Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends signals to your car to unlock the doors or start the engine. However, the fob may be inoperable due to various reasons.
The most common cause of key fob malfunction is the battery of the coin is dead. Other reasons include water damage, the receiver module is defective and signal interference.
Dead Coin Battery
If your key fob's battery is dead, the first thing to do is replace it. Choose a new button battery that is exactly the same size, voltage and specification like the previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) it must be cleaned prior to using it again. A paper towel soaked in alcohol or electronic cleaner can help.
If the key fob doesn't working despite being not exposed to water it could be due to a glitch in the receiver module or internal electronic chip. Reprogramming the keyfob with an OBDII scan may aid in these situations.
Water Damage
You could have water damage if your key fob was submerged in a puddle, pool or washing machine. It's generally possible to fix it by removing the batteries and cleaning the circuit board using ruby alcohol. It is best to let the board completely dry prior to installing a battery.
It could be that you have a defective module in the event that your key fob stops working after replacing the battery or replacing it with. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.
Faulty Receiver Module
The key fob contains a chip that connects to the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob, or by water exposure. If the key fob you have purchased has stopped working due to water exposure, you may be able to fix it by attempting to clean the chip with electronic cleaner or isopropyl ethanol.
If the key fob does not respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A faulty receiver module can also cause the remote control key to stop working. This usually happens due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip in your key fob plays an important function in the anti-theft security system of your car. It sends out a signal the immobiliser unit of the vehicle to determine whether the key is genuine. 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 near your vehicle. In this situation you'll require a new key fob.
Contacts of the battery may be damaged.
The battery contacts on a key fob can be damaged by heavy usage. If they're bent or broken, the fob won't send any signals to the receiver modules inside the vehicle.
Modern fobs feature rubber seals to keep out water. A splash of water or light rain should be fine however, submerging them in saltwater may cause damage to the electronic chip.
The key fob has a chip that communicates with the vehicle's immobilizer to allow it to begin it. This system utilizes cryptocoding systems in newer vehicles and the older red key system for older ones. If the chip is not working properly, it will need to be replaced.
Problems with 12 Volt Batteries
A faulty battery can cause the remote to cease to function. When fiat keys replacement occurs the car's computer will not recognize that the remote is in the vehicle.
Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly, it is time to replace the battery.
Place an electrical load for a few moments on the battery to determine its capacity. This will take away one percent of the surface charges. After that, measure the voltage. The longer the battery is able to hold its voltage more effectively, the greater its capacity. It is ideal to maintain at or near 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most typical reason for the key fob to stop sending signals to a car. The battery could be replaced to fix this issue. It is however important to choose a battery that is the same voltage and size as the original.
Fobs aren't impervious to damage and are susceptible to damage. The battery buttons and contacts are delicate and can be bent or broken by rough usage.
A signal may also be disrupted by other transmitters or objects that use the same frequency. A light-control panel in your home, for example could interfere with key fobs using the same bandwidth. This could affect the remote control of your car.
Incorrect OBDII Scan Tool
There are a number of reasons why a scanner might not work. Some are more complex than others.
Professional scan tools enable mechanics to monitor the car's network and perform various self-tests. These are great time savers, but they're also expensive and are out of the reach of most DIYers.
If your OBD2 scan tool doesn't turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine, a fuse may have failed. This is the most frequent cause of scan tool failure. It is typically simple to fix the issue by replacing the fuse blowing up.
