Fiat 500 Keys: A Simple Definition
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that sends signals from the fob to the car in order to unlock doors or start the motor. The fob might stop working due to a variety reasons.
A dead battery for the coin is the most common reason for the malfunction of a key fob. Other causes include water damage a faulty receiver module and signal interference.
Dead Coin Battery
Replace the battery in case your key fob is dead. Make use of a new button battery with 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 should be cleaned before using again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can do the trick.
If the key fob has not been exposed to water but it is still not working it could be because of a problem with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob using an OBDII scanner may help.
Water Damage
You could have water damage if your key fob was submerged in a pool, puddle or washing machine. It's generally possible to get it working by removing the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea allow the fob to dry completely before putting in 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. You can find reprogramming procedures 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 contains a chip that connects to the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This could be due to dropping the key fob or due to exposure to water. If the key fob is not working after water exposure it may be possible to repair the issue by cleaning or cleaning the chip using isopropyl alcohol or an electronic cleaner.
If the key fob won't respond to cleaning, it is possible that the module has a fault and needs to be replaced. A faulty receiver can also cause the key to not work. This is usually caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip in your key fob is a vital role in the anti-theft system of your vehicle. It transmits a message the immobiliser in your car that tells it whether the key is legitimate. If the chip is damaged or broken, your car won't start.
A malfunctioning chip can be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this instance you'll need a new key fob.
Contacts of the battery may be damaged.
The battery contacts of the fob's battery can be damaged by excessive usage. If they are bent or broken the fob will not be able to send any signals to the receiver modules in the car.
Modern fobs have rubber seals that block out water. Immersing them in water, even if it is just a light drizzle or splash, can damage the electronic chip.
The key fob has a chip which communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in vehicles that are more modern and the older red key system for older models. This chip needs to be replaced if it's defective.
Problematic 12 Volt Battery
A malfunctioning battery could cause the remote to stop working. If this happens the car's computer won't recognize that the remote is inside the vehicle.
Before you replace the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly, it is time to replace the battery.
Set an electrical load for a short time on the battery to test its capacity. This will eliminate about 1 percent of the charge on the surface. Then, you can measure the voltage. The higher the capacity of the battery and the longer it can keep its voltage. The ideal is to keep it close to 12 volts during several minutes.
Faulty Radio Signal
This is the most typical reason for a key fob that ceases to send signals to the car. The battery can be replaced to solve this problem. fiat panda key is important to buy a battery with the same voltage and dimensions as the original.
Fobs are subject to a lot of abuse, but they're also not indestructible. The battery buttons and contacts are brittle which means they could be bent or damaged by excessive use.
A signal may also be disrupted by other objects or transmitters which use the same frequency. For example, a light-control panel near your home may send interference on the same bandwidth that key fobs utilize. This could interfere with the remote control of your car.
Incorrect OBDII Scan Tool
There are many reasons why a scan tool might not work. Certain are more complicated than others.
Professional scan tools let mechanics to observe the car's network and run various self-tests. They can be huge time savers, however they can also be very expensive, out of the budget of many DIYers.
If your OBD2 scanner won't start Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK it's likely that a fuse has blown. This is one of the most common causes of scan tool failure. The easiest fix is to replace the blown fuse.
