Lock Replacement in Ventura County

Q: Should I repair or replace my lock?

If the lock is severely worn, has been forced, or is an older model with known security issues, replacement is usually the better investment. If only a single internal part has failed and the lock body is in good shape, repair may be more cost-effective. We assess the lock and give you both options with exact prices.

Q: Can you replace my locks and keep the same key?

Yes. We can rekey new locks to match your existing key, or set up all new locks on one master key. We handle the keying during installation so everything works together when we leave.

Q: How quickly can you replace my locks?

We carry common locks in our service vehicle. Most single lock replacements take 30-60 minutes. Multi-lock replacements are typically completed in a single visit.

Q: What brands do you carry in the van?

We stock Schlage, Kwikset, Yale, and select Baldwin and Medeco hardware. For specialty or high-security locks, we may need to source the hardware and schedule a return visit, usually within 1-2 business days.

Q: Do I need to buy the lock, or do you supply it?

We supply and install. The hardware cost is included in our quote. You are also welcome to purchase your own lock and we will install it, in that case, you pay labor only.

Q: Is it worth upgrading from Grade 3 to Grade 2?

Almost always, yes. The price difference is typically $20-40 per lock, but the security upgrade is significant. Grade 2 locks last longer, resist more force, and have better internal components. We recommend Grade 2 as the minimum for any exterior door.

Q: What about smart locks, are they secure?

Modern smart locks from reputable brands (Schlage, Yale, August) are as physically secure as traditional deadbolts. Many are ANSI Grade 1 rated. The convenience of keyless entry, remote access, and guest codes makes them a popular upgrade. We install and configure them as part of our replacement service.

Q: Can you replace locks on a commercial building?

Yes. We install Grade 1 and Grade 2 commercial hardware, handle master key coordination, and ensure ADA and fire code compliance. See the Commercial Lock Replacement section above for details.

Q: How long do replacement locks last?

Grade 2 locks are rated for 400,000 cycles and typically last 15-25 years with basic maintenance. Grade 1 locks are rated for 800,000 cycles. Coastal environments reduce these numbers, which is why we recommend corrosion-resistant materials for homes near the water.

Q: What if my door frame is damaged?

We assess the frame during every replacement. Minor damage can be repaired with a door reinforcement kit. If the frame is severely rotted or compromised, we let you know before proceeding. Installing a new lock on a bad frame is a waste of money, and we will not do it without addressing the frame first.

Worn-out deadbolts, builder-grade hardware that should have been replaced years ago, salt-corroded coastal locks that barely turn, we remove the old and install the new, on-site, same day. We stock Schlage, Kwikset, Yale, Baldwin, Medeco, and Mul-T-Lock in the van so most replacements happen in a single visit with no waiting on parts.

Decision Guide

Replace, Repair, or Rekey. Which One Do You Need?

These three services overlap, and picking the wrong one wastes money or leaves you less secure than you think. Here is how to tell which one you actually need.

You need replacement when:

The lock body is cracked, bent, or physically damaged
The lock has been forced or kicked during a break-in
Internal corrosion has reached the mechanism (not just the surface)
The lock is a discontinued model with no available parts
You want to upgrade from builder-grade to a higher security grade
The lock is more than 20 years old and shows signs of wear
You are changing from a traditional lock to a smart lock

Repair might be enough when:

The key is stiff but the lock body is intact
A single internal part (spring, tailpiece, cam) has failed
The problem is alignment, not the lock itself

Rekeying is the right call when:

You just moved in and want to make sure old keys do not work
You lost a key and want to invalidate it
You want all your locks on one key for convenience

The most common mistake we see is homeowners rekeying a lock that should have been replaced. If the hardware is worn, corroded, or low-grade, rekeying just gives you a new key for a bad lock. We assess the hardware first and give you an honest recommendation.

Options

Types of Lock Replacement

Deadbolt Replacement

The most common replacement we do. Old deadbolts with worn cylinders, bent bolts, or corroded internals get swapped for a new unit matched to your existing door prep. We install single-cylinder, double-cylinder, and keyless deadbolts from every major brand. Every replacement includes proper strike plate installation with 3-inch screws into the wall stud.
Full Lockset Replacement

Replacing the complete knob-and-deadbolt set on an entry door. This is the right call when both the knob and the deadbolt are worn, when you want matching finishes on a door, or when upgrading from builder-grade hardware. We carry matched sets from Schlage, Kwikset, and Yale in the van. We can key the knob and deadbolt alike so one key opens both.
Mortise Lock Replacement

Mortise locks are found in older homes and commercial buildings. The lock body sits inside a rectangular pocket (mortise) cut into the door edge. Replacing a mortise lock requires matching the exact body dimensions, backset, and face plate layout of the original. We measure on-site and carry common mortise bodies. If your home has vintage hardware with non-standard dimensions, we source compatible replacements.
High-Security Upgrade

