How to Reinforce Deadbolts

A reinforced deadbolt adds security to the entry points of your home, making it more difficult for a burglar to breach the lock. A deadbolt is more secure than a basic lock, but without the proper reinforcement the door can be kicked in. A grading system is used to indicate the durability of a deadbolt. Other factors include the strike plate and the screws used to hold the strike plate in place. Make upgrades to your existing deadbolt or replace it completely for security.
