Thank you shoff. I did not see that one.
Say, do you know of a Shoff who joined the Marine Corps in 1960. A Shoff was in my series and qualified with a score of 236 Expert rating for Series High Shooter Award.0 -

This method has been around for years, known by locksmiths as "rapping", but for some reason has recently gotten a huge amount of press.
It does work pretty well, but takes a little practice to get consistent results.0 -

Most people don't understand how the typical pin and tumbler lock works.
There's a cylinder inside of your lock, which is attached to your locking mechanism (by turning it you "open" the lock). And there's a very small "cut" in it called a shear line.
There are several pins pushed down into a small crevice. They are held in place by spring pressure. These pins are broken into 2 parts by a very small fracture (kind of like a broken firing pin come to think of it). When the fracture points of all pins line up with the shear line, the cylinder can be turned.
What allows keys to work is that the fracture points in the pins are at different locations. So on one lock, the first pin might have a fracture near the bottom, and on another lock, it may be near the top of the pin. Or it could be in the middle, or one milimeter below or above. Since most P&T locks have at least 5 pins, and the fracture point adjustments can be very slightly different, this allows for a large number of different key "combinations" That's why when you look at 2 different keys of the same size, the "teeth" or little triangles are of different heights and at different locations.
A lock is picked by applying pressure to the tumbler in the direction the key would open it. This forces the shear line tightly against the pins. If you push the pins up to the correct height individually, the top part of the pin (above the fracture) will catch on the shear line if the tumbler is being pushed hard enough against the pins. But this takes a considerable degree of skill. The adjustments you make to the pins are incredibly slight, and you have to listen very carefully to know when a pin has caught the sheer line. Furthermore, 90 to 95% of criminals have no knowledge of lock picking... Or have no desire to attempt it because they are too stupid. Else a wise homes would constantly be broken into, and cars incessantly stolen.
Medeco locks do not use the P&T system and CANNOT be picked... It is a physical impossibility. They can be BROKEN (just like an object on earth) or "rekeyed", but not picked. There are a few different kinds of locks... but P&T is the most commmon.0 -
Medeco still uses a pin system, the difference is in the angle bitting of the keys. The pins have angled tips which have to be turned the proper direction (left,center,right) in order for the sidebolt to drop into place on the cylinder. Medeco locks CAN be picked, but it involves a lot more luck than skill.
Also, to add to your post, locks that are master keyed, sub-master keyed, grand-master keyed etc. are even more prone to picking because of the increased number of shear lines available.0 -
Yeah bumpkeys are so bad..
But if it's to complicated - just buy a lifetime warrantied Snap-Gun lockpick gun and practise away.

And yes - they sell to anyone.
If it can't be snapped open - you might have success picking it.
At least with lockbumping, you'd hear the smack.
As for safety - buy a chain or a simple sound-device.
It might not do much in the long run, but it'll still buy you a few seconds of precious time.0 -

A sound device isn't going to do anything if you're not home... they are just going to steal everything. Unless it is loud enough to hurt their ears - in which case, they might take off.

If I owned a high security lock company I'd be buying full page ads explaining how easy this is to do.

Unless you're in business as a locksmith or otherwise able to articulate a legit reason, in some states possession of a tool designed specifically for defeating locks can get you in a bind for "possession of a criminal instrument". Same with bump-keys.
Also, a single keyed deadbolt gives much more protection than a POS security chain.0
