The Intermediate Guide In Fiat 500 Keys Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends the signal to your vehicle to open the doors or start the engine. However, the fob can stop working for several reasons.

A dead battery for the coin is the most frequent cause of the malfunction of a key fob. Other causes include water damage, malfunctioning receiver modules 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 that has the same voltage, size and specifications as the previous one.


If the key fob was exposed to water, like a splash of rain or salt water on the beach, it will need to be cleaned before it can be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will be the solution.

If the key fob has not been exposed to water, but isn't working, there may be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan could help in these cases.

Water Damage

There could be water damage if your key fob was submerged in a puddle, pool or washing machine. It's generally possible to fix it by taking the batteries off and cleaning the circuit board using ruby alcohol. It's best to let the board completely dry before installing batteries.

You could have a damaged module in the event that your remote stops working after replacing the battery or updating. You can find reprogramming instructions for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car when it is damaged. This could be due to dropping the key fob or through exposure to water. If the key fob is not functioning after exposure to water, it is possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob does not respond following cleaning, you can be sure that the module is defective and will need to be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob plays a vital part in the anti-theft security system of your car. It transmits a message to the immobiliser in your car that tells it whether the key is legitimate. www.g28carkeys.co.uk won't start in the event that the chip is damaged.

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

Faulty battery contacts

The battery contacts on the key fob could be damaged by heavy usage. If they're broken or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs feature rubber seals that keep out water. A splash of water or a light rain is acceptable but submerging them into saltwater can harm the electronic chip.

The key fob houses an electronic chip that communicates with the vehicle's immobilizer to allow it to begin it. The system relies on cryptocoding systems in the latest vehicles, or the old red key system in older models. If the chip is not working properly it will have to be replaced.

The 12 Volt Battery is faulty

A damaged battery can cause the key fob to stop working. The car's computer will not recognize the remote if this happens.

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

To test a battery's capacity to determine its capacity, put an electric load on it for a few minutes. This will eliminate approximately 1% of the charge on the surface. Then, test the voltage again. The greater the battery's capacity and the longer it can keep its voltage. The ideal scenario is to keep it close to 12 volts 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 the car. This issue can be fixed by replacing the battery. But, it is essential to select a replacement battery with the same voltage and size as the original one.

Fobs endure a lot of abuse, but they're also not indestructible. Battery contacts and buttons can be damaged by rough handling.

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

Afflicted OBDII Scan Tool

There are many reasons why a scan tool might not work. Certain are more complicated than others.

Professional scan tools let mechanics to observe the car's networks and run various self-tests. These tools can save a lot of time, but are costly and out of reach for the majority of DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present the chances are that a fuse has been blown. This is the main cause of scan tool failure. It is often easy to fix the issue by replacing the fuse blowing up.
