Fiat 500 Keys: A Simple Definition
fiat car keys Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends a signal to your car to open the doors or start the engine. The fob can stop functioning for a variety.
A dead battery for the coin is the most frequent reason for a key fob malfunction. Other causes include water damage or a malfunctioning module and interference signals.
Dead Coin Battery
If the battery in your key fob has died, the first step is to replace it. Make use of a new button battery that is the same voltage, size and specification as the original.
If the key fob was exposed to water (such as rain or saltwater at the beach) it must be cleaned before using again. The best way to do this is using the paper towel and soak it in isopropyl, or electronic cleaner.
If the key fob has not been exposed to water, but still does not work it could be because of a problem with the receiver module or an internal electronic chip. In these instances you can reprogramme the key fob with an OBDII scanner may help.
Water Damage
If your key fob has gotten immersed in a pool or puddle or even a trip down the wash machine, you could be suffering some water damage. It's usually possible to repair it by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It is a good idea to let the fob dry completely prior to installing a new battery.
It could be that you have a defective module in the event that your key fiat fob stops working after replacing the battery or fiat 500x key not detected replacing it with. You can find instructions for reprogramming most vehicles' remote fiat 500 all keys lost on YouTube or refer to the owner's manual. You can also reset the computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob contains an electronic chip that communicates with the car's system. This chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob could cause this, as could water exposure. If the key fob has stopped functioning after exposure to water, it is possible to fix it by cleaning the chip with isopropyl ethanol or electronic cleaner.
However, if the key fob still does not respond after cleaning it it is likely that the module is faulty and will require to be replaced. A malfunctioning receiver could cause the key to not work. This is typically caused by electromagnetic interference.
Faulty electronic chip
The electronic chip inside your key fob plays an important function in the anti-theft security system of your vehicle. It sends a signal to the immobiliser unit in your car to inform it whether or not the key is valid. If the chip is damaged or broken, your vehicle won't start.
A faulty chip can also be caused by interference signals from objects like bad weather conditions or transmitters operating on the same frequency as your vehicle. In this case, a new fob will be required.
Faulty battery contacts
The battery contacts of the key fob are delicate and could be damaged when used for long periods of time. If they're damaged or bent, the fob will not transmit any signals to the receiver modules in the car.
Modern fobs have rubber seals that keep out water. Immersing them in water, even if it is just a light drizzle or splash could harm the electronic chip.
The key fob has a chip that communicates with the vehicle's immobilizer to allow it to activate it. This system uses crypto coding systems in the latest vehicles or the red key system for older ones. If this chip is faulty and needs to be replaced.
Faulty 12 Volt Battery
A malfunctioning battery could cause the key fob to work. The car's computer will not recognize the fiat punto remote key when this happens.
Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly it's time to change it.
To determine the capacity of a battery put an electrical load on it for a few minutes. This will eliminate one percent of the surface charges. Then measure the voltage again. The greater the battery's capacity is, the longer it will keep its voltage. Ideal is that it stays 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 a car. This issue can be resolved by replacing the battery. However, it is important to purchase a battery that is the same voltage and size as the original.
Fobs take a lot of punishment, and aren't impervious to destruction. Contacts on batteries and buttons can be damaged through rough handling.
Other objects or transmitters using the same frequency may also interfere with the signal. A light-control system in your home, for instance could interfere with key fobs using the same frequency. This can interfere with the remote control of your car.
Problems with OBDII Scan Tool
There are many reasons why scanners don't perform. Certain are more complicated than others.
Professional scan tools allow a mechanic to examine the car's systems and conduct a variety self-tests. These tools can save time, but are expensive and out of reach for the majority of DIYers.
If your OBD2 scan tool doesn't turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it could be that a fuse has failed. This is one of the most common causes of scan tool failure. The most straightforward fix is to replace the blown fuse.
