What's The Most Common Fiat 500 Keys Debate Isn't As Black And White As You May Think Fiat Panda Key Fob Replacement Fiat Panda keyfobs are equipped with a transponder that sends an indication from the fob to the car to unlock doors or start the motor. The fob can stop functioning due to a variety reasons. A dead coin battery is the most frequent reason for a key fob malfunction. Other causes include water damage malfunctioning receiver modules and signal interference. Dead Coin Battery Replace the battery if the key fob has failed. Make use of a button cell battery with the same voltage, size and specifications as the previous one. If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it needs to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can help. If the key fob has not been exposed to water but still does not work it could be a problem with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner can help. Water Damage If your key fob has taken an immersion in the puddle or pool, or taken a trip through the washing machine, it could have some water damage. It's usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before putting in 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 reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool. Faulty Receiver Module The key fob has the chip that communicates the vehicle's system. If this chip becomes damaged, it will no longer be able to send or receive signals to the vehicle. www.g28carkeys.co.uk can be caused by dropping the key fob or through exposure to water. If your key fob has stopped working due to exposure to water and you are unable to fix it by attempting to clean the chip with electronic cleaner or isopropyl alcohol. If the key fob does not respond after cleaning it, then it is likely that the receiver module is not functioning properly and must be replaced. A faulty receiver can also cause the key to not work. This is usually caused by electromagnetic interference. Faulty Electronic Chip The electronic chip in your key fob plays a vital function in the anti-theft security system in your car. It transmits a message the immobiliser in your car to inform it whether the key is legitimate. Your car won't start when the chip is damaged. A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency in close proximity to your car. In this scenario, a new fob will be needed. Faulty battery contacts The battery contacts on a key fob can be damaged through heavy use. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules in the car. Modern fobs are constructed with rubber seals to keep out water. A splash of water or a light rain is acceptable however, submerging them in saltwater could damage the chip's electronic components. The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to begin it. This system utilizes cryptocoding systems in modern vehicles, or the old red key system for older ones. If the chip is damaged it must be replaced. A faulty 12 Volt battery A malfunctioning battery could cause the key fob to cease to function. When this happens the car's computer will not recognize that the remote is within the vehicle. Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops dramatically the time is now to replace it. To determine the capacity of a battery, place an electrical load on it for a couple of minutes. This will take away 1percent of the surface charges. After that, take the voltage again. The longer a battery can keep its voltage steady more effectively, the greater its capacity. It should be at or near 12 volts for several minutes. Problems with Radio Signal This is the main reason for a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this problem. But, it is essential to buy a new battery that has the same voltage and size as the original. Fobs can take a lot punishment, and aren't impervious to destruction. The battery buttons and the contacts are fragile and are susceptible to being bent or damaged from excessive use. Other objects or transmitters using the same frequency can disrupt a signal. A light-control system in your home, for instance, may interfere with key fobs which use the same bandwidth. This can affect the remote control of your car. Incorrect OBDII Scan Tool There are a variety of reasons why scanners may not perform. Some are more complex than others. Professional scan tools enable mechanics to examine the car's systems and conduct a variety self-tests. These tools can save you a lot of time, but they are costly and are out of reach for most DIYers. If your OBD2 scanner isn't turning on Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse has blown. This is among the most common reasons for failure of the scanner. The simple fix is usually to replace the fuse which has blown.
