Seat Alhambra Key Problems
Seat's jumbo MPV range is among the top in its class when it comes down to resales values. With a new generation model now on sale it's even more impressive.
There are a variety of reasons that the key fob may not function correctly, including dead battery water damage, receiver module issues 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 the wash cycle or dip in the ocean or in a pool, then it has a waterproof chip. However, don't do it often because prolonged exposure to water can increase the risk that the key fob will be damaged. If the key fob stops working after exposure to clean water from the tap or rain, then just remove the battery, clean the electronic component with a towel and let it dry completely before putting it back in. If you are exposed to soapy water or salt, it is recommended to wash the chip with isopropyl alcohol or electronic cleaner prior to trying to put the battery back in.
Faulty Receiver Module
If the key fob will not lock or unlock even after you've replaced the button cell battery, it is possible that the receiver module has a fault. The good thing is that this is a simple and cost-effective fix. You can just remove the battery 12 volts for several minutes (first remove the negative cable, then press the horn button several times) to drain any residual electricity and then reconnect it in reverse order e.g. positive cable first then negative cable later.
ESP Warning Light If the ESP warning light flashes, this is normal and signifies that the car is travelling through terrain where the traction of the road surface and tyres isn't optimal, like gravel, snow or a lot of surface water.

It should be detected using an iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description.
Dead Coin Battery

Faulty Receiver Module
If your key fob has stopped working after you replaced the battery, but it did not help, or if it stopped working completely in a sudden manner, then your receiver module may have developed an issue. The receiver module receives radio frequency signals from your key fob's remote and converts them into electrical commands which are then acted upon by other modules inside the car.

If the keys have been linked, but the receiver module is malfunctioning it is possible to restart all of the electronics on board by disconnecting the battery that is 12 volts for a couple of minutes. Connect the battery in reverse (negative cable to positive first). This resets all the electronics onboard and will bring them back into operation.
Faulty Electronic Chip
The key fob contains an electronic chip which transmits a signal the receiver module every time the key is used. If the signal does not match the one the car has stored the immobilizer is disabled and prevent the vehicle from starting.

This can be accomplished by taking the key fob out of its housing, and then using a needle or pin to touch each metal clip. You will have to replace them if they are damaged or damaged by corrosion. Make sure any replacement batteries have the same size, voltage, and specification as the original.
