This Is The Intermediate Guide To Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat 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 can be inoperable due to various reasons.
The most common reason for key fob malfunction is a dead coin battery. Other reasons include water damage, a faulty receiver module and signal interference.
Dead Coin Battery
Replace the battery if the key fob has gone out of service. Make use of a new button battery that is the same size, voltage and specifications like the previous one.
If the key fob was exposed to water, like a splash of rain or salt water on the beach, it needs to be cleaned before it can be used again. The best solution is to use the paper towel and soak it in isopropyl or electronic cleaner.
If the key fob has not been exposed to water but it is still not working it could be because of a problem with the receiver module or an internal electronic chip. In these situations it is possible to re-programme the key fob using an OBDII scanner can assist.
Water Damage
You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the device to completely dry before putting in batteries.
There could be a problem with the module in the event that your remote stops working after replacing the battery or changing the programming. You can find the instructions for the reprogramming of most remote keys on YouTube or consult the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob has a chip that communicates with the car'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 your key fob isn't functioning due to water exposure it is possible to fix it if you clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob doesn't respond to cleaning, it's possible that the component has issues and needs to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This usually happens due to electromagnetic interference.
Electronic chip that is malfunctioning
The electronic chip inside your key fob plays a crucial role in the anti-theft system of your vehicle. It sends a message to the immobiliser inside your car to inform it whether the key is legitimate. Your car won't start in the event that the chip is damaged.
A faulty chip may also be caused by interference from objects, bad weather or transmitters near your vehicle. In this situation you'll need an entirely new key fob.
Contacts to the battery are not working properly.
The battery contacts on the fob's battery can be damaged by heavy usage. If they are bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.
Modern fobs are constructed with rubber seals in order to keep out water. A splash of water or light rain is fine, but submerging them in saltwater could damage the chip's electronic components.
The key fob houses chips that communicate with the vehicle's immobilizer system to activate it. It uses the old red keys in older vehicles, or the crypto coding system in modern vehicles. If the chip is damaged it will have to be replaced.
The 12 Volt Battery is faulty
A malfunctioning battery could cause the key fob not to function. The car's computer will not recognize the remote if this occurs.
Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls dramatically, it is time to replace the battery.
To test the battery's power, place an electrical load on it for a couple of minutes. This will take away about 1% of the surface charge. After that, take the voltage again. The longer the battery can hold its voltage and the higher its capacity. The ideal is to keep it close to 12 volts over several minutes.
Radio Signal Faulty Radio Signal
This is the most typical reason for a keyfob that stops sending signals to the car. The issue can be fixed by replacing the battery. It is crucial to buy an identical battery voltage and dimensions as the original.
Fobs endure a lot of abuse, and they aren't impervious to destruction. Battery contacts and buttons can be damaged by rough handling.
Other transmitters or objects using the same frequency can also interfere with the signal. A light-control system in your home, for instance can interfere with key fobs using the same frequency. This can interfere with the remote control of your car.
Incorrect OBDII Scan Tool
There are many reasons why a scan tool might not work. Some are more complicated than others.
Professional scan tools enable a mechanic observe the car's network and perform various self-tests. These can be real time savers, but they are also extremely expensive and are out of the budget of many DIYers.
If your OBD2 scan tool isn't turning on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If fiat key cover are in good condition the chances are that a fuse has failed. This is the main cause of scan tool failure. The most straightforward fix is to replace the fuse which has blown.
