Lock Repairs

Efficient Repairs Before Replacements - Saving You Time and Money

We begin every residential service with a commitment to repair first, replace only when necessary. Most locks - especially mid to high-grade hardware - can be restored with skilled adjustments or internal part replacement. This preserves your door’s look and function while saving on cost.

We troubleshoot:

• Misaligned latches
• Sticking or jamming mechanisms
• Broken internal springs or tailpieces
• Loose or spinning cylinders

Our fully stocked mobile units allow us to repair or replace most locks during the first visit. We’ll walk you through the options and never upsell what you don’t need.

Old & Mortise Lock Restoration

Preserving Boston’s Character, One Door at a Time

Older homes often feature original mortise locks - strong, elegant mechanisms that deserve expert attention. These locks are common in historic properties, brownstones, and luxury buildings across the region.

Instead of replacing vintage hardware, we carefully:

• Disassemble and inspect internal components
• Clean out old debris and oxidation
• Apply dry lubricants to improve operation without attracting dust
• Adjust set screws, latch depth, and bolt alignment for smooth engagement

If restoration isn’t viable, we offer two tailored solutions:

1. Install a new mortise lockset that matches your door’s vintage look and function.
2. Retrofit for modern hardware, improving security while respecting the home’s design.

Modern Lock Installation

Smart, Stylish, Secure – Locks Designed for Today’s Homes

We supply and install grade A modern locks engineered for performance, durability, and visual appeal. Our inventory includes leading brands like Schlage, Kwikset, Emtek, and Yale - offering everything from traditional keyed entries to keypad locks and smart locks integrated with home automation systems.

Perfect for:

• Front & back doors
• Side entry & garage access
• Interior bedroom or home office security

Our team will guide you in selecting lock styles that match your décor and meet your lifestyle needs, all backed by our workmanship warranty.

Surface-Mounted Lock Solutions

Fixing or Replacing Outdated Locks with Precision

Common on older wooden doors and brownstone entries, surface-mounted locks often suffer from wear, misalignment, or outdated components. These locks rely on rim cylinders and external latch mechanisms, which can fail if not maintained.

We inspect:

• Lock body alignment
• Cylinder rotation
• Mounting integrity

If your current lock is worn beyond safe use, we can install a modern surface-mounted unit that maintains the door’s structure while boosting your home’s safety and functionality.

Lock Rekeying

Regain Full Control Over Who Has Access

Rekeying is one of the most important steps for any homeowner after moving in, experiencing a break-in, or lending out keys to guests or workers. Rather than replacing the entire lock, we alter the internal pin configuration so old keys no longer work - rendering lost or stolen keys useless.

Ideal for:

• New homeowners
• Rental turnover
• Post-divorce or roommate changes
• Contractors with old key copies

It’s affordable, quick, and improves home security instantly without changing your door’s look.

Emergency Lockout Services

Locked Out? We’re On the Way - 24/7 Response

Nothing is more stressful than being locked out of your home, especially late at night or in poor weather. SherlockLock provides 24/7 emergency locksmith services across the Boston area. Our expert technicians arrive quickly, assess your door, and use non-destructive entry techniques whenever possible.

We service:

• House doors
• Apartments & condos
• Mailboxes
• Safes & cabinets
• Garage locks

If we must replace a lock due to damage or malfunction, we’ll work to match your existing key or rekey the new hardware so you’re back in control.

Master Key Systems

Efficient Access Control for Multi-Unit Homes and Landlords

A master key system gives one key access to all locks on a property while allowing restricted keys for individual users. It’s perfect for:

• Property managers
• Duplex & multi-unit homes
• Landlords with multiple rentals
• Families needing tiered access

SherlockLock designs, installs, and maintains custom master key systems for homes and small buildings. Each setup is documented clearly so future rekeys and upgrades are simple and secure.

Deadbolt & Lock Installations

Strengthen Your Entry Points with Proven Hardware

Deadbolts are a cornerstone of residential security. We install all forms of deadbolts, including single-cylinder, double-cylinder, and jimmy-proof varieties. We also reinforce strike plates and doorframes to ensure your new lock holds up under pressure.

Other installations include:

• Keyless smart locks
• Chain locks and swing bars
• Peepholes and door viewers
• Interior privacy locks
• Garage entry locks

Our work is clean, precise, and guaranteed to improve both safety and appearance.

High-Security Locks & Restricted Key Systems

When Security Can’t Be Compromised

Standard locks can be bumped, picked, or drilled by skilled intruders. SherlockLock offers high-security locks featuring:

• Pick-resistant cylinders
• Drill-resistant cores
• Heavy-duty bolts and strike hardware
• Restricted keyways, so copies can’t be made without your approval

Recommended for:
