There are many reasons why the key fob won't work properly, including an unresponsive coin battery water damage to the receiver module or signal interference. This article will guide you through the steps needed to make it work again.

Water Damage

If your seat alhambra keyfob is able to survive an wash cycle or bath in the pool or ocean then it is likely to have an incredible waterproof chip, but don't make this a habit because exposure to water in excess increases the chance of the key fob being damaged. If the key fob ceases to working after exposure to clean tap water or rain, just take out the battery, wipe the electronic component with paper towel and let it dry completely before putting it back into. If the key fob has been exposed to salty or soapy water it is recommended you clean the chip using isopropyl or an electronic cleaner.

Faulty Receiver Module

If the key fob will not lock or unlock after you have replaced the button cell battery it could be that the receiver module has a fault. The good thing is that this is an easy and inexpensive repair, you can simply remove the battery 12 volts for about a couple of minutes (first remove the negative cable then press the horn button multiple times) to eliminate any remaining electrical current and then reconnect it in reverse order e.g. Positive cable first and then negative.

ESP Warning Light - If the ESP warning symbol flashes this is normal and indicates that the car is driving over terrain that has traction issues between the road surface and tyres isn't ideal, such as snow, gravel or lots of surface water. If the ESP light is always on, it is a sign that there is a flaw in the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit.

Dead Coin Battery

One of the most frequent reasons for the seat alhambra key not functioning is a dead coin battery. The key fob comes with a small button cell battery that keeps it running. It is recommended to replace it with a new one that has 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 clean 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 using an electronic cleaner or isopropyl ethanol before installing a brand new battery. The chip could be permanently damaged by water. If the key fob still doesn't work after replacing the battery it could be necessary to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after replacing the battery and it didn't help, or if it suddenly stopped working without notice it is possible that your receiver module may have developed a fault. The receiver module is able to receive 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 is faulty it will not take any commands from your remote key fob. In this scenario the dealer will have to reprogramme your key fob as well as install a new receiver.

The key fob is covered with rubber to stop water from getting inside the electronic chip. If The KeyLab dip the key fob into salty or soapy water it could cause damage to the chip. If your key fob doesn't work, you can try cleaning the chip using isopropyl or an electronic cleaner.

If the keys are connected but the receiver module has developed a fault you can try restarting all electronics on board by disconnecting the battery that is 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic circuit and restore their functionality.

Faulty Electronic Chip

The key fob houses tiny electronic chips that sends a signal to the receiver module every time the key is used. If this signal does not match the one stored by the car the immobilizer will stop the engine and prevent the vehicle from starting. If, however, the key fob isn't working and you are not able to reprogram it this could be due to a defective chip.

The chip in the key fob isn't permanent to the device and may need to be replaced to get it to work again. The most effective method for doing this is by removing the key from its housing and using a pin or needle to connect with each of the retaining clips made of steel. If they are corroded or broken, you will require replacement in order for the remote control to function. Make sure that any replacement batteries are of the same voltage, size and specifications as the original.

The Seat Alhambra is a well-designed and popular model but like any other car it can occasionally experience issues with particular parts or equipment.

The infotainment systems can also fail and freeze the screens.
