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 turn on the motor. The fob could stop working for a variety. A dead coin battery is the most common reason for a key fob malfunction. Other causes include water damage, an inoperative receiver module and signal interference. Dead Coin Battery If your key fob's battery has died, the first step is to replace it. Make use of a new button battery with the same size, voltage and specifications as the previous one. If the key fob has been exposed to water, like 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 soaked with isopropyl alcohol or electronic cleaner will be the solution. If the key fob hasn't been exposed to water, but still does not work it could be because of an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan could help in these cases. Water Damage If your key fob has taken submerged in a puddle or pool, or taken a trip down the washing machine, it could have some water damage. It's possible to get it back in working order by taking out the batteries and cleaning the circuit board with rubbing alcohol. It's best to let the fob dry completely before putting in a brand new battery. There could be a problem with the module in the event that your key fob stops working after replacing the battery or changing the programming. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset the car's computer using the OBDII scanner tool. Faulty Receiver Module The key fob's chip is a chip which communicates with the vehicle's system. If the chip is damaged, it cannot longer send and receive signals to the vehicle. Dropping the key fob could cause this, as well as water exposure. If the key fob has stopped working after water exposure it could be possible to fix it by cleaning the chip using isopropyl ethanol or electronic cleaner. If the key fob won't respond to cleaning, it's possible that the module has issues and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to not function. This is usually caused by electromagnetic interference. Faulty Electronic Chip The electronic chip inside your key fob plays a vital role in the anti-theft system of your vehicle. It sends a signal to the immobiliser unit in your car to determine whether the key is legitimate. The car will not start if the chip is damaged. A damaged chip could be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this scenario you'll need an entirely new key fob. Contacts for the battery that are damaged The battery contacts in the key fob are delicate and could be damaged by repeated use. If they're bent or damaged, the fob will not send any signals to the receiver modules in the vehicle. Modern fobs are constructed with rubber seals to keep out water. A splash of water or light rain is fine, but submerging them in saltwater could harm the electronic chip. The key fob comes with chip that communicates with the immobilizer system of the vehicle to start it. This system utilizes cryptocoding systems in the latest vehicles or the red key system in older ones. If the chip is damaged, it will need to be replaced. Faulty 12 Volt Battery A damaged battery can cause the key fob to cease working. When this occurs the car's computer won't recognize that the remote is in the vehicle. Before replacing the battery, test it using a an voltmeter to gauge its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly, it's time to replace it. To test a battery's capacity, place an electrical load on it for a couple of minutes. This will eliminate 1percent of the surface charges. Then, you can measure the voltage. The greater the battery's capacity is, the longer it will maintain its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes. Faulty Radio Signal This is the most common cause of a key fob that ceases to send signals to the car. The battery could be replaced to fix this problem. But, it is essential to choose a battery that is the same size and voltage as the original one. Fobs are subject to a lot of abuse, but they're also not impervious to destruction. Contacts and buttons on batteries can be damaged through rough handling. fiat keys or transmitters using the same frequency can disrupt the signal. A light-control panel in your home, for example can interfere with key fobs that have the same frequency. This could cause interference with the remote control in your car. Problems with OBDII Scan Tool There are a variety of reasons why scanner tools may not work. Some are more complex than others. Professional scan tools enable mechanics to look over the car's networks and run various self-tests. These are great time savers, but they can also be very expensive, and beyond the reach of most DIYers. If your OBD2 scan tool fails to turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it could be that a fuse has failed. This is one of the most frequent causes of scan tool failure. The most straightforward fix is to replace the fuse which has blown.
