Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car to open doors or turn on the motor. fiat replacement key fob may stop working for a variety.
The most common reason for key fob malfunction is an inoperable coin battery. Other causes are water damage or a damaged module and interference signals.
Dead Coin Battery
Replace the battery if the key fob has gone out of service. Use a button cell battery that has the same voltage, size, and specifications as your previous one.
If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it needs to be cleaned before it can be used again. The best solution is to use the paper towel and soak it in isopropyl or electronic cleaner.
If the key fob is not working despite not being exposed to water, it could be due to a glitch in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob with an OBDII scan can help in these cases.
Water Damage
You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's possible to get it back in working order by taking out the batteries and cleaning the circuit board using rubbing alcohol. It's best to allow the fob to dry completely before putting in a brand new battery.
If your key fob stopped working, even after replacing the battery and reconfiguring it, you may have a defective receiver module. You can find instructions for the reprogramming of most remote keys on YouTube or in the owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.
Faulty Receiver Module
The key fob contains a chip which communicates with the vehicle's system. The 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 using electronic cleaner or isopropyl ethanol.
If the key fob doesn't respond to cleaning, it is possible that the module has issues 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 that is in your key fob is a vital role in the anti-theft system of your vehicle. It sends a signal to the immobiliser unit of the vehicle to determine whether the key is legitimate. Your car will not start if the chip is damaged.
A damaged chip could be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency as your vehicle. In this instance you'll require a new key fob.
Faulty Battery Contacts
The battery contacts inside the key fob are delicate and can get damaged by repeated use. If they're bent, or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.
Modern fobs are designed with rubber seals that keep out water. Immersing them in water, even if it's just small splash or drizzle, can damage the chip's electronic components.
The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle, allowing it to start it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system found in newer vehicles. This chip will need to be replaced if damaged.
A faulty 12 Volt battery
A faulty battery can cause the key fob to stop working. When this occurs, the car's computer system will not be able to recognize that the remote is in the vehicle.
Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly, it is time to replace the battery.
Set an electrical load for a few seconds on the battery to test its capacity. This will eliminate 1percent of the surface charges. Then, you can measure the voltage again. The longer a battery is able to hold its voltage and the higher its capacity. It is ideal to maintain close to 12 volts over several minutes.
The radio signal is not working properly. Radio Signal
This is the most frequent reason for a keyfob that stops sending signals to the car. The issue can be fixed by replacing the battery. But, it is essential to buy a new battery that has the same size and voltage as the original.
Fobs are not indestructible and are susceptible to damage. Contacts and buttons on batteries can be damaged by rough handling.
A signal may also be affected by other transmitters or objects which use the same frequency. A light-control panel at your home, for instance can interfere with key fobs which use the same frequency. This can affect the remote control of your car.
Afflicted OBDII Scan Tool
There are a variety of reasons why scanner tools may not work. Certain are more complicated than others.
Professional scan tools allow a mechanic to look over the car's networks and perform a variety of self-tests. These tools can save time, but they are costly and out of reach for most DIYers.
If your OBD2 scan tool fails to turn on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's likely that a fuse is blowing. This is one of the most common reasons for failure of the scanner. It is often easy to fix the problem by replacing the blown fuse.
