Seat Alhambra Key Problems Seat's jumbo family MPV is one of the best in class in terms of retaining resale value. And with a new model now available, it's better than ever. There are a myriad of reasons that the key fob might not work properly including dead coin battery, damage to the receiver module, water issues, or signal interference. This article will walk you through the steps to get it back to working. Water Damage If your key fob for the seat Alhambra is able to withstand a wash cycle, a dip in the ocean or in a pool, then it's got a waterproof chip. However, don't do it often as excessive exposure to water can increase the risk of the key fob becoming damaged. If your key fob stops functioning after exposure to rain or clean tap water, unplug the battery and clean the electronic component using a paper towel. Dry it completely before replacing the battery. If the key fob has been exposed to soapy or salty water, it is recommended that you clean the chip with isopropyl or an electronic cleaner. Faulty Receiver Module If the key fob will not lock or unlock after you've replaced the button cell battery It is possible that the receiver module is suffering from a fault. The good news is that it is a relatively simple and affordable fix, you can just disconnect the battery for just a few minutes (first take off the negative cable then press the horn button numerous times) to remove any remaining electricity, and then connect it in reverse order e.g. Positive first, then negative. ESP Warning Light – If the ESP warning light flashes, this is normal and means that the car is driving through terrain where the traction between the road surface and the tyres aren't as good, like gravel, snow or a lot of surface water. If the ESP warning light is constantly flashing, it means there is a fault within the system. This can be detected using an iCarsoft i908 Seat OBD Code Reader kit which will provide a precise fault description. Dead Coin Battery A dead battery for the coin is one of the most common causes for the seat alhambra keys to cease to function. The key fob is powered by a small button-cell battery. It is recommended to replace it with a new one that is the same size, voltage, and specification as the original. If you're replacing your battery, ensure that you remove all metal retaining clips from the back of the key fob. You should also make sure the contacts are clean and free of corrosion. If the key fob was exposed to water (such as soapy tap water), it is recommended to remove and clean the chip with an electronic cleaner or isopropyl alcohol before installing a brand new battery. The chip can be permanently damaged by water. 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 stopped working after replacing the battery, but it did not function, or stopped working suddenly, your receiver module could have experienced a malfunction. The receiver module is responsible for absorbing the radio frequency signals that are sent by your remote key fob, and converting them into electrical commands that are then acted on by other modules in the car. If the receiver module has a problem and is not able to take any commands from your remote key fob. In this instance you'll have to visit a dealer for reprogramming of your key fob as well as a new receiver module. The key fob is sealed with rubber to stop water from getting inside the electronic chip. If you submerge the key fob in salted or soapy water it may damage the chips. If your key fob isn't able to work, you could try cleaning the chip with isopropyl or electronic cleaner. If the keys have been successfully paired, but your receiver module isn't working, you can try to restart all the electronics in the board by disconnecting the battery with 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first, then positive). seat ibiza keys will reset the on-board electronic and restore their functionality. Electronic Chip Faulty The key fob houses tiny electronic chips which transmits a signal the receiver module each time the key is used. If the signal received does not match that stored by the car the immobilizer will shut down the engine and prevent the vehicle from beginning. If the key fob isn't functioning and you are unable to reprogram it the issue could be due to a malfunctioning chip. The chip in the key fob isn't an indefinite part of the device and could need to be replaced to make it work again. The best method to do this is to remove the key from its housing and then using a pin needle to get into contact with each of the metal clips that hold it. You'll have to replace them in the event that they have been damaged or corroded. Make sure that the replacement batteries have the same size, voltage, and specification as the original.
