A Fiat 500 Keys Success Story You'll Never Imagine

Fiat Panda Key Fob Replacement

fiat 500 replacement key cost Panda keyfobs are equipped with a transponder that sends an electronic signal from the fob to the car in order to unlock doors or start the motor. The fob might stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery if your key fob has gone out of service. Make use of a button cell battery that has the same voltage, size, and specifications as your previous one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will do the trick.

If the key fob is not working even though it is not exposed to water it could be due a malfunction in the receiver module or in the internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these instances.

Water Damage

There could be water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely before installing a 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 the instructions for the reprogramming of most remote keys on YouTube, or consult your owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as could water exposure. If the key fob has stopped working after water exposure it may be possible to fix the issue by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob does not respond to cleaning, it's possible that the receiver module has issues and needs to be replaced. A malfunctioning receiver could cause the key to cease to function. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential element of the anti-theft device in your vehicle. It sends a signal to the immobiliser inside your car to tell it whether the key is legitimate. If the chip is damaged or broken, your car will not start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this case it is likely that a new fob would be needed.

Faulty battery contacts

The battery contacts on a key fob can be damaged by heavy usage. If they're damaged or bent, the replacement key for fiat 500 fob won't send any signals to the receiver modules in the car.

Modern fobs have rubber seals that block out water. A splash of water or light rain is acceptable but submerging them into saltwater may harm the chip's electronic components.

The key fob is equipped with the chip that connects to the vehicle's immobilizer system in order to activate it. This system uses crypto coding systems in vehicles that are more modern and the older red key system used in older ones. If the chip is not working properly it must be replaced.

The 12 Volt Battery is faulty

A damaged battery could cause the key fob to function. When this happens the car's computer will not recognize that the remote is in the vehicle.

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

To test a battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away about 1 percent of the surface charge. After that, take the voltage once more. The longer a battery can hold its voltage, the better its capacity. Ideal is to hold close to 12 volts during several minutes.

The radio signal is not working properly. Radio Signal

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

Fobs are subject to a lot of punishment, and aren't impervious to destruction. Contacts on batteries and buttons can be damaged through rough handling.

A signal can also be interrupted by other transmitters or objects which use the same frequency. A light control panel in your home, for instance, may interfere with key fobs using the same bandwidth. This could affect the remote control of your car.

Incorrect OBDII Scan Tool

There are a number of reasons why a scanner could not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to examine the car's systems and run a variety of self-tests. These tools can save time, but they're expensive and not accessible to most DIYers.

If your OBD2 scan tool won't power on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're all fine there is a chance that a fuse has ruptured. This is the most typical reason for failure of the scan tool. The most straightforward fix is to replace the fuse that is blowing up.
