A Beginner’s Guide to Tubular Lock Picking

by April 4, 2013 04/4/13

One of my personal goals for 2012 was to learn tubular lock picking and become proficient enough to share my knowledge with everyone here on ITS Tactical. It took me a few more months than I would have liked, but today I’ll be walking you through how to pick tubular locks.

Tubular Lock Picking 001

Tubular locks are commonly found on small gun safes, vending machines, computer locks, etc. In fact, what prompted me to get into tubular lock picking, other than for Locksport purposes, was when my son lost his key to a small handgun safe he was using for his Airsoft pistol.

Commonly thought to be more secure and more resistant to picking than standard pin and tumbler locks, I’ve found that with the help of a tubular lock pick, they’re much easier and faster to pick.

Tubular Locks

If you’re familiar with past discussions we’ve had on ITS, you’ll hopefully know what I mean when I refer to pin and tumbler locks, the kind you commonly find on your front door. Tubular locks are very similar to pin and tumbler locks and are actually a tubular pin-tumbler lock. Also known as Ace locks, axial pin-tumbler locks and radial locks.

All the features of a standard pin-tumbler lock are still there, just configured in a circular pattern rather than inline as standard pin-tumbler lock is. In fact, while the purpose of this post is to explain tubular lock picks, specifically built for picking tubular locks, they can also be picked with common single-pin picking. Only with a lot more effort.

As you’ll notice in the photo of the tubular lock pick trainer above, you have the spring, key pins (red) and driver pins (gold). This is also represented in the diagrams below as (red) key pins and (blue) driver pins.

Each complete pin stack is pushed with help from it’s spring towards the front of the lock. This binds the shear line and prevents the plug from turning (colored yellow in the diagrams.) The difference with a tubular key and a standard key is that instead of the cuts of a key, a tubular key has half-cylinder indentations with map to the height of the pin stack. It also means that duplicating a tubular key requires different machinery.

The top center of the interior of a tubular key features a raised protrusion that aligns the key in it’s proper configuration to map to each pin-tumbler stack. When the key is inserted, those mapped heights align, causing the shear line to separate and allow the plug to turn from the outer shell (green in the diagram below.)

Tubular Lock Picks

Standard configurations for tubular lock picks are 7 pin, 8 pin and the less common 10 pin. Some tubular locks are even six pins and while I haven’t personally tried it, the 7 pin tubular lock pick should work on the 6 pin lock. I suspect this is the case, as I’ve used an 8 pin tubular lock pick to pick “some” 7 pin tubular locks.

Tubular Lock Picking 002

The parts of a tubular lock pick include independent needles that correspond with each independent pin stack. These needles are held under tension with the use of the rotating collar.

Below the needles, but before the handle, there’s a washer that facilitates resetting the tubular lock pick. This brings us to the first step in using a tubular lock pick.

  1. Ensure the needles are free and can move independently and loosen the collar to the point where it’s just barely finger tight to apply light tension to the needles.
  2. Extend all the needles by pressing the washer to move them beyond the end of the pick.
  3. Press the complete pick against a hard surface to reset the needles to their baseline height.
  4. Insert the pick into the lock slowly, allowing the picking needles to map to the corresponding pin stacks.
  5. Slowly apply left to right turning torque to the pick and the lock should pop open.
  6. Once the lock is picked, remove the tubular lock pick and tighten the collar.
  7. *See the YouTube Video embedded above for a walkthrough of these steps.*

Now comes the amazing part. With the collar tightened down, you now hold a key in your hand that will open the tubular lock over and over again. With a tubular lock decoder you can actually measure the height of each pin as is corresponds in a clockwise pattern around the tubular lock pick. With that “code” you can have a locksmith create a duplicate key. That, or you can take your now decrypted tubular lock pick to a locksmith and have them reproduce a key.

Tubular Lock Picking 003

It’s actually scary how easy it is to not only open tubular locks, but to continue to open them over and over again. To me, these are less secure than household pin and tumbler locks, due to the ease of creating a new key. There are of course ways of impressioning a key blank on a standard pin-tumbler lock, but take much more effort than the tubular lock pick does.

There’s even more to tubular locks that I’ll save for a future discussion, but if you’re interested in jumping ahead, google how to pick a tubular lock with a ballpoint pen.

As always, our goal with providing locking picking information is to continually break down the illusion of security you may depend on to keep your family and personal effects safe. Through gaining more knowledge of this skill-set, you can make more informed decisions when it comes to protecting your valuables.

Remember, locks and security in general is only to buy you time. They’re there to keep honest people honest.

Great video. We have a glass display we lost the key for. Where can I but this tool and is the 7 pin or 8 pin more popular?

How can you tell if your tubular lock is 7 or 8 pin?

I have a harley davidson M/c that has a tubular cam lock for the fork lock, which is jammed in between the locked & unlocked position, does anybody know how to remove the lock? I need to replace it.

I would argue your comment in the video that there aren't Tubular rakes, that the Tubular pick is a raking type pick. You aren't picking individual pins as much as raking several until it opens. Just my two cents

Awesome tutorial, Bryan, thank you! Have been interested in standard picking for awhile and now we have the tubular lick picking explained with video and images! Excellent article!

I know if you look online hard enough you can get the cutters. Most of them are on the pricey side at about $350 but if it hapens a few times the ability to cut your own key could come in handy the, keys run about $.50 per key. I have seen some cutters for the 7 pin locks down around $65 but I have never used them or seen them used personaly. I will put a link in the website box so you can check out the cutters if you want to.

@therock35  If you look closely inside most tubular locks, you can count the pins.
