When a working key is turned 90 degrees, the change tool can be inserted to move the spring-loaded sidebar housing inwards. A detent holds the sidebar housing in this inward position which keeps the recodeable disc tumblers disconnected in a neutral position. The operating key can then be removed and a new key fully inserted. This key holds each finger tumbler according to the depth of each new key cut. As the new key is then rotated 90 degrees back to a locked position, the sidebar housing is released and each finger tumbler is reunited with the recodeable disc tumblers into the new key cut configuration.
Combination changing is completed in less than a minute. There are thousands of available key combinations and SmartKey locks can be set back to any previous combination as needed, Example: The lock can be changed to a new key to allow workmen to enter a home. Afterwards, the lock can be quickly rekeyed back to the owner's original key cuts which also prevents the workmen from re-entering the home.
This is a revolutionary system. Even though the Weiser SmartKey lock cannot be masterkeyed, it should prove to be a very popular lock for normal residential purposes. Weiser SmartKey Locks are one of the first locksets to meet the challenges of key bumping and vulnerability to picking all included in an economical package.
