Steering wheel lock - Clarification

[NullNullson]

So I can't seem to lock my steering wheel on my 04 350z GT.  The car is a relatively new purchase and i'm new to these cars in general.  So i'm just going through all the apparent issues I have on it so far.

 

I have read a few threads about the 370's steering getting stuck.  But i'm not sure if the 350's suffer the same fate.  So curious if a previous owner has done something to prevent this happening.  Can anyone give me advise on what I should be looking for?  Is this a problem with the steering collum potentially?

 

Any advise is appriciated.  Apologies for the vague details.
