There are a variety of reasons why the key fob may not function correctly, including dead battery or water damage, receiver module issues, or signal interference. This article will walk you through the steps to make it work again.
Water Damage
If your key fob for the seat alhambra survives the wash cycle or a dip in an 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 risk of the key fob getting damaged.

If the key fob was exposed to salty or soapy water and salty water, it is recommended you clean the chip using isopropyl or electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after having replaced the battery of the button it could be that the receiver module is suffering from an issue. It's a relatively simple and cost-effective fix. You can remove the battery that is 12 volts for a few minutes (first remove the negative cable, then press the horn a few times) to remove any remaining power. Then connect it in reverse. positive cable first and then negative cable later.
ESP Warning Light If the ESP warning light is flashing, this is normal and indicates that the car is travelling on terrains where the traction between the road surface and the tyres is not ideal like snow, gravel or lots of surface water. If the ESP warning light remains blinking, it indicates that there is an error within the system. It is best to be detected with a iCarsoft i908 Seat OBD Code Reader, which will give you a specific fault description.
Dead Coin Battery
A dead battery for the coin is one of the most common reasons for the keys for the seat to stop working. The key fob contains a small button cell battery that is able to keep it powered. It should be replaced with a new one with the same voltage, size and specifications 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 the contacts are clean and free of corrosion.
If the key fob was exposed to water, like rain or soapy water it is recommended to take the battery off and clean the electronic chip using alcohol isopropyl or an electronic cleaner prior to inserting the new battery. The chip can be permanently damaged by moisture. If the key fob still not working after replacing the battery, it might be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob stopped working after you replaced the battery, but it didn't help, or if it just stopped working suddenly the receiver module could have developed an issue. The KeyLab takes the radio frequency signals from your remote keyfob, and transforms them into electrical signals that are then processed by other modules inside the car.
If the receiver module is damaged, it will not accept any commands from your remote key fob. In this instance, a dealer will need to reprogramme the key fob and install an entirely new receiver.
The key fob features rubber seals to prevent water from getting into the electronic chip inside. If you immerse the key fob into salty or soapy water, it could cause damage to the chip. You can attempt to clean the chip by applying isopropyl alcohol or electronic cleaner, however in the event that your key fob isn't working after all this, you'll have to purchase a replacement.
If the keys have been paired but the receiver module has developed a fault you can try to reboot all electronics on board by disconnecting the battery that is 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality.
Faulty Electronic Chip
The key fob comes with a small chip that transmits an indication from the key to the receiver module each time the key is used. If this signal does not match the one recorded by the car the immobilizer will shut down the engine and prevent the vehicle from starting. However, if the fob is not working and you can't reprogram it, it could be due a damaged chip.
The chip in the key fob is not permanent to the device and may need to be replaced in order to get it working again. This can be accomplished by getting the key fob removed from its housing and using pins or needles to contact each metal retaining clip. You'll require replacement if they are damaged or damaged by corrosion. Make sure that any replacement batteries are the same size, voltage, and specification as the original one.
