There are many reasons the key fob won't work as expected, including an inoperative coin battery or damage to the receiver module or signal interference. This article will guide you through the steps to get it back in working order.
Water Damage
If your key fob for the seat alhambra can withstand the wash cycle, a dip in the ocean or a pool, then it has a waterproof chip. But be careful not to do this often as excessive exposure to water can increase the chance that the key fob will be damaged. If your key fob stops functioning after exposure to rain or clean tap water, remove the battery and wipe the electronic component using a paper towel. Let it dry completely before replacing the battery. 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 you've tried the battery of a button cell and the key fob cannot be locked or unlocked, it is likely that the receiver module has developed a fault. The positive side is that this is an easy and affordable fix, you can disconnect the 12 volt battery for a few minutes (first take off the negative cable, then press the horn button several times) to remove any remaining electricity and then reconnect it in reverse order e.g. positive first, then negative cable later.
ESP Warning Light - If the ESP symbol is illuminated, this is normal. It is a sign that you are driving on a terrain that has poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly flashing, it is a sign there is a problem in the system. This can be identified with a iCarsoft i908 seat OBD code reader kit.

Dead Coin Battery
A dead battery for the coin is one of the most frequent reasons for the keys for the seat to cease to function. The key fob comes with tiny button cell batteries that keeps it running. It is recommended to replace it with a replacement that has identical in size, voltage, and specification as the original. If you're replacing your battery, ensure that you remove all metal clips from the back of the key fob. Also, make sure that the contact points are free of corrosion.
If the key fob has been exposed water, like rain or soapy water, it's recommended that you take the battery off and clean the electronic chip using alcohol or an electronic cleaner before putting in the new battery.

If your key fob stopped functioning after replacing the battery but it did not function, or stopped working abruptly the receiver module could have developed a problem. The receiver module is responsible for capturing the radio frequency signals transmitted by your remote key fob, and convert them into electrical signals that are then acted on by other modules in the car.
If the receiver module has developed a fault it will not respond to any of the commands sent by your remote key fob. In this instance you'll need to visit a dealer for reprogramming of the key fob, and also a new receiver module.
The key fob features rubber seals that prevent water from getting into the chip inside. If you dip the key fob in soapy or salty water, it could damage the chip. If your key fob does not work, you can 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 of the onboard electronics by removing the battery that is 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset all the electronics onboard and will restore their functionality.
Electronic Chip Faulty
The key fob is fitted with a tiny chip that transmits a signal from the key to the receiver module each time the key is used. If this signal does not match that stored by the car, the immobilizer will disable the engine and prevent the vehicle from beginning. However, if the key fob isn't working and you cannot reprogram it the issue could be due to a faulty chip.
The chip inside the key fob isn't permanent to the device and may need to be replaced in order to make it work again. This can be accomplished by taking the key fob out of its case, and using a needle or pin to touch each metal clip. If the clips are corroded, or broken, you will have to replace them in order for the remote control to function. Make sure that the replacement batteries are the same voltage, size and specifications as the original one.
