Fiat Panda Key Fob Replacement Fiat Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors and start the engine The fob might stop working for a variety of reasons A dead coin battery is the most common reason for malfunctioning keys Other causes include water damage as well as a defective module and interference signals Dead Coin Battery Replace the battery if your key fob is dead Make use of a new button battery that is the same voltage size and specifications like the previous one If the key fob has been exposed to water for example a splash of rain or salt water on the beach its going to 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 an issue with the receiver module or an internal electronic chip In these cases it is possible to reprogramme the key fob using an OBDII scanner might aid Water Damage If your key fob has gotten a bath in the pool or puddle or walked to the washing machine you might have some water damage Its generally possible to get it working by taking the batteries off and cleaning the circuit board with ruby alcohol Its best to allow the fob to dry completely before installing a new battery If your key fob isnt working even after replacing the battery and changing the program you could have a defective receiver module You can find reprogramming procedures for most remote key fobs on YouTube or in the owners guide You can also reset your computer of your car using the OBDII scanner tool Faulty Receiver Module The key fob contains a chip that communicates with the vehicles system This chip will stop sending and receiving signals to the car when it is damaged This could be due to dropping the key fob or by water exposure If the key fob stopped functioning after exposure to water it may be possible to repair it by cleaning the chip with isopropyl alcohol or an electronic cleaner If the key fob does not respond following cleaning there is a good chance that the component is damaged and will require to be replaced A faulty receiver module can also cause the remote control key to stop working This usually happens due to electromagnetic interference Faulty Electronic Chip The 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 tell it that the key is valid The car wont start in the event that the chip is damaged A damaged chip could be caused by interference signals from other objects bad weather conditions or transmitters on the same frequency as your car In this scenario the replacement fob will be required Faulty battery contacts The battery contacts inside the key fob are delicate and may be damaged by repeated use If theyre bent or broken the fob wont send any signals to the receiver modules in the car Modern fobs are made with rubber seals that keep out water Immersing fiat 500 key fob in water even if it is just small splash or drizzle could damage the electronic chip The key fob comes with an electronic chip that communicates with the immobilizer system of the vehicle to begin it The system relies on cryptocoding systems in modern vehicles or the red key system used in older ones If this chip is faulty it must be replaced A faulty 12 Volt battery A faulty battery can cause the key fob to cease to function The cars system will not recognize the remote when this occurs Before replacing the battery test it by using a an voltmeter to gauge its capacity A fully charged battery should read 126 volts If the reading drops significantly the time is now to replace it To test a batterys capacity test the batterys capacity by placing an electrical load on it for a few minutes This will take off about 1 of the charge on the surface Then you can measure the voltage The longer a battery can hold its voltage more effectively the greater its capacity Ideal is that it stays close to 12 volts during several minutes Radio Signal Faulty Radio Signal This is the most common reason for a key fob that stops sending signals to the car This problem can be solved by replacing the battery However it is crucial to select a replacement battery that is the same voltage and size as the original one The buttons are not impervious to destruction and can be damaged by a lot Contacts on batteries and buttons can be damaged through rough handling Other transmitters or objects operating on the same frequency can also interfere with the signal For instance a light control panel that is near your home could transmit interference using the same frequency that key fobs utilize This could affect your cars remote control Faulty OBDII Scan Tool There are many reasons scanners may not perform Certain are more complicated than others Professional scan tools allow mechanics to observe the cars networks and run a variety of selftests They can be huge time savers but they are also extremely expensive out of the budget of most DIYers If your OBD2 scan tool wont power on check the voltage at the terminals 16 scantool power and 4 chassis earth If theyre all fine a fuse may have blown This is the most common cause of scan tool failure It is typically easy to fix the issue by replacing the blown fuse
