Our .016" updated lock blocking arrows are designed to restrict unauthorized access to "narrow" keyways.
These tools have a minimal footprint and are easily removed/reused with fitted extractor.
Several reasons you may want to physically deny access to a keyway:
immediate stop gap while you work on a rekeying solution for a home or business
stop people with master keys
legal lockout
safety lockout
Use responsibly. Improper use may result in arrows being difficult or unable to be "recovered".
