There are a number of reasons why your key fob might not function properly including dead coin battery, water damage, receiver module issues or signal interference. seat leon key programming will walk you through the steps to get it working again.
Water Damage
If your key fob for the seat alhambra survives washing cycles or a dip in an ocean or a pool then it is equipped with a waterproof chip. However, don't do it often as excessive exposure to water increases the likelihood of the key fob becoming damaged. If the key fob ceases to working after exposure to clean water from the tap or rain then simply remove the battery, clean the electronic component with a paper towel and let it dry completely before putting it back into. In case of exposure to soapy or salty water it is recommended to wash the chip using isopropyl alcohol or a electronic cleaner prior to attempting to put the battery back in.
Faulty Receiver Module
If you have tried an entirely new battery for your button and the key fob does not lock or unlock, it's likely that the receiver module has found a fault. The good news is that it is a simple and affordable fix, you can disconnect the battery for several minutes (first take off the negative cable and then press the horn button a few times) to eliminate any remaining electricity, and then connect it in reverse order e.g. Positive first followed by negative.
ESP Warning Light If the ESP warning symbol flashes this is normal and signifies that the car is traveling on terrains where the traction between the road surface and tyres is not ideal like gravel, snow or lots of surface water. If the ESP light is always on, it indicates that there is a flaw in the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit. It will provide a detailed fault description.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra key not working is a dead coin battery. The key fob is powered by a tiny button-cell battery. Replace it with a brand new battery with the same voltage, size and specification as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts of the key fob are clean and free of corrosion.
If the key fob has been exposed to water, such as soapy or rain it is recommended to remove the battery and clean the electronic chip with isopropyl alcohol or a electronic cleaner prior to inserting the new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob still not working after replacing the battery, it may be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery, but it did not function, or stopped working abruptly the receiver module may have experienced a malfunction. The receiver module is responsible for capturing the radio frequency signals that are sent by your remote key fob, and transform them into electrical commands which are then processed by other modules in your car.
If the receiver module is defective it will not take any commands from your remote key fob. In this scenario, a dealer will need to reprogram your key fob and install an additional receiver.
The key fob has rubber seals that stop water from entering the chip inside. If you immerse your key fob into soapy water or salty ocean water, the chip inside may be damaged. It is possible to clean the chip by rub it with isopropyl alcohol or electronic cleaner, however in the event that your key fob isn't working after this, then you'll need to purchase a new one.
If the keys have been linked, but the receiver module is not working, you can try to restart all of the electronics on board by disconnecting the 12-volt battery for a couple of minutes. Connect the battery in reverse (negative cable to positive first). This resets all the on-board electronics and should bring them back into operation.
A malfunctioning electronic chip
The key fob is equipped with a small chip that transmits the signal from the key to the receiver module every time the key is used. If the signal doesn't coincide with the one stored by the car, the immobilizer will disable the engine and prevent the vehicle from starting. If the key fob doesn't function and you are not able to reprogram it, it could be due to a malfunctioning microchip.
The chip inside the key fob is not permanent to the device, and might need to be replaced to function again. The best method to do this is to remove the key from its housing and then using a pin or needle to connect with each of the retaining clips made of steel. You'll need to replace these when they're damaged or damaged by corrosion. Make sure that any replacement batteries are of the same voltage, size and specifications as the original.
