Water Damage
If your key fob for the seat Alhambra is able to withstand washing cycles or a dip in the ocean or a pool, then it's equipped with a waterproof chip.

The good news is that this is a fairly easy and affordable fix, you can simply remove the battery 12 volts for just a few minutes (first remove the negative cable, then press the horn button multiple times) to eliminate any remaining electrical current and then reconnect it in reverse order e.g. positive cable first, then negative cable later.

Dead Coin Battery
A dead coin battery is among the most frequent reasons for the keys for the seat to stop working. The key fob is powered by a tiny button-cell battery. It is recommended to replace it with a new one that is identical in size, voltage, and specification as the original. If you're replacing your battery, ensure that you remove all metal retaining clips from the back of the key fob. Also, make sure that the contacts are 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 before putting in the new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob does not work after replacing the battery it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it did not work, or stopped working suddenly the receiver module could be experiencing a problem. The receiver module takes the radio frequency signals from your remote keyfob and transforms them into electrical signals that are then processed by other modules inside the car.
If the receiver module is damaged it will not take any commands from your remote key fob. In this instance you'll have to visit a dealer to reprogramme your key fob and new receiver module.
The key fob is encased by rubber to block water from getting inside the electronic chip. If you dip the key fob into salty or soapy water it may damage the chips. If your key fob does not work, try cleaning the chip with isopropyl or electronic cleaner.
If the keys are connected, but the receiver module is malfunctioning then you can restart all the electronics that are on board by disconnecting the 12-volt battery for a couple of minutes. Then reconnect the battery in reverse order (negative cable first followed by positive). This will reset the onboard electronic and restore their functionality.
Electronic Chip Faulty
The key fob houses a small electronic chip that transmits a message to the receiver module every time the key is used. If the signal doesn't coincide with the one stored by the car, the immobilizer will disable the engine and stop the vehicle from beginning. However, if the key fob is not working and you are unable to reprogram it this could be due to a defective chip.
The chip inside the key fob is not a permanent part of the device and may need to be replaced to function again. The most effective method for doing this is to remove the key from its housing and using a pin needle to connect with each of the retaining clips made of steel. You will need to replace these in the event that they have been damaged or corrosion-prone. Make sure that the replacement batteries are the same size, voltage, and specification as the original.
