fiat key fob not working Panda Key Fob fiat 500 replacement remote key cost (Harrison-Daniels.Federatedjournals.Com)

fiat ducato key fob programming Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car that allows it to unlock doors or start the motor. The fob can stop functioning due to a variety of reasons.

A dead battery for the coin is the most common cause of malfunctioning keys. Other reasons include water damage, a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery if your key fob is dead. Make use of a new button battery that has exactly the same size, voltage, and specification like the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before using again. A paper towel soaked in isopropyl alcohol or electronic cleaner can do the trick.

If the key fob is not 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 by using an OBDII scan may aid in these situations.

Water Damage

If your key fob has taken submerged in a puddle or pool or walked down the washing machine, you might have some water damage. It is usually possible to repair it by taking out the batteries and cleaning the circuit board using rubbing alcohol. It's best to let the circuit board completely dry prior to installing the battery.

It could be that you have a defective module in the event that your remote stops working after replacing the battery or changing the programming. You can find the instructions for reprograming the majority of remote keys on YouTube or refer to the owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that connects to the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. The key fob being dropped can cause this, as could water exposure. If the key fob you have purchased has stopped working due to water exposure and you are unable fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob still does not respond after cleaning it then it is likely that the module is defective and must be replaced. A damaged receiver can cause the key to stop working. This is typically caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside the key fob is an essential component of the anti-theft systems in your car. It sends a signal to the immobiliser unit in your car to inform it whether the key is legitimate. Your car will not start if the chip is damaged.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this scenario an upgrade to the fob will be needed.

Contacts of the battery may be damaged.

The battery contacts of the fob's battery can be damaged through heavy use. If they are damaged or bent, the key fob won't send any signals to the receiver modules in the car.

Modern fobs feature rubber seals to keep out water. Submerging them in water, even if just small splash or drizzle can harm the electronic chip.

The key fob comes with chip that communicates with the immobilizer system of the vehicle in order to start it. The system is based on the old red keys that were used in older vehicles, or the cryptocoding system that is used in the latest vehicles. If the chip is defective and needs to be replaced.

The 12 Volt Battery is faulty

A defective battery can cause the remote to cease working. When this occurs, the car's computer system will not be able to recognize that the remote is within the vehicle.

Before you replace the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery will read 12.6 volts. If the reading drops dramatically, it's time to replace it.

Install an electrical charge for a short time on the battery to gauge its capacity. This will eliminate approximately 1% of the surface charge. After that, take the voltage again. The longer a battery can hold its voltage more effectively, the greater its capacity. Ideal is that it stays close to 12 volts during several minutes.

Faulty Radio Signal

This is the main reason for a keyfob that stops sending signals to the car. The battery can be replaced to fix this issue. It is however important to buy a new battery that is the same size and voltage as the original one.

Fobs are not indestructible and can take a lot. The battery buttons and the contacts are fragile, so they can get bent or damaged from the force of.

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 which use the same bandwidth. This could affect your car's remote control.

Faulty OBDII scan tool

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

Professional scan tools enable mechanics to monitor the car's network, and run various self-tests. These tools can help save time, but they are costly and are out of reach for the majority of DIYers.

If your OBD2 scan tool fails to turn on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's possible that a fuse has failed. This is the most common cause of scan tool failure. The easiest solution is to replace the blown fuse.
