10 Things Your Competitors Inform You About Fiat 500 Keys

Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car that allows it to unlock doors or start the motor. However, the fob may not function due to a variety of reasons.

A dead battery for the coin is the most frequent reason for malfunctioning keys. Other causes are water damage or a damaged module and interference signals.

Dead Coin Battery

If the battery in your key fob is dead, the first step is to replace it. Use a brand new button battery that has the same size, voltage, and specification as the original.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will work wonders.

If the key fob isn't working even though it is not exposed to water it could be due to a glitch in the receiver module, or even in the internal electronic chip. In these instances it is possible to re-programme the key fob with an OBDII scanner could assist.

Water Damage

If your key fob has taken an immersion in the puddle or pool, or taken a trip to the washing machine, you may have some water damage. You can usually restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea allow the fob to dry completely before putting in a brand new battery.

If your key fob stopped working, even after replacing the battery and changing the program, you could have a defective receiver module. You can find the instructions for the reprogramming of most remote keys on YouTube or in your owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it will be unable to longer transmit or receive signals to the vehicle. Dropping the key fob can cause this, as could exposure to water. If your key fob isn't working due to exposure to water and you are unable to fix it if you clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob doesn't respond to cleaning, it is possible that the receiver module has an issue and must be replaced. A defective receiver module could also cause the remote control key to not function. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential element of the anti-theft device in your vehicle. It sends a signal to the immobiliser in your car to inform it that the key is valid. If the chip is damaged or damaged, your car will not start.

A damaged chip could be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this instance you'll require an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts in a key fob are very delicate and may be damaged by repeated use. If they're bent or broken the fob won't send any signals to the receiver modules in the car.

Modern fobs come with rubber seals to keep out water. Submerging them in water even if it's just small splash or drizzle could harm the chip's electronic components.

The key fob contains the chip that connects to the vehicle's immobilizer system in order to activate it. This system makes use of cryptocoding systems in the latest vehicles as well as the traditional red key system used in older ones. This chip will need to be replaced if it's defective.

A faulty 12 Volt battery

A faulty battery may cause the key fob not to work. The car's computer may not recognize the remote if this happens.

Before replacing the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If  fiat 500 car key  falls significantly, it's time to replace it.

To test a battery's capacity test the battery's capacity by placing an electrical load on it for a few minutes. This will take away approximately 1% of the charge on the surface. Then, test the voltage again. The greater the battery's capacity is, the longer it will keep its voltage. Ideal is to hold at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for a keyfob that stops sending signals to the car. The issue can be fixed by replacing the battery. It is essential to purchase a battery with the same voltage and dimensions as the original.


Fobs take a lot of abuse, and they aren't impervious to destruction. The battery buttons and contacts are brittle, so they can get bent or damaged by excessive use.

A signal may also be interrupted by other transmitters or objects which use the same frequency. For instance, a lighting control panel that is near your home could transmit interference using the same frequency as key fobs utilize. This could interfere with your car's remote control.

Faulty OBDII scan tool

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

Professional scan tools allow mechanics to observe the car's networks and run a range of self-tests. These are great time-savers, but they can be expensive, out of the budget of many DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's likely that a fuse has blown. This is the main reason for failure of the scan tool. It is typically easy to fix the issue by replacing the blown fuse.
