Water Damage
If your key fob for the seat alhambra survives a wash cycle or a dip in an water or a pool, it has a waterproof chip. But, you shouldn't do this often, as prolonged exposure to water increases the chance of the key fob becoming damaged.

Let it dry completely before replacing the battery. If the key fob was exposed to soapy or salty water and salty water, it is recommended you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If you've tried a new battery for a button and the key fob cannot be locked or unlocked, it's likely the receiver module has developed a fault. The good thing is that this is an easy and affordable fix, you can simply remove the battery 12 volts for about a couple of minutes (first take off the negative cable, then press the horn button several times) to eliminate any remaining electric current, then reconnect it in reverse order e.g. Positive cable first, then negative.
ESP Warning Light If the ESP warning light flashes, it is normal and indicates that the vehicle is driving on terrains where the traction between the road surface and the tyres aren't as good, such as snow, gravel or a lot of surface water. If the ESP warning light is constantly flashing, it means there is a problem within the system. It is best to be diagnosed using a iCarsoft i908 Seat OBD Code Reader, which will provide a precise 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 has tiny button cell batteries which keeps it powered. It is recommended to replace it with a brand new one that is identical in size, voltage and specifications as the original. If you're replacing the battery ensure that you remove all metal clips from the back of the key fob. Also make sure that the contacts are free of corrosion.
If the key fob has been exposed to water, such as soapy or rain, 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 can be permanently damaged. 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 has stopped working after replacing the battery, but it didn't help, or if it suddenly stopped working suddenly, then your receiver module might have developed an issue. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands that are then processed by other modules within the car.
If the receiver module is faulty and is not able to take any commands from your remote key fob. In this case, you will need to go to a dealer for reprogramming your key fob as well as a new receiver module.
The key fob is fitted with rubber seals to prevent water from getting into the chip inside. If you immerse the key fob in salty or soapy water, it may damage the chips. You can attempt to clean the chip by rub it with isopropyl alcohol or electronic cleaner, however should your key fob doesn't work after doing this, you'll have to purchase a new one.
If the keys are connected but the receiver module has developed a fault, you may try to restart all electronics on board by disconnecting the battery with 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset all electronic components onboard and restore their functionality.
A malfunctioning electronic chip
The key fob is equipped with a tiny chip which transmits a signal from the key to the receiver module every time the key is used. If the signal received does not match the one recorded by the car the immobilizer will stop the engine and stop the vehicle from beginning. If the key fob doesn't work and you are unable to reprogram it, it could be due to an incompatible microchip.
The chip inside the key fob may have to be altered to allow it to function again. This can be accomplished by getting the key fob removed from its housing, and then using pins or needles to make contact with each metal retaining clip. You will need to replace these in the event that they have been damaged or damaged or corroded. Make sure the replacement batteries are of the same size, voltage and specifications as the original.
