If you’ve ever needed to make sure that no one could get into a building until you can get the locks changed it can be a little hard to accomplish. As soon as that lock is changed you’re fine, but until then the residence is left unprotected. That’s bad news for landlords trying to boot out freeloading tennats. If you know you can’t get in to get a new lock immediately you could keep a stash of these Lock-Kills from DG3 Locksmithing. They’ll make sure that no one gets through that deadbolt.
After someone has been evicted the property manager could then put in this key into any Kwikset lock and the end of the key will break off inside once you twist the key. That piece stays inside making it impossible to open the deadbolt. These are strictly meant for the use of locksmiths and property managers, but I’m sure that at least a few people will use them for mischief instead of practical reasons. You can purchase one of these patent pending keys for $19.95.
