Seat Alhambra Key Problems
Seat's MPV jumbo family is among the best in its class when it comes down to resales values. With a new model on sale, the jumbo family MPV is even better.
There are a number of reasons that the key fob may not function properly, including a dead battery, water damage, receiver module problems or signal interference. This article will guide you through the steps needed to make it work again.
Water Damage
If your key fob for the seat alhambra survives washing cycles, a dip in the ocean or a pool, then it has a waterproof chip. But, you shouldn't do this often because prolonged exposure to water increases the likelihood that the key fob will be damaged. If your key fob stops working after exposure to rain or clean tap water, remove the battery and wipe the electronic component using a paper towel. Let it dry completely before replacing the battery. If the key fob has been exposed to soapy or salty water it is recommended you clean the chip using 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 inexpensive fix. You can remove the 12 volts battery for a few minutes (first remove negative cable, then press the horn several times) to remove any remaining electricity. Then, reconnect it in reverse. Positive first, then negative.
key seat - If the ESP warning light is flashing, this is normal and means that the car is traveling over terrain where the traction of the road surface and the tyres aren't as good, like snow, gravel or a lot of surface water. If the ESP warning light continues to be shining, it is a sign that there is an error within the system. It is best to be diagnosed using a iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop functioning is a dead coin battery. The key fob is powered by a small button-cell battery. Replace it with a brand new battery that is the same voltage, size 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 in good condition and free of corrosion.
If the key fob was exposed to water (such as rain or soapy tap water) it is recommended to remove and clean the chip with an electronic cleaner or isopropyl ethanol prior to installing a new battery. The chip may be permanently damaged by water. If the key fob still isn't working after replacing the battery, it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it did not perform, or stopped working suddenly the receiver module could have experienced a malfunction. The receiver module is responsible for absorbing the radio frequency signals sent by your remote key fob, and changing them into electrical signals which are then processed by other modules in the car.
If the receiver module has developed a fault, it will not respond to any of the commands issued by your remote key fob. In this case, a dealer will need to reprogramme the key fob and install an entirely new receiver.
The key fob is encased with rubber to prevent water from getting inside the electronic chip. If you immerse the key fob into soapy or salty water, it may damage the chips. If your key fob isn't able to work, you can try cleaning the chip using isopropyl or an electronic cleaner.
If the keys are paired, but the receiver module is malfunctioning then you can restart all the electronics in the board by disconnecting the battery at 12 volts for couple of minutes. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset the on-board electronic and restore their functionality.
Electronic chip that is malfunctioning
The key fob is equipped with a chip that transmits the signal from the key to the receiver module each time the key is used. If this signal does not match the one recorded by the car the immobilizer will stop the engine and stop the vehicle from beginning. If the key fob you purchased does not work and you aren't able to reprogram it, it could be due to an incompatible microchip.
The chip in the key fob is not an indefinite part of the device, and might need to be replaced in order to function again. The best way 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 retaining clips made of steel. You will have to replace them in the event that they have been damaged or damaged or corroded. Make sure that any replacement batteries have the same voltage, size and specifications as the original.
