Fiat Panda Key Fob Replacement Fiat Panda key fobs contain a transponder chip which sends a signal to your car to open the doors and start the engine fiat 500 replacement key might stop working due to a variety reasons The most commonly cited reason for key fob failure is the battery of the coin is dead Other causes include water damages or a malfunctioning module and interference signals Dead Coin Battery Replace the battery in case your key fob has died Use a button cell that has the same voltage size and specification as your old one If the key fob has been exposed to water like a splash of rain or salt water on the beach its going to need to be cleaned before it can be used again The trick is to use the paper towel and soak it in isopropyl or electronic cleaner If the key fob doesnt working despite not being exposed water it could be due to a problem in the receiver module or internal electronic chip Reprogramming the keyfob through an OBDII scan could help in these instances Water Damage There could be water damage if your key fob was submerged in a pool puddle or washing machine It is usually possible to be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol Its best to let the fob dry completely prior to installing a new battery If your key fob stopped working even after replacing the battery and reprogramming it you may have a problem with the receiver module There are instructions for reprogramming most vehicles remote keys on YouTube or consult the owners manual You can also reset your computer of your car using the OBDII scanner tool Faulty Receiver Module The key fobs chip is an electronic chip that communicates with the vehicles system This chip will stop sending and receiving signals to the car if damaged This could be due to dropping the key fob or due to exposure to water If the key fob has stopped working after exposure to water it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner If the key fob does not respond to cleaning it is possible that the component has an issue and should be replaced A damaged receiver module may also cause the remote control key to stop working This is usually due to electromagnetic interference Faulty Electronic Chip The electronic chip in your key fob is a crucial element of the antitheft device in your vehicle It sends out a signal the immobiliser unit of the vehicle to determine whether or not the key is legitimate If the chip is damaged or broken the car wont start A defective chip can be caused by interference signals from other objects or weather conditions that are bad or transmitters operating on the same frequency in close proximity to your car In this instance youll require an entirely new key fob Contacts for the battery that are damaged The battery contacts of the fobs key can be damaged due to heavy use If they are damaged or bent the fob will not send any signals to the receiver modules in the car Modern fobs are made with rubber seals that keep out water Immersing them in water even if its just the slightest splash or drizzle could harm the chips electronic circuit The key fob contains chips that communicate with the vehicles immobilizer system in order to begin it The system is based on the old red keys that were used in older vehicles or the crypto coding system in the latest vehicles If the chip is defective it will have to be replaced Problems with 12 Volt Batteries A faulty battery may cause the key fob to function When this occurs the cars computer cannot recognize that the remote is in the vehicle 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 it is time to replace the battery Place an electrical load for a short time on the battery to check its capacity This will take away 1percent of the charges Then you can measure the voltage again The longer the battery can hold its voltage and the higher its capacity The ideal is to keep it close to 12 volts during several minutes Faulty Radio Signal This is the most typical reason behind a key fob that stops sending signals to the car The battery could be replaced to fix this issue However it is crucial to select a replacement battery that is the same voltage and size as the original one Fobs arent indestructible and can take a lot Contacts and buttons on batteries can be damaged by rough handling The signal could also be disrupted by other objects or transmitters that operate on the same frequency For instance a lightcontrol panel in your home could send interference on the same frequency that key fobs utilize This can interfere with the remote control of your car Afflicted OBDII Scan Tool There are a number of reasons why a scanner could not function Some are more complex than others Professional scan tools let mechanics to look over the cars network and run various selftests These tools can save time but they are costly and out of reach for the majority of DIYers If your OBD2 scanner doesnt work Check the voltage on terminal 16 scan tool power and terminal 4 chassis ground If these are OK its possible that a fuse has been blown This is among the most common reasons for failure of the scanner The easiest solution is to replace the fuse which has blown
