Deadbolts are the #1 recommended security lock for every exterior door. We install single-cylinder, double-cylinder, smart, and high-security deadbolts. Call (210) 348-3677.

What We Do

A deadbolt provides significantly more security than a spring-latch knob lock because its bolt extends deep into the door frame and cannot be forced open with a credit card. S.A. Locksmith & Security installs and services single-cylinder deadbolts (keyed outside, thumb-turn inside), double-cylinder deadbolts (keyed both sides), jimmy-proof deadbolts (vertical bolt), electronic/keypad deadbolts, smart deadbolts (Wi-Fi/Bluetooth), and high-security deadbolts (Medeco, Mul-T-Lock). We recommend ANSI Grade 1 or Grade 2 deadbolts with a minimum 1-inch throw bolt and reinforced strike plate for maximum kick-in resistance.

Frequently Asked Questions

How much does deadbolt installation cost?

Deadbolt installation costs $75-$200 including hardware and labor. High-security deadbolts cost $150-$400. Call (210) 348-3677.

What is the best deadbolt for a front door?

We recommend an ANSI Grade 1 or Grade 2 deadbolt from Schlage or Medeco with a reinforced strike plate and 3-inch screws.

What is the difference between Grade 1 and Grade 2 deadbolts?

Grade 1 deadbolts withstand 10+ strikes at 75 lbs of force and are the highest residential rating. Grade 2 handles 5 strikes and is suitable for most homes.

Can you add a deadbolt to a door that doesn't have one?

Yes. We drill and bore the door and frame to install a new deadbolt — typically takes 30-45 minutes.

Are smart deadbolts secure?

Yes. Quality smart deadbolts from Schlage and Yale meet ANSI Grade 2 standards and add the convenience of keyless entry, auto-lock, and remote access.
