I'm also having some trouble with the blurry photos -- but the H-shaped keyway looks something like a right-handed version of a Codem cylinder (French manufacturer). Unlike a usual "dimple" key, the Codem keys have ridges that extend above the surface of the key, in order to raise the pins. You'll likely find five regular pins, protruding up from the bottom-right side of the keyway, and no profile control pins. If that's the case, then you'll need small picks to navigate the reduced area in the keyway -- but it shouldn't require any unfamiliar tools or techniques.
Having said all that,
please do not pick this lock if it is in use.
I cannot be sure, from the pictures alone, what type of lock this is... and several dimple-style locks have a habit of dumping their drivers and/or springs into the keyway if they're picked and rotated without a key in place.
and a cisa key lock 
.Can you help to choose the right tools?
To pick a lock you should identify it and learn the operating principles of the lock to pick it succesfully
