Usually Deadbolts are associated with safety and security since they provide a reliable way to secure doors. Commonly installed on exterior door and there are 3 types of deadbolts you should know about:
Single cylinder deadbolt
Single cylinder deadbolt is the type that is used the most, it has a keyhole on the outside and a thumbturn feature on the inside.
Double cylinder deadbolt
Double cylinder deadbolt doesn’t posses a thumb turn feature and both sides has a keyhole and require using a key to lock and unlock.
Keyless deadbolt
Keyless deadbolt works as the other two types but as the name suggests it is operated without a key there is no keyhole but only a thumb turn feature from the inside and can only be locked from the inside.
Safety Level
Deadbolts are your home first line defense and protect you from break-ins and when choosing one you should look for the ANSI grading system which rates their security and durability.
Grades range from 1 as the strongest to 3 for basic usage. Although deadbolt locks are not easily compromised we recommend on choosing Grade 1 deadbolts for extra protection and higher resistance to forced entry.
Having a deadbolt on your door can make thieves think twice before messing with your place. They would rather go and look for an easier target.
High security deadbolts can resists break in methods like lock picking and lock bumping and absolutely deter thieves.
