There are a myriad of reasons why the key fob could not function properly including dead coin battery water damage, receiver module issues or signal interference. This article will guide you through the steps to get it working.
Water Damage
If your seat alhambra key fob survives washing cycles or a bath in the pool or ocean then it is likely to have an amazing waterproof chip but don't make this a habit because exposure to water in excess increases the risk of the key fob becoming damaged. If the key fob stops working after exposure to clean tap water or rain, simply take out the battery, wipe the electronic component with a paper towel and allow it to dry completely before putting it back into. If the key fob has been exposed to salty or soapy water it is recommended you clean the chip with isopropyl or electronic cleaner.
Faulty Receiver Module
If you've tried the battery of a button cell and the key fob does not lock or unlock, it is likely that the receiver module has found a fault. The good news is that it is a fairly easy repair that is inexpensive, you can disconnect the battery for about a couple of minutes (first remove the negative cable, then press the horn button a few times) to eliminate any remaining electricity and then reconnect it in reverse order e.g. positive cable first and then negative.
ESP Warning Light - If the ESP warning light flashes, this is normal and signifies that the car is traveling on terrain that has traction issues between the road surface and the tyres is not ideal such as snow, gravel or a lot of surface water. If the ESP warning light is constantly illuminated it indicates that there is a problem within the system. It is best to be detected with a iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not functioning is a dead coin battery. The key fob is powered by an insignificant button cell battery that keeps it powered. Replace it with a new battery with the same dimensions, voltage and specs as the original. If you're replacing the battery be sure to remove all metal clips from the back of the key fob. Also make sure that the contacts are clean and free of corrosion.
If the key fob has been exposed water, such as soapy or rain it is recommended to take the battery off and clean the electronic chip using isopropyl alcohol or a electronic cleaner prior to installing the new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob still isn't working after replacing the battery it could be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery, but it did not work, or stopped working in a sudden manner, your receiver module could have developed a problem. The receiver module takes the radio frequency signals from your remote keyfob, and converts them into electrical commands that are then processed by other modules inside the car.
If the receiver module is damaged it will not be able to accept any commands from your remote key fob. In this case you'll need to go to a dealer to reprogram your key fob and new receiver module.
The key fob is fitted with rubber seals to prevent water from getting into the electronic chip inside. However, if you submerge your key fob in salty or soapy water, the chips inside could be damaged. If your key fob isn't able to work, try cleaning the chip using isopropyl or electronic cleaner.
If the keys have been successfully paired, but your receiver module is malfunctioning then you can restart all of the electronics on board by disconnecting the battery that is 12 volts for a couple of minutes. Connect seat alhambra key programming in reverse (negative cable to positive first). This resets all the on-board electronics and should restore their functionality.
Electronic Chip Faulty
The key fob is equipped with a chip that transmits an indication from the key to the receiver module each time the key is used. If the signal received does not match the one stored by the car, the immobilizer will disable the engine and stop the vehicle from starting. If the key fob isn't working and you cannot reprogram it this could be due a damaged chip.
The chip in the key fob isn't permanent to the device, and might need to be replaced in order to make it work again. The best method to do this is by removing the key from its housing and using a pin needle to get into contact with each of the metal clips that hold it. You'll require replacement when they're damaged or corroded. Make sure that the replacement batteries are of the same voltage, size and specifications as the original one.
