fiat car keys replacement Panda Key Fob replacement car keys fiat 500

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

A dead battery for the coin is the most common reason for malfunctioning keys. Other causes are water damage or a malfunctioning module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob is dead. Choose a button battery with the same voltage, size and specifications as the old one.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to using it again. The best solution is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water but it is still not working it could be because of an issue with the receiver module or an internal electronic chip. In these situations you can reprogramme the fiat 500x key fob replacement fob using an OBDII scanner might aid.

Water Damage

If your key fob has gotten a bath in the pool or puddle or walked to the washing machine, it could have some water damage. It's generally possible to get it back in working order by taking the batteries off and cleaning the circuit board using rubbing alcohol. It is best to let the board completely dry prior to installing batteries.

If your key fob isn't working, even after replacing the battery and reconfiguring it, you may have a faulty receiver module. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob contains an electronic 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 can be caused by dropping the key fob, or through exposure to water. If the key fob stops working after exposure to water it may be possible to fix it by cleaning the chip with isopropyl ethanol or electronic cleaner.

However, if the key fob does not respond after cleaning it, it is likely that the component is damaged and needs to be replaced. A faulty receiver can also cause the key to stop working. This is usually due to electromagnetic interference.

Faulty electronic chip

The electronic chip inside the key fob is an important component of the anti-theft systems in your vehicle. It sends a message to the immobiliser in your car to tell it whether the key is legitimate. Your car will not start in the event that the chip has been damaged.

A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency near your car. In this scenario the fiat replacement key fob will be required.

Contacts to the battery are not working properly.

The battery contacts in a fiat multipla key fob are very delicate and could be damaged with hard usage. If they're bent or damaged, the fob will not send any signals to receiver modules in the vehicle.

Modern fobs have rubber seals to keep out water. A splash of water or a light rain is acceptable However, submerging them in saltwater could damage the chip's electronic components.

The key fob has chip that communicates with the immobilizer system of the vehicle in order to start it. This system utilizes cryptocoding systems in modern vehicles or the red key system in older models. The chip must be replaced if it's malfunctioning.

Problematic 12 Volt Battery

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

Before you replace the battery, you should test it with a a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly, it's time to replace it.

To test the battery's capacity test the battery's capacity by placing an electrical load on it for a few minutes. This will take away about 1% of the charge on the surface. Then measure the voltage again. The greater the battery's capacity, the longer it can keep its voltage. It should be at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. It is however important to buy a new battery with the same voltage and size as the original one.

Fobs aren't impervious to damage and can withstand a lot. Battery contacts and buttons can be damaged by rough handling.

Other transmitters or objects operating on the same frequency may also disrupt the signal. A light-control panel at your home, for example could interfere with key fobs which use the same frequency. This can interfere with the remote control of your car.

Afflicted OBDII scan tool

There are a number of reasons why a scanner could not work. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's networks and run various self-tests. These tools can save a lot of time, but they are costly and not accessible to most DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse has failed. This is one of the most common causes of scan tool failure. The simple fix is usually to replace the blown fuse.
