fiat 500 key fob not working Panda Key Fob Replacement

Fiat Abarth Key Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car in order to unlock doors or turn on the motor. The fob can stop functioning due to a variety of reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes include water damage, the receiver module is defective and signal interference.

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or Fiat Abarth Key saltwater at the beach) it must be cleaned prior Fiat abarth key to being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.

If the key fob is not working despite being not exposed to water it could be due to a glitch in the receiver module, or even in the internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner could help.

Water Damage

If your key fob has gotten immersed in a pool or puddle or walked to the washing machine, you could be suffering some water damage. It's usually possible to restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the circuit board completely dry before putting in a battery.

If your key fob has stopped working even after replacing the battery and changing the program, you could have a defective receiver module. There are instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also reset your computer of your car using 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 or receive signals to the vehicle. Dropping the key fob can cause this, as could water exposure. If the key fob is not working after water exposure it is possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob doesn't respond to cleaning, it's likely that the module is in an issue and must be replaced. A malfunctioning receiver could cause the key to cease to function. This is usually due to electromagnetic interference.

Faulty Electronic Chip

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

A damaged chip could be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this instance it is likely that a new fob would be needed.

Faulty battery contacts

The battery contacts inside a key fob are very delicate and could be damaged with hard usage. If they're bent or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals to keep out water. In the event of submerging them in water, even if just a light drizzle or splash could harm the chip's electronic circuit.

The key fob houses a chip that communicates with the vehicle's immobilizer system in order to activate it. The system utilizes the red keys of older vehicles or the cryptocoding system that is used in newer cars. This chip needs to be replaced if it's defective.

Faulty 12 Volt Battery

A faulty battery may cause the key fob not to function. When this happens, the car's computer system will not recognize that the remote is in the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly, it is time to replace the battery.

Put an electrical load for a few seconds on the battery to gauge its capacity. This will eliminate 1percent of the surface charges. After that, measure the voltage. The longer a battery can keep its voltage steady greater is its capacity. It should be at 12 volts or less for several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason for the key fob to stop sending signals to vehicles. The battery can be replaced to fix this issue. But, it is essential to choose a battery that is the same voltage and size as the original.

Fobs take a lot of punishment, and aren't impervious to destruction. The battery buttons and contacts are delicate and can be bent or broken with rough usage.

The signal could also be affected by other transmitters or objects that operate on the same frequency. For instance, a lighting control panel near your home may transmit interference using the same frequency as key fobs use. This can affect the remote control of your car.

Afflicted OBDII Scan Tool

There are many reasons why a scan tool could not function. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's networks and run a variety of self-tests. These tools can help save time, but they're expensive and not accessible to most DIYers.

If your OBD2 scan tool won't power on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK it could be that a fuse has failed. This is the most typical reason for a scan tool to fail. It is generally easy to fix the problem by replacing the fuse that has blown.
