Fiat Panda Key Fob Replacement Fiat Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car that allows it to unlock doors or turn on the motor However the key fob may stop working for several reasons A dead battery for the coin is the most common cause of key fob malfunctions Other causes include water damage a faulty receiver module and signal interference Dead Coin Battery If the battery in your key fob has failed the initial thing to do is replace it Use a brand new button battery with the same size voltage and specification like the previous one If the key fob was exposed to water for example a splash of rain or salt water at the beach it will need to be cleaned before it is able to be used again The best method is to use an old towel soaked in isopropyl or electronic cleaner If the key fob has not been exposed to water but remains inoperable it could be because of a problem with the receiver module or an internal electronic chip In these instances it is possible to reprogramme the key fob with an OBDII scanner may aid Water Damage If your key fob took submerged in a puddle or pool or taken a trip down the washing machine you could be suffering some water damage It is usually possible to fix it by taking the batteries off and cleaning the circuit board with rubbing alcohol Its best to let the fob dry completely before putting in a brand new battery You could have a damaged module in the event that your remote stops working after replacing the battery or changing the programming You can find information on reprograming the majority of remote keys on YouTube or consult your owners manual You can also reset the computer in your car with the OBDII scanner tool Faulty Receiver Module The key fob is equipped with a chip that communicates with the vehicles system This chip will stop sending and receiving signals to the car if damaged A key fob falling off can cause this as well as water exposure If your key fob stopped functioning due to water exposure it is possible fix the issue if you clean the chip with electronic cleaner or isopropyl alcohol If the key fob doesnt respond to cleaning it is possible that the receiver module has issues and needs to be replaced A malfunctioning receiver module could also cause the remote control key to stop working This usually happens due to electromagnetic interference A malfunctioning electronic chip The electronic chip inside your key fob is a vital part in the antitheft security system of your car It transmits a message the immobiliser in your car to determine whether the key is legitimate If the chip is damaged or broken your car will not start A damaged chip could be caused by interference from objects bad weather or transmitters in the vicinity of your vehicle In this instance you will need a new key fob Contacts for the battery that are damaged The battery contacts of the fobs key can be damaged by excessive usage If theyre bent or broken the fob wont send any signals to the receiver modules inside the vehicle Modern fobs 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 contains chip that communicates with the immobilizer system of the vehicle to begin it The system utilizes the red keys of older vehicles or the crypto coding system in modern vehicles If the chip is defective and needs to be replaced Problematic 12 Volt Battery A faulty battery can cause the remote to stop working If this happens the cars computer system will not recognize that the remote is inside the vehicle Before you replace the battery you should test it with a an voltmeter to gauge its capacity A fully charged battery will read 126 volts If fiat replacement key thekeylabcouk drops significantly its time to change it To determine the capacity of a battery put an electrical load on it for a few minutes This will take off approximately 1 of the surface charge Then take another measurement of the voltage The longer the battery is able to hold its voltage the better its capacity Ideal is that it stays at or near 12 volts for several minutes Radio Signal Faulty Radio Signal This is the main reason for keys not sending signals to a car The battery is able to be replaced to resolve this problem It is crucial to buy an identical battery dimensions and voltage as the original Fobs can take a lot abuse but theyre also not impervious to destruction Battery contacts and buttons can be damaged through rough handling A signal may also be interrupted by other objects or transmitters that use the same frequency A light control panel in your home for instance can interfere with key fobs using the same bandwidth This can interfere with the remote control in your car Afflicted OBDII Scan Tool There are many reasons why scanners may not work Certain are more complicated than others Professional scan tools allow a mechanic to look over the cars networks and run a variety of selftests They can be huge time savers however theyre also expensive out of the budget of many DIYers If your OBD2 scanner doesnt work examine the voltage at terminal 16 scan tool power and terminal 4 chassis ground If both are in good condition its possible that a fuse has blown This is the most common reason for failures of the scanner The simple fix is usually to replace the fuse that is blowing up
