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.

The Ultimate in Home Security - Trusted Deadbolt Installation & Upgrades Across Greater Boston

When it comes to securing your home, deadbolts are one of the most effective and reliable locking mechanisms you can choose. At SherlockLock, we specialize in providing expert deadbolt installation, replacement, and upgrades tailored to the unique security needs of Boston-area homeowners.

Why Deadbolts Matter for Home Security

A deadbolt lock offers superior protection compared to standard spring bolt locks because it cannot be easily retracted without the correct key. This added resistance to forced entry makes deadbolts an essential part of your home’s security system, particularly on exterior doors.

Deadbolts act as a strong physical barrier against break-ins, giving you peace of mind that your family, valuables, and property are protected 24/7. Whether you’re upgrading an older home’s security or installing locks on a new door, a deadbolt is a must-have.

Types of Deadbolts We Install

At SherlockLock, we offer a wide selection of deadbolts to fit your security needs and budget:

Single Cylinder Deadbolts: Operated with a key from the outside and a thumb turn inside, ideal for most residential exterior doors.
Double Cylinder Deadbolts: Require a key on both sides, perfect for doors with glass panels where extra security is necessary to prevent unauthorized entry through broken glass.
Lock-Guard Deadbolts: Feature reinforced strike plates and hardened bolts to resist kick-ins and prying.
Smart Deadbolts: Electronic or keypad-controlled deadbolts that allow keyless entry, remote locking, and access control via smartphone apps.

Professional Deadbolt Installation & Replacement

Proper installation is critical for a deadbolt to perform as intended. Our certified locksmiths ensure:

Precise fitting to your door frame and door thickness
Secure placement of heavy-duty strike plates to resist forced entry
