Seat Alhambra Key Problems Seat's family MPV jumbo is one of the best in its class in terms of keeping resales value. With a new model available for sale, the family MPV jumbo is better. There are a variety of reasons why the key fob won't perform as it should, including the battery being dead, water damage to the receiver module or signal interference. This article will walk you through the steps needed to get it back to working. Water Damage If your key fob for the seat alhambra withstands a wash cycle or a dip in the ocean or a pool, then it is equipped with a waterproof chip. But, you shouldn't do this often, as prolonged exposure to water increases the risk of the key fob getting damaged. If your key fob stops functioning after exposure to rain or clean tap water, take out the battery and clean the electronic component using a towel. Allow it to dry completely before replacing the battery. 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 you've tried a new battery for a button and the key fob isn't locked or unlocking, it's likely that your receiver module has developed a fault. It's a relatively simple and inexpensive fix. You can remove the 12 volt battery for a couple of minutes (first remove the negative cable and then press the horn numerous times) to drain any remaining power. After that, you can reconnect it in reverse. positive first, then negative. ESP Warning Light - If the ESP symbol blinks, it is normal. It indicates that you are driving on a terrain with poor traction. This could be due to gravel, snow or surface water. If the ESP warning light is continuously flashing, it means there is a problem within the system. It should be detected using an iCarsoft i908 Seat OBD Code Reader, which will give you a specific fault description. Dead Coin Battery A dead coin battery is one of the most frequent causes for the seat alhambra keys to stop working. The key fob is powered by an insignificant button cell battery which keeps it powered. It is recommended to replace it with a replacement that has the same size, voltage, and specification as the original. If you're replacing the battery ensure that you remove all metal clips from the back of the key fob. Also make sure the contacts are free of corrosion. If the key fob has been exposed to water, like soapy or rain, it's recommended that you remove the battery and clean the electronic chip with isopropyl alcohol or a electronic cleaner before putting in the new battery. The chip could be permanently damaged by moisture. If the key fob still not working after replacing the battery, it might be necessary to replace the entire key fob. Faulty Receiver Module If your key fob has stopped working after replacing the battery and it didn't help, or it just stopped working in a sudden manner it is possible that your receiver module could have developed a fault. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob, and changing them into electrical signals that are then utilized by other modules in the car. If the receiver module has suffered a malfunction, it will not respond to any of the commands issued by your remote key fob. In this instance it is necessary for a dealer to reprogramme the key fob and install a new receiver. If the keys are paired but the receiver module has developed a fault you can try to reboot all electronics on board by disconnecting the battery with 12 volts for a short period of time. Then reconnect the battery in reverse order (negative cable first and then positive). This resets all the electronics onboard and will bring them back into operation. Faulty Electronic Chip The key fob contains tiny electronic chips that transmits a signal to the receiver module every time the key is used. If this signal does not match that stored by the car the immobilizer will stop the engine and prevent the vehicle from starting. If the key fob isn't working and you are not able to reprogram it this could be due to a defective chip. The chip in the key fob is not an irreplaceable part of the device and could need to be replaced in order to function again. The best way to do this is to remove the key from its housing and using a pin needle to get into contact with each of the metal clips that hold it. You'll require replacement in the event of damage or damaged by corrosion. Make sure that any replacement batteries have the same voltage, size and specification as the original.
