Water Damage

If your seat alhambra key fob can withstand the wash cycle or a bath in the pool or ocean it's likely to have an incredible waterproof chip, but do not use it regularly because exposure to water in excess increases the chance of the key fob becoming damaged.

Faulty Receiver Module

If you've tried a new button cell battery and the key fob still does not lock or unlock, it is likely that the receiver module has developed a fault. The good news is that it is an easy and inexpensive repair, you can simply remove the battery 12 volts for just a few minutes (first take off the negative cable and press the horn button several times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive first, then negative.

ESP Warning Light – If the ESP symbol is flashing, this is normal. It is a sign that you are driving on terrain that has poor traction. This could be caused by snow, gravel or surface water.

Dead Coin Battery

A dead battery for the coin is among the most frequent causes for the seat alhambra keys to cease to function. The key fob comes with an insignificant button cell battery that is able to keep it powered. It should be replaced with a new one that is identical in size, voltage, and specification as the original. If you're replacing the battery be sure to remove all metal clips from the back of the key fob. Also, ensure that the contacts are free of corrosion.

If the key fob was exposed to water (such as rain or soapy tap water), it is recommended that you remove and clean the chip with an electronic cleaner or isopropyl alcohol before installing a brand new battery. The chip could be permanently damaged by water. If the key fob still doesn't function 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 didn't perform, or stopped working in a sudden manner your receiver module might have experienced a malfunction. The receiver module is able to receive radio frequency signals from your remote keyfob and converts them into electrical commands which are then acted upon by other modules in 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 your key fob and new receiver module.

The key fob has rubber seals that stop water from entering the electronic chip inside. If you submerge the key fob in salty or soapy water it could cause damage to the chip. You can try cleaning the chip by rub it with isopropyl alcohol or electronic cleaner, however in the event that your key fob does not work after this, you'll have to buy a new one.

If the keys have been paired, but the receiver module is faulty then you can restart all of the electronics on board by disconnecting the battery at 12 volts for few minutes. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset the on-board electronic circuits and restore their functionality.

Faulty electronic chip

The key fob is outfitted with a tiny chip which transmits the signal from the key to the receiver module each time the key is used. If the signal does not match the one the car has stored the immobilizer will be disabled and stop the vehicle from starting. However, if the fob isn't functioning and you are not able to reprogram it the issue could be due to a faulty chip.

The chip in the key fob might need change to allow it to function again. The best method to do this is to remove the key from its housing and using a pin or needle to make contact with each of the clips made of metal. If the clips are corroded, or damaged, you'll require replacement seat key to allow the remote control to function. Make sure any replacement batteries have the same voltage, size and specifications as the original.
