Picking double throw deadbolt

[linuxbz]

I bought a Phillips 715 IF deadbolt/latchbolt lock to practice on. I picked it, but then started thinking. In order to actually open this lock (assuming the deadbolt is fully thrown) you would have to rotate it over 720 degrees to pull back the latchbolt.

I seem to remember that if you pick a common cylinder lock and rotate it 180 degrees, pins can fall into the bottom of the keyway, right? That would present a problem. Even if that didn't happen, you'd have to pick it twice more when it reached the top.

I haven't used a plug spinner yet, but I'm guessing that might work, right? Are they designed for spinning over 720 degrees against some load (moving the deadbolt)?

Finally, I'm guessing this kind of lock might be easier to impression than to pick. Your thoughts?

If you rotated it 180 degrees with the key in the barrel, the pins would just ride over the bottom of the key. In my experience pins don't usually fall into the bottom of the barrel, but if they do it's just a matter of lifting them up while turning.

Plug spinners are usually designed to rotate 90 degrees, and not with load, so you would have to turn it, lift the pins, continue turning, use the plug spinner to jump over the chambers (or re-pick), etc.

Once you pick this lock, simply put your pick at the bottom of the keyway and turn the plug while keeping the pick on the bottom of the keyway and you shouldn't experience any issues with the pins trying to drop into the keyway.

The best plug spinner i've used to date (but don't own) is the FlipIt and it's good for doing exactly what you're talking about.

What type of cylinder is it ??

Plug spinner should to the job easy as
HPC make the best ones, expensive but worth it

Good Luck

use some cotton to solve the problem.

use some cotton to solve the problem.

eh???



And as said to stop the pins from falling into the broaching on the bottom of the plug hold your pick on the bottom of the lock so the top pins don't fall in, I have had locks not work after picking them and not doing this because master pins have fallen out and I haven't noticed, then when you get the key and try to open the lock it wont work so you will have to pull the lock apart to fix it.

Is this lock like the Gainsborough Tri-lock where the latch extends to deadlock?
