What is the difference between a single cylinder and double cylinder deadbolt, and which one do I need?

A single cylinder deadbolt uses a key on the outside and a thumb turn on the inside; a double cylinder requires a key on both sides, which eliminates the glass-break vulnerability but also means you need a key to exit — a critical consideration for emergency egress. Sundial Locksmith can help homeowners in Phoenix weigh the security trade-off against fire safety and local code requirements before making a recommendation. Call (480) 525-7778 to talk through the right choice for your specific doors.
