There are a number of reasons why your key fob may not function properly including dead coin battery, damage to the receiver module, water problems or signal interference. This article will walk you through the steps to fix it.
Water Damage
If your key fob for the seat alhambra withstands an wash cycle or a dip in the ocean or a pool then it's got a waterproof chip. But be careful not to do this often since prolonged exposure to water increases the chance of the key fob getting damaged. If your key fob stops working after exposure to rain or clean tap water, take out the battery and clean the electronic component with a towel. Let it dry completely before replacing the battery. In case of exposure to salt or soapy water it is recommended to clean the chip using isopropyl alcohol or a electronic cleaner before attempting to put the battery back in.
Faulty Receiver Module
If you have tried the battery of a button cell and the key fob doesn't lock or unlock then it's likely that the receiver module has discovered a problem. It's a simple and cheap fix. It is possible to disconnect the battery with 12 volts for a couple of minutes (first remove the negative cable and then press the horn several times) in order to drain any remaining electricity. Then, reconnect it in reverse. Positive cable first and then negative.
ESP Warning Light If the ESP warning light is flashing, this is normal and means that the car is traveling over terrain that has traction issues between the road surface and the tyres isn't optimal, like gravel, snow or a lot of surface water. If the ESP light is always on, it indicates that there is a fault in the system. It can be detected by using an iCarsoft i908 seat OBD code reader kit. It will provide you with a a detailed fault description.
Dead Coin Battery
A dead battery for the coin is among the most common reasons for the keys for the seat to stop working. The key fob is powered by a tiny button-cell battery. It should be replaced with a brand new one that is the same size, voltage and specifications as the original. If you are replacing the battery, be sure to remove all metal clips from the back of the key fob. Also, make sure that the contact points are clean and free of corrosion.
If the key fob has been exposed to water, like soapy or rain, it's recommended that you take the battery off and clean the electronic chip using alcohol or an electronic cleaner before putting in the new battery. The chip could 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 has stopped working after replacing the battery, but it did not function, or stopped working abruptly, your receiver module could have experienced a malfunction. The receiver module receives the radio frequency signals from your key fob's remote and converts them into electrical commands that are then followed by other modules within the car.
If the receiver module is damaged it will not take any commands from your remote key fob. In this situation, a dealer will need to reprogramme the key fob, and also install the new receiver.
The key fob has been sealed with rubber to keep water from leaking into the electronic chip. However, if you submerge your key fob in salted or soapy ocean water, the chip inside could be damaged. If your key fob doesn't function, you can try cleaning the chip using isopropyl or electronic cleaner.
If the keys have been paired but the receiver module has developed a fault, you can try to reboot all the on-board electronics by disconnecting the battery with 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first, then positive). This will reset the on-board electronic and restore their functionality.
Electronic Chip Faulty
The key fob houses tiny electronic chips that transmits a signal to the receiver module each time the key is used. If the signal doesn't coincide with the one stored by the car the immobilizer is able to shut off the engine and stop the vehicle from starting. If the key fob you purchased does not work and you are unable to reprogram it, this could be due to a faulty microchip.
The chip in the key fob is not an indefinite part of the device and might have to be replaced to make it work again. The best method to do this is to remove the key from its housing and using a pin needle to get into contact with each of the metal clips that hold it. You will have to replace them in the event of damage or damaged or corroded. Make sure that the replacement batteries are of the same voltage, size and specifications as the original.
