There are a number of reasons that the key fob could not function properly, such as a dead coin battery or water damage, receiver module issues or signal interference. This article will walk you through the steps needed to get it working again.
Water Damage
If your seat alhambra keyfob is able to survive washing cycles or a bath in the ocean or pool then it probably has an incredible waterproof chip, but do not make it a habit as exposure to excessive water increases the chance of the key fob being damaged. If your key fob ceases to working after exposure to rain or clean tap water, you should remove the battery and clean the electronic component using a paper towel. Allow it to dry completely before replacing the battery. If the battery is exposed to soapy or salty water, it is recommended that you clean the chip with isopropyl alcohol or 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 that your receiver module has developed a fault. The good news is that it is a relatively simple and cost-effective fix. You can disconnect the 12 volt battery for about a couple of minutes (first remove the negative cable and press the horn button multiple times) to drain any residual electric current, then reconnect it in reverse order e.g. Positive cable first and then negative.
ESP Warning Light – If the ESP symbol blinks, it is normal. It indicates that you are driving on terrain that has poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly on, it indicates that there is a problem with the system. This can be identified by using an iCarsoft i908 seat OBD code reader kit. It will provide you with a an in-depth description of the fault.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not working is a dead battery. The key fob is powered by a small button-cell battery. Replace it with a new battery with 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 in good condition and free of corrosion.
If the key fob has been 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 before putting in the new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob isn't working after replacing the battery it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery, but it didn't perform, or stopped working suddenly your receiver module might have encountered a problem. The receiver module receives radio frequency signals from your key fob's remote and transforms them into electrical signals that are then processed by other modules in the car.
If the receiver module is defective it will not take any commands from your remote key fob. In this scenario it is necessary for a dealer to reprogramme your key fob as well as install an entirely new receiver.
The key fob comes with rubber seals that prevent water from entering the electronic chip inside. If you immerse the key fob into soapy or salty water, it could cause damage to the chip. You can try to clean the chip by rub it with isopropyl alcohol or electronic cleaner, but If your key fob isn't working after all this, you'll have to buy a new one.
If the keys are in a pair but the receiver module has developed a fault, you can try rebooting all of the onboard electronics by disconnecting the battery that is 12 volts for a short period of time. Then reconnect the battery in reverse order (negative cable first, then positive). This will reset the onboard electronic and restore their functionality.
Faulty electronic chip
The key fob comes with a tiny chip that transmits the signal from the key to the receiver module each time the key is used. If www.thekeylab.co.uk doesn't match that stored by the car the immobilizer will stop the engine and stop the vehicle from starting. If the key fob does not function and you are not able to reprogram it, it could be because of a faulty microchip.
The chip in the key fob is not a permanent part of the device, and might need to be replaced in order to get it working again. This can be done by getting the key fob removed from its housing and using pins or needles to contact each metal retaining clip. You will require replacement in the event of damage or corrosion-prone. Make sure that the replacement batteries have the same voltage, size and specifications as the original one.
