There are many reasons the key fob won't perform as it should, including an inoperative coin battery or 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 key fob can withstand washing cycles or a bath in the ocean or pool then it is likely to have an amazing waterproof chip but do not make it a habit because exposure to water in excess increases the risk of the key fob getting damaged. If your key fob stops functioning after being exposed to rain or clean tap water, you should remove the battery and wipe the electronic component with a towel. Dry it completely before replacing the battery. If you are exposed to soapy water or salt, it is recommended to clean the chip using isopropyl alcohol or a electronic cleaner before attempting to put the battery back in.

Faulty Receiver Module

If you have tried a new battery for a button and the key fob doesn't lock or unlock then it's likely that your receiver module has found a fault. The good thing is that this is a simple and cost-effective fix. You can remove the battery 12 volts for about a couple of minutes (first take off the negative cable, then press the horn button a few times) to eliminate any remaining electric current, then reconnect it in reverse order e.g. Positive cable first followed by negative.

ESP Warning Light If the ESP warning symbol flashes this is normal and indicates that the vehicle is driving through terrain where the traction of the road surface and tyres aren't as good, such as gravel, snow or a lot of surface water. If the ESP light is always on, it is a sign that there is a problem with the system. It can be detected by using an iCarsoft i908 seat OBD code reader kit. It will provide the full description of the problem.

Dead Coin Battery


One of the most common reasons for the seat alhambra key to stop working is a dead battery. The key fob is powered by a small button-cell battery. Replace it with a brand new battery that is the same size, voltage and specifications as the original. If you're replacing the battery ensure that you remove all metal retaining clips from the back of the key fob. Also make sure that the contact points are 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 with an electronic cleaner or isopropyl alcohol before installing a brand new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob still isn't working after replacing the battery it could be necessary to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after you replaced the battery and it didn't help, or if it suddenly stopped working out of the blue the receiver module might have developed an issue. The receiver module is responsible for absorbing the radio frequency signals transmitted by your remote key fob, and convert them into electrical signals which are then processed by other modules within the car.

If www.thekeylab.co.uk has developed a fault that prevents it from responding to any of the commands received by your remote key fob. In this scenario, you will be required to visit a service for reprogramming of your key fob as well as a new receiver module.

The key fob is sealed with rubber to keep water from leaking into the electronic chip. If you immerse the key fob in salty or soapy water it could cause damage to the chip. It is possible to clean the chip by rub it with isopropyl alcohol or electronic cleaner, but in the event that your key fob isn't working after all this, then you'll need to purchase a new one.

If the keys have been paired but the receiver module has developed a fault, you can try restarting all of the onboard electronics by removing the 12 volt battery for a few minutes. Then, reconnect the battery in reverse order (negative cable first, then positive). This will reset all the electronic components onboard and restore their functionality.

Faulty Electronic Chip

The key fob is equipped with a tiny chip which transmits a signal from the key to the receiver module each time the key is used. If the signal does not match the one the car has stored, the immobilizer will disable and stop the vehicle from starting. If the key fob you purchased does not work and you aren't able to reprogram it, this could be because of an issue with the microchip.

The chip in the key fob is not an irreplaceable part of the device and could need to be replaced to get it to work again. The best method to do this is by removing the key from its housing and using a pin needle to connect with each of the retaining clips made of steel. If the clips are corroded, or damaged, you'll need to replace them to allow the remote control to function. Make sure that the replacement batteries are the same size, voltage, and specification as the original one.
