The Right Deadbolt Makes All the Difference
A properly installed deadbolt is the single most effective security upgrade you can make to any exterior door. Many homeowners in Westminster, CA rely solely on a knob lock — which can be defeated in seconds. A deadbolt extends a solid bolt 1 inch or more into the door frame, dramatically increasing resistance to kick-ins and forced entry.
Joel Locksmith installs deadbolts correctly: with proper backset alignment, a reinforced 3-inch strike plate, and tight tolerances that prevent rattling or catching. We carry all major brands and grades in our service vans, so most installations are completed in a single visit.
Deadbolt Types We Install
Single Cylinder Deadbolt — Key on the outside, thumb-turn on the inside. The most common choice for standard entry doors. Available in Grades 1, 2, and 3.
Double Cylinder Deadbolt — Key required on both sides. Ideal for doors with glass panels that a burglar could break to reach a thumb-turn. We discuss fire egress considerations before every install.
Grade 1 ANSI Deadbolts — The highest residential security rating. Grade 1 deadbolts resist 250 lb of force and 250,000 open/close cycles. Brands include Schlage B60N, Kwikset 980, and Medeco.
Smart Deadbolts — Keypad entry, Bluetooth, and WiFi-connected deadbolts from Schlage, Yale, and Kwikset. Control your lock from anywhere. See our smart lock installation page for details.
Strike Plate Reinforcement — Every deadbolt installation includes a 3-inch reinforced strike plate with 3-inch screws anchored into the stud frame — not just the door jamb.

Frequently Asked Questions
A single cylinder uses a key outside and a thumb-turn inside — the most common setup. A double cylinder requires a key on both sides, which prevents someone from breaking a nearby window to reach the thumb-turn. However, double cylinders can create a fire egress hazard if not planned for carefully. We discuss this with every customer before installation.
Grade 1 is the highest ANSI/BHMA security rating for residential deadbolts. They withstand 250 lb of direct force and are tested to 250,000 cycles. If you live in an area with higher break-in risk, or simply want the best protection for your front door, we recommend a Grade 1 deadbolt from Schlage, Kwikset, or Medeco.
Standard deadbolt installation ranges from $120–$180. Grade 1 installation is $180–$280. Double cylinder is $150–$220. Smart deadbolt installation is $200–$380. All installations include a reinforced strike plate. We give you a firm quote before we start.
Most standard interior and exterior doors (1-3/8" to 2" thick) accommodate a deadbolt. We assess your door on-site and can bore the proper hole if needed. If the door or frame is weak, we can also reinforce the jamb and frame as part of the installation.
Yes — security best practice calls for both. A knob or lever lock handles everyday convenience; the deadbolt provides the primary security. Many burglars can defeat a knob lock alone in under 10 seconds. We can install both in a single visit and ensure the keys are matched for convenience.
