Why We Our Love For Fiat 500 Keys (And You Should Also!)
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car to unlock doors or turn on the motor. The fob can stop functioning for a variety.
The most common cause of key fob failure is an inoperable coin battery. Other causes are water damage or a damaged module and interference signals.
Dead Coin Battery
If your key fob battery has gone out of service, the first step is to replace it. Use a brand new button battery that is exactly the same size, voltage and specification as the original.
If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned before being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will work wonders.
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 even in the internal electronic chip. In these instances you can reprogramme the key fob with an OBDII scanner could assist.
Water Damage
If your key fob has taken submerged in a puddle or pool or gone to the washing machine, you could be suffering some water damage. It's possible to repair it by taking out the batteries and cleaning the circuit board using rubbing alcohol. It is a good idea to let the fob dry completely prior to installing a new battery.
If your key fob isn't working even after replacing the battery and programming it again, you might have a malfunctioning receiver module. There are instructions for reprograming the majority of remote keys on YouTube or refer to your owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is a chip which communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob or due to exposure to water. If the key fob you have purchased has stopped working due to water exposure or water exposure, you might be able to fix it if clean the chip using electronic cleaner or isopropyl alcohol.
If the key fob does not respond after cleaning it it is likely that the module is faulty and must be replaced. TheKeyLab can cause the key to not work. This is usually caused by electromagnetic interference.
A malfunctioning electronic chip
The electronic chip in your key fob is a vital role in the anti-theft security system in your car. It sends out a signal the immobiliser unit inside your vehicle to tell it whether the key is in fact valid. The car will not start when the chip is damaged.
A defective chip could be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this instance 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're damaged or bent, the key fob will not be able to send any signals to the receiver modules in the car.
Modern fobs are constructed with rubber seals to keep out water. A splash of water or a light rain should be fine, but submerging them in saltwater can harm the chip's electronic components.
The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle to begin it. The system utilizes the old red keys in older vehicles, or the cryptocoding system that is used in newer vehicles. If the chip is not working properly, it will need to be replaced.
The 12 Volt Battery is faulty
A faulty battery can cause the key fob to cease to function. The car's computer will not recognize the remote when this happens.
Before replacing the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery will read 12.6 volts. If the reading decreases significantly the time is now to replace it.
Put an electrical load for a short time on the battery to test its capacity. This will remove 1% of the surface charges. After that, take the voltage once more. The longer the battery is able to keep its voltage steady greater is its capacity. Ideally, it should remain close to 12 volts for several minutes.
Faulty Radio Signal
This is the most frequent cause of a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this problem. It is however important to purchase a battery with the same voltage and size as the original one.
Fobs are not indestructible and are susceptible to damage. Contacts on batteries and buttons can be damaged through rough handling.
The signal could also be interrupted by other transmitters or objects that operate on the same frequency. For instance, a light-control panel that is near your home could send interference on the same frequency as key fobs use. This can interfere with the remote control in your car.
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 permit mechanics to examine the car's systems and perform a variety of self-tests. These tools can save a lot of time, but they are costly and out of reach for the majority of DIYers.
If your OBD2 scan tool doesn't turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's likely that a fuse has failed. This is among the most frequent causes of scan tool failure. The most straightforward fix is to replace the fuse that is blowing up.
