Our Residential Locksmith Services
Everything you need to keep your home safe and secure.
Home Lockout Service
Locked out of your house or apartment? We respond fast — day or night — and get you back inside without damaging your door or lock. We work on all residential lock types.
Lock Rekeying
Just moved into a new home? Had a break-in? Lost your keys? Rekeying changes the internal pins of your lock so old keys no longer work — it's faster and cheaper than full lock replacement.
Deadbolt Installation
A quality deadbolt is your home's first line of defense. We install Grade 1 and Grade 2 deadbolts from trusted brands like Schlage, Kwikset, and Medeco.
Smart Lock Installation
Upgrade to keyless entry with a smart lock. We install and configure smart locks from leading brands, giving you remote access, activity logs, and temporary codes for guests.
Lock Repair & Replacement
Worn, damaged, or malfunctioning lock? We repair or replace residential locks of all types — knob locks, deadbolts, lever handles, and more.
Master Key Systems
Perfect for landlords and multi-unit property owners. We design and install master key systems that give you access to all units with a single key.
