There are websites and videos/DVDs all about the level of (in)security that
common and sophisticated locks provide.

MythBusters did a show where they defeated some very high-tech locks,
including fingerprint verification locks.

A secondary consideration of security would be the material the lock is
mounted to. Soft pine or MDF door frames have no strength, and a good prybar
can easily overcome the strength of those soft materials very easily with
little noise.

Many of the metalworking types here in RCM have the imagination, skill and
equipment to fabricate long, heavy duty reinforcement plates of heavy gage
steel to reinforce their doors and locking mechanisms.

Many cheaply made door handsets with the lock integrated into the doorknob
are easily defeated with force, a strong grip or tool that can be used to
apply considerable torque can easily provide enough force to break the
internal parts and provide a criminal with a quiet, easy entry.

There are often easier ways to enter a secure area other than a secure door,
in which the secure door may just provide an easy exit from the inside.

The usage of the term security is a fallicy in most cases, in any area of
our lives.. whether it's borders or neighborhoods, privacy, communication of
all types, or places we live in or go to, even food, water or various
commercial products (tylenol lacing 1982 and 1986).

Lock picking is a traditional interest and activity for MIT
undergrads. Jeff Wisnea could elucidate if he might care to.
