There are many reasons that the key fob may not function properly including dead coin battery or damage to the receiver module, water issues, or signal interference. This article will walk you through the steps to get it working.

Water Damage

If your key fob for the seat alhambra survives an wash cycle or dip in the ocean or a pool, then it's equipped with a waterproof chip. But, you shouldn't do this often, as prolonged exposure to water can increase the likelihood of the key fob becoming damaged. If the key fob stops functioning after exposure to clean tap water or rain, then just remove the battery, clean the electronic component with paper towel and let it dry completely before putting it back into. If the battery is exposed to soapy or salty water it is recommended to wash the chip with isopropyl alcohol or electronic cleaner prior to trying to put the battery back in.

Faulty Receiver Module

If the key fob does not lock or unlock after having replaced the button cell battery it could be that the receiver module has an issue. The positive side is that this is a relatively simple and inexpensive repair, you can just remove the battery 12 volts for a few minutes (first take off the negative cable then press the horn button several times) to eliminate any remaining electricity, and then connect it in reverse order e.g. positive first, then negative cable later.

ESP Warning Light – If the ESP symbol blinks, it is normal. It means that you are driving on terrain that has poor traction. This could be due to gravel, snow or surface water. If the ESP warning light remains blinking, it indicates that there is a fault within the system. It is best to be detected using an iCarsoft i908 seat key OBD Code Reader kit which will provide you with a specific fault description.

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 with a new one that has 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 has been exposed water, such as soapy or rain, it's recommended that you take the battery off and clean the electronic chip with isopropyl alcohol or an electronic cleaner before putting in the new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob still not working after replacing the battery, it could be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped working after you replaced the battery and it did not help, or if it just stopped working out of the blue the receiver module may have developed a fault. The receiver module is able to receive radio frequency signals from your remote keyfob, and transforms them into electrical signals which are then acted upon by other modules in the car.

If the receiver module is damaged and is not able to take any commands from your remote key fob. In this case it is necessary for a dealer to reprogramme your key fob as well as install an additional receiver.

The key fob comes with rubber seals that prevent water from entering the chip inside. If you immerse the key fob in salty or soapy water, it could damage the chip. If your key fob doesn't work, try cleaning the chip with isopropyl or electronic cleaner.

If the keys have been paired but the receiver module has developed a fault you may try to restart all of the onboard electronics by disconnecting the battery that is 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic and restore their functionality.

Electronic Chip Faulty

The key fob has tiny electronic chips that sends a signal to the receiver module whenever the key is used. If the signal received does not match the one recorded by the car the immobilizer is able to shut off the engine and stop the vehicle from beginning. If the key fob doesn't work and you are unable to reprogram it, it could be because of a faulty microchip.

The chip in the key fob is not an irreplaceable part of the device and could need to be replaced in order to get it to work again. The most effective method for doing this is by removing the key from its housing and using a pin needle to make contact with each of the metal clips that hold it. You'll have to replace them in the event that they have been damaged or corroded. Make sure that the replacement batteries have the same size, voltage, and specification as the original one.
