Emergency Locksmith Services
Locked out? Key snapped in the lock? Lock damaged after a break-in? Lock Specialists provide fast emergency response across Simi Valley and surrounding areas. We arrive quickly, work carefully, and restore your access and security without unnecessary damage.
Home Lockouts
Getting locked out is stressful. We get you back inside quickly using non-destructive entry methods that protect your door, frame, and lock.
We unlock:
- House doors
- Apartment doors
- Condo doors
Our technicians are trained in bypass techniques that avoid drilling whenever possible. Most lockouts are resolved in minutes.
Broken Key Extraction
A key snapped inside your lock isn’t just frustrating—it can leave you stranded or your home unsecured. We extract broken keys without damaging the lock mechanism, then test to ensure everything works properly.
We extract broken keys from:
- Door locks
- Deadbolts
- Mailbox locks
If the lock is damaged beyond repair, we can replace it on the spot.
Emergency Lock Repair
When a lock fails unexpectedly—jammed, stuck, or damaged—you need it fixed now. Our mobile technicians carry parts and tools to repair most residential locks on-site.
We repair:
- Jammed locks that won’t turn or release
- Damaged locks after break-in attempts or accidents
- Urgent deadbolt failures
We diagnose the problem, explain your options, and restore function fast.
Burglary Repair & Securing
After a break-in, your priority is securing your home immediately. Lock Specialists responds quickly to replace compromised locks, reinforce damaged frames, and restore your sense of safety.
We provide:
- Post-break-in lock replacement
- Emergency door frame reinforcement
- Temporary board-up service for damaged doors or windows
We can also advise on security upgrades to prevent future incidents.

Standard Residential Locksmith Services
Not every lock problem is an emergency. Lock Specialists handles routine installations, repairs, rekeying, and key duplication with the same professionalism and fair pricing we bring to urgent calls.
Lock Installation
Whether you’re upgrading old hardware, finishing a renovation, or securing a new addition, we install residential locks correctly the first time.
We install:
- New deadbolts
- Doorknobs and lever handles
- Sliding door locks
- Gate locks
- Mailbox locks
We help you choose the right lock for each application and ensure proper alignment for smooth, long-lasting operation.
Lock Repair & Maintenance
Locks wear out over time. Dirt, weather, and repeated use cause sticking, looseness, and misalignment. Regular maintenance extends lock life and prevents lockouts.
We fix and maintain:
- Sticky locks that are hard to turn
- Loose locks with wobbling handles or cylinders
- Misaligned locks that don’t latch properly
- Lock lubrication and preventive maintenance
A small repair now can prevent a costly replacement later.
Lock Rekeying
Rekeying changes the internal pins of your existing locks so old keys no longer work—without replacing the entire lock. It’s faster and more affordable than full replacement.
We provide rekeying for:
- Residential doors (single or whole-home)
- New homeowners who want fresh key control
- Landlords and tenants between leases
- Master key system setup for multi-lock properties
If you’ve moved into a new home, lost a key, or ended a relationship, rekeying restores your security immediately.
Key Duplication & Cutting
Need spare keys for family members, housekeepers, or pet sitters? We duplicate and cut keys on-site with precision equipment.
We duplicate:
- Standard house keys
- Mailbox keys
- Keys cut by code when you’ve lost your only copy
Our key cutting is accurate the first time—no sticky or inconsistent copies.

Security Upgrades & Consulting
Standard locks stop honest people. Determined intruders need stronger deterrents. Lock Specialists installs high-security hardware and provides expert assessments to reduce your home's vulnerability.
High-Security Lock Installation
High-security locks resist common bypass techniques that defeat standard hardware in seconds.
We install:
- Bump-proof locks that resist bump key attacks
- Pick-resistant locks with advanced pin configurations
- Drill-resistant locks with hardened steel components
These locks cost more upfront but dramatically increase the time and noise required to defeat them—often enough to deter burglars entirely.
Door & Window Security Reinforcement
The lock is only as strong as the door and frame holding it. We reinforce weak points that burglars commonly exploit.
We install and reinforce:
- Heavy-duty strike plates with 3-inch screws
- Door jamb reinforcement kits
- Security bars for sliding doors
- Window locks for sliding and sash windows
These upgrades are affordable and significantly increase kick-in resistance.
Home Security Consultation
Not sure where your home is vulnerable? Our technicians assess your property and provide clear, no-pressure recommendations.
We provide:
- Residential security assessments
- Entry point vulnerability analysis
- Product recommendations tailored to your budget and risk level
We tell you what matters most, what can wait, and what’s not worth the money.

Specialty Residential Locksmith Services
Homes have more entry points than front doors. Lock Specialists secures garages, sheds, gates, and safes with the same expertise we bring to your main entrance.
Garage & Outbuilding Security
Garages and sheds are common burglary targets—often less secured than the main home but full of valuable tools and equipment.
We install and repair:
- Garage door locks
- Shed locks
- Gate locks
Proper locks on outbuildings protect your property and can prevent garage-to-home break-ins.
Safe Services
Locked out of your safe? Need to install a new one or change an existing combination? We handle mechanical residential safes with care and precision.
We provide:
- Residential safe unlocking (mechanical safes)
- Safe installation and anchoring
- Safe combination changes
For electronic safe issues, we can recommend qualified specialists.
Access Control (Simple Residential)
Keypad locks and simple electronic access systems offer convenience without traditional keys. We install residential-grade access control for homeowners who want keyless entry.
