Okay so I've tried picking my first lock with no avail and after a little looking around I've discovered that the lock may have security pins in (not 100% as the person didn't gut it). It's a 40mm £5 lock I bought from Wilkinsons (UK based store) and I was wondering if someone who has picked/gutted it could tell me if it's got security pins or I just fail at picking standard pins.

P. S. I would buy a cutaway lock (I think it's called that) where you can see the pins as you pick, for practice, but since I'm 15 I don't have a decent way to make money and since its Christmas soon I'm just getting one then.
