Fiat Panda Key Fob Replacement Fiat Panda key fobs contain a transponder chip that sends signals to your car to open the doors or start the engine. However, the key fob may stop working for several reasons. The most common cause of key fob failure is the battery of the coin is dead. Other causes are water damage, a faulty module, and interference signals. Dead Coin Battery If the battery in your key fob has failed, the initial thing to do is replace it. Make use of a button cell battery that has the same voltage, size, and specifications as the previous one. If the key fob has been exposed to water, such as a splash of rain or salt water on the beach, it will have to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can help. If the key fob hasn't been exposed to water, but still does not work it could be a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan could help in these cases. Water Damage You could have water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to restore it's functionality by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the fob completely dry prior to installing a battery. If your key fob stopped working even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find reprogramming procedures for most remote key fobs on YouTube or in the owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool. Faulty Receiver Module The key fob is equipped with a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if damaged. The key fob being dropped can cause this, as well as water exposure. If your key fob isn't working due to water exposure and you are unable to fix it by attempting to clean the chip with electronic cleaner or isopropylethanol. If the key fob doesn't respond to cleaning, it is possible that the receiver module has a fault and needs to be replaced. A faulty receiver module can also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference. Faulty Electronic Chip The electronic chip in your key fob is a vital part in the anti-theft security system of your car. It sends a signal to the immobiliser unit in your vehicle to tell it whether the key is genuine. Your car will not start when the chip is damaged. A malfunctioning chip can be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this scenario you'll need an entirely new key fob. fiat key replacement of a key fob can be damaged by heavy usage. If they're bent or broken, the fob won't send any signals to receiver modules inside the vehicle. Modern fobs are designed with rubber seals in order to keep out water. A splash of water or light rain should be fine However, submerging them in salt water could cause damage to the chip's electronic components. The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle in order to start it. This system makes use of cryptocoding systems in modern vehicles and the older red key system in older ones. If this chip is faulty and needs to be replaced. Problematic 12 Volt Battery A faulty battery can cause the key fob to cease working. The car's computer may not recognize the remote if this occurs. Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly it's time to change it. Place an electrical load for a short period of time on the battery to check its capacity. This will eliminate 1percent of the charges. Then take another measurement of the voltage. The longer the battery is able to hold its voltage and the higher its capacity. Ideal is that it stays close to 12 volts over several minutes. Problems with Radio Signal This is the most typical reason for the key fob to stop sending signals to a car. The battery can be replaced to fix this problem. However, it is important to purchase a battery that is the same voltage and size as the original. Fobs aren't impervious to damage and are susceptible to damage. Contacts and buttons on batteries can be damaged through rough handling. The signal could also be interrupted by other objects or transmitters that use the same frequency. For instance, a lighting control panel in your home could transmit interference using the same frequency that key fobs utilize. This can interfere with the remote control in your car. Incorrect OBDII scan tool There are many reasons why scanners don't perform. Some are more complex than others. Professional scan tools enable mechanics to observe the car's network and run various self-tests. These tools can save you a lot of time, but they're expensive and are out of reach for the majority of DIYers. If your OBD2 scan tool fails to turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are both present the chances are that a fuse has been blown. This is the most frequent cause of scan tool failure. It is usually easy to fix the problem by replacing the fuse that was blown.
