Don't Make This Silly Mistake You're Using Your Fiat 500 Key…

fiat key fob replacement (content) Panda Key Fob Replacement

fiat 500 keys Panda keyfobs are equipped with a transponder, which sends a signal from the fob to the car that allows it to unlock doors or start the motor. However, the fob can be inoperable due to various reasons.

The most commonly cited reason for key fob malfunction is the battery of the coin is dead. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

If your key fob battery has gone out of service, the first thing to do is replace it. Use a brand new button battery that has exactly the same size, voltage and specifications as the original.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned before being used again. The best method is to use the paper towel and soak it in 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 situations it is possible to re-programme the key fob with an OBDII scanner can help.

Water Damage

You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. You can usually get it working again by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the fob completely dry prior to installing batteries.

You may have a faulty module in the event that your key fob stops working after replacing the battery or reprogramming. You can find the instructions for changing the programming of most remote keys on YouTube or refer to the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This can be caused by dropping the key fob, or by water exposure. If your key fob isn't functioning due to water exposure, you may be able to fix it by attempting to clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob still does not respond following cleaning, you can be sure that the receiver module is not functioning properly and will need to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This usually happens due to electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob plays an important role in the anti-theft system of your car. It transmits a signal to the immobiliser device in 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 can also be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency close to your vehicle. In this case you'll require a new key fob.

Contacts with the battery may be damaged.

The battery contacts on the fob's key can be damaged by heavy usage. If they are broken or bent, 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. Submerging them in water, even if it is just small splash or drizzle could harm the chip's electronic circuit.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system in order to begin it. The system utilizes the red keys of older vehicles or the cryptocoding system used in modern vehicles. This chip will have to be replaced if defective.

Faulty 12 Volt Battery

A defective battery can cause the key fob not to work. The car's computer may not recognize the remote when this happens.

Before replacing the battery, you should test it with a the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly it is time to replace the battery.

Put an electrical load for a few moments on the battery to gauge its capacity. This will take away about 1% of the surface charge. Then, you can measure the voltage. The longer a battery can keep its voltage steady, the better its capacity. The ideal is to keep it at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason behind a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. But, it is essential to buy a new battery with the same voltage and size as the original.

Fobs aren't indestructible and can withstand a lot. Battery contacts and buttons can be damaged through rough handling.

A signal can also be affected by other objects or transmitters which use the same frequency. For instance, a light-control panel close to your home can send interference on the same bandwidth that key fobs utilize. This could interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons why a scanner tool may not perform. Certain are more complicated than others.

Professional scan tools permit mechanics to look over the car's networks and run a range of self-tests. These tools can help save time, but they are costly and are out of reach for the majority of DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK there is a chance that a fuse has ruptured. This is among the most common causes of failures in the scan tool. The easiest fix is to replace the blown fuse.
