If I remember, Titan K locks are Croatian... the tolerances aren't very tight at all. If you can't rake it open it's either because the bitting is irregular, or you're just not doing it properly. In saying that, some locks are a pain to rake open even though they should be a piece of cake so who knows.
Anyway like I said, roll the pick gently and slowly from back to front and feel for binding... when you hit a binding pin it'll feel more solid than the rest, so get your pick right on the tip of that pin and push it slowly until it clicks into place.
Make sure to use as little tension as possible, you can use heavier tension to find the binding pin but you'll need to lighten it up for actually setting it otherwise you'll put unnecessary stress on the pick. Do this for each pin and get a feel for the lock, some will have nice clear binding and the pins will set crisply, others not so much... take your time and concentrate on each pin rather than just trying to get the lock open, soon enough you'll feel that satisfying pop as the last pin sets and the plug begins to turn.

Only other thing I can say is, if the lock suddenly turns a few degrees but doesn't open, then you're trapped in a false set - in which case, read up on picking spool pins and try again.
This is all easier said than done, but with enough practice you will get the hang of it.
