Q: cant remove ignition lock assembly on 1996 Mercedes-Benz E320

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 1996 Mercedes E320 changed ignition, lock switch tumbler assembly and steering lock assembly.
drove the car for two days... parked car on a hill, now ignition key doesn't come out...or start vehicle...tried
adjusting cable on shifter assembly still no luck.
by the way shifter assembly seems to have a lot of play..
any help would be much appreciated.
