Faulty Receiver Module


If you have tried a new button cell battery and the key fob does not lock or unlock, it's likely that the receiver module has been faulty. It's a fairly simple and cheap fix. You can disconnect the 12 volts battery for a few minutes (first remove negative cable, then press the horn numerous times) to eliminate any remaining electricity. Then reconnect it in reverse. Positive cable first, then negative.

ESP Warning Light If the ESP warning light is flashing, this is normal and means that the vehicle is driving on terrain where the traction between the road surface and tyres isn't optimal, like gravel, snow or lots of surface water. If the ESP warning light is constantly shining, it is a sign that there is an error within the system.

Dead Coin Battery

A dead coin battery is one of the most frequent causes for the seat alhambra keys to cease to function. 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. If you're replacing the battery, be sure to remove all metal retaining clips from the back of the key fob and ensure that the contacts are clean and free of corrosion.

If the key fob was exposed to water, like soapy or rain it is recommended to take the battery off and clean the electronic chip with isopropyl alcohol or an electronic cleaner prior to inserting the new battery. The chip can be permanently damaged by water. 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 has stopped working after you replaced the battery but it did not help, or it stopped working completely suddenly, then your receiver module may have developed an issue. The receiver module is responsible for capturing the radio frequency signals transmitted by your remote key fob and converting them into electrical commands which are then processed by other modules within the car.

If the receiver module is damaged, it will not accept any commands from your remote key fob. In this instance it is necessary for a dealer to reprogramme your key fob, and also install the new receiver.

The key fob has rubber seals that prevent water from getting into the electronic chip inside. If you immerse your key fob into the ocean's salty or soapy water, the chip inside may be damaged. If your key fob doesn't work, you can try cleaning the chip using isopropyl or electronic cleaner.

If the keys have been linked, but the receiver module isn't working then you can restart all the electronics that are on board by disconnecting the battery with 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality.

A malfunctioning electronic chip

The key fob comes with a chip that transmits the signal from the key to the receiver module every time the key is used. If the signal received does not match the one recorded by the car the immobilizer will stop the engine and stop the vehicle from beginning. If the key fob you purchased does not function and you are not able to reprogram it, this could be because of an issue with the microchip.

The chip inside the key fob isn't an irreplaceable part of the device and could need to be replaced in order to get it working again. This can be done by taking the key fob away from its case, and using pins or needles to contact each metal retaining clip. If these are corroded or damaged, you'll require replacement in order for the remote control to function. Make sure that any replacement batteries are the same size, voltage and specifications as the original one.
