fiat 500 replacement key fob Panda key fobs contain a transponder chip which sends an alert to your car to open the doors and start the engine. The fob might stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery if the key fob is dead. Make use of a new button battery with exactly the same size, voltage and specifications as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to using it again. The best way to do this is using an old towel soaked in isopropyl or electronic cleaner.

If the key fob hasn't been exposed to water but it is still not working it could be a problem with the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner may help.

Water Damage

If your key fob has gotten an immersion in the pool or puddle or even a trip through the washing machine, you could be suffering some water damage. It's possible to get it back in working order by taking the batteries off and cleaning the circuit board with rubbing alcohol. It is a good idea to let the fob dry completely before installing a new battery.

You may have a faulty module when your key fob ceases working after replacing the battery or reprogramming. Reprogramming instructions are available for most remote key fobs on YouTube or in the owner's guide. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has the chip that communicates the vehicle's system. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. Dropping the key fob could cause this, as well as exposure to water. If your key fob has stopped functioning due to water exposure and you are unable fix the issue if you clean the chip with electronic cleaner or isopropylethanol.

However, if the key fob is still unable to not respond after cleaning it, there is a good chance that the component is damaged and must be replaced. A faulty receiver module can also cause the remote control key to cease functioning. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is an important part of the anti-theft system in your vehicle. It sends a signal to the immobiliser unit of your car to inform it whether or not the key is legitimate. If the chip is damaged or broken, the car will not start.

A damaged chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this situation, you will need an entirely new key fob.

Contacts of the battery may be damaged.

The battery contacts on the fob's key can be damaged through heavy use. If they are damaged or bent, the key fob will not send any signals to the receiver modules inside the car.

Modern fobs are equipped with rubber seals that keep out water. A splash of water or a light rain is fine However, submerging them in saltwater may harm the electronic chip.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in vehicles that are more modern or the red key system used in older ones. If the chip is defective it must be replaced.

A faulty 12 Volt battery

A defective battery can cause the key fob not to work. If this happens the car's computer won't recognize that the remote is in the vehicle.

Before you replace the battery, test it using a an voltmeter to gauge 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 a battery's capacity, place an electrical load on it for a couple of minutes. This will eliminate one percent of the surface charges. After that, take the voltage once more. The longer a battery can hold its voltage and the higher its capacity. It should be close to 12 volts several minutes.

Problems with Radio Signal

This is the most frequent reason behind a key fob that ceases to send signals to the car. This issue can be fixed by replacing the battery. It is essential to purchase a battery that has the same dimensions and voltage as the original.

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

A signal may also be interrupted by other transmitters or objects that operate on the same frequency. A light-control panel at your home, for instance could interfere with key fobs that have the same bandwidth. This could affect the remote control in your car.

Afflicted OBDII Scan Tool

There are a number of reasons why a scanner might not work. Some are more complicated than others.

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

If your OBD2 scanner won't start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse has blown. This is one of the most common causes of a scan tool failing. It is typically easy to fix the problem by replacing the fuse blowing up.
