There are a variety of reasons that the key fob may not function properly, such as a dead coin battery, damage to the receiver module, water issues, or signal interference. This article will walk you through the steps necessary to get it working.
Water Damage
If your key fob for the seat alhambra survives an wash cycle or a dip in the ocean or a pool, then it is equipped with a waterproof chip. However, don't do it often, as prolonged exposure to water increases the risk of the key fob becoming damaged. If the key fob stops functioning after exposure to clean tap water or rain then simply remove the battery, clean the electronic component with a paper towel and allow it to dry completely before putting the battery back into. If the key fob has been exposed to soapy or salty water, it is recommended that you clean the chip with isopropyl or electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after you have replaced the button cell battery, it is possible that the receiver module is suffering from a fault. The positive side is that this is an easy and cost-effective fix. You can just disconnect the 12 volt battery for several minutes (first remove the negative cable then press the horn button multiple 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 means that the vehicle is driving over terrain in which the traction between the road surface and the tyres is not ideal like snow, gravel or a lot of surface water. If the ESP warning light is continuously flashing, it means there is an error within the system and should be diagnosed using a iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description.
Dead Coin Battery
A dead battery for the coin is among the most common reasons for the keys for the seat to stop working. The key fob is powered by a small button cell battery that is able to keep it powered. It is recommended to replace it with a new one that has the same size, voltage and specifications as the original. If you're replacing your battery, ensure that you remove all metal clips from the back of the key fob. You should also ensure that the contacts are free of corrosion.
If the key fob was exposed to water, such as soapy or rain, it's recommended that you remove the battery and clean the electronic chip with isopropyl alcohol or a electronic cleaner prior to inserting the new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob does not work after replacing the battery it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob was not working after replacing the battery, but it did not function, or stopped working abruptly the receiver module may be experiencing a problem. The receiver module is responsible to receive the radio frequency signals sent by the remote key fob and transform them into electrical commands that are then utilized by other modules in the car.
If the receiver module has suffered a malfunction that prevents it from responding to any of the commands sent by your remote key fob. In this case you will require a dealer to reprogramme the key fob, and also install an additional receiver.
The key fob comes with rubber seals that prevent water from getting into the electronic chip inside. If you dip the key fob in soapy or salty water, it could damage the chip. It is possible to clean the chip by applying isopropyl alcohol or electronic cleaner, however if your key fob still doesn't work after doing this, then you'll need to buy a new one.
If the keys are 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 the on-board electronic and restore their functionality.
A malfunctioning electronic chip
The key fob is equipped with a small electronic chip that sends a signal to the receiver module whenever the key is used. If the signal does not match the one the car has stored, the immobilizer will disable and stop the car from starting. If, however, the key fob isn't working, and you are unable to reprogram it the issue could be due to a faulty chip.
The chip inside the key fob isn't a permanent part of the device and might have to be replaced to get it to work again. This can be done by getting the key fob removed from its housing and using pins or needles to contact each metal retaining clip. You'll need to replace these if they are damaged or corrosion-prone. Make sure that any replacement batteries have the same voltage, size and specifications as the original.
