Water Damage

If the key fob has been exposed to salty or soapy water it is recommended that you clean the chip using isopropyl or an electronic cleaner.

Faulty Receiver Module

If the key fob will not lock or unlock after you've replaced the battery in the button cell it is possible that the receiver module is suffering from an issue. The good news is that it is a simple and affordable fix, you can just disconnect the 12 volt battery for just a few minutes (first take off the negative cable and press the horn button numerous times) to remove any remaining electricity, and then connect it in reverse order e.g. Positive first, then negative.

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

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 which keeps it powered. Replace it with a brand new battery that has the exact size, voltage, and specifications as the original. When replacing the battery on the key fob remove all metal clips and ensure that the contacts of the key fob are clean and free of corrosion.

If the key fob has been exposed water, like rain or soapy water it is recommended to remove the battery and clean the electronic chip with alcohol or an electronic cleaner before putting in the new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob still does not work after replacing the battery, it might be necessary to replace the key fob.

Faulty Receiver Module


If your key fob was not working after replacing the battery but it didn't perform, or stopped working suddenly your receiver module might have encountered a problem. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands which are then used by other modules within the car.

If the receiver module has a problem, it will not accept any commands from your remote key fob. In this case the dealer will have to reprogramme your key fob as well as install a new receiver.

The key fob is covered with rubber to prevent water from getting inside the electronic chip. If you submerge the key fob in salty or soapy water, it may damage the chips. If your key fob does not function, you can try cleaning the chip with isopropyl or electronic cleaner.

If the keys are linked, but the receiver module is not working, you can try to restart all the electronics that are on board by disconnecting the battery that is 12 volts for a couple of minutes. Then reconnect the battery in reverse order (negative cable first and then positive). This will reset the on-board electronic and restore their functionality.

Faulty electronic chip

The key fob comes with a chip that transmits an indication from the key to the receiver module each time the key is used. If the signal doesn't match that stored by the car, the immobilizer will disable the engine and stop the vehicle from beginning. If the key fob won't work and you aren't able to reprogram it, this could be because of an issue with the microchip.

The chip inside the key fob may need to be changed in order to make it function properly. The most effective method for doing this is to remove the key from its housing and using a pin needle to contact each of the metal clips that hold it. If the clips are corroded, or damaged, you'll have to replace them in order for the remote control to function. Make sure any replacement batteries are of the same voltage, size, and specification as the original.
