Fiat Panda Key Fob Replacement Fiat Panda key fobs contain an transponder chip that transmits an alert to your car to unlock the doors or start the engine However the fob can be inoperable due to various reasons The most common reason for key fob malfunction is the battery of the coin is dead Other causes include water damage malfunctioning receiver modules and signal interference Dead Coin Battery Replace the battery if the key fob has died Use a new button cell battery that is the same voltage size and specification as the old one If the key fob was exposed to water such as rain or saltwater at the beach it must be cleaned before using again A paper towel soaked with isopropyl alcohol or electronic cleaner will help If the key fob has not 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 may help in these instances Water Damage If your key fob has gotten immersed in a pool or puddle or even a trip through the washing machine you might have some water damage Its possible to get it working by getting rid of the batteries and cleaning the circuit board using ruby alcohol Its a good idea let the fob dry completely before putting in a brand new battery If fiat punto replacement key fob isnt working even after replacing the battery and changing the program you could have a problem with the receiver module You can find reprogramming instructions for most remote key fobs on YouTube or in the owners manual You can also try resetting the cars onboard computer with the OBDII scan tool Faulty Receiver Module The key fob has a chip that connects to the cars system The chip will stop sending and receiving signals to the car if damaged This can be caused by dropping the key fob or through exposure to water If your key fob has stopped working due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol If the key fob doesnt respond to cleaning its possible that the receiver module has a fault and needs to be replaced A damaged receiver can cause the key to not work This is usually due to electromagnetic interference A malfunctioning electronic chip The electronic chip in the key fob is an important component of the antitheft systems in your car It sends a signal to the immobiliser unit in the vehicle to determine whether the key is legitimate Your car will not start when the chip is damaged A defective chip could be caused by interference from other objects bad weather or transmitters located near your vehicle In this scenario youll require an entirely new key fob Contacts for the battery that are defective The battery contacts of the key fob could be damaged due to heavy use If they are broken or bent the fob will not send any signals to the receiver modules inside the car Modern fobs are made with rubber seals in order to keep out water Immersing them in water even if its only an occasional drizzle or splash could harm the chips electronic components The key fob contains chip that communicates with the immobilizer system of the vehicle to begin it This system makes use of cryptocoding systems in modern vehicles or the old red key system used in older ones If this chip is faulty it will need to be replaced The 12 Volt Battery is faulty A malfunctioning battery could cause the key fob not to function If this happens the cars computer will not be able to recognize that the remote is inside the vehicle Test the battery with an voltmeter prior to replacing it to determine its capacity A fully charged battery should read 126 volts If the reading drops significantly it is time to replace the battery Install an electrical charge for a short period of time on the battery to test its capacity This will remove about 1 of the charge on the surface Then you can measure the voltage again The longer the battery can hold its voltage the better its capacity The ideal is to keep it close to 12 volts during several minutes Problems with Radio Signal This is the most typical reason behind a key fob that ceases to send signals to the car The battery is able to be replaced to resolve this problem It is crucial to buy a battery with the same dimensions and voltage as the original Fobs endure a lot of abuse and they arent impervious to destruction The battery contacts and buttons are delicate and are susceptible to being bent or damaged by excessive use Other objects or transmitters using the same frequency could also disrupt a signal For instance a light control panel in your home could send interference on the same bandwidth that key fobs utilize This can interfere with the remote control in your car Faulty OBDII scan tool There are a number of reasons why a scanner could not function Some are more complex than others Professional scan tools enable mechanics to look over the cars networks and perform a variety of selftests These can be real timesavers but theyre also expensive and beyond the range of most DIYers If your OBD2 scanner doesnt work check the voltage on terminal 16 scan tool power and terminal 4 chassis ground If theyre all fine there is a chance that a fuse has blown This is one of the most frequent causes of a scan tool failing The most straightforward fix is to replace the fuse that has been blown
