However, do not make it a habit since exposure to excessive water increases the risk of the key fob being damaged.

If the key fob has been exposed to salty or soapy water it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after you've replaced the battery in the button cell It is possible that the receiver module has an issue. The good news is that it is a relatively simple and inexpensive repair, you can remove the battery 12 volts for about a couple of minutes (first take off the negative cable and then press the horn button several times) to eliminate any remaining electrical current and then reconnect it in reverse order e.g. positive first, then negative cable later.
ESP Warning Light - If the ESP symbol is flashing, this is normal. It means that you are driving on terrain with poor traction. This could be caused by snow, gravel or surface water. If the ESP light is constantly flashing, it is a sign there is a problem in the system. It is possible to identify the problem by using an iCarsoft i908 seat OBD code reader kit.

Dead Coin Battery
One of the most frequent reasons for the seat alhambra key to stop working is a dead coin battery. The key fob contains an insignificant button cell battery that keeps it running. It should be replaced with a replacement that is the same voltage, size 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 in good condition and free of corrosion.

The chip can be permanently damaged by water. If the key fob still not working after replacing the battery, it may 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 stopped working abruptly the receiver module may have developed a problem. The receiver module receives the radio frequency signals from your remote keyfob and converts them into electrical commands which are then acted upon by other modules within the car.
If the receiver module has developed a fault, it will not respond to any of the commands issued by your remote key fob. In this case you'll have to visit a dealer for reprogramming of your key fob and a new receiver module.
The key fob is encased by rubber to block water from getting inside the electronic chip. If you immerse your key fob into the ocean's salty or soapy water, the chips inside may be damaged. If your key fob doesn't work, you can try cleaning the chip with isopropyl or electronic cleaner.
If the keys have been linked, but the receiver module is faulty, you can try to restart all the electronics in the board by disconnecting the battery with 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first before positive). This resets all the electronics onboard and will bring them back to their original functionality.
Electronic chip that is malfunctioning
The key fob is equipped with a small electronic chip that sends a signal to the receiver module every time the key is used. If this signal does not match that stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from beginning. If, however, the key fob isn't working and you cannot reprogram it the issue could be due a damaged chip.
The chip in the key fob could need to be altered to allow it to function again. The best way to do this is to remove the key from its housing and using a pin or needle to connect with each of the metal clips that hold it. You will require replacement in the event that they have been damaged or damaged or corroded. Make sure that the replacement batteries are the same size, voltage, and specifications as the original.