Replacing standard locks with high-security hardware from Medeco, Mul-T-Lock, or Abloy. High-security locks feature patented keyways (keys cannot be duplicated without authorization), pick-resistant pin mechanisms, drill-resistant housings, and bump-proof technology. Ideal for front doors, home offices, and any door protecting valuables. We register your keyway and provide an authorization card for future key copies.
Smart Lock Upgrade

Replacing a traditional deadbolt with a modern keyless smart lock. We remove the old hardware, install the new lock, set up the app, program user codes, configure smart home integration, and test the backup key cylinder. We install smart locks from Schlage, Yale, August, Kwikset, and Ultraloq. The physical installation is straightforward, it is the digital setup that most people struggle with, and that is where we save you time.
Commercial Lock Replacement

Replacing worn or damaged commercial-grade locks on office doors, storefronts, and industrial facilities. We install Grade 1 and Grade 2 cylindrical locks, mortise locks, and electrified locks from Schlage, BEST, Corbin Russwin, and Sargent. Commercial replacement often involves master key coordination, ADA compliance, and fire code considerations that residential work does not. We handle all of it.

Lock Grades

Lock Grades and Builder-Grade Problems

Understanding ANSI/BHMA Lock Grades

Every lock sold in the US is rated by ANSI/BHMA on a scale from Grade 3 (basic) to Grade 1 (highest security). Understanding the grades helps you make a smarter replacement decision.

Grade 3. Basic Residential

Rated for 200,000 cycles. This is what builders install to meet code minimums. Cheap zinc alloy internals, short bolt throw, lightweight strike plates with short screws. Grade 3 locks are acceptable for interior doors and closets but are not recommended as your primary exterior security.

Grade 2. Standard Residential / Light Commercial

Rated for 400,000 cycles. Significantly stronger internals, better bolt throw, and higher force resistance. Grade 2 is the sweet spot for most homeowners, solid security at a reasonable price. This is what we recommend for most exterior door replacements.

Grade 1. Commercial / Maximum Security

Rated for 800,000 cycles. The highest rating. Heaviest materials, longest bolt throw, maximum force resistance. Standard in commercial settings but also makes sense for homeowners who want the best. Costs more upfront but lasts significantly longer.

Our recommendation: replace Grade 3 exterior locks with Grade 2 at minimum. If you are replacing locks anyway, the price difference between Grade 3 and Grade 2 is usually $20-40 per lock, a small investment for a meaningful security upgrade.

Why Builder-Grade Hardware Is a Problem

Zinc alloy internals wear out in 5-10 years, compared to 15-25 years for brass-core locks
Short strike plate screws (3/4 inch) anchor only in the door frame trim, not the structural stud behind it
Narrow bolt throw means the deadbolt does not extend far enough into the frame to resist kicking
Cheap keyway cylinders are easier to pick, bump, and duplicate without authorization
Surface finishes degrade faster, especially in coastal environments, accelerating internal corrosion

If your home was built in the last 20 years and the locks have never been replaced, you almost certainly have Grade 3 hardware. We see it on 8 out of 10 service calls. Replacing it is one of the single most effective security upgrades you can make for your home.

Coastal Living

Coastal Hardware Guide

If you live within a few miles of the Ventura County coastline, your lock hardware is fighting salt air every single day. Salt-laden moisture gets into the pin stack, the bolt mechanism, and every moving part. Over time, it causes pitting, seizing, and outright failure.

What Happens to Your Locks

Deadbolt bolts pit and drag, eventually refusing to extend or retract
Exterior finishes corrode, flake, and turn green (especially brass-plated zinc)
Cylinders freeze internally as salt crystite builds between pins
Screws rust into the frame, making removal difficult and damaging the wood

How Fast It Happens

Within 1/2 mile of the water

Visible corrosion in 2-3 years. Functional problems in 4-6 years.

1/2 mile to 2 miles

Visible corrosion in 4-5 years. Functional problems in 7-10 years.

2 to 5 miles

Slower degradation, but still faster than inland. Plan for replacement every 10-15 years.

What We Recommend

Choose solid brass or 316 marine-grade stainless steel for exterior locks whenever possible
Avoid brass-plated zinc alloy, the plating chips and the zinc underneath corrodes rapidly
Apply dry graphite lubricant to cylinders every 6 months (never WD-40 or oil-based lubricants)
Replace exterior hardware proactively every 7-10 years in coastal zones, even if it still works
Baldwin Living Finish hardware is designed to develop a natural patina that actually protects the base metal, worth considering for coastal homes where appearance matters

What Pushes the Price Up or Down

Lock grade: Grade 1 costs more than Grade 2, which costs more than Grade 3
Door prep: If the new lock requires a different bore size or additional holes, prep work adds cost
Keying: Matching a new lock to existing keys (rekeying) adds a small charge per lock
Number of locks: Multi-lock replacements get a per-lock discount
Hardware source: If you supply the lock, you pay labor only. If we supply it, the lock cost is included in the quote
Complexity: Commercial doors, fire-rated doors, and non-standard frames take more time and may require specialty hardware

A Note on Locksmith Pricing

If you see a locksmith ad quoting $15 or $19 for lock replacement, that is a bait price. The real cost shows up after they arrive, inflated labor charges, "emergency" fees, and pressure to pay cash. A legitimate licensed locksmith gives you the full price before starting, puts it in writing, and charges what was quoted. We do exactly that on every job.

