There are many reasons that the key fob may not function properly including dead coin battery or damage to the receiver module, water issues or signal interference. This article will guide you through the steps necessary to fix it.

Water Damage

If your key fob for the seat alhambra survives an wash cycle or a dip in the ocean or in a pool, then it has a waterproof chip. But, you shouldn't do this often since prolonged exposure to water increases the likelihood of the key fob getting damaged. If your key fob stops functioning after being exposed to rain or clean tap water, remove the battery and wipe the electronic component using a paper towel. Dry https://www.thekeylab.co.uk/seat-car-keys/ before replacing the battery. In case of exposure to salt or soapy water it is recommended to clean the chip using isopropyl alcohol or a electronic cleaner prior to attempting to put the battery back in.

Faulty Receiver Module

If you have tried the battery of a button cell and the key fob still cannot be locked or unlocked, it's likely the receiver module has been faulty. The positive side is that this is a fairly easy and inexpensive repair, you can disconnect the battery for just a few minutes (first take off the negative cable then press the horn button several times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive first, then negative.

ESP Warning Light - If the ESP symbol flashes, this is normal. It indicates that you are driving on a terrain with poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly on, it is a sign that there is a flaw in the system. It is possible to identify the problem with a iCarsoft i908 seat OBD code reader kit. It will provide an in-depth description of the fault.

Dead Coin Battery

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

If the key fob was exposed to water (such as soapy or rain tap water) it is recommended to remove and clean the chip using an electronic cleaner or isopropyl alcohol before installing a brand new battery. The chip may be permanently damaged by water. If the key fob is 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 and it did not help, or if it suddenly stopped working without notice the receiver module may have developed a fault. The receiver module takes the radio frequency signals from your key fob's remote and transforms them into electrical signals that are then followed by other modules inside the car.

If the receiver module has developed a fault that prevents it from responding to any of the commands transmitted by your remote key fob. In this situation, you will be required to visit a service for reprogramming of your key fob and a new receiver module.

The key fob is encased with rubber to stop water from entering the electronic chip. If you immerse your key fob into soapy water or salty ocean water, the chips inside could be damaged. If your key fob doesn't function, you can try cleaning the chip using isopropyl or an electronic cleaner.

If the keys have been connected, but the receiver module is faulty, you can try to restart all the electronics in the board by disconnecting the battery with 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.

Electronic Chip Faulty

The key fob has tiny electronic chips that sends a signal to the receiver module each time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer is disabled and prevent the vehicle from starting. However, if the fob is not working and you cannot reprogram it the issue could be due to a faulty chip.

The chip inside the key fob is not a permanent part of the device and might have to be replaced to get it working again. The most effective method for doing this is by removing the key from its housing and using a pin needle to contact each of the retaining clips made of steel. If the clips are corroded, or broken, you will require replacement in order for the remote control to work. Make sure the replacement batteries are of the same voltage, size and specifications as the original.
