Product Features
Key Lock At Both Sides
Pro:
Required key to be used on both sides of the door, which added security measure because no one is able to leave through the door without a key once the deadbolt is locked.
Con:
The same features that make double-keyed deadbolts attractive to people seeking added security can make them dangerous in emergencies.
– Must locate key when evacuating in fires and other emergencies.
– Risk of being trapped in your home if the key is lost or the lock is jams.
– Easier to get locked out of your home.
Application:
This is a good option for doors with glass or windows since an intruder can’t break into the door even if the glass/window is broken.
