The Top 5 Reasons People Win With The Fiat 500 Keys Industry
Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends the signal to your vehicle to unlock the doors or start the engine. The fob could stop working due to a variety reasons.

A dead battery for the coin is the most common reason for the malfunction of a key fob. Other causes are water damage or a malfunctioning module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob has died. Use a new button cell battery with the same voltage, size and specifications like the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must 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 to water, but still does not work, there may be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan can aid in these situations.

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's possible to repair it by taking out the batteries and cleaning the circuit board with ruby alcohol. It's best to allow the device to completely dry prior to installing batteries.

If your key fob has stopped working, even after replacing the battery and reconfiguring it, you may have a problem with the receiver module. You can find information on reprograming the majority of remote keys on YouTube or consult your owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has the chip that communicates 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 well as water exposure. If the key fob has stopped functioning after exposure to water, it is possible to fix it by cleaning the chip using isopropyl ethanol or electronic cleaner.

If the key fob continues to not respond following cleaning, there is a good chance that the module is faulty and must be replaced. fiat 500 key replacement cost damaged receiver module may also cause the remote control key to stop working. This is usually due to electromagnetic interference.

A defective electronic chip

The electronic chip that is in your key fob is a vital role in the anti-theft security system of your vehicle. It sends a signal to the immobiliser unit inside your car to determine whether or not the key is in fact valid. If the chip is damaged or damaged, your car will not start.

A faulty chip can also be caused by interference signals from other objects like bad weather conditions or transmitters operating on the same frequency near your car. In this situation you'll require an entirely new key fob.

Contacts for the battery that are defective

The battery contacts of the key fob are fragile and are susceptible to damage with hard usage. If they are bent or broken the fob won't send any signals to the receiver modules inside the car.

Modern fobs are constructed with rubber seals that keep out water. A splash of water or light rain should be fine but submerging them into salt water could damage the electronic chip.

The key fob has a chip that communicates with the vehicle's immobilizer system to begin it. The system utilizes the old red keys in older vehicles or the crypto coding system in the latest vehicles. If the chip is defective it must be replaced.

Faulty 12 Volt Battery

A damaged battery could cause the key fob to work. The car's computer may not recognize the remote when this occurs.

Before replacing the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly then it's time to replace the battery.

To test the battery's power to determine its capacity, put an electric load on it for a couple of minutes. This will eliminate about 1 percent of the surface charge. Then, you can measure the voltage once more. The higher the capacity of the battery and the longer it can maintain its voltage. 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 keys not sending signals to cars. The battery could be replaced to fix this problem. However, it is important to purchase a battery that is the same size and voltage as the original.

Fobs take a lot of abuse, and they aren't indestructible. Contacts on batteries and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency may also disrupt the signal. For instance, a light control panel near your home may transmit interference on the same bandwidth that key fobs use. This can affect the remote control of your car.

Faulty OBDII Scan Tool

There are a variety of reasons why a scanner tool may not work. Certain are more complicated than others.

Professional scan tools allow mechanics to monitor the car's network and run a range of self-tests. These tools can save time, but are costly and are out of reach for the majority of 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, it's likely that a fuse has been blown. This is one of the most common causes of scan tool failure. The most straightforward fix is to replace the fuse which has blown.
