Key won´t turn following auto gearshift replacement

My father has a 2002 S320 in which the car became stuck in Park. A recovery guy came and knocked it into neutral where it remained with the key in the ignition and he was told to leave it like that. I then found several videos showing this to be a common problem so I removed the shift mechanism and successfully removed the the broken plastic lever and ordered a new aluminum one from the States. Meanwhile I put the mechanism back in (without the over as shown on various Youtube videos as it would appear that some people don´t bother to maintain the Park lock) and the shifter moves freely into any gear (albeit at the moment without the safety of the Park feature/key removal disabled). The black release cable is correctly connected as it came out and I have manually pressed on this and can see the key wiggle slightly this confirms it is still correctly connected at the EIS.

I accidentally took the optical key out and now find that I cannot turn the key to turn on the power, ignition or crank the engine. I have tried all sorts of things but it will not turn. The battery became drained so I am using a jump charger each time to feed the battery with power. I also note that the steering wheel has not locked and I believe this may be related but I thought I would ask here in case I make things worse by trying to lock it and perhaps enabling a reset of the key turning facility.

Can anyone help?!!

Read ALL of our stickies before posting, especially the New Guy Sticky.

W220 does not have a Steering lock.

The shifter is part of the Theft Relevant Parts on the Car, (Immobiliser System).

You've just got to re trace your steps to see what went wrong, in particular make certain that all the Wiring Plugs are properly inserted.

Thank You for completing your profile.

Yes, you must make sure that the battery is 100% a weak battery will cause all kinds of grief.

The Key interlock is as @Witek_M says, purely mechanical.

Next question after replacing or fully charging the battery ...................

Does the Key insert and turn, and when turned are you getting any Dash Lights up as would normally happen upon turning ignition on ??????????????????????

HTH ;)
