There are many reasons why the key fob may 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 needed to get it back in working order.
Water Damage
If your seat alhambra key fob can withstand an wash cycle or bath in the pool or ocean then it's probably equipped with an incredible waterproof chip, but be careful not to make this a routine because exposure to water in excess increases the chance of the key fob getting damaged. If your key fob ceases to functioning after exposure to rain or clean tap water, remove the battery and wipe the electronic component with a towel. Dry it completely before replacing the battery. In the event of exposure to soapy or salty water it is recommended that you clean the chip with isopropyl alcohol or an electronic cleaner prior to attempting to insert the battery back in.
Faulty Receiver Module
If you've tried an entirely new battery for your button and the key fob cannot be locked or unlocked, it is likely that the receiver module has been faulty. The positive side is that this is an easy and affordable fix, you can just remove the battery 12 volts for just a few minutes (first remove the negative cable, then press the horn button a few times) to drain any residual electric current, then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light - If the ESP warning light flashes, this is normal and means that the car is driving on terrain in which the traction between the road surface and the tyres is not ideal such as gravel, snow or a lot of surface water. If the ESP warning light continues to be blinking, it indicates that there is a fault within the system. It is best to be diagnosed using a 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 key not working is a dead coin battery. The key fob comes with tiny button cell batteries which keeps it powered. Replace it with a brand new battery that has the exact 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, such as soapy or rain it is recommended to take the battery off and clean the electronic chip with isopropyl alcohol or a electronic cleaner prior to installing the new battery. The chip could be permanently damaged by moisture. If the key fob does not work after replacing the battery it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery but it didn't work, or if it stopped working abruptly, your receiver module could have experienced a malfunction. The receiver module is able to receive radio frequency signals from your remote keyfob and converts them into electrical commands that are then processed by other modules in the car.
If the receiver module is faulty and is not able to take any commands from your remote key fob. In this scenario you'll need to go to a dealer for reprogramming your key fob and a new receiver module.
The key fob has rubber seals to prevent water from entering the chip inside. If you immerse your key fob into salted or soapy ocean water, the chip inside could be damaged. You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, but If your key fob isn't working after all this, then you'll need to purchase a replacement.
If the keys are connected but the receiver module has developed a fault you can try restarting all of the electronics on board by removing the 12 volt battery for a short period of time. Then, reconnect the battery in reverse order (negative cable first, then positive). This will reset the on-board electronic circuit and restore their functionality.
Faulty Electronic Chip
The key fob is equipped with a small chip that transmits a signal from the key 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 turn off and stop the vehicle from starting. If the key fob you purchased does not work and you are unable to reprogram it, this could be because of an incompatible microchip.
The chip in the key fob may need to be changed to make it work again. The best way to do this is by removing the key from its housing and then using a pin or needle to make contact with each of the metal retaining clips. If these clips are damaged or broken, you will need to replace them to allow the remote control to function. Make sure that the replacement batteries are of the same voltage, size and specification as the original.
