There are many reasons that the key fob may not function properly including dead coin battery, damage to the receiver module, water problems or signal interference. This article will walk you through the steps to make it work again.
Water Damage
If your seat alhambra keyfob is able to survive the wash cycle or a bath in the ocean or pool then it probably has an amazing waterproof chip. However, be careful not to make this a routine because exposure to water in excess increases the risk of the key fob becoming damaged. If the key fob stops 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 let it dry completely before putting it back into. If the key fob was exposed to salty or soapy water it is recommended you clean the chip with isopropyl or electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after having replaced the button cell battery It is possible that the receiver module is suffering from a fault. The positive side is that this is a relatively simple and inexpensive repair, you can simply disconnect the battery for about a couple of minutes (first remove the negative cable then press the horn button several times) to eliminate any remaining electric current, then reconnect it in reverse order e.g. positive cable first and then negative cable later.
ESP Warning Light - If the ESP symbol is illuminated, 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 continues to be shining, it is a sign that there is a fault within the system. It should be detected using an iCarsoft i908 Seat OBD Code Reader kit that will provide you with a specific fault description.
Dead Coin Battery
A dead battery for the coin is one of the most frequent reasons for the seat alhambra keys to cease to function. The key fob is powered by a tiny button-cell battery. Replace it with a brand new battery that is the same dimensions, voltage and specs 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 clean and corrosion-free.
If the key fob has been exposed water, like rain or soapy water it is recommended to remove the battery and clean the electronic chip using alcohol or an electronic cleaner prior to installing the new battery. The chip could be permanently damaged by moisture. If the key fob still not working after replacing the battery, it might be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob has stopped working after replacing the battery but it did not perform, or suddenly stopped working the receiver module could have experienced a malfunction. The receiver module is able to receive radio frequency signals from your key fob's remote and transforms them into electrical signals which are then used by other modules in the car.
If the receiver module has suffered a malfunction it will not respond to any of the commands transmitted by your remote key fob. In this instance you'll be required to visit a service for reprogramming of your key fob and a new receiver module.
The key fob is covered by rubber to block water from getting inside the electronic chip. If you submerge the key fob into salty or soapy water, it could damage the chip. You can try cleaning the chip by rub it with isopropyl alcohol or electronic cleaner, however in the event that your key fob isn't working after all this, then you'll need to purchase a replacement.
If the keys are in a pair but the receiver module has developed a fault, you can try restarting all of the onboard electronics by disconnecting the battery with 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first, then positive). This resets all the electronic components onboard and restore their functionality.
Electronic Chip Faulty
The key fob is equipped with a tiny chip which transmits an indication from the key to the receiver module every time the key is used. If this signal does not match that stored by the car the immobilizer will shut down the engine and prevent the vehicle from beginning. If the key fob doesn't work and you aren't able to reprogram it, it could be due to a faulty microchip.
The chip in the key fob isn't permanent to the device, and might need to be replaced in order to get it working again. The most effective method for doing this is by removing the key from its housing and then using a pin needle to connect with each of the clips made of metal. You'll need to replace these if they are damaged or damaged by corrosion. Make sure any replacement batteries have the same voltage, size, and specification as the original.
