Water Damage

However, do not make it a habit as exposure to excessive water increases the chance of the key fob becoming damaged. If the key fob ceases to functioning after exposure to clean water from the tap or rain, just take out the battery, wipe the electronic component using a paper towel and allow it to dry completely before putting the battery back in. If the key fob has been exposed to soapy or salty water, it is recommended that you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock even after you've replaced the battery for the button, it is possible that the receiver module is suffering from a fault. The good news is that this is a simple and affordable fix, you can just remove the battery 12 volts for a few minutes (first take off the negative cable and then press the horn button a few times) to drain any residual electrical current and then reconnect it in reverse order e.g. Positive cable first, then negative.
ESP Warning Light – If the ESP symbol is illuminated, this is normal. It is a sign that you are driving over terrain with poor traction. This could be due to gravel, snow or surface water. If the ESP warning light is continuously blinking, it indicates that there is a glitch in the system. It is best to be diagnosed using a iCarsoft i908 Seat OBD Code Reader which will give you a specific fault description.
Dead Coin Battery
A dead coin battery is among the most common causes for the seat alhambra keys to cease to function. The key fob is powered by tiny button cell batteries that keeps it running. Replace it with a new battery that is 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 on the key fob are clean and corrosion-free.
If the key fob was exposed to water, like rain or soapy water, it's recommended that you remove the battery and clean the electronic chip using alcohol or an electronic cleaner prior to inserting the new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob is still not working after replacing the battery, it may be necessary to replace the entire key fob.
seat key replacement
If your key fob has stopped working after replacing the battery, but it did not help, or it just stopped working out of the blue The receiver module could have developed a fault. The receiver module receives radio frequency signals from your key fob's remote and converts them into electrical commands which are then used by other modules within the car.
If the receiver module has a problem it will not take any commands from your remote key fob. In this scenario, you will have to visit a dealer for reprogramming of your key fob and new receiver module.
The key fob is sealed with rubber to prevent water from getting inside the electronic chip. If you dip the key fob in soapy or salty water, it could cause damage to the chip. You can try to clean the chip by using isopropyl Alcohol to rub it or electronic cleaner, but If your key fob doesn't work after doing this, then you'll need to purchase a new one.
If the keys are paired but the receiver module has developed a fault, you can try rebooting all of the electronics on board by removing the battery at 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic circuits and restore their functionality.
A malfunctioning electronic chip
The key fob has an electronic chip that transmits a signal to the receiver module every time the key is used. If the signal doesn't match the one the car has stored the immobilizer will be disabled and prevent the vehicle starting. If the key fob does not work and you aren't able to reprogram it, this could be due to an issue with the microchip.
The chip in the key fob isn't an irreplaceable part of the device, and might need to be replaced to function again. The best way to do this is by removing the key from its housing and then using a pin or needle to get into contact with each of the metal clips that hold it. If these are corroded or broken, you will require replacement in order for the remote control to function. Make sure that any replacement batteries have the same voltage, size and specifications as the original.
