Fiat Panda Key Fob Replacement Fiat Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car to unlock doors or turn on the motor However the fob could not function due to a variety of reasons The most common cause of key fob failure is the battery of the coin is dead Other causes are water damage the receiver module is defective and signal interference Dead Coin Battery Replace the battery in case your key fob has died Choose a button battery that has the same voltage size and specifications as the previous one If the key fob was exposed to water for example a splash of rain or salt water at the beach its going to need to be cleaned before it can be used again The trick is to use a paper towel soaked with isopropyl or electronic cleaner If the key fob hasnt been exposed to water but it is still not working it could be due to a problem with the receiver module or an internal electronic chip Reprogramming the keyfob through an OBDII scan may help in these instances Water Damage If your key fob has taken submerged in a puddle or pool or walked down the washing machine you may have some water damage Its usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol It is recommended to let the board completely dry before putting in the battery You could have a damaged module in the event that your remote stops working after replacing the battery or updating You can find reprogramming procedures for the majority of vehicles remote key fobs on YouTube or in the owners manual You can also reset your cars computer using the OBDII scanner tool Faulty Receiver Module The key fobs chip is a chip that connects to the cars system If this chip becomes damaged it will no longer transmit or receive signals to the vehicle Dropping the key fob can cause this as could exposure to water If the key fob stops working after exposure to water it could be possible to fix it by cleaning the chip using isopropyl ethanol or electronic cleaner If the key fob doesnt respond to cleaning it is possible that the receiver module has issues and needs to be replaced A damaged receiver module may also cause the remote control key to cease functioning This is typically caused by electromagnetic interference Faulty Electronic Chip The electronic chip inside your key fob plays a vital function in the antitheft security system in your car It transmits a message to the immobiliser in your car to determine if the key is valid If the chip is damaged or damaged your car will not start A malfunctioning chip could be caused by interference signals from other objects bad weather conditions or transmitters on the same frequency close to your car In this scenario an upgrade to the fob will be needed Contacts of the battery may be damaged The battery contacts in a key fob are very delicate and could be damaged by repeated use If theyre bent or damaged the fob will not send any signals to the receiver modules inside the vehicle Modern fobs come with rubber seals that keep out water Submerging them in water even if it is just a light drizzle or splash can damage the electronic chip The key fob contains a chip which communicates with the immobilizer system of the vehicle in order to start it The system utilizes the old red keys in older vehicles or the cryptocoding system found in newer vehicles The chip must be replaced if malfunctioning Problems with 12 Volt Batteries A defective battery can cause the remote to cease working The cars computer may not recognize the remote if this happens Before replacing the battery test it using a the voltmeter to determine its capacity A fully charged battery should display 126 volts If the reading drops significantly its time to change it Put an electrical load for a few seconds on the battery to determine its capacity This will remove 1percent of the charges Then test the voltage again The higher the capacity of the battery and the longer it can maintain its voltage Ideally it should remain at 12 volts or less for several minutes The radio signal is not working properly Radio Signal This is the most frequent cause of a key fob that ceases to send signals to the car The battery can be replaced to fix this problem However it is crucial to buy a new battery that has the same size and voltage as the original Fobs endure a lot of punishment and arent indestructible The battery buttons and the contacts are fragile so they can get bent or broken with the force of A signal can also be affected by other transmitters or objects which use the same frequency A lightcontrol system in your home for instance can interfere with key fobs that use the same bandwidth This could affect the remote control in your car The tool is not working properly OBDII scan tool There are many reasons scanners may not function Certain are more complicated than others The Key Lab enable mechanics to monitor the cars network and run various selftests These are great timesavers but they can be expensive out of the range of most DIYers If your OBD2 scanner wont start make sure you check the voltage at terminal 16 scan tool power and terminal 4 chassis ground If theyre both in good shape the chances are that a fuse is blowing This is the most typical cause of scan tool failure It is usually simple to fix the issue by replacing the fuse that has blown
