Faulty Receiver Module

Dead Coin Battery
One of the most common reasons for the seat alhambra key to stop working is a dead coin battery. The key fob is powered by a tiny button-cell battery.

Faulty Receiver Module
If your key fob was not working after replacing the battery, but it did not function, or stopped working in a sudden manner the receiver module may be experiencing a problem.

Electronic Chip Faulty
The key fob comes with a small chip that transmits an indication from the key to the receiver module every time the key is used. If the signal received does not match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. If the key fob you purchased does not function and you are not able to reprogram it, this could be because of a faulty microchip.

The best way to do this is to remove the key from its housing and using a pin or needle to contact each of the metal retaining clips. If they are corroded or broken, you will require replacement to allow the remote control to work. Make sure that any replacement batteries have the same size, voltage and specifications as the original.
