There are a number of reasons why the key fob may not function properly including dead coin battery, water damage, receiver module problems or signal interference. This article will walk you through the steps necessary to make sure it works.
Water Damage
If your seat alhambra key fob is able to withstand the wash cycle or a bath in the ocean or pool it's likely to have an amazing waterproof chip. However, be careful not to make this a routine because exposure to water in excess increases the risk of the key fob getting damaged. If the key fob stops functioning after exposure to clean water from the tap or rain, simply take out the battery, wipe the electronic component using a paper towel and allow it to dry completely before putting it back in. If the key fob has been exposed to soapy or salty water it is recommended that you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock even after you've replaced the battery of the button, it is possible that the receiver module has an issue. The good news is that it is a fairly easy repair that is inexpensive, you can remove the battery 12 volts for several minutes (first take off the negative cable, then press the horn button numerous times) to remove any remaining electricity and then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light If the ESP warning light flashes, this is normal and signifies that the car is driving on terrains where the traction between the road surface and tyres isn't optimal, like snow, gravel or a lot of surface water. If the ESP light is constantly flashing, it is a sign there is a problem in the system. This can be identified by using an iCarsoft i908 seat OBD code reader kit. It will provide you with a detailed information about the fault.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop functioning is a dead coin battery. The key fob is powered by a tiny button-cell battery. It is recommended to replace it with a new one that has the same voltage, size and specifications as the original. If you're replacing the battery ensure that you remove all metal clips from the back of the key fob. You should 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 to remove and clean the chip with an electronic cleaner or isopropylethanol before installing a brand new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob still does not work after replacing the battery it could be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery, but it did not function, or suddenly stopped working your receiver module might have experienced a malfunction. The receiver module is responsible for absorbing the radio frequency signals transmitted by the remote key fob and transform them into electrical commands which are then processed 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 scenario, you will need to visit a dealer for reprogramming of your key fob as well as a new receiver module.
The key fob is sealed with rubber to keep water from leaking into the electronic chip. If you immerse your key fob into the ocean's salty or soapy water, the chip inside may be damaged. You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, but If your key fob isn't working after this, then you'll need to purchase a new one.
If The Key Lab are connected, but the receiver module is malfunctioning, you can try to restart all the electronics on board by disconnecting the battery that is 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic circuits and 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 every time the key is used. If the signal does not match the one the car has stored the immobilizer is disabled and prevent 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 an incompatible microchip.
The chip inside the key fob might need to be altered to make it work again. The best way to do this is by removing the key from its housing and then using a pin or needle to connect with each of the clips made of metal. If these clips are damaged or broken, you will have to replace them to allow the remote control to function. Make sure the replacement batteries are of the same size, voltage, and specification as the original.
