Hi and welcome to 2CarPros.
Before I start, there is more than one component that can be causing this. You really need scan the computer to determine what is causing everything to remain locked. Regardless, here are the directions for the key cylinder lock tumbler. The attached pictures correlate with these directions.
Lock Cylinder
When disconnecting and connecting the Battery, the procedure must be followed as described in the repair information. Refer to=> [ Battery, Disconnecting and Connecting ].
Steering lock may be destroyed.
If steering lock is operated without lock cylinder, it locks and must be replaced.
Steering lock must not be operated without lock cylinder.
Removal
- Disconnect the battery. Refer to => [ Battery, Disconnecting and Connecting ].
- Remove the steering wheel.
- Remove the steering column trim.
- Remove the steering column electronic systems control module (J527). Refer to=> [ Steering Column Electronic Systems Control Module ] See: Steering Mounted Controls Communication Module > Removal and Replacement > Steering Column Electronic Systems Control Module (J527).
- Remove the airbag spiral spring/return spring with slip ring (F138). Refer to => [ Airbag Spiral Spring/Return Spring With Slip Ring ] See: Steering Mounted Controls Communication Module > Removal and Replacement > Airbag Spiral Spring/Return Spring With Slip Ring (F138).
- Remove the steering angle sensor (G85). Refer to => [ Steering Angle Sensor ] See: Steering Mounted Controls Communication Module > Removal and Replacement > Steering Angle Sensor (G85).
Switches must not be removed when removing lock cylinder.
The Anti-theft immobilizer reader coil (D2) is attached to the lock cylinder and cannot be replaced separately.

To improve clarity, the ignition key is not shown in the following illustration.
- Insert the ignition key into the lock cylinder - 1 - and turn to the "Drive" position.
- Use the steel wire - 2 - to release the securing lever - 3 - of the lock cylinder - 1 - - arrow -.
- Insert the lock cylinder - 1 - into the steering lock housing.
The Anti-Theft Immobilizer Reader Coil (D2) connection must be inserted into the guide on the steering lock housing.
- Remove the steel wire - 2 - from the lock cylinder - 1 - and then make sure the lock cylinder fit securely in the steering lock housing.
- Connect the connector to the anti-theft immobilizer reading coil.
Further installation is done in reverse order of removal.
Now, If an ignition key is replaced or another ignition key is required, the new ignition key must always be adapted to the immobilizer. Here are the directions for that. However, it does require VAS / VAG programing.
