There are a myriad of reasons that the key fob may not function properly, such as a dead coin battery, water damage, receiver module problems or signal interference. This article will walk you through the steps to make sure it works.
Water Damage
If your key fob for the seat alhambra survives a wash cycle or a dip in the water or a pool, it's equipped with a waterproof chip. However, don't do it often because prolonged exposure to water increases the chance that the key fob will be damaged. If your key fob stops functioning after being exposed to rain or clean tap water, take out the battery and clean the electronic component using a towel. Let it dry completely before replacing the battery. If the key fob was exposed to soapy or salty water it is recommended you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after you have replaced the button cell battery it could be that the receiver module is suffering from a fault. The good news is that this is a relatively simple and inexpensive repair, you can just remove the battery 12 volts for a few minutes (first remove 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 and then negative.

ESP Warning Light If the ESP warning light is flashing, this is normal and means that the car is driving over terrain in which the traction between the road surface and tyres isn't optimal, 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 by using an iCarsoft i908 seat OBD code reader kit. It will give you the full description of the problem.
Dead Coin Battery
One of the most common reasons for the seat alhambra keys to stop functioning is a dead coin battery. The key fob is powered by a tiny button-cell battery. Replace it with a brand new battery that is the same size, voltage and specifications as the original. When replacing the battery on the key fob, remove the metal clips and make sure that the contacts on the key fob are clean and corrosion-free.
If the key fob has been exposed water, like soapy or rain it is recommended to remove the battery and clean the electronic chip with isopropyl alcohol or an electronic cleaner prior to inserting the new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob doesn't work after replacing the battery, it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it did not work, or if it stopped working in a sudden manner the receiver module may be experiencing a problem. The receiver module is responsible for receiving the radio frequency signals that are sent by your remote key fob and convert them into electrical signals that are then utilized by other modules in your car.
If the receiver module is damaged it will not be able to accept any commands from your remote key fob. In this situation, you will have to visit a dealer to reprogram the key fob, and also a new receiver module.
The key fob is sealed with rubber to prevent water from leaking into the electronic chip. If you immerse the key fob into salty or soapy water it may damage the chips. If your key fob isn't able to work, try cleaning the chip using isopropyl or electronic cleaner.
If the keys are in a pair but the receiver module has developed a fault you can try restarting all electronics on board by removing the 12 volt battery for a few minutes. Then reconnect the battery in reverse order (negative cable first before positive). This will reset all the on-board electronics and should bring them back into operation.
Electronic Chip Faulty
The key fob has a small electronic chip which transmits a signal the receiver module every time the key is used. If the signal received does not coincide with the one stored by the car, the immobilizer will disable the engine and stop the vehicle from starting. If the key fob you purchased does not function and you are not able to reprogram it, it could be due to a faulty microchip.
The chip in the key fob may need change in order to make it function properly. The best way to do this is to remove the key from its housing and then using a pin or needle to make contact with each of the metal retaining clips. If the clips are corroded, or damaged, you'll require replacement in order for the remote control to function. Make sure that the replacement batteries have the same size, voltage, and specifications as the original one.
