A knob lock alone is not security. We install quality deadbolts, Schlage, Kwikset, and high-security options, with reinforced strike plates that make your door seriously hard to force.
Costa Mesa Locksmith
Here is an uncomfortable fact: the lock in your door handle can be defeated in seconds. A deadbolt is different. A one-inch steel bolt thrown into a reinforced frame is what actually stops a forced entry, and it is the single best security upgrade most Costa Mesa homes can make for the money.
Our deadbolt installation service handles everything: choosing the right bolt for your door, drilling clean, precise holes (including on doors that never had a deadbolt), fitting the lock, and reinforcing the strike plate with 3-inch screws that bite into the wall stud, not just the trim. That last step is the one most installers skip, and it matters most.
Costa Mesa Locksmith is run by the licensed team behind Golden Locks Inc. (CA License LCO4446). We install single-cylinder, double-cylinder, and keypad deadbolts from Schlage, Kwikset, and Yale, plus high-security Medeco options for homes that want key control too.
Services
Every install includes the lock, a reinforced strike, long screws, and a full alignment check of your door.
More than the bolt
Here is what most people never hear: a strong deadbolt in a weak frame still fails. The strike plate, the little metal box your bolt slides into, is often held by short screws that bite into soft trim. We anchor ours with long screws that reach the wall stud, and that one detail multiplies the strength of the whole door.
We fit Grade 2 deadbolts from Schlage and Kwikset, single or double cylinder, matched to your existing keys when possible. Every install ends with you throwing the bolt yourself: smooth, solid, and seated all the way.

One number covers hardware, labor, reinforced strike, and keys. Multiple doors in one visit get a per-door discount, ask when you call. Fire-code note: we will never install a double-cylinder bolt where it would trap your family; safety first, always.
How it works
Thickness, material, existing holes, and frame condition decide the right bolt. You get options with honest prices.
Pro jigs keep holes dead-true. The bolt, cylinder, and trim are fitted snug with no sloppy gaps.
We swap the flimsy strike screws for 3-inch screws anchored in the stud. This is where forced-entry resistance really comes from.
The bolt must glide with one finger. We adjust until it does, then hand you your keys.
Local & proud
Costa Mesa housing runs from 1950s ranch homes in Mesa Verde and College Park, many with their original doors, to new-build condos near South Coast Plaza that ship with the cheapest locks the builder could buy. Both ends of that spectrum need real deadbolts. Older doors often need a fresh, precise hole and some frame care; newer doors need hardware worthy of the home.
We install across 92626, 92627, and 92628, including Back Bay-adjacent homes where the salt air argues for stainless or coated hardware. If your door has glass beside it, common in Eastside entries, ask us about the double-cylinder rules and safer alternatives like keypad bolts.
Good to know
Ask a locksmith what stops a kicked door and you will not hear 'the lock brand.' You will hear 'the strike.' Most doors ship with a thin strike plate held by half-inch screws into soft trim. One kick and the frame splits. Our installs replace that with a heavy strike box and 3-inch screws that reach the wall stud, turning the weakest point of your door into one of the strongest.
It adds minutes to the job and almost nothing to the bill, and it is included in every deadbolt we install in Costa Mesa. If a previous installer skipped it on your existing locks, we can retrofit reinforced strikes on their own, a small visit that buys real peace of mind.

Good questions
With the lock supplied by us, most standard deadbolts total $110 to $165 installed. Labor alone is $55 to $85 when the hole exists, $85 to $130 for a fresh drill. Keypad and high-security models cost more, quoted up front.
Yes, this is a daily job for us. We use professional drilling jigs for a clean, exact fit on wood, steel, and fiberglass doors, and we reinforce the frame at the same time.
For most homes, a Grade 2 Schlage or Kwikset offers the best strength-per-dollar. For key control and maximum resistance, Medeco is the step up. We install all three and will explain the trade-offs honestly.
It can be risky: in a fire, you need a key to exit. California code restricts them in some sleeping-area doors. We will recommend single-cylinder or keypad options where glass is not a threat, and discuss the rules openly before installing anything.
About 30 to 45 minutes per door with an existing hole, a bit longer for fresh installs. Multiple doors in one visit run faster per door.
Yes. We carry the right bits and backing hardware for steel and fiberglass doors, and we seal the fit against coastal moisture when we are done.
