fiat 124 spider key fob cover Panda Key Fob replacement fiat 500 key fob

fiat remote key Panda key fobs contain a transponder chip that sends the signal to your vehicle to open the doors or start the engine. The fob can stop functioning due to a variety of reasons.

A dead coin battery is the most common cause of malfunctioning keys. Other causes include water damage an inoperative receiver module and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has failed. Make use of a new button battery that is the same voltage, size and specifications as the previous one.

If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it needs to be cleaned before it is able to be used again. The best solution is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob is not working even though it is not exposed to water, it could be due to a problem in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan could help in these instances.

Water Damage

There could be water damage if your key fob was submerged in a puddle, pool or washing machine. You can usually get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is a good idea to let the fob dry completely before putting in a new battery.

If your fiat bravo key fob has stopped working, even after replacing the battery and reprogramming it, you may have a faulty receiver module. There are instructions for reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with an electronic chip that communicates with the car's system. If this chip becomes damaged, it can no longer transmit or receive signals to the vehicle. This could be due to dropping the key fob or due to exposure to water. If the key fob stops working after exposure to water it could be possible to repair the issue by cleaning or cleaning the chip with isopropyl ethanol or electronic cleaner.

If the key fob won't respond to cleaning, it's possible that the component has an issue and must be replaced. A damaged receiver can cause the key to cease to function. This is typically caused by electromagnetic interference.

A defective electronic chip

The electronic chip in the key fob is an important component of the anti-theft system in your vehicle. It sends out a signal the immobiliser unit of your car to inform it whether the key is in fact valid. If the chip is damaged or broken, the car will not start.

A damaged chip could be caused by interference signals from objects like bad weather conditions or transmitters operating on the same frequency as your vehicle. In this instance, a new fob will be needed.

Contacts to the battery are not working properly.

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

Modern fobs are equipped with rubber seals that keep out water. A splash of water or light rain should be fine however, submerging them in saltwater can cause damage to the electronic chip.

The key fob contains an electronic chip that communicates with the immobilizer system of the vehicle, allowing it to start it. This system uses crypto coding systems in newer vehicles as well as the traditional red key system in older ones. If the chip is defective it must be replaced.

A faulty 12 Volt battery

A defective battery can cause the key fob to stop working. If this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

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

To determine the capacity of a battery test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away approximately 1% of the charge on the surface. Then take another measurement of the voltage. The greater the battery's capacity is, the longer it will maintain its voltage. Ideally, it will remain at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the main cause of a key fob that stops sending signals to the car. This issue can be fixed by replacing the battery. It is crucial to purchase a battery with the same voltage and dimensions as the original.

Fobs are subject to a lot of abuse, but they're not impervious to destruction. The battery buttons and the contacts are fragile, so they can get bent or damaged by rough use.

The signal could also be disrupted by other transmitters or objects that use the same frequency. A light-control panel in your home, for example, may interfere with key fobs using the same frequency. This could cause interference with your car's remote control.

Afflicted OBDII scan tool

There are many reasons why a scan tool could not function. Some are more complicated than others.

Professional scan tools let mechanics to monitor the car's network and perform various self-tests. These tools can save you a lot of time, but they are costly and out of reach for most DIYers.

If your OBD2 scan tool fails to turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present the chances are that a fuse has been blown. This is the most typical cause of scan tool failure. The easiest fix is to replace the fuse that has been blown.
