Seat Alhambra Key Problems
Seat's jumbo family MPV is one of the best in the class when it comes to conserving resale value. And with a new model now available it's even better.
There are a variety of reasons why the key fob may not perform as it should, including a dead coin battery damage to the receiver module, or signal interference. This article will walk you through the steps needed to get it back to working.
Water Damage
If your seat alhambra key fob is able to withstand an wash cycle or bath in the ocean or pool then it is likely to have an amazing waterproof chip but be careful not to make this a routine because prolonged exposure to water increases the risk of the key fob being damaged. If the key fob stops functioning after exposure to clean tap water or rain then simply remove the battery, clean the electronic component with paper towel and let it dry completely before putting it back in. In case of exposure to soapy water or salt, it is recommended to clean the chip with isopropyl alcohol or electronic cleaner prior to attempting to put the battery back in.
Faulty Receiver Module
If you've tried an entirely new battery for your button and the key fob still doesn't lock or unlock then it's likely the receiver module has found a fault. It's a fairly simple and cost-effective fix. You can unplug the 12 volts battery for a couple of minutes (first remove the negative cable and then press the horn a few times) in order to drain any remaining power. Then connect it in reverse. positive cable first and then negative.
ESP Warning Light - If the ESP warning light is flashing, this is normal and means that the car is driving over terrain that has traction issues between the road surface and the tyres isn't optimal, like snow, gravel or a lot of surface water. If the ESP warning light remains illuminated it indicates that there is an error within the system. This can be diagnosed using a iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not working is a dead battery. The key fob is powered by a small button-cell battery. It is recommended to replace it with a new one with the same size, voltage and specifications 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 that you remove and clean the chip with an electronic cleaner or isopropyl alcohol before installing a new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob still isn't working after replacing the battery it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery, but it did not work, or if it stopped working suddenly your receiver module might have encountered a problem. The receiver module is responsible for receiving the radio frequency signals transmitted by your remote key fob, and convert them into electrical signals that are then acted on by other modules in your car.
If seat replacement key has suffered a malfunction and is unable to respond to any of the commands transmitted by your remote key fob. In this scenario, you will need to visit a dealer to reprogramme your key fob and a new receiver module.
The key fob is sealed with rubber to prevent water from entering the electronic chip. If you immerse your key fob in soapy water or salty ocean water, the chips inside may be damaged. If your key fob doesn't function, you can try cleaning the chip with isopropyl or an electronic cleaner.
If the keys are linked, but the receiver module isn't working, you can try to restart all the electronics on board by disconnecting the battery that is 12 volts for a few minutes. Then reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic circuits and restore their functionality.
Faulty Electronic Chip
The key fob contains a small electronic chip that transmits a signal to the receiver module whenever the key is used. If the signal doesn't match the one the car has stored, the immobilizer will disable and prevent the vehicle from starting. If the key fob you purchased does not function and you are not able to reprogram it, it could be because of an incompatible microchip.
The chip inside the key fob is not an irreplaceable part of the device and could need to be replaced in order to make it work again. This can be accomplished by taking the key fob away from its housing, and then using a needle or pin to contact each metal retaining clip. You'll require replacement in the event of damage or damaged or corroded. Make sure that any replacement batteries are the same size, voltage, and specifications as the original.
