Get Rid Of Fiat 500 Keys: 10 Reasons Why You No Longer Need It

Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends signals to your car to open the doors and start the engine. However, the key fob may not function due to a variety of reasons.

A dead battery for the coin is the most frequent reason for key fob malfunctions. Other causes are water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

If the battery in your key fob has gone out of service, the first step is to replace it. Choose a button battery with the same voltage, size, and specifications 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 best solution is to use an old towel soaked in isopropyl, or electronic cleaner.

If the key fob has not been exposed to water but remains inoperable, there may be a problem with the receiver module or an internal electronic chip. In these instances, reprogramming the key fob using an OBDII scanner can assist.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. You can usually restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It's best to let the board completely dry before installing batteries.


You may have a faulty module when your key fob ceases working after replacing the battery or updating. Reprogramming instructions are available for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with the chip that communicates the vehicle's system. If the chip is damaged, it cannot longer transmit or receive signals to the vehicle. Dropping the key fob can result in this, as can water exposure. If your key fob stopped functioning due to exposure to water, you may be able fix the issue if you clean the chip using electronic cleaner or isopropylethanol.

However, if the key fob does not respond after cleaning it, then it is likely that the component is damaged and will need to be replaced. A damaged receiver can cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in the key fob is a vital part of the anti-theft system in your car. It transmits a message the immobiliser in your car to tell it whether the key is legitimate. If the chip is damaged or damaged, your car will not start.

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

Contacts with the battery may be damaged.

The battery contacts on a key fob can be damaged through heavy use. If they're bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain is acceptable However, submerging them in saltwater can damage the chip's electronic components.

The key fob contains chips that communicate with the vehicle's immobilizer system in order to allow it to start. This system utilizes cryptocoding systems in modern vehicles, or the old red key system in older models. This chip will have to be replaced if faulty.

The 12 Volt Battery is faulty

A defective battery can cause the key fob to cease working. The car's system will not recognize the remote when this happens.

Before you replace the battery, test it using a a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it is time to replace the battery.

Place an electrical load for a few moments on the battery to test its capacity. This will eliminate 1percent of the charges. Then, measure the voltage again. The higher the capacity of the battery, the longer it can maintain its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason behind a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. But, it is essential to choose a battery that is the same size and voltage as the original.

The buttons are not impervious to destruction and can withstand a lot. The battery buttons and the contacts are fragile, so they can get bent or damaged by excessive use.

A signal may also be interrupted by other transmitters or objects that use the same frequency. A light-control panel at your home, for example, may interfere with key fobs using the same bandwidth. This could cause interference with the remote control of your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scan tool could not work. replacement fiat 500 key are more complex than others.

Professional scan tools enable a mechanic observe the car's networks and run various self-tests. These can be real time savers, but they are also extremely expensive, out of the budget of many DIYers.

If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse is blowing. This is one of the most common causes of a scan tool failing. It is typically simple to fix the issue by replacing the blown fuse.
