Fiat Panda Key Fob Replacement Fiat Panda key fobs contain an transponder chip that transmits a signal to your car to unlock the doors or start the engine However the fob may stop working due to a variety of causes The most common cause of key fob malfunction is a dead coin battery Other causes include water damage an inoperative receiver module and signal interference Dead Coin Battery If your key fobs battery has died the first step is to replace it Use a new button cell battery with identical in size voltage and specification like the previous one If the key fob was exposed to water such as saltwater or rain at the beach it must be cleaned before using again A paper towel soaked in isopropyl alcohol or electronic cleaner will help If the key fob isnt working despite not being exposed to water it could be due a malfunction in the receiver module or even in the internal electronic chip In these situations reprogramming the key fob with an OBDII scanner might help Water Damage If your key fob has taken a bath in the puddle or pool or walked through the washing machine you may have some water damage Its usually possible to get it back in working order by taking the batteries off and cleaning the circuit board using rubbing alcohol Its a good idea to let the fob dry completely before installing a new battery There could be a problem with the module in the event that your key fob stops working after replacing the battery or updating You can find information on reprogramming most vehicles remote keys on YouTube or refer to the owners manual You can also reset the computer of your vehicle using the OBDII scanner tool fiat punto keys contains a chip that communicates with the vehicles system The chip will stop sending and receiving signals to the car when it is damaged This can be caused by dropping the key fob or through exposure to water If the key fob stops working after water exposure it may be possible to fix it by cleaning the chip using isopropyl alcohol or an electronic cleaner If the key fob still does not respond after cleaning it there is a good chance that the module is defective and needs to be replaced A defective receiver can cause the key to stop working This is often caused by electromagnetic interference Electronic chip that is malfunctioning The electronic chip in your key fob plays an important role in the antitheft system of your vehicle It sends a signal the immobiliser unit of your car to inform it whether or not the key is genuine The car will not start if the chip is damaged A malfunctioning chip could be caused by interference signals from objects or weather conditions that are bad or transmitters operating on the same frequency close to your vehicle In this instance you will need a new key fob Faulty Battery Contacts The battery contacts of the fobs battery can be damaged by excessive usage If theyre damaged or bent the fob will not transmit any signals to the receiver modules inside the car Modern fobs come with rubber seals to keep out water Submerging them in water even if its just the slightest splash or drizzle could harm the electronic chip The key fob contains a chip that communicates with the vehicles immobilizer system to begin it It uses the old red keys in older vehicles or the cryptocoding system used in the latest vehicles This chip will have to be replaced if its damaged Problematic 12 Volt Battery A defective battery can cause the key fob not to function When this occurs the cars computer system wont recognize that the remote is within the vehicle Before replacing the battery test it using a an voltmeter for determining its capacity A fully charged battery will display 126 volts If the reading falls significantly then its time to replace it To test the batterys power place an electrical load on it for a couple of minutes This will remove 1 of the surface charges Then measure the voltage again The longer a battery is able to keep its voltage steady greater is its capacity It is ideal to maintain close to 12 volts during several minutes Faulty Radio Signal This is the main reason for a keyfob that ceases to send signals to the car This problem can be solved by replacing the battery It is important to buy a battery that has the same dimensions and voltage as the original Fobs arent impervious to damage and can withstand a lot Contacts and buttons on batteries can be damaged by rough handling The signal could also be impacted by other objects or transmitters that operate on the same frequency For example a lightcontrol panel close to your home can transmit interference on the same frequency that key fobs use This could cause interference with the remote control of your car Incorrect OBDII scan tool There are a number of reasons why a scanner may not work Some are more complicated than others Professional scan tools enable mechanics to examine the cars systems and conduct a variety selftests These can be real timesavers but they are also extremely expensive and beyond the range of most DIYers If your OBD2 scanner wont turn on examine the voltage at terminal 16 scan tool power and terminal 4 chassis ground If all is fine it could be that a fuse has ruptured This is one of the most frequent causes of scan tool failure The most straightforward fix is to replace the fuse which has blown
