There are many reasons the key fob could not perform as it should, including an unresponsive coin battery damage to the receiver module, or signal interference. This article will guide you through the steps necessary to make sure it works.

Water Damage

If your key fob for the seat Alhambra is able to withstand an wash cycle, a dip in the ocean or a pool, then it has a waterproof chip. But be careful not to do this often since prolonged exposure to water can increase the chance of the key fob getting damaged. If your key fob stops functioning after being exposed to rain or clean tap water, take out the battery and clean the electronic component with a paper towel. Let it dry completely before replacing the battery. If you are exposed to soapy water or salt, it is recommended that you clean the chip with isopropyl alcohol or an electronic cleaner prior to trying to put the battery back in.

Faulty Receiver Module

If you've tried a new button cell battery and the key fob doesn't lock or unlock then it's likely that your receiver module has found a fault. It's a fairly simple and inexpensive fix. You can remove the battery with 12 volts for a few minutes (first remove negative cable, then press the horn a few times) to drain any remaining electricity. Then, reconnect it in reverse. Positive first, then negative.

ESP Warning Light - If the ESP warning light flashes, this is normal and indicates that the car is driving on terrains where the traction between the road surface and tyres isn't optimal, like snow, gravel or lots of surface water. If the ESP warning light remains shining, it is a sign that there is an error within the system. It is best to be detected using an iCarsoft i908 Seat OBD Code Reader kit which will give you a specific fault description.


seat replacement key cost 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. Replace it with a brand new battery with the same dimensions, voltage and specs as the original. If you're replacing the battery be sure to remove all metal clips from the back of the key fob and make sure that the contact points are clean and free of corrosion.

If the key fob was exposed to water (such as soapy tap water) it is recommended that you remove and clean the chip using an electronic cleaner or isopropylethanol before installing a brand new battery. The chip can be permanently damaged by water. If the key fob still doesn't function after replacing the battery, it might be necessary to replace the 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 abruptly the receiver module may have experienced a malfunction. The receiver module is responsible for receiving the radio frequency signals that are sent by your remote key fob, and transform them into electrical commands that are then used by other modules within the car.

If the receiver module has a problem, it will not accept any commands from your remote key fob. In this case it is necessary for a dealer to reprogramme the key fob, and also install an entirely new receiver.

The key fob is sealed with rubber to prevent water from leaking into the electronic chip. However, if you submerge the key fob in the ocean's salty or soapy water, the chip inside could be damaged. You can try to clean the chip by using isopropyl Alcohol to rub it or electronic cleaner, however in the event that your key fob does not work after this, then you'll need to purchase a replacement.

If the keys are in a pair but the receiver module has developed a fault you can try to reboot all electronics on board by disconnecting the 12 volt battery for a few minutes. Then, reconnect the battery in reverse order (negative cable first, then positive). This will reset all electronics onboard and will restore their functionality.

Electronic Chip Faulty

The key fob is equipped with a tiny chip that transmits the signal from the key to the receiver module each time the key is used. If the signal received does not match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. If the key fob won't work and you are unable to reprogram it, this could be due to a faulty microchip.

The chip inside the key fob may have to be altered to make it work again. This can be accomplished by removing the key fob from its housing, and then using a needle or pin to make contact with each metal retaining clip. If these are corroded or damaged, you'll have to replace them to allow the remote control to function. Make sure that any replacement batteries are the same size, voltage and specification as the original.
