Dead Coin Battery
One of the most frequent reasons for the seat alhambra key to stop working is a dead coin battery. The key fob has a tiny button cell battery that keeps it running. It should be replaced with a new one that is identical in size, voltage and specifications as the original. If you're replacing your battery, ensure that you remove all metal clips from the back of the key fob. Also ensure that the contacts are free of corrosion.
If the key fob was exposed to water, such as soapy or rain, it's recommended that you remove the battery and clean the electronic chip with alcohol isopropyl or an electronic cleaner prior to inserting the new battery. The chip is sensitive to moisture and can be permanently damaged. 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 didn't help, or if it stopped working completely without notice The receiver module could have developed an issue. The receiver module is responsible for capturing the radio frequency signals sent by your remote key fob and converting them into electrical commands which are then processed by other modules in your car.
If the receiver module is faulty and is not able to take any commands from your remote key fob. In this case the dealer will have to reprogramme the key fob as well as install an entirely new receiver.
The key fob is fitted with rubber seals to prevent water from getting into the electronic chip inside. If you immerse the key fob in salty or soapy water it could cause damage to the chip. If your key fob doesn't work, you could try cleaning the chip with isopropyl or electronic cleaner.
If the keys have been successfully paired, but your receiver module is not working it is possible to restart all the electronics that are on board by disconnecting the battery with 12 volts for a couple of minutes. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset the onboard electronic and restore their functionality.
Faulty electronic chip
The key fob is equipped with a small electronic chip that sends a signal to the receiver module each time the key is used. If the signal isn't in line with the one the car has stored the immobilizer will be disabled and stop the vehicle from starting. However, if the fob is not working and you cannot reprogram it this could be due a damaged chip.
The chip inside the key fob may need to be replaced to make it work again. The most effective method for doing this is by removing the key from its housing and using a pin needle to connect with each of the metal retaining clips. You will have to replace them when they're damaged or damaged by corrosion. Make sure that the replacement batteries are the same size, voltage and specifications as the original one.
