In case of exposure to salt or soapy water it is recommended that you clean the chip using isopropyl alcohol or a electronic cleaner before attempting to put the battery back in.

Faulty Receiver Module

If you've tried a new button cell battery and the key fob doesn't lock or unlock then it's likely that the receiver module has discovered a problem. The positive side is that this is an easy and affordable fix, you can disconnect the 12 volt battery for several minutes (first take off the negative cable then press the horn button a few times) to eliminate any remaining electricity, and then connect it in reverse order e.g. positive cable first and then negative cable later.

Dead Coin Battery

A dead battery for the coin is among the most frequent causes for the seat alhambra keys to stop working. The key fob is powered by a small button-cell battery. It should be replaced by a new battery that has exactly the same size, voltage, and specification 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 in good condition and free of corrosion.

If the key fob was exposed to water (such as soapy tap water) it is recommended that you remove and clean the chip using an electronic cleaner or isopropyl ethanol before installing a brand new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob doesn't work after replacing the battery it may be necessary for you to replace the key fob.

Faulty Receiver Module

If your key fob stopped working after replacing the battery but it didn't function, or stopped working abruptly your receiver module might have encountered a problem. The receiver module is able to receive radio frequency signals from your key fob's remote and converts them into electrical commands which are then acted upon by other modules inside the car.

If the receiver module has developed a fault, it will not respond to any of the commands issued by your remote key fob. In this instance you will require a dealer to reprogramme the key fob and install the new receiver.

The key fob is fitted with rubber seals that block water from entering the electronic chip inside. If you dip the key fob into soapy or salty water, it may damage the chips. If your key fob doesn't work, you could try cleaning the chip with isopropyl or an electronic cleaner.

If the keys are successfully paired, but your receiver module isn't working it is possible to restart all the electronics in the board by disconnecting the 12-volt battery for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.

A malfunctioning electronic chip

The key fob is equipped with an electronic chip that transmits a message to the receiver module every time the key is used. If the signal isn't in line with the one the car has stored the immobilizer will turn off and prevent the vehicle from starting. If the key fob doesn't function and you are not able to reprogram it, this could be due to a malfunctioning microchip.

The chip inside the key fob could need to be altered to allow it to function again. The best way to do this is to remove the key from its housing and then using a pin or needle to get into contact with each of the metal retaining clips. You'll have to replace them if they are damaged or corrosion-prone. Make sure that the replacement batteries are the same size, voltage and specifications as the original one.
