The good news is that it is a fairly easy and affordable fix, you can simply remove the battery 12 volts for a few minutes (first take off the negative cable, then press the horn button numerous times) to eliminate any remaining electric current, then reconnect it in reverse order e.g. Positive cable first and then negative.

Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop working is a dead battery. The key fob has an insignificant button cell battery that is able to keep it powered.

The chip may 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 and it did not help, or if it suddenly stopped working in a sudden manner it is possible that your receiver module could have developed an issue. The receiver module takes the radio frequency signals from your key fob's remote and transforms them into electrical signals which are then acted upon by other modules within the car.
If the receiver module is faulty it will not take any commands from your remote key fob. In this situation, a dealer will need to reprogramme your key fob, and also install the new receiver.
The key fob is sealed with rubber to prevent water from leaking into the electronic chip. If you dip the key fob in soapy or salty water, it could damage the chip. If your key fob doesn't function, you can try cleaning the chip using isopropyl or electronic cleaner.
If the keys have been successfully paired, but your receiver module is malfunctioning You can try to restart all the electronics in the board by disconnecting the battery with 12 volts for a couple of minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.
Electronic Chip Faulty
The key fob is outfitted with a tiny chip that transmits a signal from the key to the receiver module every time the key is used. If the signal does not match the one the car has stored the immobilizer will turn off and prevent the vehicle from starting. However, if the key fob is not working and you can't reprogram it this could be due to a faulty chip.
The chip in the key fob may have to be replaced in order to get it working again. The best way to do this is by removing the key from its housing and using a pin needle to contact each of the metal retaining clips. You will need to replace these in the event of damage or corrosion-prone. Make sure that any replacement batteries have the same size, voltage and specifications as the original.
