Seat Alhambra Key Problems
Seat's jumbo MPV family is among the top models in its class when it comes down to resale values. And with a brand new model now on sale, it's better than ever.
There are many reasons the key fob won't perform as it should, including an unresponsive coin battery or water damage to the receiver module, or signal interference. This article will guide you through the steps needed to get it back to working.
Water Damage
If your key fob for the seat alhambra withstands an wash cycle or a dip in the ocean or a pool, then it's got a waterproof chip. But be careful not to do this often, as prolonged exposure to water increases the risk of the key fob being damaged. If the key fob ceases to working after exposure to clean water from the tap or rain, just take out the battery, clean the electronic component with a paper towel and let it dry completely before putting it back into. If the key fob was exposed to soapy or salty water, it is recommended that you clean the chip with isopropyl or electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after having replaced the battery for the button, it is possible that the receiver module is suffering from a fault. It's a fairly simple and cost-effective fix. You can remove the 12 volt battery for a couple of minutes (first take off the negative cable, then press the horn numerous times) to remove any remaining power. After that, you can reconnect it in reverse. Positive cable first followed by negative.
ESP Warning Light If the ESP warning light is flashing, this is normal and signifies that the car is traveling through terrain in which the traction between the road surface and the tyres isn't ideal, such as gravel, snow or a lot of surface water. If the ESP light is constantly flashing, it is a sign there is a fault in the system. It can be detected with a iCarsoft i908 seat OBD code reader kit.

TheKeyLab of the most frequent reasons for the seat alhambra keys to stop working is a dead coin battery. The key fob contains a tiny button cell battery which keeps it powered. It is recommended to replace it by a new battery with exactly the same size, voltage and specifications as the original. If you are replacing the battery, ensure that you remove all metal clips from the back of the key fob. Also, ensure that the contacts are free of corrosion.
If the key fob was exposed to water (such as soapy tap water) it is recommended that you remove and clean the chip using an electronic cleaner or isopropylethanol before installing a brand new battery. The chip can be permanently damaged by water. If the key fob isn't working 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 it stopped working completely in a sudden manner, then your receiver module may 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 within the car.
If the receiver module has developed a fault that prevents it from responding to any of the commands received by your remote key fob. In this instance you will require a dealer to reprogramme your key fob and install an additional receiver.
The key fob is fitted with rubber seals that block water from entering the chip inside. However, if you submerge your key fob in the ocean's salty or soapy water, the chip inside may be damaged. You can try cleaning the chip by using isopropyl Alcohol to rub it or electronic cleaner, however If your key fob isn't working after all this, then you'll need to buy a new one.
If the keys are paired but the receiver module has developed a fault, you can try restarting all of the electronics on board by disconnecting the 12 volt battery for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.
Electronic Chip Faulty
The key fob contains a small electronic chip that sends a signal to the receiver module every time the key is used. If this signal does not coincide with the one stored by the car, the immobilizer will disable the engine and prevent the vehicle from beginning. If the key fob won't work and you aren't able to reprogram it, this could be due to an incompatible microchip.
The chip in the key fob isn't an irreplaceable part of the device and could need to be replaced to get it working again. The best way to do this is by removing the key from its housing and then using a pin needle to connect with each of the metal retaining clips. If the clips are corroded, or broken, you will need to replace them to allow the remote control to function. Make sure that any replacement batteries have the same voltage, size and specification as the original.
