fiat 500x key fob replacement fiat panda key programming Key Fob replacement key for fiat ducato van

fiat panda remote Key replacement Panda key fobs contain a transponder chip which sends an alert to your car to open the doors or start the engine. However, the fob may stop working for several reasons.

The most common cause of key fob failure is a dead coin battery. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

Replace the battery in case your key fob is dead. Choose a button battery with the same voltage, size and specifications as your previous one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. The best method is to use the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob doesn't working despite not being exposed to water, it could be due to a glitch in the receiver module or in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan may assist in these situations.

Water Damage

If your key fob has taken an immersion in the puddle or pool or even a trip down the washing machine, you could be suffering some water damage. It's usually possible to get it back in working order by removing the batteries and cleaning the circuit board using rubbing alcohol. It's a good idea to let the fob dry completely prior to installing a new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or updating. You can find the instructions for reprogramming most vehicles' remote keys on YouTube or in the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that connects to the fiat 500 car key's system. This chip will stop sending and receiving signals to the car if it becomes damaged. A key fob falling off can cause this, as could exposure to water. If the key fob stopped working after exposure to water, it could be possible to fix the issue by cleaning the chip with isopropyl alcohol or an electronic cleaner.

However, if the key fob is still unable to not respond after cleaning it, then it is likely that the component is damaged and will need to be replaced. A damaged receiver can cause the key to cease to function. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob plays an important role in the anti-theft security system in your car. It sends out a signal the immobiliser unit in your vehicle to tell it whether or not the key is legitimate. If the chip is damaged or broken, your vehicle will not start.

A faulty chip can also be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency near your vehicle. In this situation you'll require an entirely new key fob.

Faulty Battery Contacts

The battery contacts on the fob's key can be damaged by excessive usage. If they are bent or broken the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs come with rubber seals to keep out water. Immersing them in water, even if it's only a light drizzle or splash can harm the chip's electronic circuit.

The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. The system relies on cryptocoding systems in the latest vehicles, or the old red key system used in older models. If the chip is not working properly it will have to be replaced.

A faulty 12 Volt battery

A malfunctioning battery could cause the fiat 500 key fob replacement fob to function. When this occurs the car's computer will not be able to recognize that the remote is in the vehicle.

Before you replace the battery, test it using a a voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading decreases significantly then it's time to replace the battery.

To test a battery's capacity to determine its capacity, put an electric load on it for a couple of minutes. This will remove about 1 percent of the surface charge. Then measure the voltage again. The higher the capacity of the battery is, the longer it will keep its voltage. Ideal is to hold close to 12 volts over several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason for the key fob not sending signals to the car. This issue can be resolved by replacing the battery. It is essential to purchase a battery that has the same voltage and dimensions as the original.

Fobs can take a lot punishment, and aren't indestructible. Battery contacts and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency may also interfere with a signal. A light control panel in your home, for example can interfere with key fobs that have the same bandwidth. This could affect the remote control of your car.

Afflicted OBDII scan tool

There are many reasons a scanner tool may not perform. Some are more complicated than others.

Professional scan tools enable mechanics to look over the car's networks and run various self-tests. These are real time savers but they are also extremely expensive, and beyond the reach of most DIYers.

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine there is a chance that a fuse has ruptured. This is the main reason for failure of the scan tool. The simple fix is usually to replace the fuse which has blown.
