fiat 500 replacement key fob Panda key fobs contain transponder chips that send a signal to your car to open the doors and start the engine. However, the fob could be inoperable due to various reasons.

The most frequent cause of key fob malfunction is an inoperable coin battery. Other causes include water damage, an inoperative receiver module, and signal interference.

Dead Coin Battery

Replace the battery if your key fob has gone out of service. Use a new button cell battery with exactly the same size, voltage and specification as the old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to being used again. The trick is to use the paper towel and soak it in isopropyl, or electronic cleaner.

If the key fob has not been exposed how to program fiat 500 key fob water, but still does not work it could be due to a problem with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob with an OBDII scanner can help.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to fix it by taking the batteries off and cleaning the circuit board using rubbing alcohol. It's a good idea to 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 defective receiver module. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

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

If the key fob doesn't 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 not work. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is a crucial element of the anti-theft device in your vehicle. It sends a signal to the immobiliser inside your car that tells it whether the key is genuine. Your car will not start when the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency as your vehicle. In this situation the replacement fob will be needed.

Contacts for the battery that are damaged

The battery contacts on the fob's battery can be damaged by excessive usage. If they are bent or broken the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs have rubber seals that keep out water. A splash of water or light rain is fine but submerging them into saltwater could damage the electronic chip.

The key fob has an electronic chip that communicates with the immobilizer system of the vehicle, allowing it to start it. The system is based on the old red keys that were used in older vehicles or the cryptocoding system that is used in newer cars. If the chip is damaged it will have to be replaced.

Problems with 12 Volt Batteries

A defective battery can cause the key fob to cease working. When this occurs the car's computer cannot recognize that the remote is within the vehicle.

Before replacing the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically then it's time to replace the battery.

Place an electrical load for a short period of time on the battery to test its capacity. This will eliminate 1percent of the surface charges. Then, you can measure the voltage once more. The longer a battery is able to keep its voltage steady and the higher its capacity. Ideal is that it stays close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for the key fob not sending signals to vehicles. This issue can be fixed by replacing the battery. It is crucial to buy batteries that have the same voltage and dimensions as the original.

Fobs can take a lot abuse, and they aren't indestructible. The battery buttons and the contacts are fragile, so they can get bent or broken by excessive use.

A signal may also be interrupted by other objects or transmitters who use the same frequency. For instance, a light-control panel that is near your home could transmit interference on the same bandwidth that key fobs utilize. This could affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons scanner tools may not function. Certain are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network and run a range of self-tests. These tools can save a lot of time, but they are costly and are out of reach for the majority of DIYers.

If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape the chances are that a fuse is blowing. This is the most common reason for failure of the scan tool. It is usually easy to fix the issue by replacing the fuse that was blown.
