Seat Alhambra Key Problems Seat's Jumbo MPV family is among the top in its class when it comes down to resales value. With a brand new model on sale the jumbo family MPV is even more impressive. There are a myriad of reasons why the key fob might not work properly, including a dead battery water damage, receiver module issues, or signal interference. This article will walk you through the steps to get it working. Water Damage If your key fob for the seat alhambra withstands an wash cycle, a dip in the ocean or in a pool, then it's equipped with a waterproof chip. But don't do this often, as prolonged exposure to water can increase chances of the key fob becoming damaged. If the key fob stops functioning after exposure to clean water from the tap or rain, simply take out the battery, clean the electronic component with a towel and let it dry completely before putting it back into. If the key fob has been exposed to soapy or salty water, it is recommended that you clean the chip using isopropyl or electronic cleaner. Faulty Receiver Module If the key fob will not lock or unlock after you have replaced the button cell battery It is possible that the receiver module has a fault. It's a fairly simple and cost-effective fix. It is possible to disconnect the 12 volt battery for a couple of minutes (first take off the negative cable, then press the horn several times) to drain any remaining power. After that, you can reconnect it in reverse. Positive cable first, then negative. ESP Warning Light – If the ESP warning light flashes, this is normal and indicates that the car is travelling on terrain where the traction of the road surface and the tyres is not ideal like snow, gravel or lots of surface water. If the ESP warning light is constantly illuminated it indicates that there is an error within the system. This can be diagnosed using a iCarsoft i908 Seat OBD Code Reader kit which will provide you with a specific fault description. Dead Coin Battery A dead coin battery is one of the most frequent causes for the keys for the seat to cease to function. The key fob is powered by a small button-cell battery. Replace it with a brand new battery that has the same voltage, size and specification as the original. If you're replacing your battery, be sure to remove all metal clips from the back of the key fob and make sure the contacts are free of corrosion. If the key fob was exposed to water, like soapy or rain it is recommended to take the battery off and clean the electronic chip with alcohol isopropyl or an electronic cleaner before putting in the new battery. The chip could be permanently damaged by moisture. If the key fob is still not working after replacing the battery, it could be necessary to replace the entire key fob. Faulty Receiver Module If your key fob stopped working after you replaced the battery but it didn't help, or if it just stopped working without notice, then your receiver module could have developed a fault. The receiver module takes the radio frequency signals from your remote keyfob and transforms them into electrical signals that are then followed by other modules inside the car. If the receiver module is defective it will not take any commands from your remote key fob. In this instance, you will need to visit a dealer for reprogramming your key fob as well as a new receiver module. The key fob is sealed with rubber to prevent water from getting into the electronic chip. If you dip the key fob in soapy or salty water, it could damage the chip. If your key fob does not work, you could try cleaning the chip with isopropyl or an electronic cleaner. If the keys are paired, but the receiver module isn't working, you can try to restart all the electronics in the board by disconnecting the battery with 12 volts for a few minutes. Connect seat keys in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality. Electronic Chip Faulty The key fob is outfitted with a small chip that transmits an indication from the key to the receiver module every time the key is used. If the signal does not match the one the car has stored the immobilizer is disabled and prevent the vehicle starting. However, if the fob isn't functioning and you are not able to reprogram it then it could be due to a faulty chip. The chip in the key fob is not a permanent part of the device and could need to be replaced in order to get it working again. This can be accomplished by taking the key fob out of its housing, and then using pins or needles to contact each metal retaining clip. If they are corroded or damaged, you'll require replacement to allow the remote control to function. Make sure that the replacement batteries have the same size, voltage, and specification as the original.
