Check Out: How Fiat 500 Keys Is Taking Over And What Can We Do About It
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car to open doors or turn on the motor. The fob can stop functioning due to a variety of reasons.
The most common reason for key fob failure is an inoperable coin battery. Other causes are water damage, a faulty receiver module and signal interference.
Dead Coin Battery
Replace the battery if the key fob has died. Choose a new button battery that has exactly the same size, voltage and specifications as the old one.
If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before being used again. A paper towel soaked in alcohol or electronic cleaner will help.
If the key fob hasn't been exposed to water but still does not work it could be due to a problem with the receiver module or an internal electronic chip. In these instances, reprogramming the key fob using an OBDII scanner may help.
Water Damage
If your key fob has taken submerged in a pool or puddle, or taken a trip to the washing machine, you could be suffering some water damage. It is usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is best to allow the device to completely dry prior to installing a battery.
If your key fob isn't working even after replacing the battery and reconfiguring it, you may have a faulty receiver module. You can find reprogramming procedures for all vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob is equipped with a chip which communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob can cause this, as could water exposure. If the key fob stopped working after exposure to water, it may be possible to fix the issue by cleaning the chip using isopropyl ethanol or electronic cleaner.
If the key fob still does not respond after cleaning it then it is likely that the module is defective and needs to be replaced. A malfunctioning receiver could cause the key to cease to function. This is typically caused by electromagnetic interference.
Electronic chip that is malfunctioning
The chip inside your key fob plays an important part in the anti-theft security system of your vehicle. It transmits a message the immobiliser inside your car to tell it if the key is valid. The car won't start in the event that the chip is damaged.
A defective chip could be caused by interference caused by objects, bad weather or transmitters close to your vehicle. In this situation an upgrade to the fob will be required.
Contacts to the battery are not working properly.
The battery contacts in a key fob are very delicate and can get damaged when used for long periods of time. If they're bent, or damaged, the fob will not send any signals to the receiver modules inside the vehicle.
Modern fobs come with rubber seals that keep out water. In the event of submerging them in water, even if it's just an occasional drizzle or splash can harm the chip's electronic circuit.
The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. The system utilizes the old red keys for older vehicles or the cryptocoding system found in newer cars. This chip needs to be replaced if it's faulty.
The 12 Volt Battery is faulty
A faulty battery may cause the key fob not to function. When this occurs the car's computer will not be able to recognize that the remote is inside the vehicle.
Before replacing the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly, it is time to replace the battery.
Install an electrical charge for a short period of time on the battery to determine its capacity. This will take away 1percent of the surface charges. Then, you can measure the voltage again. The greater the battery's capacity, the longer it can maintain its voltage. Ideal is that it stays close to 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the most frequent reason for a key fob that ceases to send signals to the car. fiat 500 key can be resolved by replacing the battery. It is crucial to buy a battery that has the same dimensions and voltage as the original.
Fobs are not indestructible and can withstand a lot. Contacts and buttons on batteries can be damaged by rough handling.
Other transmitters or objects that use the same frequency can also disrupt the signal. For instance, a light control panel that is near your home could transmit interference on the same frequency that key fobs utilize. This could affect the remote control of your car.
Problems with OBDII Scan Tool
There are many reasons why scanners may not perform. Certain are more complicated than others.
Professional scan tools enable mechanics to monitor the car's network and run a range of self-tests. These tools can save time, but they are costly and out of reach for the majority of DIYers.
If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine, a fuse may have ruptured. This is among the most frequent causes of scan tool failure. The easiest fix is to replace the fuse that is blowing up.
