Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car to open doors or start the motor. However, the key fob may stop working due to a variety of causes.

A dead coin battery is the most frequent reason for key fob malfunctions. Other causes include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

Replace the battery if your key fob has failed. Choose a button battery that has the same voltage, size and specifications as your previous one.

If the key fob was exposed to water, such as a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will be the solution.

If the key fob has not been exposed to water but still does not work, there may be a problem with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner could aid.

Water Damage

There could be water damage to your key fob if it was submerged in a pool, puddle or washing machine. It is usually possible to repair it by taking out the batteries and cleaning the circuit board using ruby alcohol. It is best to let the circuit board completely dry prior to installing batteries.

You may have a faulty module in the event that your key fob stops working after replacing the battery or replacing it with. There are instructions for changing the programming of most remote keys on YouTube or in the owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob or by water exposure. If your key fob stopped functioning due to water exposure and you are unable to fix it if clean the chip with electronic cleaner or isopropylethanol.

If the key fob won't respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A faulty receiver can also cause the key to cease to function. This is usually caused by electromagnetic interference.

A defective electronic chip

The electronic chip that is in your key fob plays a crucial role in the anti-theft security system in your car. It sends a signal to the immobiliser unit inside the vehicle to determine whether the key is valid. The car will not start if the chip is damaged.





A malfunctioning chip can be caused by interference from other objects, weather conditions or transmitters close to your vehicle. In this case you'll require an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts on the key fob are delicate and may be damaged when used for long periods of time. If they're broken or bent, the fob will not send any signals to the receiver modules inside the car.

Modern fobs have rubber seals to keep out water. Submerging them in water, even if just the slightest splash or drizzle could damage the chip's electronic components.

The key fob has an electronic chip that communicates with the vehicle's immobilizer system to activate it. This system utilizes cryptocoding systems in modern vehicles or the red key system in older models. The chip must be replaced if defective.

Problematic 12 Volt Battery

A faulty battery can cause the remote to cease to function. The car's computer will not recognize the remote when this occurs.

Before replacement key fiat 500 replace the battery, test it with a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.

To test the battery's power, place an electrical load on it for a few minutes. This will remove approximately 1% of the charge on the surface. Then, measure the voltage again. The longer a battery is able to keep its voltage steady more effectively, the greater its capacity. The ideal is to keep it at or near 12 volts for several minutes.

Problems with Radio Signal

This is the main reason for the key fob to stop sending signals to the car. The battery can be replaced to fix this problem. It is important to buy a battery with the same dimensions and voltage as the original.

Fobs take a lot of abuse, but they're also not impervious to destruction. Contacts and buttons on batteries can be damaged through rough handling.

A signal can also be disrupted by other objects or transmitters which use the same frequency. For instance, a lighting control panel close to your home can transmit interference on the same bandwidth that key fobs utilize. This could interfere with the remote control of your car.

The tool is not working properly. OBDII scan tool

There are many reasons why a scan tool might not work. Some are more complex than others.

Professional scan tools enable mechanics to observe the car's networks and run a variety of self-tests. These are great time savers, however they are also extremely expensive, and beyond the reach of most DIYers.

If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's possible that a fuse has blown. This is the most common reason for a scan tool to fail. The easiest solution is to replace the fuse that is blowing up.
