It is a relatively easy and cost-effective fix.

Dead Coin Battery
One of the most frequent reasons for the seat alhambra key not functioning is a dead coin battery. The key fob contains a small button cell battery that keeps it powered. It is recommended to replace it with a replacement that has exactly the same size, voltage and specifications as the original. If you're replacing the battery be sure to remove all metal retaining clips from the back of the key fob. You should 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 to remove and clean the chip with an electronic cleaner or isopropyl alcohol before installing a new battery. The chip can be permanently damaged by moisture. 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 if it stopped working suddenly the receiver module could be experiencing a problem. The receiver module is responsible for absorbing the radio frequency signals that are sent by your remote key fob and converting them into electrical commands which are then processed by other modules in your car.
If the receiver module is defective it will not be able to accept any commands from your remote key fob. In this situation the dealer will have to reprogramme the key fob, and also install an entirely new receiver.
The key fob features rubber seals that block water from getting into the chip inside. If you dip the key fob in salty or soapy water, it may damage the chips. If your key fob isn't able to work, you can try cleaning the chip with isopropyl or an electronic cleaner.
If the keys have been successfully paired, but your receiver module is not working it is possible to restart all the electronics in the board by disconnecting the battery that is 12 volts for a couple of minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality.
Electronic Chip Faulty
The key fob is fitted with a small chip that transmits an indication from the key to the receiver module each time the key is used. If the signal received does not coincide with the one stored by the car the immobilizer will stop the engine and prevent the vehicle from beginning. If the key fob won't function and you are not able to reprogram it, this could be due to an incompatible microchip.
The chip inside the key fob could need to be replaced to allow it to function again. This can be accomplished by taking the key fob out of its housing, and then using a needle or pin to make contact with each metal retaining clip. If these clips are damaged or broken, you will require replacement to allow the remote control to work. Make sure that the replacement batteries have the same size, voltage, and specification as the original.
