuse that is blowing up.
