Water Damage

If your key fob for the seat alhambra withstands the wash cycle, a dip in the water or a pool, it is equipped with a waterproof chip.

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

Faulty Receiver Module

The positive side is that this is a fairly easy and affordable fix, you can disconnect the battery for several minutes (first remove the negative cable and then press the horn button a few times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive cable first, then negative.

Dead Coin Battery

One of the most frequent reasons for the Seat key alhambra key not working is a dead coin battery. The key fob is powered by a small button-cell battery. Replace it with a new battery that is the same voltage, size and specification as the original. If you're replacing the battery, be sure to remove all metal retaining clips from the back of the key fob and make sure the contacts are free of corrosion.

If the key fob was exposed to water (such as rain or soapy tap water) it is recommended to remove and clean the chip with an electronic cleaner or isopropyl ethanol before installing a new battery. The chip may be permanently damaged by water. If the key fob 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 functioning after replacing the battery but it did not work, or suddenly stopped working, your receiver module could have encountered a problem. The receiver module receives the radio frequency signals from your key fob's remote and converts them into electrical commands which are then acted upon by other modules within the car.

If the receiver module has developed a fault and is unable to respond to any of the commands sent by your remote key fob. In this situation it is necessary for a dealer to reprogramme your key fob and install the new receiver.

If the keys have been paired but the receiver module has developed a fault, you may try to restart all the on-board electronics by disconnecting the 12 volt battery for a few minutes. Then reconnect the battery in reverse order (negative cable first, then positive). This will reset all the electronic components onboard and restore their functionality.

Electronic chip that is malfunctioning

The key fob is equipped with tiny electronic chips that sends a signal to the receiver module when the key is used. If the signal isn't in line with the one that the car has stored, the immobilizer will disable and stop the vehicle from starting. If the key fob doesn't work and you aren't able to reprogram it, this could be due to a faulty microchip.

The chip inside the key fob might need to be replaced to allow it to function again. This can be done by taking the key seat fob out of its housing, and then using a needle or pin to contact each metal retaining clip. You will require replacement when they're damaged or corroded. Make sure any replacement seat key batteries have the same size, voltage, and specification as the original.
