Seat Alhambra Key Problems
Seat's jumbo family MPV is among the top in its class in terms of keeping resales value. With a new generation model now available, it's even better.
There are many reasons that the key fob might not function correctly, including dead battery or water damage, receiver module issues or signal interference. This article will walk you through the steps to make sure it works.
Water Damage
If your key fob for the seat alhambra withstands the wash cycle or a dip in an ocean or a pool then it's equipped with a waterproof chip. But don't do this often as excessive exposure to water increases the likelihood that the key fob will be damaged. If the key fob stops functioning after exposure to clean water from the tap or rain, simply take out the battery, clean the electronic component with paper towel and allow it to dry completely before putting it back into. If the key fob has been exposed to soapy or salty water it is recommended you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock even after you've replaced the button cell battery, it is possible that the receiver module is suffering from an issue. www.thekeylab.co.uk is that this is a relatively simple and affordable fix, you can simply disconnect the 12 volt battery for about a couple of minutes (first remove the negative cable and press the horn button several times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light If the ESP warning light flashes, it is normal and signifies that the car is driving on terrain that has traction issues between the road surface and tyres aren't as good, such as gravel, snow or a lot of surface water. If the ESP warning light remains blinking, it indicates that there is a fault within the system. It should be detected with 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 to stop functioning is a dead coin battery. The key fob is powered by a small button-cell battery. Replace it with a new battery that has the exact voltage, size and specification 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 make sure the contacts are clean and free of corrosion.
If the key fob has been exposed water, like soapy or rain it is recommended to take the battery off and clean the electronic chip with isopropyl alcohol or a electronic cleaner before putting in the new battery. The chip can be permanently damaged by water. 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 replacing the battery, but it didn't function, or stopped working in a sudden manner the receiver module could have experienced a malfunction. The receiver module receives radio frequency signals from your remote keyfob and transforms them into electrical signals which are then acted upon by other modules within the car.
If the receiver module has a problem it will not take any commands from your remote key fob. In this instance, you will need to visit a dealer to reprogram your key fob as well as a new receiver module.
The key fob has been sealed with rubber to stop water from entering the electronic chip. If you immerse the key fob in salty or soapy water, it may damage the chips. You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, but in the event that your key fob isn't working after all this, you'll have to purchase a new one.
If the keys are in a pair but the receiver module has developed a fault, you can try restarting all of the electronics on board by disconnecting the battery that is 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic circuits and restore their functionality.
A malfunctioning electronic chip
The key fob houses tiny electronic chips that transmits a message to the receiver module when the key is used. If the signal isn't in line with the one the car has stored the immobilizer will turn off and prevent the vehicle starting. If the key fob won't work and you are unable to reprogram it, this could be because of an incompatible microchip.
The chip inside the key fob could need to be replaced to allow it to function again. This can be done by getting the key fob removed from its housing and using pins or needles to touch each metal clip. If the clips are corroded, or damaged, you'll require replacement in order for the remote control to function. Make sure that the replacement batteries are of the same size, voltage and specifications as the original one.
