A couple of questions:

Are you _sure_ that you have the correct key.  In other words, did the 
locks work at one time with that key?

How long has it been since the lock has functioned?

Never put _oil_ in automotive locks.  I attracts dirt and grime to the 
tiny moving parts.

Geez!  I hope the vinegar didn't "eat anything up".

If it's been like that for a good while, first try drowning it with 
WD-40 and running the key in and out (rappidly) about a doezen or so 
times.  Then repeate a few times.  (Squirt - run key in and out - squirt 
- run key in and out). 

If this doesn't work or the key won't go in at all, remove the lock and 
soak it in WD-40 over night, then try it.  If _that_ doesn't work, the 
tumbler springs may be deteriorated to a point where they can no longer 
prform their intended tast of pushing the tumbler against the cuts of 
the key.  If that is the case they will need to be replaced.

I wouldn't advise disassebmle of the lock unless you know what you are 
doing.  Besides you probably wouldn't be able to get the springs any 
where but from a locksmith.  (Just about any foreign car tumbler spring 
can be made to work.)  The tumblers are another story, so if you _do_ 
take it apart, be carfull with them.

I can relate.
