The Three Greatest Moments In Fiat 500 Keys History

Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that sends an electronic signal from the fob to the car in order to unlock doors or turn on the motor. The fob can stop functioning due to a variety reasons.

The most common cause of key fob malfunction is an inoperable coin battery. Other causes include water damages as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if the key fob has died. Use a button cell with the same voltage, size and specifications as your previous one.

If the key fob has been 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 in isopropyl alcohol or electronic cleaner will help.

If the key fob is not working despite not being exposed water, it could be due to a malfunction in the receiver module or internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner can help.

Water Damage

If your key fob took an immersion in the puddle or pool or gone down the washing machine, it could have some water damage. It's usually possible to get it working by taking out the batteries and cleaning the circuit board with ruby alcohol. It is a good idea to let the fob dry completely before installing a new battery.

If your key fob has stopped working, even after replacing the battery and reprogramming it, you may have a malfunctioning receiver module. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. The key fob being dropped can cause this, as could exposure to water. If the key fob has stopped working after exposure to water, it may be possible to repair the issue by cleaning or cleaning the chip using isopropyl ethanol or electronic cleaner.

If the key fob is still unable to not respond following cleaning, then it is likely that the component is damaged and will need to be replaced. A defective receiver module could also cause the remote control key to not function.  replacement fiat key fob  is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob is an essential part of the anti-theft system in your car. It sends a signal the immobiliser device in your car to determine whether or not the key is in fact valid. The car will not start if the chip is damaged.

A defective chip can be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency near your car. In this scenario, you will need an entirely new key fob.

Faulty Battery Contacts

The battery contacts in a key fob are very delicate and can get damaged by repeated use. If they're bent or damaged, the fob will not send any signals to the receiver modules in the vehicle.

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

The key fob has chip that communicates with the immobilizer system of the vehicle to start it. The system is based on the old red keys that were used in older vehicles or the cryptocoding system found in modern vehicles. If the chip is defective, it will need to be replaced.

A faulty 12 Volt battery

A malfunctioning battery could cause the key fob to stop working. The car's computer may not recognize the remote when this happens.


Before replacing the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly, it is time to replace the battery.

Put 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 greater the battery's capacity is, the longer it will maintain its voltage. 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 not sending signals to vehicles. The battery could be replaced to fix this issue. It is important to buy batteries that have the same voltage and dimensions as the original.

Fobs endure a lot of abuse, and they aren't impervious to destruction. The battery contacts and buttons could be damaged through rough handling.

Other objects or transmitters using the same frequency could also interfere with a signal. A light-control system in your home, for instance can interfere with key fobs using the same bandwidth. This can interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons why a scanner may not work. Some are more complex than others.

Professional scan tools allow a mechanic to monitor the car's network and run a range of self-tests. These can be real time savers but they can be expensive, out of the reach of most DIYers.

If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's likely that a fuse has failed. This is among the most frequent causes of failures in the scan tool. It is often simple to fix the issue by replacing the blown fuse.
