Dead Coin Battery One of the most common reasons for the seat alhambra keys to stop working is a dead coin battery. The key fob is powered by a tiny button-cell battery. Replace it with a brand new battery that has the same size, voltage, and specifications as the original. If you are replacing the battery, ensure that you remove all metal clips from the back of the key fob. Also make sure the contacts are clean and free of corrosion. If the key fob was exposed to water, like rain or soapy water, it's recommended that you take the battery off and clean the electronic chip using isopropyl alcohol or a electronic cleaner prior to putting in the new battery.

Faulty Receiver Module If your key fob stopped working after you replaced the battery, but it did not help, or it just stopped working suddenly, then your receiver module could have developed a fault.

In this case you'll be required to visit a service to reprogramme the key fob, and also a new receiver module. The key fob is fitted with rubber seals that stop water from getting into the electronic chip inside. If you dip the key fob into salty or soapy water, it could cause damage to the chip. If seat leon key fob replacement won't work, try cleaning the chip with isopropyl or electronic cleaner. If the keys have been paired, but the receiver module is faulty, you can try to restart all of the electronics on board by disconnecting the battery at 12 volts for few minutes.

Faulty Electronic Chip The key fob contains an electronic chip which transmits a signal the receiver module whenever the key is used. If this signal does not match that stored by the car the immobilizer will stop the engine and prevent the vehicle from beginning. If the key fob won't work and you aren't able to reprogram it, it could be due to an issue with the microchip. The chip in the key fob may need to be altered in order to make it function properly. This can be done by removing the key fob from its housing, and then using a needle or pin to touch each metal clip. You will need to replace these when they're damaged or corroded.
