TECHNICAL INFORMATION AND DEFINITIONS
Most of the work I do is "re-keying" locks, that is, simply setting it
to operate on a different key. This locks out existing keys and
new keys are then used. There's usually no reason to replace
good hardware, which is much more expensive than re-keying.
Many different brands and types of locks can be keyed-alike
including padlocks and cabinet locks. Masterkey systems can
also be created for individual situations.
"Re-Keying" means to change the
pins (tumblers) in a lock so that it
operates on a different key -
"combination".
Keyed Alike (KA)is two or more
locks operate on the same key.
Master-Keying (MK) is the condition
in which two or more different key
combinations operate a lock.
TUBULAR ENTRY LOCK:
Kwikset 400 Series, "Polo" style.
Basic doorknob or lever-set.
Mostly low to medium security,
good for locking yourself out!
TUBULAR DEADBOLT:
Deadbolts are available from
many manufacturers in a variety
of functions and finishes. Most
of them are "single cylinder" or
"double cylinder", doubles use a
key on both sides.
MORTISE CYLINDER:
One of the only things that's "standard" in
this industry. Available from nearly all
lock manufacturers for a vast amount of
lock configurations. Different lengths and
cams are used depending upon
application.
SCHLAGE 'A' SERIES CYLINDER:
Used in the very popular Schlage locks, this versatile little
cylinder is the new standard. It's used anywhere it'll fit
including cabinet locks, padlocks and bicycle cables. Also
available from nearly all manufacturers in an endless
selection of keyways and lock cylinder mechanisms.
PROFILE CYLINDER:
Standard cylinder throughout much of the world. Increasingly
popular here as the decorator hardware movement seeks
ever more obscure hardware. This is a regular size one,
there are also smaller ones and other styles like "oval
cylinders"
CAM LOCK:
Small lock used for cabinets, tool
boxes, deposit safes and panels.
Low, Medium and High security
versions available.
POP-OUT VENDING MACHINE LOCK:
Used on vending machines, different
styles and levels of security available.
INTERCHANGEABLE CORE (IC):
Original Best style core also known as Small Format
Interchangeable Core (SFIC). Made by many companies, it's
the single most versatile lock cylinder in the world!. There
are more kinds of locks (housings) for this cylinder than any
other including the usual door locks and padlocks, there are
many specialty locks available. Key systems written for any
application, large, small, or just one.
REMOVABLE CORE (RC):
Similar to SFIC, Large Format Interchangeable Cores
(LFIC), are limited to a very small number of housings,
usually made by the manufacturer of core. The
interchangeable part is much more limited than with SFIC.
RIM-CYLINDER NIGHT-LATCH:
Inside surface mounted, used to be an upgrade to the old
skeleton-key locks before tubular deadbolts became more
common.
"Jimmy-proof" vertical deadbolt:
Interlocking design. Also surface mounted inside and rim-cylinder outside. Great for many
applications including gates and sliding doors but get a good one not a junky one like the one
in the picture. The cheap ones are hardly kick resistant at all. Yale has one made in England
that's good. Medeco markets the Segal brand jimmy-proof. They also have available a large
plate to protect the outside cylinder.

MORTISE LOCK
mortise cylinders for more security. In other parts of the word using different PROFILE cylinders.
They can be very small or large with multi-point locking arrangements. Mortise locks are limited
only by the imagination and budget. Many mortise locks are used with decorative trim on the
entrances of premium homes. The "Stamm" homes built here in Santa Fe in the 50'shave a
mortise lock on the front door and most of them still work! If they are worn out, there are several
options depending on your budget. Mortise locks are mainly used in commercial buildings of all
kinds with factory trim. They are more expensive than the tubular locks, MSRP for a plain moritse
lock is around $900. A decorative one is roughly $1500, depending on trim.
Note: People in Santa Fe love things like this but they are not practical from a security standpoint.
Also, Re-keying and key cutting isn't nearly as efficient or effective as with pin-tumbler locks. I
don't cut these keys or work with these locks because the labor and turn-around time is too much
for todays market. It's romantic but not a money maker.
PADLOCKS
LUBRICANTS:
The lock cylinder, where the key goes, contains very small and precise parts and if just one of them
sticks, the lock wont open. Graphite has been the traditional lubricant of choice and it's still excellent. It's
just messy and a can of Lock-Saver is much better. It will even flush out dirt and other lubricants. Avoid
spraying things like WD40 into lock cylinders if possible.
Latches, bolts and hinges are not quite as touchy and nearly any general lubricant will do . I prefer
LokShot, it's a really great all-purpose lubricant.
Other Mortise Locks...coming soon.
Left, a Peanut Cylinder, there are still a few doors
in town that use these.
Center, standard size cylinders.
Right, a Jumbo cylinder, not too common around
here. It's also a "Master-Ring" cylinder which
means two shear-lines inside for large systems.
With one or more pins blocking it,
the old key will break if forced.
For great mortise locks and great company
support, try Accurate Lock & Hardware. They have
a very interesting product line including mortise
locks for nearly any application. I have seen them
on custom homes from 1 1/2" to over 5" backsets.
