Seat Alhambra Key Problems Seat's jumbo family MPV is among the best in the market in terms of maintaining resale value. And with a brand new model available it's even better. There are a myriad of reasons the key fob could not work as expected, including the battery being dead damage to the receiver module, 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 washing cycles or a bath in the ocean or pool it's likely to have an amazing waterproof chip. However, G28 make this a habit because exposure to water in excess increases the chance of the key fob getting damaged. If the key fob ceases to functioning after exposure to clean water from the tap or rain then simply remove the battery, clean the electronic component with a paper towel and let it dry completely before putting the battery back in. If the key fob has been exposed to salty or soapy water and salty water, it is recommended you clean the chip with isopropyl or an electronic cleaner. Faulty Receiver Module If you have tried a new button cell battery and the key fob still cannot be locked or unlocked, it's likely that your receiver module has developed a fault. It is a relatively easy and affordable fix. You can unplug the 12 volts battery for a couple of minutes (first remove the negative cable and then press the horn several times) to drain any remaining electricity. Then, reconnect it in reverse. Positive first, then negative. ESP Warning Light – If the ESP symbol flashes, this is normal. It means that you are driving on a terrain with poor traction. This could be due to snow, gravel or surface water. If the ESP warning light is constantly illuminated it indicates that there is an error within the system. This can be diagnosed using a iCarsoft i908 Seat OBD Code Reader kit that will give you a specific 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 tiny button-cell battery. It should be replaced with a replacement that has identical in size, voltage and specifications as the original. If you are replacing the battery, be sure to remove all metal clips from the back of the key fob. You should also ensure that the contacts are clean and free of corrosion. If the key fob was exposed to water (such as soapy tap water) it is recommended that you remove and clean the chip using an electronic cleaner or isopropyl alcohol prior to installing a new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob still not working after replacing the battery, it could be necessary to replace the entire key fob. Faulty Receiver Module If your key fob has stopped working after replacing the battery and it did not help, or it suddenly stopped working without notice it is possible that your receiver module may have developed an issue. The receiver module is able to receive radio frequency signals from your remote keyfob, and transforms them into electrical signals that are then followed by other modules within the car. If the receiver module has developed a fault it will not respond to any of the commands sent by your remote key fob. In this instance, you will be required to visit a service to reprogram your key fob and new receiver module. The key fob is fitted with rubber seals to prevent water from entering the electronic chip inside. If you submerge the key fob in soapy or salty water, it could damage the chip. You can try cleaning the chip by using isopropyl Alcohol to rub it or electronic cleaner, but in the event that your key fob doesn't work after doing this, then you'll need to purchase a replacement. If the keys have been paired, but the receiver module is not working it is possible to restart all the electronics that are on board by disconnecting the battery at 12 volts for few minutes. Connect the battery in reverse (negative cable to positive first). This will reset all the electronics onboard and will restore their functionality. Electronic chip that is malfunctioning The key fob houses tiny electronic chips that transmits a signal to the receiver module each time the key is used. If the signal isn't in line with the one the car has stored, the immobilizer will disable and prevent the vehicle from starting. If the key fob doesn't work and you aren't able to reprogram it, this could be due to a malfunctioning microchip. The chip inside the key fob isn't an irreplaceable part of the device and may need to be replaced in order to function again. The best way to do this is by removing the key from its housing and using a pin or needle to connect with each of the metal clips that hold it. You'll have to replace them in the event of damage or damaged or corroded. Make sure that any replacement batteries have the same voltage, size and specifications as the original.
