10 Things That Your Competitors Inform You About Fiat 500 Keys
Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car in order to unlock doors or turn on the motor. The fob may stop working for a variety.

The most common cause of key fob malfunction is the battery of the coin is dead. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

Replace the battery if your key fob is dead. Use a button cell with the same voltage, size and specifications as the previous one.

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

If the key fob is not working despite not being exposed water, it could be due to a malfunction in the receiver module or an internal electronic chip. In these instances, reprogramming the key fob with an OBDII scanner can assist.

Water Damage

If your key fob took an immersion in the puddle or pool, or taken a trip down the wash machine, it could have some water damage. It's generally possible to get it working by getting rid of the batteries and cleaning the circuit board using ruby alcohol. It's best to allow the device to completely dry before installing the battery.

If your key fob has stopped working, even after replacing the battery and programming it again, you might have a faulty receiver module. You can find information on reprogramming most vehicles' remote keys on YouTube or refer to 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 contains a chip that communicates with the vehicle's system. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or by water exposure. If the key fob is not working after exposure to water it could be possible to fix it by cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob continues to not respond after cleaning it, you can be sure that the receiver module is not functioning properly and will require to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Faulty electronic chip

The electronic chip that is in your key fob plays a vital part in the anti-theft security system in your car. It transmits a message to the immobiliser inside your car to tell it if the key is valid. The car will not start if the chip is damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters near your vehicle. In this situation you'll require an entirely new key fob.

Contacts of the battery may be damaged.

The battery contacts in a key fob are very delicate and may be damaged through repeated use. If they are damaged or bent, the key fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals in order to keep out water. A splash of water or light rain is fine however, submerging them in saltwater could cause damage to the electronic chip.

The key fob is equipped with the chip that connects to the vehicle's immobilizer system to begin it. This system utilizes cryptocoding systems in vehicles that are more modern and the older red key system in older models. The chip must be changed if it is damaged.


Faulty 12 Volt Battery

A faulty battery can cause the remote to stop working. When this happens, the car's computer system cannot recognize that the remote is in the vehicle.

Before you replace the battery, test it using a the voltmeter to determine its capacity. spare key for fiat 500 charged battery will read 12.6 volts. If the reading falls significantly, it is time to replace the battery.

To test a battery's capacity put an electrical load on it for a few minutes. This will remove one percent of the surface charges. Then, you can measure the voltage. The greater the battery's capacity is, the longer it will maintain its voltage. Ideal is that it stays at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the main cause of a key fob that stops sending signals to the car. The battery could be replaced to fix this problem. However, it is important to purchase a battery with the same size and voltage as the original one.

Fobs are not indestructible and are susceptible to damage. The battery contacts and buttons are delicate and can be bent or broken with rough use.

Other transmitters or objects that use the same frequency could also interfere with the signal. A light-control panel at your home, for example can interfere with key fobs which use the same bandwidth. This could interfere with the remote control of your car.

Incorrect OBDII Scan Tool

There are many reasons a scanner tool may not work. Some are more complex than others.

Professional scan tools allow a mechanic to monitor the car's network and perform a variety of self-tests. These can be real time savers but they're also expensive, and out of the range of most DIYers.

If your OBD2 scan tool isn't turning on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's possible that a fuse has blown. This is among the most common causes of failures in the scan tool. It is usually simple to fix the issue by replacing the fuse that has blown.
