Newbie having trouble Picking Masterlock 40mm 1902D

[HillTJ]

Hi, this is my first post to the forum & I'm very keen to be involved! I bought myself a Peterson GSP Ghost lockpick set after reading reviews & it seems to be reported as a good beginner lockpick set. I hope that proves correct.

Anyway, I also bought the above-mentioned lock at a local hardware store as I was itching to get started. I've watched a bunch of videos & understand the picking principle (practice appears to be lacking). I can successfully open this lock by using bottom of plug tensioning & raking, but cannot single pick it. I have been trying for hours/days/weeks to no avail.

I think that I may be pushing the pins up too far with my pick, but have consciously tried not to and still no success. I've opened the lock by raking & had a look at the pins to get an idea how much they protrude.

Got to say, I don't feel that I get a positive "click" when a pin is set & am unsure as to how much pressure I need to use to set a pin.

Is this a bad lock to learn on? or is it just me?. I don't wish to be beaten but am getting frustrated. I have a smaller masterlock 103 which single picks too easily so is no challenge.

Appreciate any advice you can provide.

I had one of these kick my **** not long ago at work. A seemingly easy lock but it took forever!

Try varying the tension along with keeping the shackle partially depressed so its not holding the plug from turning on the back end.

Hi, thanks. Will give this method a go & let you know. Cheers

I picked 3 of these locks with a homemade pick.
Despite being a 4 pin lock, the key bitting can still pose a challenge if there's a mix of high and low cuts.
Keep trying. You'll get it eventually.
