Seat Alhambra Key Problems
Seat's MPV jumbo family is among the top in its class when it comes down to resales values. And with a new generation model available it's even more impressive.
There are a myriad of reasons why your key fob may not function correctly, including dead battery, water damage, receiver module problems or signal interference. This article will walk you through the steps necessary to fix it.
Water Damage
If your seat alhambra key fob survives the wash cycle or a bath in the ocean or pool then it is likely to have an incredible waterproof chip, but do not use it regularly because prolonged exposure to water increases the chance of the key fob becoming damaged. If the key fob ceases to working after exposure to clean tap water or rain, then just remove the battery, clean the electronic component with a paper towel and allow it to dry completely before putting the battery back in. If the key fob has been exposed to salty or soapy water it is recommended you clean the chip with isopropyl or an 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. The good news is that this is a relatively simple and cost-effective fix. You can just disconnect the battery for a few minutes (first take off the negative cable then press the horn button multiple times) to drain any residual electricity and then reconnect it in reverse order e.g. Positive cable first and then negative.

If the ESP light is constantly on, it is a sign that there is a problem in the system. It can be detected by using an iCarsoft i908 seat OBD code reader kit. It will provide the full description of the problem.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not working is a dead coin battery. The key fob is powered by a small button-cell battery. It is recommended to replace it with a replacement that has the same voltage, size, and specification 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 ensure that the contacts are clean and 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 isopropyl ethanol prior to installing a new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob doesn't function after replacing the battery it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob has stopped working after replacing the battery and it did not help, or it just stopped working in a sudden manner it is possible that your receiver module may have developed a fault. The receiver module receives the radio frequency signals from your remote keyfob and converts them into electrical commands which are then used by other modules inside the car.
If the receiver module has developed a fault that prevents it from responding to any of the commands sent by your remote key fob. In this case you'll be required to visit a service for reprogramming your key fob as well as a new receiver module.
The key fob has been sealed by rubber to block water from entering the electronic chip. If you immerse your key fob in soapy water or salty ocean water, the chips inside may be damaged. If your key fob doesn't work, you can try cleaning the chip with isopropyl or an electronic cleaner.
If the keys are successfully paired, but your receiver module is faulty You can try to restart all the electronics in the board by disconnecting the battery at 12 volts for couple of minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuits and restore their functionality.
Faulty electronic chip
The key fob is outfitted with a chip that transmits a signal from the key to the receiver module every time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer will turn off and stop the car from starting. If, however, the key fob isn't working and you are not able to reprogram it, it could be due to a faulty chip.
The chip inside the key fob is not an irreplaceable part of the device and may need to be replaced to make it work again. The best way to do this is to remove the key from its housing and then using a pin or needle to get into contact with each of the metal clips that hold it. If they are corroded or damaged, you'll need to replace them in order for the remote control to work. Make sure that the replacement batteries have the same size, voltage and specification as the original.
