Do Alarms Help?
Yes, But…Would you ever buy a car that had an airbag, but no brakes?
A house with a alarm but poor quality locks is identical…– Just as brakes stop you from hitting something and
the airbag is there ‘just in case’ you still do, Good locks prevent the break-in, the alarm is used ‘just in case’ the burglar still gets in.
Nearly half of homes with alarms burglarized didn’t have alarm turned on…
Average Perception of a Lock
All locks are roughly the same – Some offer better strength
– All are generally secure when locked
Expensive locks are generally better looking– Assumed to be more secure
Keys… Keys… Keys…
Hidden for convenience
Given to Neighbors and Friends

What is needed?
Doors are the #1 point of entry:– Keys need protection from duplication.
– Locks provide protection from manipulation
– Locks must be stronger
– System must offer more flexibility where appropriate
We want thieves to make a mess of things before they can gain entry.
Overview of Common Lock Technology
Used on 98% of all residential locks– Inexpensive, often imported
– No extraordinary materials used
– Loose tolerances
– Few code variations (many similar keys)
– Keys can be duplicated by anyone without “proper” authorization.
– Assumed to be secure

How does it work?
Using the Bump Key
Pull key out one position
The key is cut deep enough to allow the bottom pins to remain contained within the plug and not be forced into the shell and block the
shearline.
Using the Bump Key
