fiat 500 key cover Panda Key Fob Replacement
fiat 500 key not working Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car to unlock doors or turn on the motor. The fob might stop working due to a variety reasons.
A dead battery for the coin is the most common reason for malfunctioning keys. Other causes include water damage a faulty receiver module, and signal interference.
Dead Coin Battery
Replace the battery if the key fob is dead. Choose a button battery that has the same voltage, size and specifications as your previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned prior to being used again. The best method is to use a paper towel soaked with isopropyl or an electronic cleaner.
If the key fob is not working despite not being exposed 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 that reprogramming the key fob using an OBDII scanner may assist.
Water Damage
You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's possible to get it working by taking out 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.
If your key fob has stopped working, even after replacing the battery and programming it again, you might have a faulty receiver module. You can find reprogramming instructions for most remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob's chip is the chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. 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 exposure to water or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob won't respond to cleaning, it's likely that the module is in an issue and must be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside the key fob is an essential element of the anti-theft device in your vehicle. It sends a signal the immobiliser device in the vehicle to determine whether the key is legitimate. If the chip is damaged or broken, your vehicle will not start.
A damaged chip could be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this scenario it is likely that a new fob would be required.
Faulty Battery Contacts
The battery contacts of a key fob can be damaged through heavy use. If they're damaged or bent, the fob won't send any signals to the receiver modules inside the car.
Modern fobs are equipped with rubber seals to keep out water. Immersing them in water, even if it is just the slightest splash or drizzle, can damage the chip's electronic components.
The key fob houses a chip that communicates with the vehicle's immobilizer system in order to activate it. It uses the old red Locked Keys In Fiat 500 for older vehicles, or the cryptocoding system found in the latest vehicles. This chip needs to be replaced if it's damaged.
Problems with 12 Volt Batteries
A malfunctioning battery could cause the key fob to cease to function. The car's computer may not recognize the remote if this occurs.
Before you replace the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.
To test the battery's capacity put an electrical load on it for a few minutes. This will remove about 1 percent of the charge on the surface. Then, test the voltage again. The longer a battery is able to hold its voltage more effectively, the greater its capacity. Ideally, it should remain at or near 12 volts for several minutes.
Problems with Radio Signal
This is the most frequent reason for the key fob not sending signals to vehicles. This problem can be solved by replacing the battery. It is crucial to buy an identical battery voltage and dimensions as the original.
Fobs are not indestructible and can be damaged by a lot. Battery contacts and buttons can be damaged by rough handling.
Other objects or transmitters using the same frequency can interfere with a signal. A light control panel in your home, for instance can interfere with key fobs which use the same bandwidth. 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 complex than others.
Professional scan tools let mechanics to observe the car's network and perform various self-tests. These tools can save a lot of time, but they're expensive and out of reach for most DIYers.
If your OBD2 scanner isn't turning on Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the fuse could have ruptured. This is among the most common causes of failures in the scan tool. It is often simple to fix the issue by replacing the fuse blowing up.
