FAQs

Are double cylinder deadbolts safer?

When it comes to single vs. double cylinder deadbolts, double key deadbolts are safer. They require you to unlock the door from inside and outside to gain access, offering an additional level of protection. However, these locks can be difficult in emergencies, and are not allowed by building codes in some areas. Establish a fire/emergency exit plan if you choose a double cylinder deadbolt.

Why would you choose a deadbolt with a key on both sides?

They’re most often used for those with glass panel doors, homes with windows adjacent to doors, and in high-risk areas. Businesses and commercial properties also use these locks for security during non-business hours, or wrought iron gates or doors.

Is a double cylinder deadbolt better than a single?

It depends on your security needs. Some prefer single cylinder deadbolts for their simplicity and convenience. They can be locked/unlocked from the inside using a simple thumb turn or knob for quick exits. Others require a deadbolt with a key on both sides for greater security. Many homeowners opt for both, using double cylinder locks on doors that need extra security.

Can a double key deadbolt be picked?

Since these locks are keyed on both sides, they’re much harder to pick. This deters burglars looking for an easy target.
