If your key fob for the seat alhambra survives a wash cycle, a dip in the ocean or a pool then it's equipped with a waterproof chip. However, don't do it often, as prolonged exposure to water increases the likelihood of the key fob becoming damaged. If your key fob ceases to functioning after being exposed to rain or clean tap water, you should remove the battery and wipe the electronic component with a paper towel. Let it dry completely before replacing the battery. In the event of exposure to soapy or salty water, it is recommended to clean the chip using isopropyl alcohol or a electronic cleaner prior to attempting to insert the battery back in.

Faulty Receiver Module

If the key fob does not lock or unlock even after you've replaced the battery of the button, it is possible that the receiver module has an issue. The good news is that it is a relatively simple repair that is inexpensive, you can just remove the battery 12 volts for just a few minutes (first take off the negative cable and press the horn button several times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive cable first followed by negative.

Dead Coin Battery

One of the most common reasons for the seat alhambra key to stop working is a dead battery. The key fob is powered by a tiny button-cell battery. It is recommended to replace it with a replacement with the same voltage, size, and specification as the original. When replacing the battery on the key fob, remove all metal clips and ensure that the contacts of the key fob are clean and corrosion-free.

If the key fob has been exposed to water, like rain or soapy water, it's recommended that you take the battery off and clean the electronic chip with alcohol isopropyl or an electronic cleaner before putting in the new battery.

Faulty Receiver Module

If your key fob stopped working after replacing the battery and it didn't help, or if it suddenly stopped working without notice the receiver module might have developed a fault. The receiver module takes the radio frequency signals from your key fob's remote and converts them into electrical commands which are then acted upon by other modules in the car.

If the receiver module has a problem it will not take any commands from your remote key fob. In this instance you'll be required to visit a service to reprogram your key fob as well as a new receiver module.

The key fob is covered by rubber to block water from getting inside the electronic chip. If you immerse the key fob in salty or soapy water, it could damage the chip. You can try to clean the chip by applying isopropyl alcohol or electronic cleaner, however should your key fob does not work after this, then you'll need to buy a new one.

If the keys are paired but the receiver module has developed a fault, you can try to reboot all of the onboard electronics by disconnecting the battery at 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuits and restore their functionality.

Electronic Chip Faulty

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 the signal isn't in line with the one the car has stored the immobilizer will be disabled and prevent the vehicle from starting. If, however, the key fob is not working and you are not able to reprogram it the issue could be due a damaged chip.

The chip inside the key fob might need to be replaced in order to make it function properly. This can be done by getting the key fob removed from its housing and using pins or needles to make contact with each metal retaining clip. You will have to replace them if they are damaged or damaged by corrosion. Make sure that the replacement batteries are the same size, voltage, and specification as the original.
