There are a variety of reasons why the key fob could not work properly, including the battery being dead, water damage to the receiver module or signal interference. This article will guide you through the steps to get it working again.
Water Damage
If your key fob for the seat alhambra can withstand the wash cycle or a dip in an ocean or a pool then it's got a waterproof chip. But, you shouldn't do this often because prolonged exposure to water increases the chance that the key fob will be damaged. If the key fob ceases to working after exposure to clean water from the tap or rain then simply remove the battery, clean the electronic component using a paper towel and allow it to dry completely before putting the battery back into. If the key fob was exposed to salty or soapy water it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after you've replaced the battery of the button it could be that the receiver module has a fault. It's a relatively simple and cheap fix. You can unplug the battery that is 12 volts for a couple of minutes (first remove negative cable, then press the horn numerous times) to remove any remaining power. Then connect it in reverse. Positive cable first followed by negative.
ESP Warning Light If the ESP symbol flashes, this is normal. It means that you're driving on terrain with poor traction. This could be caused by snow, gravel or surface water. If the ESP warning light remains flashing, it means there is a problem within the system. It is best to be identified using an iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop working is a dead battery. The key fob is powered by an insignificant button cell battery that keeps it running. It should be replaced by a new battery that is identical in 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. Also, ensure that the contacts are clean and free of corrosion.
If the key fob has been exposed to water, such as soapy or rain, it's recommended that you take the battery off and clean the electronic chip using alcohol isopropyl or an electronic cleaner prior to installing the new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob still not working after replacing the battery, it may 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 if it just stopped working out of the blue it is possible that your receiver module could have developed a fault. The receiver module receives the radio frequency signals from your key fob's remote and converts them into electrical commands which are then acted upon by other modules within the car.
If the receiver module is damaged, it will not accept any commands from your remote key fob. In this situation, you will need to go to a dealer for reprogramming of the key fob, and also a new receiver module.
The key fob is covered by rubber to block water from getting into the electronic chip. If you immerse the key fob in soapy or salty water, it may damage the chips. If your key fob does not work, try cleaning the chip with isopropyl or electronic cleaner.
If the keys are in a pair but the receiver module has developed a fault you can try to reboot all of the electronics on board by disconnecting the 12 volt battery for a short period of time. Then, reconnect the battery in reverse order (negative cable first followed by positive). This resets all the electronic components onboard and bring them back into operation.
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 thekeylab does not match the one that the car has stored the immobilizer is disabled and prevent the vehicle starting. If the key fob doesn't work and you are unable to reprogram it, it could be because of an issue with the microchip.
The chip in the key fob isn't permanent to the device and could need to be replaced in order to get it working again. This can be done by taking the key fob out of its housing and using a needle or pin to connect with each metal retaining clip. If the clips are corroded, or broken, you will require replacement to allow the remote control to work. Make sure that the replacement batteries have the same voltage, size and specifications as the original.
