Philadelphia Professional Locksmiths: Deadbolt Change

Types of Deadbolts

There are three main types of deadbolt locks that make up the majority of deadbolts on properties around Philadelphia. Single-cylinder deadbolts are the most basic, and include a keyhole on the outside and a thumb-turn mechanism on the inside. Double-cylinder deadbolts require a key no matter which side you’re on, which makes them very secure but also a potential barrier if there is a fire or another emergency on the property that requires fast evacuation. For this reason, homeowners are discouraged from installing double-cylinder deadbolts on their main doors. 

The final type of deadbolt is a keyless cylinder deadbolt. These have gained popularity in recent years as people look for ways to enhance and improve their security. Instead of using a key, these locks need a key code or fingerprint scan to disengage. Our locksmiths in Philadelphia can walk you through your options when it comes time to change or upgrade your current deadbolt locks.
