Fiat Panda Key Fob replacement key for fiat ducato van
fiat 500 key cover Panda key fobs contain a transponder chip which sends an alert to your car to unlock the doors or start the engine. However, the key fob may stop working for several reasons.
The most frequent cause of key fob failure is the battery of the coin is dead. Other reasons include water damage, malfunctioning receiver modules and signal interference.
Dead Coin Battery
If the battery in your key fob has gone out of service, the first step is how to get a new fiat 500 key replace it. 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, like a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. The best way to do this is using the paper towel and soak it in isopropyl, or electronic cleaner.
If the key fob hasn't been exposed to water but remains inoperable it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan may assist in these situations.
Water Damage
If your key fob has taken immersed in a pool or puddle or walked down the washing machine, you may have some water damage. You can usually get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the circuit board completely dry prior to installing batteries.
You could have a damaged module when your key fob ceases working after replacing the battery or changing the programming. Reprogramming instructions are available for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob has an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it can no longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or through exposure to water. If your key fob has stopped working due to exposure to water it is possible fix the issue if you clean the chip with electronic cleaner or isopropyl ethanol.
However, if the key fob continues to not respond even after cleaning it there is a good chance that the module is defective and will require to be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.
Electronic chip that is malfunctioning
The chip that is embedded in your key fob is an essential part of the anti-theft system in your vehicle. It sends a signal the immobiliser unit inside your car to determine whether or not the key is in fact valid. The car will not start when the chip is damaged.
A damaged chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this instance you'll require an entirely new key fob.
Contacts for the battery that are defective
The battery contacts on a key fob can be damaged by heavy usage. If they are broken or bent, the fob will not be able to send any signals to the receiver modules inside the car.
Modern fobs come with rubber seals that keep out water. A splash of water or light rain is acceptable but submerging them into saltwater can harm the electronic chip.
The spare fiat 500 key fob has chips that communicate with the vehicle's immobilizer to allow it to start it. The system uses the red keys of older vehicles as well as the crypto coding system in the latest vehicles. If the chip is damaged it will have to be replaced.
Poor 12 Volt Battery
A defective battery can cause the key fob to cease working. When this happens, the car's computer system cannot recognize that the remote is within the vehicle.
Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly it's time to change it.
Put an electrical load for a short period of time on the battery to test its capacity. This will remove approximately 1% of the surface charge. After that, measure the voltage. The greater the battery's capacity and the longer it can keep its voltage. Ideally, it should remain at or near 12 volts for several minutes.
Faulty Radio Signal
This is the most frequent reason for the key fob to stop sending signals to cars. This problem can be solved by replacing the battery. However, it is crucial to purchase a battery with the same voltage and size as the original one.
Fobs can take a lot abuse, but they're also not impervious to destruction. Battery contacts and buttons can be damaged by rough handling.
A signal can also be disrupted by other transmitters or objects that operate on the same frequency. A light-control panel at your home, for example, may interfere with key fobs that use the same bandwidth. This could affect the remote control of your car.
The tool is not working properly. OBDII scan tool
There are many reasons why a scan tool could not work. 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 help save time, but they're expensive and out of reach for the majority of DIYers.
If your OBD2 scanner won't start make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine, a fuse may have ruptured. This is one of the most common causes of scan tool failure. It is often simple to fix the issue by replacing the blown fuse.