Pro Tips

Pro Tips From the Field

"It still turns, so it's fine"

A lock that requires extra force, jiggling, or lifting the handle to operate is telling you it is wearing out. Every forced turn accelerates the wear. What could be a clean replacement today becomes an emergency replacement (with possible door damage) six months from now. Replace it while you can plan the job, not when it fails at midnight.

Your new lock is only as strong as the frame

A $300 deadbolt installed in a rotted frame with 3/4-inch screws is not secure. Every lock we install gets 3-inch screws in the strike plate that anchor into the wall stud behind the trim. This single detail is the difference between a door that resists a kick and one that does not. If the frame is soft or damaged, we address that before installing the new lock.

Plan your keying before we start

If you are replacing multiple locks, decide up front whether you want them all on the same key (keyed alike), on separate keys, or on a master key system. Changing the keying plan after installation means pulling cylinders and repinning them, which adds time and cost. We will ask you about keying before we start and set everything up in one pass.

Skip the DIY rekey kits

Kwikset SmartKey and Schlage SecureKey allow homeowner rekeying. In theory. In practice, we get multiple calls per month from people who have jammed the mechanism mid-rekey. Once jammed, the lock will not open with any key. If you are replacing locks anyway, let us handle the keying during installation and save yourself the headache.

Coastal homeowners: lubricate right

Use dry graphite powder or a PTFE-based lock lubricant. Never WD-40, which is a solvent that attracts dust and accelerates corrosion in salt air environments. A quick squirt of graphite into the keyway twice a year keeps your new lock operating smoothly for the life of the hardware.

Check your locks after earthquake activity

Even a moderate earthquake can shift door frames enough to misalign locks. After any noticeable seismic event, test every exterior lock by fully extending and retracting the deadbolt. If it binds, drags, or does not fully extend, call us for an alignment check before the problem gets worse.

Commercial

Commercial Lock Replacement

Commercial lock replacement is not just about swapping hardware. Business doors are subject to building codes, ADA requirements, fire safety regulations, and insurance standards that residential doors are not. Getting any of these wrong can result in fines, failed inspections, or liability exposure.

Common Reasons for Commercial Lock Replacement

Employee Turnover

When employees leave, especially on bad terms, replacing or rekeying locks is a security priority. For businesses with frequent turnover, we recommend keyless entry systems that let you revoke access by deleting a code rather than changing hardware.

Break-In Damage

After a commercial break-in, locks, frames, and door hardware often need replacement, not just repair. We document all damage for your insurance claim and install upgraded hardware to reduce the chance of a repeat event.

ADA Compliance

California Title 24 requires that door hardware on accessible routes be operable with one hand, without tight grasping or twisting. Round knobs do not meet this standard, lever handles do. If your business has round knob locksets on accessible routes, they need to be replaced with ADA-compliant lever hardware. We identify non-compliant hardware and replace it with code-compliant alternatives.

Fire Code Requirements

Exit doors in commercial buildings require panic hardware (crash bars) that allows immediate egress without keys, special knowledge, or effort. Panic bars must be installed at the correct height and must release with no more than 15 pounds of force. Doors on fire-rated openings require fire-rated hardware and self-closing devices. Mag-lock systems on fire exits must release automatically when the fire alarm activates or when power is lost (fail-safe). We install and verify all of this as part of commercial lock replacement.

Why Code Knowledge Matters

Code knowledge is what separates a locksmith from a handyman with a drill. We know Title 24, we know fire code, and we know what inspectors look for. When we replace commercial locks, the hardware passes inspection because we install it to code the first time.

Reviews

What Our Customers Say

★★★★★

Had all four exterior doors done in one visit

"Tim replaced the deadbolts and entry knobs on all four exterior doors. Keyed them all alike so we only need one key. The old locks were original to the house (25+ years) and barely functioned. Night and day difference. He also used 3-inch screws on every strike plate, which the original installer did not do. Solid work, fair price, done in one afternoon."

Ashley M., Thousand Oaks

★★★★★

Finally replaced our corroded coastal locks

"We live two blocks from the beach and our front door lock was so corroded it took two hands to turn the key. Tim replaced both the deadbolt and knob with stainless steel hardware rated for coastal environments. He also checked every other exterior lock and gave us a maintenance plan for the salt air. Should have called him a year ago."

Derek M., Oxnard

★★★★★

Upgraded from builder-grade to Grade 2 on every door

"Our house is 12 years old and every lock was the cheapest builder-grade hardware. Tim replaced all five exterior locks with Schlage Grade 2 deadbolts and entry sets. He matched the finish across all doors and keyed everything to one key. The locks feel completely different, solid, smooth, and secure. Worth every penny."

Luis H., Ventura
