My 04 D2 did soemthing new this AM. Got in, went to turn the ignition key and it would not move a millimeter. Jiggled it for over 5 minutes before it turned. Damn near missed my train Any thoughts or suggestions on how to prevent this in the future?

 

Try moving the steering wheel a little bit next time it happens while you turn the key.

 

A shot of graphite lube would probably help as well (in all locks...)

 

but if it doesn't turn then its seized up and needs to be replaced. What we do at the dealership is to replacee the cylinder from a locksmith. we take it out and send it to them and they install a new one and away we go. The trick to take it out is to remove the lower cover with a philips screwdriver and then take a long flat screwdriver and a hammer and bang the shear bolts out. you have to tap them to loosen then up. They originally had a head on them but they shear off at a specific torque for security feature. once they are loose you can disconnect the entire ignition switch at the fuse box and other two connectors and take it to a locksmith to get reset.

 

This had me in a fit just after buying my wife's 01 Disco. Move the steering wheel to the left a little while turning the key.

 

I let my wife drive my LR to the grocery store the first weekend I owned it... she proceeded to rip the remote off the key trying to remove it from the steering column. I came to the rescue with pliers and a tube of crazy glue, needing only to turn the steering wheel to release the key.

Discos will find a way to trick you... like putting buttons in weird places, placing bolts in locations no human being can reach without 3ft of extensions attached and two universal joints, ungreasable u-joints paired with a greasable u-joint on the same drive shaft, lots of drains that clog easily and flood the interior, and yes... not letting go of your key.
