Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car in order to unlock doors or start the motor. fiat ducato key might stop working due to a variety of reasons.
A dead battery for the coin is the most common cause of key fob malfunctions. Other causes include water damage or a malfunctioning module and interference signals.
Dead Coin Battery
If your key fob's battery has failed, the initial step is to replace it. Use a button cell battery with the same voltage, size, and specifications as your previous one.
If the key fob was exposed to water (such as rain or saltwater at the beach) It must be cleaned before using again. A paper towel soaked in isopropyl alcohol or electronic cleaner can help.
If the key fob has not been exposed to water but remains inoperable it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob through an OBDII scan could aid in these situations.
Water Damage
You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. You can usually restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely prior to installing a new battery.
You may have a faulty module in the event that your key fob stops working after replacing the battery or replacing it with. You can find instructions for changing the programming of most remote keys on YouTube or refer to your owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.
Faulty Receiver Module
The key fob contains the chip that communicates the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. A key fob falling off can cause this, as can exposure to water. If the key fob stopped working after exposure to water, it could be possible to fix the issue by cleaning the chip using isopropyl alcohol, or electronic cleaner.
However, if the key fob is still unable to not respond after cleaning it, then it is likely that the component is damaged and will need to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside the key fob is an essential component of the anti-theft systems in your car. It transmits a message to the immobiliser inside your car to inform it whether the key is genuine. The car won't start in the event that the chip is damaged.
A faulty chip may also be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this scenario you'll require an entirely new key fob.
Contacts for the battery that are defective
The battery contacts on the fob's key can be damaged by excessive usage. If they're bent or broken, the fob won't transmit any signals to receiver modules inside the vehicle.
Modern fobs have rubber seals that block out water. A splash of water or a light rain should be fine however, submerging them in saltwater can damage the chip's electronic components.
The key fob is equipped with the chip that connects to the vehicle's immobilizer in order to allow it to start. The system relies on cryptocoding systems in modern vehicles or the red key system used in older models. This chip will need to be changed if it is faulty.
Faulty 12 Volt Battery
A malfunctioning battery could cause the remote to cease working. The car's system will not recognize the remote when this happens.
Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly it's time to change it.
To test the battery's power to determine its capacity, put an electric load on it for a couple of minutes. This will take away 1% of the surface charges. Then measure the voltage again. The longer the battery is able to keep its voltage steady, the better its capacity. Ideally, it will remain close to 12 volts for several minutes.
Faulty Radio Signal
This is the most typical reason for a key fob that ceases to send signals to the car. This issue can be fixed by replacing the battery. It is essential to purchase batteries that have the same dimensions and voltage as the original.
Fobs are subject to a lot of abuse, but they're not impervious to destruction. The battery contacts and buttons are delicate which means they could be bent or damaged by rough usage.
The signal could also be interrupted by other transmitters or objects which use the same frequency. A light-control system in your home, for example could interfere with key fobs that use the same bandwidth. This could affect the remote control of your car.
Afflicted OBDII scan tool
There are many reasons a scanner tool may not function. Some are more complex than others.
Professional scan tools allow a mechanic to examine the car's systems 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 isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the chances are that a fuse is blowing. This is the main cause of scan tool failure. It is often easy to fix the problem by replacing the fuse blowing up.
