If your key fob for the seat alhambra withstands the wash cycle or a dip in the water or a pool, it's got a waterproof chip. However, don't do it often because prolonged exposure to water increases the chance of the key fob being damaged. If your key fob stops working after exposure to rain or clean tap water, you should remove the battery and wipe the electronic component using a towel. Dry it completely before replacing the battery. In the event of exposure to soapy water or salt, it is recommended to wash the chip using isopropyl alcohol or a electronic cleaner before attempting to put the battery back in.

Faulty Receiver Module

If the key fob will not lock or unlock after you have replaced the button cell battery it is possible that the receiver module has a fault. The positive side is that this is a simple and affordable fix, you can disconnect the battery for about a couple of minutes (first take off the negative cable and press the horn button multiple times) to drain any residual electricity, and then connect it in reverse order e.g. positive first, then negative cable later.

ESP Warning Light - If the ESP warning light is flashing, this is normal and means that the car is driving over terrain that has traction issues between the road surface and the tyres isn't optimal, like snow, gravel or a lot of surface water. If the ESP warning light remains shining, it is a sign that there is a problem within the system and should be identified using an iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description.

Dead Coin Battery

One of the most frequent reasons for the seat alhambra keys to stop functioning is a dead coin battery. The key fob is powered by an insignificant button cell battery which keeps it powered. Replace it with a new battery that is the same size, voltage, and specifications as the original. If you are replacing the battery, ensure that you remove all metal retaining clips from the back of the key fob. You should also make sure the contacts are free of corrosion.

If the key fob was exposed to water (such as soapy tap water), it is recommended to remove and clean the chip with an electronic cleaner or isopropylethanol prior to installing a new battery. The chip could be permanently damaged by moisture. If the key fob is still not working after replacing the battery, it might be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped working after you replaced the battery and it did not help, or if it suddenly stopped working out of the blue it is possible that your receiver module may have developed a fault. The receiver module is responsible for capturing the radio frequency signals sent by your remote key fob, and changing them into electrical signals that are then acted on by other modules in the car.

If the receiver module is faulty it will not take any commands from your remote key fob. In this instance you will require a dealer to reprogram your key fob and install an entirely new receiver.

The key fob features rubber seals that stop water from getting into the chip inside. If you immerse your key fob into soapy water or salty ocean water, the chip inside may be damaged. If your key fob does not work, you could 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 rebooting all the on-board electronics by disconnecting the battery at 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first, then positive). This will reset the onboard electronic and restore their functionality.

A malfunctioning electronic chip

The key fob is equipped with a chip that transmits the 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 will turn off and prevent the vehicle from starting. If, however, the key fob isn't functioning and you are unable to reprogram it, it could be due to a defective chip.

The chip inside the key fob may need to be changed in order to get it working again. The best method to do this is to remove the key from its housing and using a pin needle to make contact with each of the metal retaining clips. You will have to replace them in the event that they have been damaged or damaged by corrosion. Make sure that any replacement batteries are of the same voltage, size and specification as the original one.
