About SherlockLock Residential Locksmith Services

In depth guide to our services:

Lock Repairs
We prioritize repairing locks over replacing them whenever possible, as it’s more cost-effective and resourceful. However, some locks are beyond repair or of low quality and need replacement. Our service vans are stocked with replacement parts and a variety of locks. Many issues can be diagnosed and priced over the phone based on your description.

Old Locks & Mortise Locks
Older homes in the Boston area often have vintage lock hardware that may need servicing or replacement. Mortise locks, commonly found in high-end properties, are durable and decorative. We recommend restoring these by cleaning and repairing internal components. If replacement is necessary, we offer two options:

1. Replace with a new mortise lock for quality and aesthetic value.
2. Retrofit the door for a modern, durable lock, often a cost-effective choice.

Modern Locks
We carry only A grade locks for durability and can recommend decorative options to suit your style, provide warranty on our job.

Surface-Mounted Locks
These older locks, operated by rim cylinders, often suffer from alignment issues or wear. When needed, we replace them with high-quality alternatives.

Lock Rekeying
Rekeying changes a lock's internal components to prevent old keys from working. It’s a cost-effective solution that requires specialized skill and parts.

Lockout Services
We provide quick and efficient lockout assistance for homes, cars, safes, mailboxes, and more. Most locks can be picked or bypassed without damage. If replacement is necessary, we ensure it matches your existing key whenever possible.

Master Key Systems
A master key system allows one key to operate all locks, with sub-keys providing restricted access. Ideal for landlords and property managers, this setup ensures convenience and security.

Deadbolt & Lock Installation
Installing a deadbolt enhances home security. We also install strike plates for added protection and can fit various other locks, including jimmy-proof deadbolts, chain locks, and peep holes.

High-Security Locks & Restricted Keys
High-security locks are resistant to picking, drilling, and tampering. Restricted keys can only be copied with authorization, offering better control over access—ideal for landlords and businesses.

Security Advice and Upgrades by SherlockLock

Expert Guidance to Strengthen Your Home’s Defense – Personalized Solutions for Greater Boston Residents

Your home’s security is only as strong as its weakest point. At SherlockLock, we go beyond standard lock services by offering comprehensive security consultations and upgrade solutions tailored to your property layout, lifestyle, and risk level. Whether you're dealing with outdated hardware, recent neighborhood crime, or preparing a rental unit for new tenants, we help you make smart, lasting improvements that protect what matters most.

Why Invest in a Home Security Upgrade?

Modern threats require modern defenses. Even a high-quality deadbolt can fall short if it's paired with a weak frame, unsecured windows, or outdated access controls. Upgrading your residential security gives you:

Greater peace of mind
Improved resistance to break-ins and tampering
Better control over who has access
A stronger deterrent against opportunistic crime
Increased property value and tenant appeal (for landlords)

We bring the latest security hardware, techniques, and product knowledge to every job - ensuring you receive a solution that fits your needs without overspending.

Our Home Security Services Include:

🔐 Full Home Security Audits
We assess every entry point - front, side, back, basement, garage, and windows - to identify vulnerabilities. You'll receive clear recommendations backed by industry best practices.

🚪 Lock Upgrades
Replace worn or standard-grade locks with high-security deadbolts, restricted key systems, or smart locks that provide keyless control and remote access.

🛡️ Strike Plate & Door Reinforcement
We install reinforced strike plates, long screws, and door edge armor to protect against kick-ins and forced entry.

🔑 Key Control Systems
We implement restricted keyways that prevent unauthorized copies - ideal for landlords and multi-unit dwellings.

📲 Smart Home Integration
Upgrade to electronic or Wi-Fi-enabled locks that let you monitor and manage access through your smartphone, with audit trails, guest access codes, and remote locking features.

🎥 Security Hardware Add-ons
We install door viewers (peep holes), door chains, window locks, and coordinate with alarm and camera systems if needed.
