Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder which transmits a signal from the fob to the car that allows it to unlock doors or turn on the motor. The fob can stop functioning due to a variety reasons.

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

Dead Coin Battery

Replace the battery if the key fob has gone out of service. Use a button cell battery that has the same voltage, size, and specifications as the old one.

If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. The trick is to use the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob doesn't working despite not being exposed water it could be due to a problem in the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan could aid in these situations.

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's generally possible to get it back in working order by taking out the batteries and cleaning the circuit board using rubbing alcohol. It is best to let the board completely dry before installing the battery.

You may have a faulty module if your key fob stops working after replacing the battery or replacing it with. You can find instructions for reprogramming most vehicles' remote keys on YouTube or in the owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip that connects to the car's system. The chip will stop sending and receiving signals to the car when it is damaged. The key fob being dropped can cause this, as well as water exposure. If your key fob has stopped functioning due to water exposure or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob won't respond to cleaning, it is likely that the module is in a fault and needs to be replaced. A faulty receiver module can also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference.

A malfunctioning electronic chip

The chip that is embedded in the key fob is a vital component of the anti-theft systems in your vehicle. It transmits a signal to the immobiliser device in your vehicle to tell it whether or not the key is genuine. Your car will not start when the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency as your car. In this case, you will need an entirely new key fob.

Contacts with the battery may be damaged.





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

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

The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle, allowing it to start it. It uses the old red keys in older vehicles or the crypto coding system in modern vehicles. This chip will need to be replaced if it's defective.

Poor 12 Volt Battery

A damaged battery could cause the key fob not to work. The car's computer will not recognize the remote when this occurs.

Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading drops significantly, it's time to replace it.

Set an electrical load for a few seconds on the battery to check its capacity. This will take away 1percent of the charges. Then measure the voltage again. The greater the battery's capacity is, the longer it will keep its voltage. Ideal is to hold close to 12 volts during several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason behind a key fob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is crucial to buy an identical battery voltage and dimensions as the original.

Fobs aren't impervious to damage and are susceptible to damage. Contacts on batteries and buttons can be damaged through rough handling.

fiat keys can also be affected by other objects or transmitters that use the same frequency. A light-control system in your home, for instance, may interfere with key fobs that have the same frequency. This could interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons why scanner tools may not perform. Certain are more complicated than others.

Professional scan tools let mechanics to monitor the car's networks and run various self-tests. These tools can save you a lot of time, but they're expensive and not accessible to most DIYers.

If your OBD2 scan tool won't power on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse has been blown. This is among the most frequent causes of a scan tool failing. The easiest solution is to replace the fuse which has blown.
