There are a myriad of reasons the key fob may not work properly, including the battery being dead, water damage to the receiver module or signal interference. This article will guide you through the steps necessary to fix it.
Water Damage
If your seat alhambra key fob can withstand washing cycles or a bath in the pool or ocean then it's probably equipped with an amazing waterproof chip. However, do not make it a habit because exposure to water in excess increases the chance of the key fob being damaged. If the key fob stops working after exposure to clean water from the tap or rain, then just remove the battery, clean the electronic component using a paper towel and allow it to dry completely before putting the battery back into. 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 electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after having replaced the button cell battery, it is possible that the receiver module has a fault. The good thing is that this is a simple and cost-effective fix. You can just disconnect the 12 volt battery for about a couple of minutes (first take off the negative cable and then press the horn button several times) to eliminate any remaining electric current, then reconnect it in reverse order e.g. Positive first followed by negative.
ESP Warning Light If the ESP warning light is flashing, this is normal and signifies that the car is driving on terrain where the traction of the road surface and tyres aren't as good, such as gravel, snow or a lot of surface water. If the ESP warning light is constantly blinking, it indicates that there is a glitch in the system. This can be detected using an iCarsoft i908 Seat OBD Code Reader, which will give you a specific fault description.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra key not working is a dead battery. The key fob has a tiny button cell battery that keeps it powered. Replace it with a brand new battery that has the same size, voltage and specifications 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 was exposed to water (such as rain or soapy tap water) it is recommended that you remove and clean the chip with an electronic cleaner or isopropyl ethanol before installing a new battery. The chip can be permanently damaged by water. 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 suddenly the receiver module could have experienced a malfunction. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob and changing them into electrical signals that are then acted on by other modules in the car.
If the receiver module is faulty, it will not accept any commands from your remote key fob. In this case, you will have to visit a dealer for reprogramming your key fob and a new receiver module.
The key fob has been sealed with rubber to stop water from leaking into the electronic chip. If you immerse the key fob into soapy or salty water, it could damage the chip. You can try cleaning the chip by applying isopropyl alcohol or electronic cleaner, however If your key fob does not work after this, you'll have to purchase a new one.
If the keys have been paired, but the receiver module is faulty then you can restart all the electronics on board by disconnecting the 12-volt battery for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.
A malfunctioning electronic chip
The key fob has tiny electronic chips that transmits a message to the receiver module when the key is used. If G28 Car Keys doesn't match the one the car has stored the immobilizer is disabled and stop the vehicle from starting. If the key fob you purchased does not work and you aren't able to reprogram it, it could be due to a faulty microchip.
The chip inside the key fob isn't permanent to the device and might have to be replaced in order to make it work again. The best way to do this is to remove the key from its housing and then 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 corrosion-prone. Make sure that any replacement batteries are of the same size, voltage and specifications as the original.
