Reprogramming the key of the Opel Astra model G after replacing the battery is a procedure that can be done in three simple steps. The first step is to insert the key into the ignition switch and turn on the instrument panel only.

The second step is to press the vehicle's lock button while the key is still in the ignition for a few seconds. The third step is to release the button and turn on the vehicle.

Now your key should be reprogrammed; if the problem persists and the vehicle still does not recognise the key, visit a workshop.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
