If you've tried a new button cell battery and the key fob does not lock or unlock, it's likely that the receiver module has developed a fault. It is a relatively easy and affordable fix.

After that, you can reconnect it in reverse. positive cable first, then negative cable later.

Dead Coin Battery

One of the most common reasons for the seat alhambra key not working is a dead coin battery. The key fob is powered by a small button cell battery that keeps it running.

When replacing the battery on the key fob, remove all metal clips and ensure that the contacts of the key fob are free of corrosion and clean.

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 alcohol isopropyl or an electronic cleaner prior to inserting the new battery.

If your key fob has stopped working after replacing the battery but it didn't work, or if it stopped working in a sudden manner, your receiver module could be experiencing a problem. The receiver module is able to receive radio frequency signals from your remote keyfob and transforms them into electrical signals which are then used by other modules in the car.

If the receiver module is damaged it will not take any commands from your remote key fob. In this instance you will require a dealer to reprogram your key fob as well as install an entirely new receiver.

The key fob is encased with rubber to stop water from getting into the electronic chip. If you immerse the key fob in salty or soapy water, it may damage the chips. You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, however in the event that your key fob isn't working after this, you'll have to buy a new one.

If the keys are successfully paired, but your receiver module is not working, you can try to restart all the electronics in the board by disconnecting the battery at 12 volts for few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.

Faulty Electronic Chip

The key fob is fitted with a chip that transmits an indication from the key to the receiver module each time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer will turn off and prevent the vehicle from starting. However, if the fob is not working and you cannot reprogram it then it could be due to a defective chip.

The chip in the key fob may need to be altered to make it work again. This can be done by getting the key fob removed from its housing, and using a needle or pin to contact each metal retaining clip. You'll require replacement in the event that they have been damaged or corrosion-prone. Make sure that the replacement batteries have the same size, voltage, and specifications as the original one.
