There are seat leon key fob programming why the key fob could not function properly, such as an inoperative coin battery, water damage to the receiver module or signal interference. This article will walk you through the steps to get it working.
Water Damage
If your seat alhambra key fob survives an wash cycle or bath in the ocean or pool then it probably has 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 ceases to functioning after being exposed to rain or clean tap water, take out the battery and wipe the electronic component using a towel. Dry it completely before replacing the battery. In case of exposure to salt or soapy water it is recommended to wash the chip with isopropyl alcohol or an electronic cleaner prior to attempting to put the battery back in.
Faulty Receiver Module
If you've tried the battery of a button cell and the key fob doesn't lock or unlock then it's likely that the receiver module has developed a fault. It's a simple and cheap fix. You can unplug the battery with 12 volts for a couple of minutes (first remove negative cable, then press the horn a few times) in order to drain any remaining power. Then, reconnect it in reverse. Positive first followed by negative.
ESP Warning Light - If the ESP symbol flashes, this is normal. It indicates that you're driving on terrain with poor traction. This could be due to snow, gravel or surface water. If the ESP light is constantly on, it means that there is a fault in the system. It is possible to identify the problem with a iCarsoft i908 seat OBD code reader kit. It will provide detailed information about the fault.
Dead Coin Battery
A dead coin battery is one of the most frequent reasons for the seat alhambra keys to stop working. The key fob is powered by a tiny button-cell battery. It should be replaced with a new one that has exactly the same size, voltage, and specification as the original. If you're replacing the battery, ensure that you remove all metal clips from the back of the key fob. You should also ensure that the contacts are 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 with an electronic cleaner or isopropyl alcohol prior to installing a new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob is still not working after replacing the battery, it might be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob has stopped working after you replaced the battery and it didn't help, or it suddenly stopped working in a sudden manner it is possible that your receiver module could have developed an issue. The receiver module receives radio frequency signals from the remote keyfob and transforms them into electrical signals that are then followed by other modules within the car.
If the receiver module is defective, it will not accept any commands from your remote key fob. In this situation the dealer will have to reprogram your key fob as well as install an entirely new receiver.
The key fob has rubber seals to prevent water from getting into the electronic chip inside. If you immerse your key fob into the ocean's salty or soapy water, the chips inside may be damaged. If your key fob isn't able to work, you can try cleaning the chip with isopropyl or electronic cleaner.
If the keys have been successfully paired, but your receiver module is not working, you can try to restart all of the electronics on board by disconnecting the battery at 12 volts for few minutes. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset the on-board electronic and restore their functionality.
Faulty Electronic Chip
The key fob is outfitted with a tiny chip that transmits the signal 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 stop the vehicle from starting. If the key fob doesn't work and you are unable to reprogram it, it could be due to a malfunctioning microchip.
The chip in the key fob isn't permanent to the device and could need to be replaced in order to make it work again. This can be accomplished by getting the key fob removed from its housing, and then using a needle or pin to make contact with each metal retaining clip. You will need to replace these in the event of damage or damaged by corrosion. Make sure that any replacement batteries are the same size, voltage, and specification as the original one.
