Seat Alhambra Key Problems
Seat's Jumbo MPV family is among the top in its class when it comes to resale values. And with a new generation model now on sale, it's better than ever.
There are many reasons the key fob could not work properly, including the battery being dead water damage to the receiver module, or signal interference. This article will walk you through the steps necessary to fix it.
Water Damage
If your seat alhambra key fob can withstand an wash cycle or bath in the pool or ocean it's likely to have an amazing waterproof chip but do not make it a habit because prolonged exposure to water increases the risk of the key fob being damaged. If the key fob stops functioning after exposure to clean water from the tap or rain, then just remove the battery, clean the electronic component with a paper towel and allow it to dry completely before putting it back in. In case of exposure to soapy or salty water 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 the key fob does not lock or unlock even after you've replaced the battery in the button cell it is possible that the receiver module has a fault. It's a simple and affordable fix. You can unplug the 12 volt battery for a few minutes (first remove the negative cable, then press the horn several times) to eliminate any remaining power. Then, reconnect it in reverse. Positive cable first and then negative.
ESP Warning Light – If the ESP symbol blinks, it is normal. It indicates that you are driving over terrain with poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly on, it indicates that there is a fault in the system. This can be identified with a iCarsoft i908 seat OBD code reader kit. It will give you the full description of the problem.
Dead Coin Battery
A dead battery for the coin is one of the most common causes for the keys for the seat to stop working. The key fob is powered by a small button-cell battery. It should be replaced with a new one with the same voltage, size and specifications as the original. When replacing the battery on the key fob, remove the metal clips and make sure that the contacts on the key fob are in good condition and free of corrosion.
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 isopropylethanol before installing a new battery. The chip is susceptible to moisture and could be permanently damaged. If seat keys 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 functioning after replacing the battery, but it did not work, or if it stopped working suddenly the receiver module could have experienced a malfunction. The receiver module is responsible for absorbing the radio frequency signals that are sent by the remote key fob and convert them into electrical signals that are then utilized by other modules in the car.
If the receiver module has suffered a malfunction it will not respond to any of the commands received by your remote key fob. In this case it is necessary for a dealer to reprogramme your key fob, and also install an entirely new receiver.
The key fob comes with rubber seals to prevent water from entering the chip inside. However, if you submerge your key fob in salted or soapy ocean water, the chip inside may be damaged. You can attempt to clean the chip by using isopropyl Alcohol to rub it or electronic cleaner, but in the event that your key fob does not work after this, then you'll need to purchase a new one.
If the keys are connected, but the receiver module isn't working it is possible to restart all the electronics that are on board by disconnecting the battery with 12 volts for a couple of minutes. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset the onboard electronic and restore their functionality.
Electronic chip that is malfunctioning
The key fob houses a small electronic chip which transmits a signal the receiver module each time the key is used. If the signal doesn't match that stored by the car the immobilizer will stop the engine and stop the vehicle from beginning. If the key fob does not work and you aren't able to reprogram it, it could be because of an incompatible microchip.
The chip inside the key fob isn't a permanent part of the device and might have to be replaced in order to function again. The best method to do this is by removing the key from its housing and 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 of damage or damaged by corrosion. Make sure the replacement batteries have the same voltage, size, and specification as the original.
