Water Damage

If your seat alhambra key fob survives washing cycles or a bath in the ocean or pool it's likely to have an incredible waterproof chip, but don't make this a habit as exposure to excessive water increases the risk of the key fob becoming damaged. If your key fob stops functioning after exposure to rain or clean tap water, unplug the battery and clean the electronic component using a paper towel. Allow it to dry completely before replacing the battery. In case of exposure to soapy water or salt, it is recommended to wash the chip with alcohol, isopropyl or electronic cleaner before attempting to put the battery back in.

Faulty Receiver Module

If you've tried the battery of a button cell and the key fob doesn't lock or unlock then it's likely that your receiver module has been faulty. It's a relatively simple and cheap fix. You can disconnect the 12 volts battery for a few minutes (first take off the negative cable, then press the horn a few times) to drain any remaining electricity. Then reconnect it in reverse. Positive cable first, then negative.

Dead Coin Battery

A dead battery for the coin is one of the most frequent causes for the seat alhambra keys to stop working. The key fob is powered by an insignificant button cell battery which keeps it powered. Replace it with a new battery that has the same voltage, size and specification 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 ensure that 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 before installing a new battery. The chip can be permanently damaged by moisture. If the key fob does not work after replacing the battery it might be necessary to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after you replaced the battery and it did not help, or it stopped working completely suddenly, then your receiver module may have developed a fault. The receiver module receives the radio frequency signals from your remote keyfob, and transforms them into electrical signals that are then followed by other modules inside the car.

If the receiver module is damaged it will not take any commands from your remote key fob. In this situation you'll need to go to a dealer for reprogramming of the key fob, and also a new receiver module.

The key fob is sealed with rubber to stop water from entering the electronic chip. However, if you submerge your key fob into soapy water or salty ocean water, the chips inside could be damaged. If your key fob isn't able to function, you can try cleaning the chip with isopropyl or electronic cleaner.

If the keys have been paired but the receiver module has developed a fault you can try rebooting all of the electronics on board by disconnecting the battery with 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first followed by positive). This will reset the on-board electronic and restore their functionality.

Faulty electronic chip

The key fob contains an electronic chip which transmits a signal the receiver module whenever the key is used. If the signal doesn't match the one stored by the car the immobilizer will shut down the engine and prevent the vehicle from starting. If, however, the key fob isn't working, and you can't reprogram it, it could be due a damaged chip.

The chip inside the key fob might need change in order to make it function properly. The most effective method for doing this is by removing the key from its housing and then using a pin needle to contact each of the clips made of metal. If these clips are damaged or damaged, you'll require replacement in order for the remote control to function. Make sure that the replacement batteries have the same voltage, size and specification as the original.
