For those of you looking for a piece of mind when it comes to home security: the KwikSet's SmartKey deadbolt uses a new un-bumpable
technology called a "side locking bar" instead of a traditional pins and tumblers system...The other notable feature of the KwikSet Smartkey
system besides the stringent security feature is the option to self-program any key for the lock system yourself using a small adaptor which "learns" the new key, rendering the old one obsolete. So you can turn any old key into your new household key and streamline your keychain down to a single key, becoming your own locksmith. Watch how it works here
for more details.
