There are many reasons why the key fob might not work properly, including a dead battery damage to the receiver module, water problems or signal interference. This article will walk you through the steps needed to get it working again.
Water Damage
If your seat alhambra keyfob is able to survive a wash cycle or a bath in the pool or ocean it's likely to have an amazing waterproof chip but do not use it regularly because prolonged exposure to water increases the risk of the key fob getting damaged. If your key fob ceases to functioning after being exposed to rain or clean tap water, remove the battery and clean the electronic component with a towel. Dry it completely before replacing the battery. If the key fob has been exposed to salty or soapy water and salty water, it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If you've tried an entirely new battery for your button and the key fob still isn't locked or unlocking, it's likely that your receiver module has discovered a problem. It's a relatively simple and cheap fix. It is possible to disconnect the 12 volts battery for a few minutes (first remove the negative cable, then press the horn several times) in order to drain any remaining power. Then connect it in reverse. positive cable first, then negative cable later.
ESP Warning Light If the ESP warning light flashes, it is normal and indicates that the car is driving on terrain that has traction issues between the road surface and the tyres isn't optimal, such as gravel, snow or a lot of surface water. If the ESP warning light is continuously blinking, it indicates that there is a problem within the system. This can be detected with a iCarsoft i908 Seat OBD Code Reader which will provide a precise fault description.
Dead Coin Battery
A dead coin battery is one of the most common reasons for the seat alhambra keys to cease to function. The key fob is powered by an insignificant button cell battery that is able to keep it powered. It is recommended to replace it with a replacement that is exactly the same size, voltage and specifications as the original. If you're replacing your battery, be sure to remove all metal clips from the back of the key fob and make sure that the contact points are free of corrosion.
If the key fob was exposed to water (such as rain or soapy tap water) it is recommended to remove and clean the chip using an electronic cleaner or isopropylethanol before installing a new battery. G28 is sensitive to moisture and could be permanently damaged. If the key fob doesn't function after replacing the battery it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery, but it didn't work, or suddenly stopped working the receiver module may have experienced a malfunction. The receiver module is responsible to receive the radio frequency signals that are sent by your remote key fob and transform them into electrical commands that are then used by other modules within the car.
If the receiver module is defective it will not take any commands from your remote key fob. In this situation, you will need to go to a dealer to reprogramme your key fob as well as a new receiver module.
The key fob is encased with rubber to prevent water from getting into the electronic chip. If you submerge the key fob in salted or soapy water it could cause damage to the chip. If your key fob won't work, try cleaning the chip using isopropyl or an electronic cleaner.
If the keys are in a pair but the receiver module has developed a fault you can try restarting all electronics on board by disconnecting the 12 volt battery for a short period of time. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset all the on-board electronics and should bring them back into operation.
Electronic chip that is malfunctioning
The key fob has tiny electronic chips that transmits a message to the receiver module each time the key is used. If the signal does not match the one that the car has stored the immobilizer will turn off and prevent the vehicle from starting. If the key fob does not 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 to make it work again. This can be accomplished by taking the key fob away from its housing and using pins or needles to make contact with each metal retaining clip. If the clips are corroded, or damaged, you'll need to replace them to allow the remote control to function. Make sure that any replacement batteries are of the same size, voltage and specification as the original.
