If the key fob has been exposed to soapy or salty water it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after having replaced the button cell battery It is possible that the receiver module is suffering from an issue. The good thing is that this is an easy and inexpensive repair, you can simply disconnect the 12 volt battery for just a few minutes (first take off the negative cable and then press the horn button multiple times) to drain any residual electricity and then reconnect it in reverse order e.g. Positive cable first followed by negative.
ESP Warning Light - If the ESP warning light is flashing, this is normal and signifies that the vehicle is driving on terrains where the traction of the road surface and the tyres isn't ideal, like gravel, snow or a lot of surface water. If the ESP light is always on, it is a sign that there is a flaw in the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit. It will give you a detailed fault description.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra key to stop functioning is a dead coin battery. The key fob is powered by a small button-cell battery. seat key replacement is recommended to replace it with a brand new one with the same voltage, size, and specification as the original. If you're replacing the battery, ensure that you remove all metal clips from the back of the key fob. You should also make sure that the contacts are clean and free of corrosion.
If the key fob was exposed to water (such as rain or soapy tap water), it is recommended to remove and clean the chip using an electronic cleaner or isopropyl ethanol before installing a brand new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob still not working after replacing the battery, it might be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob has stopped working after replacing the battery but it did not help, or it suddenly stopped working without notice it is possible that your receiver module could have developed a fault. The receiver module receives the radio frequency signals from your remote keyfob and transforms them into electrical signals that are then processed by other modules within the car.
If the receiver module has suffered a malfunction it will not respond to any of the commands sent by your remote key fob. In this scenario it is necessary for a dealer to reprogramme the key fob as well as install a new receiver.
The key fob is encased with rubber to stop water from entering the electronic chip. If you dip the key fob into salted or soapy water it could cause damage to the chip. If your key fob isn't able to work, try cleaning the chip with isopropyl or an electronic cleaner.
If the keys have been paired but the receiver module has developed a fault you may try to restart all of the electronics on board by removing the battery that is 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset all the electronic components on board and restore their functionality.
Faulty Electronic Chip
The key fob has an electronic chip that sends a signal to the receiver module when the key is used. If the signal doesn't match the one the car has stored the immobilizer will be disabled and prevent the vehicle starting. If the key fob you purchased does not work and you aren't able to reprogram it, this could be due to a faulty microchip.

The best method to do this is by removing the key from its housing and then using a pin needle to make contact with each of the clips made of metal. You will need to replace these in the event of damage or corrosion-prone. Make sure that any replacement batteries are the same size, voltage, and specification as the original one.
