replacement fiat key Panda Key Fob replacement fiat 500 Key fob

fiat ducato replacement key Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car in order to unlock doors or start the motor. The fob might stop working for a variety of reasons.

A dead coin battery is the most frequent reason for key fob malfunctions. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob battery has died, the first step is to replace it. Choose a button battery with the same voltage, size, and specifications as the old one.

If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it will have to be cleaned before it can be used again. The best method is to use a paper towel soaked with isopropyl, or electronic cleaner.

If the key fob has not been exposed to water, but remains inoperable, there may be an issue with the receiver module or an internal electronic chip. In these cases it is possible to re-programme the key fob using an OBDII scanner could help.

Water Damage

If your key fob took immersed in a pool or puddle or walked down the washing machine, it could have some water damage. It's usually possible to get it back in working order by removing the batteries and cleaning the circuit board with ruby alcohol. It's a good idea allow the fob to dry completely before putting in a new battery.

If your key fob stopped working, even after replacing the battery and reprogramming it, you may have a faulty receiver module. There are instructions for reprogramming most vehicles' remote keys on YouTube or in your owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates the vehicle's system. If this chip becomes damaged, it will no longer transmit or receive signals to the vehicle. Dropping the key fob can cause this, as well as exposure to water. If the key fob has stopped working after exposure to water it may be possible to fix it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

However, if the key fob continues to not respond after cleaning it it is likely that the module is faulty and must be replaced. A damaged receiver can cause the key to not work. This is typically caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside the key fob is an important element of the anti-theft device in your car. It transmits a signal to the immobiliser unit inside your car to determine whether or not the key is valid. The car will not start in the event that the chip has been damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters in the vicinity of your vehicle. In this instance you'll require an entirely new key fob.

Faulty Battery Contacts

The battery contacts of a key fob are very delicate and could be damaged by repeated use. If they're damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs feature rubber seals that block out water. Submerging them in water even if it's only an occasional drizzle or splash could harm the chip's electronic circuit.

The key fob is equipped with an electronic chip that communicates with the vehicle's immobilizer to allow it to start it. This system uses crypto coding systems in modern vehicles, or the old red key system for older ones. This chip needs to be changed if it is faulty.

Faulty 12 Volt Battery

A malfunctioning battery could cause the key fob to cease working. When this occurs, the car's computer system will not recognize that the remote is in the vehicle.

Before you replace the battery, test it by using a a voltmeter 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.

To test the battery's capacity to determine its capacity, put an electric load on it for a few minutes. This will remove approximately 1% of the charge on the surface. Then measure the voltage again. The longer the battery is able to keep its voltage steady, the better its capacity. Ideally, it should remain at 12 volts or less for several minutes.

Faulty Radio Signal

This is the most typical reason for a key fob to stop sending signals to the car. This issue can be resolved by replacing the battery. It is important to buy batteries that have the same dimensions and voltage as the original.

Fobs are subject to a lot of punishment, and aren't impervious to destruction. The battery buttons and contacts are brittle and can be bent or damaged by the force of.

The signal could also be interrupted by other transmitters or objects that use the same frequency. For instance, a lighting control panel near your home may send interference over the same bandwidth that key fobs use. This could affect the remote control in your car.

Incorrect OBDII Scan Tool

There are many reasons why a scanner might not work. Some are more complex than others.

Professional scan tools allow mechanics to look over the car's networks and perform a variety of self-tests. These can be real time savers, however they can also be very expensive, out of the reach of most DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the fuse could have blown. This is one of the most frequent reasons for failure of the scanner. It is often easy to fix the issue by replacing the fuse that has blown.
