Seat Alhambra Key Problems
Seat's Jumbo MPV family is among the top in its class when it comes to resale value. With a new generation model available it's even more impressive.
There are a myriad of reasons why the key fob may not function properly, such as a dead coin battery damage to the receiver module, water issues or signal interference. This article will walk you through the steps to make sure it works.
Water Damage
If your key fob for the seat alhambra withstands a wash cycle or a dip in an ocean or a pool, then it is equipped with a waterproof chip. But, you shouldn't do this often, as prolonged exposure to water increases the risk of the key fob getting 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 with paper towel and allow it to dry completely before putting the battery back in. In the event of exposure to salt or soapy water it is recommended to clean the chip with isopropyl alcohol or an electronic cleaner prior to trying to put the battery back in.
Faulty Receiver Module
If you have tried a new button cell battery and the key fob still does not lock or unlock, it is likely that the receiver module has developed a fault. The good news is that this is a simple and affordable fix, you can just disconnect the battery for a few minutes (first take off the negative cable then press the horn button multiple times) to drain any residual electric current, then reconnect it in reverse order e.g. Positive cable first, then negative.
ESP Warning Light - If the ESP warning light is flashing, this is normal and means that the car is driving on terrains that has traction issues between the road surface and the tyres is not ideal like gravel, snow or a lot of surface water. If the ESP warning light is constantly blinking, it indicates that there is an error within the system and should be diagnosed using a iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description.
Dead Coin Battery
A dead battery for the coin is among the most frequent causes for the seat alhambra keys to cease to function. The key fob comes with a small button cell battery that keeps it running. It is recommended to replace it by a new battery that has the same voltage, size, and specification as the original. When replacing the battery on the key fob, remove the metal clips and make sure that the contacts of the key fob are clean and corrosion-free.
If the key fob was exposed to water (such as soapy or rain tap water) it is recommended to remove and clean the chip using an electronic cleaner or isopropyl alcohol before installing a new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob is 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 perform, or stopped working abruptly your receiver module might be experiencing a problem. The receiver module is responsible for receiving 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 damaged and is not able to take any commands from your remote key fob. In this instance you'll be required to visit a service to reprogram your key fob as well as a new receiver module.
The key fob has been sealed with rubber to stop water from leaking into the electronic chip. If you dip the key fob into salted or soapy water it may damage the chips. If your key fob doesn't work, you could try cleaning the chip using isopropyl or electronic cleaner.
If the keys have been linked, but the receiver module is not working then you can restart all the electronics in the board by disconnecting the battery that is 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first before positive). This will reset all on-board electronics and should bring them back to their original functionality.
Electronic Chip Faulty
The key fob is equipped with a small electronic chip that transmits a signal to the receiver module each time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer will be disabled and prevent the vehicle from starting. If the key fob won't work and you aren't able to reprogram it, it could be because of an issue with the microchip.
The chip inside the key fob may have to be changed in order to make it function properly. This can be accomplished by taking the key fob away from its housing, and using pins or needles to connect with each metal retaining clip. You will require replacement in the event of damage or damaged by corrosion. Make sure that the replacement batteries are of the same size, voltage, and specifications as the original one.
