I'd say a person who has intimate knowledge of a lock or mechanical part should be able to use their telekinetic prowess to manipulate its inner workings. Of course, that requires them to have the skill necessary and the studying required for it. The same as a lock picker would, really.

As someone who picks locks, it's not that difficult, at least the goal isn't. What you're doing is simply lifting the pins to their specific hight so that the lock can be turned. That's what the grooves on your key are there for. A universal part in a lock picking set called a rake, is pushed in and out, bouncing the pins until the torsion wrench (the s shaped thingy that turns the lock once the pins are in place) can twist it successfully to the unlock position. Of course, unless it's locked from both sides this could be sidestepped (pending Aeonnumbera's approval) simply by turning the lock from the other side.

If this is telekinesis dude, why not just accelerate a rock towards the offending lock?

Why pick locks when you can remove the door?

Because I figure I need something else to add to my arsenal when there are people who can create knives out of nothing and turn into light.
