Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors or start the engine. However, the fob may not function due to a variety of reasons.
The most frequent cause of key fob malfunction is the battery of the coin is dead. Other causes include water damage or a malfunctioning module and interference signals.
Dead Coin Battery
Replace the battery if your key fob has gone out of service. Choose a new button battery that is exactly the same size, voltage and specifications as the original.
If the key fob was exposed to water (such as rain or saltwater at the beach) it must be cleaned before using again. The best method is to use a paper towel that has been soaked in isopropyl or an electronic cleaner.
If the key fob has not been exposed to water but it is still not working, there may be an issue with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner can aid.
Water Damage
If your key fob has gotten an immersion in the pool or puddle or even a trip down the wash machine, you could be suffering some water damage. It is usually possible to fix it by getting rid of the batteries and cleaning the circuit board using rubbing alcohol. It's a good idea let the fob dry completely prior to installing a new battery.
If your key fob has stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. There are instructions for reprograming the majority of remote keys on YouTube or consult your 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's chip is a chip which communicates with the vehicle's system. The 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 exposure to water. If your key fob stopped functioning due to water exposure it is possible to fix it by attempting to clean the chip using electronic cleaner or isopropyl ethanol.
If the key fob does not respond to cleaning, it is possible that the component has a fault and needs to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The electronic chip inside your key fob plays an important part in the anti-theft security system in your car. It sends out a signal the immobiliser unit inside your car to inform it whether or not the key is genuine. The car won't start in the event that the chip is damaged.
A defective chip can be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency in close proximity to your car. In this situation an upgrade to the fob will be needed.
Contacts for the battery that are damaged
The battery contacts in a key fob are very delicate and may be damaged with hard usage. If they're bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.
fiat doblo key come with rubber seals to keep out water. A splash of water or a light rain is acceptable However, submerging them in saltwater can harm the electronic chip.
The key fob comes with chip that communicates with the immobilizer system of the vehicle, allowing it to start it. This system makes use of cryptocoding systems in modern vehicles as well as the traditional red key system for older ones. If the chip is not working properly, it will need to be replaced.
A faulty 12 Volt battery
A malfunctioning battery could cause the key fob to function. The car's computer may not recognize the remote if this occurs.
Before you replace the battery, test it using a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly it is time to replace the battery.
To determine the capacity of a battery put an electrical load on it for a couple of minutes. This will remove about 1 percent of the charge on the surface. Then, test the voltage again. The longer a battery can hold its voltage more effectively, the greater its capacity. Ideally, it will remain close to 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the most common reason for a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. But, it is essential to purchase a battery that is the same voltage and size as the original one.
Fobs aren't impervious to damage and are susceptible to damage. The battery buttons and contacts are brittle and are susceptible to being bent or damaged by the force of.
A signal can also be interrupted by other objects or transmitters that use the same frequency. A light-control system in your home, for example can interfere with key fobs that have the same bandwidth. This could affect the remote control of your car.
The tool is not working properly. OBDII scan tool
There are many reasons why scanner tools may not function. Certain are more complicated than others.
Professional scan tools permit mechanics to monitor the car's network and run a variety of self-tests. These tools can help save time, but are costly and are out of reach for most DIYers.
If your OBD2 scan tool fails to turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK it could be that a fuse has been blown. This is one of the most frequent causes of scan tool failure. The simple fix is usually to replace the fuse which has blown.
