Seat Alhambra Key Problems

Seat's Jumbo MPV family is among the top in its class when it comes down to resales value. And with sources tell me , it's better than ever.

There are many reasons why the key fob won't function properly, such as an unresponsive coin battery water damage to the receiver module or signal interference. This article will walk you through the steps to get it back in working order.

Water Damage

If your seat alhambra key fob can withstand the wash cycle or a bath in the pool or ocean it's likely to have an amazing waterproof chip but be careful not to make this a routine because exposure to water in excess increases the risk of the key fob being damaged. If the key fob ceases to functioning after exposure to clean tap water or rain, simply take out the battery, wipe the electronic component with a towel and allow it to dry completely before putting the battery back in. If the key fob has been exposed to salty or soapy water, it is recommended that you clean the chip with isopropyl or electronic cleaner.

Faulty Receiver Module

If the key fob will not lock or unlock after you have replaced the battery of the button, it is possible that the receiver module is suffering from a fault. It is a relatively easy and affordable fix. You can unplug the 12 volt battery for a couple of minutes (first take off the negative cable, then press the horn several times) to drain any remaining electricity. Then reconnect it in reverse. positive cable first, then negative cable later.

ESP Warning Light If the ESP warning light flashes, it is normal and means that the car is traveling through terrain where the traction of the road surface and the tyres is not ideal such as snow, gravel or a lot of surface water. If the ESP warning light continues to be illuminated it indicates that there is an error within the system. It should be detected using an iCarsoft i908 Seat OBD Code Reader kit that will provide you with a specific fault description.

Dead Coin Battery

One of the most frequent reasons for the seat alhambra key not working is a dead coin battery. The key fob is powered by a small button cell battery which keeps it powered. Replace it with a new battery that is the same size, voltage, and specifications as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts of the key fob are in good condition and free of corrosion.

If the key fob was exposed to water, like rain or soapy water, it's recommended that you take the battery off and clean the electronic chip using alcohol or an electronic cleaner before putting in the new battery. The chip can be permanently damaged by water. If the key fob 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 did not work, or stopped working abruptly the receiver module may have encountered a problem. The receiver module takes the 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 receiver module has developed a fault and is unable to respond to any of the commands issued by your remote key fob. In this scenario, you will have to visit a dealer to reprogramme your key fob as well as a new receiver module.

The key fob is encased with rubber to stop water from getting into the electronic chip. If you dip the key fob into soapy or salty water, it may damage the chips. You can try to clean the chip by rubbing it with isopropyl alcohol or electronic cleaner, but If your key fob isn't working after this, then you'll need to buy a new one.

If the keys have been paired but the receiver module has developed a fault, you can try restarting all the on-board electronics by disconnecting the battery at 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset all the electronic components onboard and bring them back into operation.

Faulty Electronic Chip

The key fob houses tiny electronic chips that transmits a message to the receiver module every time the key is used. If this signal does not match the one recorded by the car the immobilizer will stop the engine and prevent the vehicle from starting. If the key fob doesn't work and you are unable to reprogram it, it could be because of a malfunctioning microchip.

The chip inside the key fob might need to be changed in order to make it function properly. The best way to do this is to remove the key from its housing and then using a pin needle to contact each of the retaining clips made of steel. If these are corroded or damaged, you'll need to replace them in order for the remote control to work. Make sure the replacement batteries have the same voltage, size, and specification as the original.
