Seat Alhambra Key Problems
Seat's MPV jumbo family is among the top in its class when it comes to resale value. With a new model available for sale, the jumbo family MPV is even more impressive.
There are many reasons the key fob won't perform as it should, including the battery being dead, water damage to the receiver module, or signal interference. This article will walk you through the steps necessary to fix it.
Water Damage
If your seat alhambra key fob survives an wash cycle or bath in the ocean or pool then it's probably equipped with an incredible waterproof chip, but do not use it regularly since exposure to excessive water increases the chance of the key fob becoming damaged. If the key fob ceases to functioning after exposure to clean tap water or rain, then just remove the battery, wipe the electronic component with a paper towel and allow it to dry completely before putting the battery back into. If the key fob has been exposed to soapy or salty 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 does not lock or unlock, it's likely that your receiver module has been faulty. The good news is that this is a relatively simple and cost-effective fix. You can just disconnect the battery for several minutes (first remove the negative cable and press the horn button a few times) to drain any residual electrical current and then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light If the ESP warning symbol flashes this is normal and means that the car is travelling on terrain where the traction between the road surface and tyres is not ideal such as 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. This can be detected using an iCarsoft i908 Seat OBD Code Reader which will provide you with a specific fault description.
Dead Coin Battery
A dead coin battery is one of the most frequent causes for the seat alhambra keys to stop working. The key fob is powered by a tiny button-cell battery. It should be replaced with a new one that has exactly the same size, voltage, and specification as the original. When replacing the battery on the key fob, remove all metal clips and ensure that the contacts of the key fob are clean and free of corrosion.
If the key fob has been exposed to water, such as rain or soapy water, it's recommended that you take the battery off and clean the electronic chip using isopropyl alcohol or an 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 has stopped working after you replaced the battery but it didn't help, or it suddenly stopped working out of the blue it is possible that your receiver module could have developed a fault. The receiver module receives radio frequency signals from your remote keyfob and transforms them into electrical signals which are then used by other modules in the car.
If the receiver module is damaged it will not take any commands from your remote key fob. In this situation, a dealer will need to reprogramme your key fob, and also install the new receiver.
The key fob is covered with rubber to keep water from getting inside the electronic chip. If you immerse your key fob into soapy water or salty ocean water, the chip inside may be damaged. If seat car key battery replacement does not work, try cleaning the chip using isopropyl or an electronic cleaner.
If the keys have been paired but the receiver module has developed a fault, you can try rebooting all the on-board electronics by disconnecting the battery at 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset all electronic components onboard and bring them back into operation.
A malfunctioning electronic chip
The key fob is equipped with an electronic chip that sends a signal to the receiver module whenever the key is used. If this signal does not match the one stored by the car the immobilizer will stop the engine and stop the vehicle from starting. If the key fob does not work and you aren't able to reprogram it, this could be because of a faulty microchip.
The chip in the key fob might need to be replaced in order to get it working again. The most effective method for doing this is by removing the key from its housing and then using a pin needle to contact each of the clips made of metal. If they are corroded or damaged, you'll need to replace them in order for the remote control to function. Make sure that the replacement batteries are the same size, voltage and specifications as the original one.
