There are a myriad of reasons the key fob might not function properly, such as the battery being dead damage to the receiver module, or signal interference. This article will guide you through the steps needed to get it back in working order.
Water Damage
If your seat alhambra key fob is able to withstand the wash cycle or a bath in the pool or ocean it's likely to have an incredible waterproof chip, but do not make it a habit because exposure to water in excess increases the risk of the key fob being damaged. If the key fob ceases to functioning after exposure to clean tap water or rain, just take out the battery, wipe the electronic component with paper towel and let it dry completely before putting the battery back into. 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 you've tried a new button cell battery and the key fob still cannot be locked or unlocked, it's likely that the receiver module has developed a fault. The positive side is that this is a simple and inexpensive repair, you can just disconnect the battery for about a couple of minutes (first remove the negative cable then press the horn button numerous times) to remove any remaining electricity and then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light – If the ESP symbol blinks, it is normal. It means that you are driving over terrain with poor traction. This could be caused by snow, gravel or surface water. If the ESP warning light continues to be shining, it is a sign that there is an error within the system and should be detected using an iCarsoft i908 Seat OBD Code Reader kit that will give you a specific 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 is powered by a tiny button-cell battery. It should be replaced with a replacement with the same voltage, size 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 the contacts are free of corrosion.
If the key fob was exposed to water (such as soapy or rain tap water), it is recommended that you remove and clean the chip using an electronic cleaner or isopropylethanol before installing a brand new battery. seat keys may be permanently damaged by water. If the key fob is 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 function, or stopped working in a sudden manner the receiver module could have developed a problem. The receiver module receives the radio frequency signals from the remote keyfob and transforms them into electrical signals that are then followed by other modules inside the car.

If the receiver module is defective, it will not accept any commands from your remote key fob. In this case, you will be required to visit a service to reprogram the key fob, and also a new receiver module.
The key fob comes with rubber seals that stop water from getting into the chip inside. If you submerge the key fob into salty or soapy water it could damage the chip. If your key fob does not work, you could try cleaning the chip using isopropyl or electronic cleaner.
If the keys are successfully paired, but your receiver module is not working, you can try to restart all the electronics in the board by disconnecting the battery at 12 volts for few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.
Faulty Electronic Chip
The key fob is equipped with a small chip that transmits a signal from the key to the receiver module every time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer is disabled and prevent the vehicle from starting. However, if the key fob isn't working and you can't reprogram it the issue could be due to a faulty chip.
The chip inside the key fob is not an indefinite part of the device and may need to be replaced to make it work again. The best way to do this is by removing the key from its housing and then using a pin or needle to contact each of the metal retaining clips. If these are corroded or broken, you will have to replace them in order for the remote control to work. Make sure that the replacement batteries are of the same size, voltage, and specification as the original.
