There are many reasons why your key fob might not work properly including dead coin battery water damage, receiver module issues or signal interference. This article will walk you through the steps needed to make it work again.

Water Damage

If your seat alhambra key fob can withstand an wash cycle or bath in the pool or ocean it's likely to have an amazing waterproof chip. However, do not use it regularly because prolonged exposure to water increases the risk of the key fob being damaged. If the key fob ceases to working after exposure to clean tap water or rain, simply take out the battery, wipe the electronic component with a paper towel and let it dry completely before putting the battery back in. If the key fob has been exposed to soapy or salty water it is recommended you clean the chip using isopropyl or electronic cleaner.

Faulty Receiver Module

If the key fob will not lock or unlock after having replaced the battery for the button, it is possible that the receiver module is suffering from an issue. It's a relatively simple and cheap fix. You can unplug the 12 volt battery for a few minutes (first remove the negative cable, then press the horn a few times) to eliminate any remaining power. After broken seat car key , you can reconnect it in reverse. Positive first and then negative.

ESP Warning Light – If the ESP symbol flashes, this is normal. It is a sign that you are driving on terrain with poor traction. This could be due to snow, gravel or surface water. If the ESP light is always on, it is a sign that there is a fault in the system. It can be detected with a iCarsoft i908 seat OBD code reader kit. It will provide a detailed fault description.

Dead Coin Battery

A dead coin battery is among the most frequent reasons for the seat alhambra keys to stop working. The key fob is powered by a tiny button cell battery that keeps it powered. Replace it with a new battery with the same dimensions, voltage and specs as the original. When replacing the battery on the key fob, remove all metal clips and ensure that the contacts on the key fob are clean and free of corrosion.

If the key fob was exposed to water, like soapy or rain, it's recommended that you remove the battery and clean the electronic chip with alcohol or an electronic cleaner before putting in the new battery. The chip can be permanently damaged by moisture. If the key fob is still not working after replacing the battery, it could be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped working after replacing the battery, but it didn't help, or it suddenly stopped working without notice, then your receiver module could have developed an issue. The receiver module is responsible for capturing the radio frequency signals sent by your remote key fob and changing them into electrical signals that are then used by other modules in the car.

If the receiver module is damaged it will not be able to accept any commands from your remote key fob. In this case you'll be required to visit a service to reprogramme your key fob as well as a new receiver module.

The key fob features rubber seals that block water from getting into the chip inside. If you immerse the key fob into salted or soapy water it may damage the chips. If your key fob won't work, you could try cleaning the chip with isopropyl or an electronic cleaner.

If the keys have been paired but the receiver module has developed a fault you can try rebooting all of the electronics on board by disconnecting the battery at 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset the onboard electronic and restore their functionality.

Electronic chip that is malfunctioning

The key fob houses an electronic chip that sends a signal to the receiver module every time the key is used. If the signal isn't in line with the one the car has stored, the immobilizer will disable and prevent the vehicle starting. If the key fob doesn't work and you are unable to reprogram it, this could be because of an incompatible microchip.

The chip inside the key fob may have to be replaced in order to get it working again. The best method to do this is to remove the key from its housing and then using a pin or needle to connect with each of the retaining clips made of steel. If they are corroded or broken, you will require replacement in order for the remote control to work. Make sure any replacement batteries are of the same size, voltage, and specification as the original.
