Seat Alhambra Key Problems Seat's jumbo MPV range is among the top in its class when it comes to resales values. And with a new generation model on sale, it's even better. There are many reasons the key fob could not perform as it should, including the battery being dead or damage to the receiver module or signal interference. This article will guide you through the steps necessary to get it working. Water Damage If your seat alhambra key fob is able to withstand the wash cycle or a bath in the ocean or pool then it probably has an amazing waterproof chip. However, don't make this a habit since exposure to excessive water increases the chance of the key fob becoming damaged. If the key fob stops working after exposure to clean tap water or rain, simply take out the battery, wipe the electronic component with a towel and let it dry completely before putting the battery back in. If the key fob was exposed to salty or soapy water it is recommended you clean the chip using isopropyl or an electronic cleaner. seat key cover If you have tried the battery of a button cell and the key fob still does not lock or unlock, it is likely that the receiver module has been faulty. It's a fairly simple and affordable fix. You can disconnect the battery with 12 volts for a couple of minutes (first take off the negative cable, then press the horn several times) in order to drain any remaining power. After that, you can reconnect it in reverse. positive cable first then negative cable later. ESP Warning Light – If the ESP warning symbol flashes this is normal and signifies that the car is traveling over terrain where the traction between the road surface and tyres isn't ideal, such as gravel, snow or lots of surface water. If the ESP warning light is continuously flashing, it means there is a glitch in the system. This can be diagnosed using a iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description. Dead Coin Battery A dead battery for the coin is one of the most common causes for the keys for the seat to stop working. The key fob is powered by a small button-cell battery. It should be replaced with a new one with the same voltage, size, and specification as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts of the key fob are in good condition and free of corrosion. If the key fob has been exposed to water, such as soapy or rain it is recommended to remove the battery and clean the electronic chip with isopropyl alcohol or an electronic cleaner before putting in the new battery. The chip may be permanently damaged by moisture. If the key fob still does not work after replacing the battery, it could be necessary to replace the key fob. Faulty Receiver Module If your key fob has stopped working after replacing the battery but it didn't help, or if it just stopped working out of the blue, then your receiver module may have developed a fault. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob, and convert them into electrical signals which are then processed by other modules in your car. If the receiver module has suffered a malfunction it will not respond to any of the commands sent by your remote key fob. In this scenario, you will be required to visit a service for reprogramming of your key fob and new receiver module. The key fob is covered with rubber to keep water from getting into the electronic chip. However, if you submerge the key fob in soapy water or salty ocean water, the chip inside may be damaged. If your key fob doesn't function, you can try cleaning the chip with isopropyl or electronic cleaner. If the keys are paired but the receiver module has developed a fault you may try to restart all electronics on board by disconnecting the battery at 12 volts for a short period of time. Then reconnect the battery in reverse order (negative cable first before positive). This resets all the on-board electronics and should bring them back to their original functionality. Electronic Chip Faulty The key fob is fitted with a tiny chip which transmits an indication from the key to the receiver module every time the key is used. If the signal received does not coincide with the one stored by the car the immobilizer is able to shut off the engine and stop the vehicle from beginning. However, if the key fob isn't working, and you cannot reprogram it the issue could be due to a malfunctioning chip. The chip inside the key fob may have to be altered in order to get it working again. This can be accomplished by taking the key fob out of its case, and using pins or needles to make contact with each metal retaining clip. You will have to replace them in the event that they have been damaged or damaged or corroded. Make sure the replacement batteries have the same voltage, size, and specification as the original.
