Check Out: How Fiat 500 Keys Is Taking Over And What Can We Do About It
Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain an transponder chip that transmits signals to your car to open the doors and start the engine. The fob could stop working due to a variety reasons.
The most frequent cause of key fob malfunction is a dead coin battery. Other causes are water damage, an inoperative receiver module and signal interference.
Dead Coin Battery
Replace the battery in case your key fob has died. Make use of a new button battery with exactly the same size, voltage, and specification like the previous one.
If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will need to be cleaned before it can be used again. The trick is to use the paper towel and soak it in isopropyl or an electronic cleaner.
If the key fob isn'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 cases it is possible to re-programme the key fob with an OBDII scanner might aid.
Water Damage
If your key fob has gotten a bath in the pool or puddle, or taken a trip down the washing machine, you could be suffering some water damage. You can usually get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea let the fob dry completely before putting in a new battery.
If your key fob isn't working even after replacing the battery and reprogramming it, you may have a problem with the receiver module. There are instructions for reprogramming most vehicles' remote keys on YouTube or consult the owner's manual. You can also reset the car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob has the chip that communicates with the vehicle's system. If the chip is damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob or by exposure to water. If your key fob stopped working due to water exposure it is possible to fix it if clean the chip using electronic cleaner or isopropylethanol.
However, if the key fob is still unable to not respond even after cleaning it it is likely that the module is faulty and will require to be replaced. A defective receiver module could also cause the remote control key to not function. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The chip inside your key fob plays a crucial part in the anti-theft security system of your vehicle. It sends a signal to the immobiliser in your car to tell it that the key is valid. The car will not start in the event that the chip is damaged.
A defective chip can be caused by interference signals from objects, bad weather conditions or transmitters operating on the same frequency near your vehicle. In this situation you'll need an entirely new key fob.
Contacts for the battery that are damaged
The battery contacts on the fob's key can be damaged by heavy usage. If they are damaged or bent, the key fob will not send any signals to the receiver modules in the car.
Modern fobs feature rubber seals that keep out water. Submerging them in water, even if just an occasional drizzle or splash could harm the chip's electronic components.
The key fob has a chip that communicates with the vehicle's immobilizer to allow it to allow it to start. The system is based on the red keys of older vehicles, or the cryptocoding system found in newer vehicles. If fiat 500 key cover is defective, it will need to be replaced.
The 12 Volt Battery is faulty
A defective battery can cause the key fob to cease to function. When this occurs, the car's computer system cannot recognize that the remote is in the vehicle.
Before you replace the battery, you should test it with a the voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly the time is now to replace it.
Install an electrical charge for a few moments on the battery to test its capacity. This will take away approximately 1 percent of the surface charge. Then measure the voltage again. The longer a battery can keep its voltage steady and the higher its capacity. Ideally, it should remain at 12 volts or less for several minutes.
The radio signal is not working properly. Radio Signal
This is the most typical reason for the key fob not sending signals to the car. This issue can be fixed by replacing the battery. It is essential to purchase an identical battery dimensions and voltage as the original.
Fobs take a lot of abuse, but they're not impervious to destruction. The battery buttons and the contacts are fragile which means they could be bent or damaged by rough usage.
Other objects or transmitters using the same frequency may also interfere with the signal. A light-control system in your home, for example could interfere with key fobs that have the same frequency. This could affect the remote control of your car.
Faulty OBDII scan tool
There are a number of reasons why a scan tool may not work. Some are more complex than others.
Professional scan tools enable a mechanic observe the car's network, and run various self-tests. These are real time savers, however they are also extremely expensive, out of the budget of many DIYers.
If your OBD2 scan tool won't power on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's possible that a fuse is blowing. This is the most frequent cause of scan tool failure. It is often easy to fix the problem by replacing the fuse that was blown.
