Seat Alhambra Key Problems Seat's family MPV jumbo is among the best in class when it comes to conserving resale value. With a new generation model available, it's better than ever. There are many reasons why your key fob may not function properly, such as a dead coin battery damage to the receiver module, water problems or signal interference. This article will guide you through the steps to get it working. seat keys If your seat alhambra key fob is able to withstand the wash cycle or a bath in the ocean or pool it's likely to have an amazing waterproof chip but do not make it a habit because exposure to water in excess increases the chance of the key fob being damaged. If your key fob stops working after exposure to rain or clean tap water, take out the battery and wipe the electronic component using a paper towel. Let it dry completely before replacing the battery. If the key fob has been exposed to salty or soapy water and salty water, it is recommended you clean the chip using isopropyl or an electronic cleaner. Faulty Receiver Module If you've tried an entirely new battery for your button and the key fob doesn't lock or unlock then it's likely that your receiver module has developed a fault. The good thing is that this is a simple and cost-effective fix. You can simply disconnect the battery for just a few minutes (first take off the negative cable and then press the horn button numerous times) to drain any residual electric current, then reconnect it in reverse order e.g. positive cable first, then negative. ESP Warning Light – If the ESP warning light flashes, it is normal and signifies that the car is travelling through terrain where the traction between the road surface and the tyres is not ideal like snow, gravel or lots of surface water. If the ESP warning light is constantly blinking, it indicates that there is a fault within the system. It is best to be detected with a iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description. Dead Coin Battery One of the most frequent reasons for the seat alhambra key not working is a dead battery. The key fob is powered by a tiny button-cell battery. It is recommended to replace it with a replacement with identical in size, voltage and specifications as the original. If you're replacing the battery ensure that you remove all metal retaining clips from the back of the key fob. Also, make sure that the contacts are free of corrosion. If the key fob was exposed to water (such as rain or soapy tap water), it is recommended that you remove and clean the chip with an electronic cleaner or isopropyl ethanol before installing a new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob is still not working after replacing the battery, it might be necessary to replace the entire key fob. Faulty Receiver Module If your key fob stopped functioning after replacing the battery but it did not work, or stopped working abruptly the receiver module may be experiencing a problem. 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 within 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 scenario the dealer will have to reprogramme your key fob and install the new receiver. The key fob is fitted with rubber seals to prevent water from getting into the chip inside. If you submerge the key fob in salty or soapy water it could cause damage to the chip. It is possible to clean the chip by using isopropyl Alcohol to rub it or electronic cleaner, but should your key fob does not work after this, then you'll need to purchase a new one. If the keys have been paired but the receiver module has developed a fault, you can try to reboot all the on-board electronics by disconnecting the battery that is 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset all electronics onboard and will bring them back into operation. Faulty Electronic Chip The key fob is equipped with an electronic chip that sends a signal to the receiver module when the key is used. If the signal doesn't coincide with the one stored by the car, the immobilizer will disable the engine and stop the vehicle from starting. If the key fob isn't working and you are unable to reprogram it this could be due to a defective chip. The chip inside the key fob may have to be changed in order to get it working again. The best way to do this is to remove the key from its housing and using a pin or needle to connect with each of the retaining clips made of steel. If these clips are damaged or broken, you will have to replace them in order for the remote control to function. Make sure that any replacement batteries are of the same size, voltage and specification as the original.

Some owners have reported problems with the automatic climate control system. It could malfunction and become stuck in a particular setting. Additionally, the infotainment feature has also been known to malfunction and freeze screens.
