Locking your door doesn’t always prevent theft. It’s possible that a determined burglar will simply break the glass and unlock the door from the inside. To increase your home security, consider installing double cylinder deadbolts.
Double cylinder deadbolts require a key on both sides of the lock to get in and out of the house. Meaning even if a burglar does break a glass pane, there will be no inside knob for them to turn. Just remember not to leave the second key sitting in the lock, especially when you're not home. Instead, keep a key near the front door inside a decorative wall basket or desk, and out of the sight and arm’s reach of potential burglars.
While double cylinder deadbolts are the most secure type of deadbolt around and great for added security, some people prefer not to use them due to the safety concerns. In the event of a fire, a misplaced key can prevent residents from escaping their house quickly and lead to fatal accidents. For this reason, some fire safety and building codes forbid the installation of locks that require keys to open the door from the inside.
Remember, check your area’s fire code first and consult with a local contractor or locksmith before installing a double cylinder deadbolt.
