Seat Alhambra Key Problems
Seat's jumbo family MPV is among the top in its class in terms of conserving resale value. With a new model available for sale the jumbo family MPV is even better.
There are a variety of reasons that the key fob might not work properly including dead coin battery or water damage, receiver module issues or signal interference. This article will guide you through the steps to make sure it works.
Water Damage
If your seat alhambra keyfob is able to survive an wash cycle or bath in the pool or ocean then it probably has an amazing waterproof chip. However, do not make it a habit as exposure to excessive water increases the risk of the key fob getting damaged. If the key fob ceases to functioning after exposure to clean tap water or rain, then just remove the battery, clean the electronic component with a towel and allow it to dry completely before putting the battery back in. In case of exposure to soapy water or salt, it is recommended that you clean the chip with isopropyl alcohol or electronic cleaner prior to trying to put the battery back in.
Faulty Receiver Module
If you have tried an entirely new battery for your button and the key fob still cannot be locked or unlocked, it's likely the receiver module has developed a fault. The good news is that it is a relatively simple and inexpensive repair, you can just remove the battery 12 volts for about a couple of minutes (first remove the negative cable and press the horn button a few times) to eliminate any remaining 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 seat key is driving on terrain that has traction issues between the road surface and the tyres is not ideal such as gravel, snow or a lot of surface water. If the ESP warning light is constantly shining, it is a sign that there is a glitch in the system and should be detected with a iCarsoft i908 Seat OBD Code Reader which will provide a precise fault description.
Dead Coin Battery
A dead battery for the coin is one of the most frequent reasons for the seat alhambra keys to stop working. The key fob is powered by a tiny button-cell battery. Replace it with a new battery that has the exact voltage, size and specification as the original. If you are replacing the battery, ensure that you 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 remove the battery and clean the electronic chip using isopropyl alcohol or a electronic cleaner prior to installing the new battery. The chip could be permanently damaged by moisture. If the key fob is still not working after replacing the battery, it may be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob was not working after replacing the battery, but it didn't perform, or suddenly stopped working the receiver module may be experiencing a problem. The receiver module is responsible to receive the radio frequency signals transmitted by the remote key fob and converting them into electrical commands that are then used by other modules in your
car seat key.
If the receiver module has a problem and is not able to take any commands from your remote key fob. In this instance, a dealer will need to reprogram your key fob, and also install the new receiver.
The key fob is sealed by rubber to block water from getting into the electronic chip. If you dip the key fob into salted or soapy water it could cause damage to the chip. It is possible to clean the chip by rub it with isopropyl alcohol or electronic cleaner, but If your key fob does not work after this, then you'll need to purchase a replacement.
If the keys are connected but the receiver module has developed a fault you may try to restart all of 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 resets all the electronic components onboard and bring them back to their original functionality.
A malfunctioning electronic chip
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 isn't in line with the one the car has stored the immobilizer will be 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 a faulty microchip.
The chip in the key fob is not permanent to the device and may need to be replaced to get it to work again. The best method to do this is by removing the key from its housing and then using a pin or needle to get into contact with each of the retaining clips made of steel. If these clips are damaged or broken, you will have to replace them to allow the remote control to work. Make sure any replacement batteries are of the same voltage, size, and specification as the original.
