A quality deadbolt is one of the most effective and affordable ways to improve your home’s security. Armour Locksmith installs single-cylinder, double-cylinder, and smart deadbolts for homeowners throughout St. Louis, MO. Whether you’re upgrading old hardware, adding a lock to a new door, or converting to a smart lock system, we’ve got you covered.
Why Deadbolts Matter for Home Security in St. Louis
Standard doorknob locks can be forced open with surprising ease. A properly installed deadbolt adds a second layer of protection that is significantly harder to defeat. Security experts consistently recommend deadbolts as a baseline requirement for any exterior door. Upgrading to a high-quality deadbolt is one of the simplest, most impactful steps St. Louis homeowners can take to protect their families and property.

Types of Deadbolts We Install
Single-Cylinder Deadbolts
The most common deadbolt type — keyed from the outside, thumb-turn from the inside. Ideal for most exterior doors in St. Louis homes. Quick to operate from inside in an emergency, and highly effective against forced entry when properly installed with a reinforced strike plate.
Double-Cylinder Deadbolts
Keyed on both sides, double-cylinder deadbolts are often chosen for doors with glass panels, where an intruder could otherwise break the glass and operate a thumb-turn from inside. Note that building codes in some areas restrict these on primary exit doors — Armour Locksmith will advise you on the right choice for your specific door and situation in St. Louis, MO.
Smart & Keypad Deadbolts
Smart deadbolts let you lock and unlock your door with a keypad code, smartphone app, or voice assistant. They’re ideal for St. Louis homeowners who want keyless convenience without sacrificing security. Armour Locksmith installs and programs smart deadbolts from leading brands, ensuring your device works reliably from day one. You may also want to consider our lock rekeying service to update your existing hardware at the same time.
