fiat 500x key Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends an alert to your car to unlock the doors or start the engine. However, the fob could stop working for several reasons.

A dead battery for the coin is the most common cause of a key fob malfunction. Other causes are water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Use a button cell battery that has the same voltage, size and specifications as your previous one.

If the fiat 500x key fob programming fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned before using again. The trick is to use the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water, but isn't working, there may be an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob using an OBDII scanner can aid.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It's 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 fob to dry completely before putting in a brand new battery.

If your key fob isn't 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 consult the owner's manual. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the car's system. If this chip becomes damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or through exposure to water. If your key fob has stopped working due to water exposure, you may be able fix the issue if you clean the chip using electronic cleaner or isopropylethanol.

If the key fob does not respond to cleaning, it is possible that the component has a fault and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is an important component of the anti-theft system in your car. It sends a signal to the immobiliser in your car to tell it whether the key is genuine. The car won't start if the chip is damaged.

A faulty chip may also be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this scenario the replacement fob will be needed.

Faulty Battery Contacts

The battery contacts on the fob's key can be damaged by excessive usage. If they are bent, or damaged, the fob will not send any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals that block out water. Submerging them in water, even if just an occasional drizzle or splash can harm the chip's electronic circuit.

The key fob houses an electronic chip that communicates with the vehicle's immobilizer to allow it to activate it. The system is based on the old red keys in older vehicles as well as the cryptocoding system used in newer cars. If the chip is damaged it will have to be replaced.

Faulty 12 Volt Battery

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

Before you replace the battery, you should test it with a the voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly, it's time to replace it.

To test the battery's capacity put an electrical load on it for a few minutes. This will take away one percent of the surface charges. Then, you can measure the voltage again. The greater the battery's capacity and the longer it can maintain its voltage. It is ideal to maintain close to 12 volts during several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for a key fob that stops sending signals to the car. This issue can be resolved by replacing the battery. It is essential to purchase a battery that has the same voltage and dimensions as the original.

The buttons are not impervious to destruction and can withstand a lot. Battery contacts and buttons can be damaged through rough handling.

A signal can also be affected by other transmitters or objects which use the same frequency. A light-control panel in your home, for Fiat Panda key example can interfere with key fobs that use the same bandwidth. This could interfere with the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons a scanner tool may not function. Certain are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network and perform a variety of self-tests. These tools can help save time, but they're expensive and not accessible to the majority of DIYers.

If your OBD2 scan tool fails to turn on, test the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're all fine, a fuse may have blown. This is one of the most common causes of failures in the scan tool. It is often easy to fix the issue by replacing the fuse that has blown.
