Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that sends signals from the fob to the car to unlock doors or turn on the motor. However, the key fob may stop working due to a variety of causes.
The most frequent cause of key fob failure is an inoperable coin battery. Other causes include water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery in case your key fob is dead. Use a new button cell battery that is exactly the same size, voltage and specifications as the previous one.
If the key fob was exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will work wonders.
If the key fob isn't working despite not being exposed water it could be due to a glitch in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan can help in these cases.
Water Damage
If your key fob's battery has taken submerged in a puddle or pool or walked to the washing machine, it could have some water damage. It is usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the fob completely dry before putting in a battery.
If your key fob has stopped working, even after replacing the battery and programming it again, you might have a defective receiver module. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer of your car using the OBDII scanner tool.
Faulty Receiver Module
The key fob's chip is a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or through exposure to water. If the key fob stops functioning after exposure to water, it is possible to fix the issue by cleaning the chip using isopropyl ethanol or electronic cleaner.
If the key fob does not respond to cleaning, it is possible that the receiver module has issues and needs to be replaced. A defective receiver can cause the key to stop working. This is typically caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob is a vital role in the anti-theft system in your car. It sends a message to the immobiliser inside your car to inform it if the key is valid. Your car won't start when the chip is damaged.
A damaged chip could be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency in close proximity to your car. In this instance you'll require an entirely new key fob.
Contacts for the battery that are damaged
The battery contacts on the key fob could be damaged due to heavy use. If they are bent, or damaged, the fob will not send any signals to the receiver modules in 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 a light drizzle or splash could harm the chip's electronic circuit.
The key fob is equipped with an electronic chip that communicates with the vehicle's immobilizer in order to activate it. The system uses the old red keys in older vehicles as well as the crypto coding system in the latest vehicles. This chip will need to be replaced if it's damaged.
Problematic 12 Volt Battery
A malfunctioning battery could cause the remote to cease working. The car's computer may not recognize the remote when this occurs.
Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.
Set an electrical load for a few moments on the battery to test its capacity. fiat car key will eliminate approximately 1 percent of the charge on the surface. Then, you can measure the voltage. The longer a battery can keep its voltage steady greater is its capacity. The ideal scenario is to keep it close to 12 volts several minutes.
Faulty Radio Signal
This is the most frequent cause of a key fob that ceases to send signals to the car. The battery can be replaced to fix this problem. However, it is crucial to buy a new battery with the same voltage and size as the original.
Fobs are not indestructible and can be damaged by a lot. Contacts and buttons on batteries can be damaged through rough handling.
Other transmitters or objects using the same frequency can also interfere with the signal. A light-control system in your home, for example could interfere with key fobs that use the same frequency. This can interfere with the remote control of your car.
Problems with OBDII Scan Tool
There are a number of reasons why a scanner might not work. Some are more complicated than others.
Professional scan tools let mechanics to observe the car's networks and run various self-tests. They can be huge time savers, but they are also extremely expensive, and out of the reach of most DIYers.
If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine the fuse could have ruptured. This is the most typical reason for failure of the scan tool. It is often simple to fix the issue by replacing the fuse that was blown.
