A tubular lock pick is a specialized lockpicking tool used for opening a tubular pin tumbler lock. Tubular lock picks are all very similar in design and come in sizes to fit all major tubular locks, including 6, 7, and 8-pin locks.
The tool is simply inserted into the lock and turned clockwise with medium tension. As the tool is pushed into the lock, each of the picks is slowly forced down until they stop, thus binding the driver pins behind the shear line of the lock. When the final pick is pushed down, the shear plane is clear and the lock opens. This can usually be accomplished in a matter of seconds.
Most tubular lock picks come with a “decoder” which lets the locksmith know at what depths the pins broke the shear plane. By using the decoding key after the lock has been picked, the locksmith can cut a tubular key to the correct pin depths and thus avoid having to replace the lock.
In 2004 it was widely publicized that the barrel of a cheap ballpoint pen would act as an effective lock pick for many brands of tubular lock.

A tubular pin tumbler lock, also known as Ace lock or “axial pin tumbler lock” or “radial lock”, is a variety of pin tumbler lock in which 6-8 pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape.
J.A. Blake is credited with patenting the first tubular lock in 1833. Walter R. Schlage continued the development of the tubular lock. He was awarded 11 patents, and his improvements made the tubular lock what it is today.
Tubular locks are commonly seen on bicycle locks, computer locks, and a variety of coin-operated devices such as vending machines and coin-operated washing machines.
Security
Tubular pin tumbler locks are generally considered to be safer and more resistant to picking than standard locks, though there are several ways to open them without a key. Even though the pins are exposed, making them superficially easier to pick, they are designed such that after all pins are manipulated to their shear line, once the plug is rotated 1/6 to 1/8 around, the pins will fall into the next pin’s hole, requiring re-picking to continue. As such, picking the lock without using a device to hold its pins in place once they reach their shear line requires over a dozen complete picks to unlock and relock.
Such locks can be picked by a special tubular lock pick with a minimum of effort in very little time; it is also possible to defeat them by drilling with a special “hole saw” drill bit. Standard tubular lock drill bit sizes are .375″ (9.53 mm) diameter and .394″ (10 mm) diameter.[1] To prevent drilling, many tubular locks have a middle pin made of hardened steel, or contain a ball bearing in the middle pin.
In 2004, videos circulating on the Internet demonstrated that some tubular pin tumbler locks could be easily opened with the shaft of an inexpensive ballpoint pen (e.g. BIC brand) of matching diameter. Trade website BikeBiz.com revealed that the weaknesses of the tubular pin tumbler mechanism had first been described in 1992 by UK journalist John Stuart Clark (see Kryptonite lock).
