Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car in order to unlock doors or start the motor. However, the fob could stop working due to a variety of causes.
A dead battery for the coin is the most frequent reason for the malfunction of a key fob. Other causes are water damage or a malfunctioning module and interference signals.
Dead Coin Battery
If your key fob battery has failed, the initial step is to replace it. Use a button cell battery that has the same voltage, size and specifications as the old one.
If the key fob was exposed to water, such as a splash of rain or salt water on 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 be the solution.
If the key fob isn't working despite not being exposed to water, it could be due to a glitch in the receiver module or in the internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner could aid.
Water Damage
If your key fob has gotten submerged in a puddle or pool, or taken a trip through the washing machine, you could be suffering some water damage. It's possible to get it back in working order by removing the batteries and cleaning the circuit board with ruby alcohol. It's best to let the fob dry completely before putting in a brand new battery.
If your key fob isn't working even after replacing the battery and changing the program, you could have a malfunctioning receiver module. Reprogramming instructions are available for most remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.
Faulty Receiver Module
The key fob contains a chip that 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 could cause this, as can water exposure. If your key fob isn't working due to exposure to water, you may be able to fix it if you clean the chip using electronic cleaner or isopropyl alcohol.
However, if the key fob is still unable to not respond even after cleaning it it is likely that the module is faulty and will require to be replaced. A defective receiver can cause the key to stop working. This usually happens due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob is a vital role in the anti-theft system of your car. It sends a signal to the immobiliser inside your car to tell it whether the key is genuine. If the chip is damaged or broken, the car will not start.
A malfunctioning chip could be caused by interference signals from objects like bad weather conditions or transmitters on the same frequency as your car. In this scenario you'll need an entirely new key fob.
Contacts of the battery may be damaged.
The battery contacts inside the key fob are delicate and can get damaged through repeated use. If they are bent, or broken, the fob won't transmit any signals to receiver modules inside the vehicle.
Modern fobs are equipped with rubber seals to keep out water. A splash of water or a light rain should be fine however, submerging them in saltwater may harm the chip's electronic components.
The key fob contains the chip that connects to the vehicle's immobilizer system in order to activate it. fiat 500 key fob replacement utilizes the old red keys that were used in older vehicles or the crypto coding system in newer cars. The chip must be replaced if it's damaged.
Faulty 12 Volt Battery
A defective battery can cause the key fob to cease working. The car's system will not recognize the remote if this happens.
Before replacing the battery, test it with an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically it is time to replace the battery.
Set an electrical load for a few moments on the battery to check its capacity. This will eliminate 1% of the surface charges. Then, test the voltage again. The longer the battery is able to keep its voltage steady greater is its capacity. Ideal is to hold at or near 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most common reason behind a key fob that stops sending signals to the car. The battery could be replaced to fix this issue. However, it is important to buy a new battery that is the same voltage and size as the original one.
Fobs aren't impervious to damage and can withstand a lot. The battery contacts and buttons could be damaged by rough handling.
Other transmitters or objects operating on the same frequency could also interfere with a signal. A light-control panel at your home, for instance can interfere with key fobs using the same frequency. This can interfere with your car's remote control.
Afflicted OBDII scan tool
There are many reasons why a scanner tool may not work. Some are more complex than others.
Professional scan tools let mechanics to observe the car's network, and run various self-tests. These tools can save a lot of time, but they are costly and not accessible to most DIYers.
If your OBD2 scan tool isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition, it's likely that a fuse has failed. This is among the most frequent reasons for failure of the scanner. The most straightforward fix is to replace the fuse that is blowing up.
