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 should be replaced with a replacement that is the same size, voltage and specifications as the original. When replacing the battery on the key fob, remove all metal clips and ensure that the contacts of the key fob are clean and free of corrosion.
If the key fob was exposed to water (such as soapy or rain tap water), it is recommended that you remove and clean the chip with an electronic cleaner or isopropyl ethanol before installing a brand new battery. The chip may be permanently damaged by moisture. If the key fob does not work after replacing the battery it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery, but it didn't help, or it stopped working completely out of the blue it is possible that your receiver module may have developed a fault. The receiver module is responsible for capturing the radio frequency signals transmitted by your remote key fob and converting them into electrical commands which are then processed by other modules in your car.

The key fob is fitted with rubber seals that block water from getting into the electronic chip inside. If you immerse your key fob in the ocean's salty or soapy water, the chips inside may be damaged. You can try cleaning the chip by rub it with isopropyl alcohol or electronic cleaner, but in the event that your key fob does not work after this, you'll have to purchase a new one.
If the keys have been successfully paired, but your receiver module is malfunctioning You can try to restart all the electronics that are on board by disconnecting the battery at 12 volts for few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.
A malfunctioning electronic chip
The key fob is equipped with an electronic chip that transmits a message to the receiver module whenever the key is used. If the signal received does not match the one stored by the car the immobilizer will stop the engine and prevent the vehicle from beginning. If the key fob you purchased does not work and you aren't able to reprogram it, this could be due to an issue with the microchip.
The chip inside the key fob could need change to allow it to function again. The most effective method for doing this is to remove the key from its housing and then using a pin needle to connect with each of the metal clips that hold it. You'll have to replace them in the event of damage or damaged or corroded. Make sure that the replacement batteries have the same size, voltage and specification as the original.
