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 should be replaced with a new one 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 on the key fob are clean and free of corrosion.
If the key fob has been exposed to water, like rain or soapy water, it's recommended that you remove the battery and clean the electronic chip with alcohol or an electronic cleaner prior to inserting the new battery. The chip could be permanently damaged by water. If the key fob still not working after replacing the battery, it could be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery but it didn't work, or suddenly stopped working the receiver module may have encountered a problem. The receiver module is able to receive radio frequency signals from your remote keyfob and converts them into electrical commands that are then processed by other modules within the car.

The key fob features rubber seals that block water from getting into the chip inside. However, if you submerge your key fob in soapy water or salty ocean water, the chip inside may be damaged. You can try to clean the chip by rubbing it with isopropyl alcohol or electronic cleaner, however should your key fob doesn't work after doing this, then you'll need to purchase a replacement.
If the keys are paired but the receiver module has developed a fault, you can try to reboot all of the electronics on board by disconnecting the battery with 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset all the on-board electronics and should restore their functionality.
Electronic chip that is malfunctioning
The key fob houses an electronic chip which transmits a signal the receiver module when the key is used. If the signal doesn't match the one that the car has stored the immobilizer will be disabled and stop the vehicle from starting. If the key fob isn't working, and you are not able to reprogram it, it could be due to a defective chip.
The chip in the key fob may have to be altered to allow it to function again. The most effective method for doing this is by removing the key from its housing and then using a pin needle to contact each of the metal retaining clips. If these are corroded or damaged, you'll need to replace them to allow the remote control to work. Make sure that the replacement batteries are of the same size, voltage and specifications as the original.
