im new here so 1st id like to introduce myself

im stuart, new to lockpicking, it just one of those skills u wana have

got a small southord set last week with tention wrench, hook, half damond, ball and snake (think thats rite).
i can only practice on our front door becasue its the only tumbler lock in the house and its abit strange becasue the pins will lock one way and not the other. the annoying this is the other side in the way it needs to turn to unlock :S
its one of those doors that u have to lift up the handle before u can lock it. basically what i meen is if its locked, and i put the key in it will turn clockwise about 160o then gets stuck, i have mannaged to pick it seveal times to do this but its no use because its not ment to unlock that way. and if i then the key the other direction it will unlock, but if i try and pick it most of the pins wont lock into place, so i can pick it to lock the door, but not unlock it. :S
i am new so im not very good at it yet, i tend to screw it up 80% of the time i pick it, only been successfull about 4 times but havent actually been able to unlock it yet :S
can anyone gimme some help and advice?
thanks
Stu
