There are a myriad of reasons why your key fob could not function properly, such as a dead coin battery damage to the receiver module, water issues, or signal interference. This article will walk you through the steps necessary to fix it.
Water Damage
If your seat alhambra keyfob is able to survive a wash cycle or a bath in the ocean or pool then it is likely to have an incredible waterproof chip, but do not make it a habit because exposure to water in excess increases the chance of the key fob becoming damaged. If the key fob stops functioning after exposure to clean water from the tap or rain, simply take out the battery, wipe the electronic component with a paper towel and allow it to dry completely before putting the battery back in. If the key fob has been exposed to salty or soapy water it is recommended that you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If you've tried a new battery for a button and the key fob doesn't lock or unlock then it's likely that your receiver module has found a fault. The good news is that this is a relatively simple and cost-effective fix. You can just disconnect the 12 volt battery for a few minutes (first remove the negative cable and then press the horn button multiple times) to remove any remaining electrical current and then reconnect it in reverse order e.g. Positive cable first and then negative.
ESP Warning Light - If the ESP warning symbol flashes this is normal and signifies that the vehicle is driving on terrain where the traction of the road surface and the tyres is not ideal like gravel, snow or lots of surface water.

Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop functioning is a dead coin battery. The key fob has tiny button cell batteries which keeps it powered. 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 on the key fob are clean and corrosion-free.
If the key fob was exposed to water, such as rain or soapy water 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 still isn't working after replacing the battery it could be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it did not function, or stopped working abruptly, your receiver module could be experiencing a problem. The receiver module is responsible for capturing the radio frequency signals that are sent by your remote key fob and changing them into electrical signals that are then utilized by other modules in your car.
If the receiver module has suffered a malfunction it will not respond to any of the commands issued by your remote key fob. In this case you'll need to go to a dealer to reprogramme your key fob and new receiver module.
The key fob has rubber seals that stop water from entering the chip inside. If you immerse the key fob in salty or soapy water, the chip inside could be damaged. If your key fob isn't able to work, try cleaning the chip with isopropyl or electronic cleaner.
If the keys are paired but the receiver module has developed a fault, you can try restarting all the on-board electronics by removing the battery that is 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic circuit and restore their functionality.
Faulty electronic chip
The key fob contains a small electronic chip that transmits a signal to the receiver module when the key is used. If the signal received does not match the one stored by the car the immobilizer will stop the engine and stop the vehicle from beginning. If the key fob doesn't function and you are not able to reprogram it, it could be because of an incompatible microchip.
The chip inside the key fob isn't a permanent part of the device and could need to be replaced in order to get it to work again. This can be done by taking the key fob out of its housing and using a needle or pin to connect with each metal retaining clip. You will require replacement in the event of damage or corroded. Make sure that the replacement batteries have the same voltage, size and specification as the original one.
