Lock Installation in Delaware — Deadbolts & More

Need a new deadbolt on your front door? Want to upgrade your whole home? Premier Locksmith installs and replaces all types of home locks across Delaware — same day, at flat-rate prices. We are Delaware licensed, bonded, insured, and ALOA-certified with over 10 years of local experience.

Overview

What Is Lock Installation and Replacement?

Lock installation fits a new lock onto a door that has none or needs a different one. Lock replacement removes an old or worn lock and puts a new one in its place. Both jobs need precise measuring and fitting to make sure the lock secures your door fully from day one.

A poorly fitted lock gives false peace of mind. Premier Locksmith fits every lock to the exact spec of your door — right backset, right bore size, right strike plate — so it works from the first use.

How It Works

Our Process

1

Call (302) 603-1775

A live tech picks up right away. Tell us the lock type you need and where you are in Delaware. We give you a flat-rate price on the phone and book a same-day visit in most cases.

2

We Check Your Door First

Our tech checks your door thickness, bore hole size, backset, and frame before touching a single tool. The right lock depends on these numbers — not guesswork.

3

Lock Fitted and Tested

We install your new lock, fit the strike plate, and test the bolt and key turn multiple times before we leave. Every lock we install works smoothly on the first use.

4

Spare Keys and Rekeying

Once the lock is fitted, we cut spare keys on-site if needed. If you want all your doors on one key, we handle that in the same visit at no extra call-out charge.

Lock Types

Types of Locks We Install in Delaware

Deadbolt Locks

Deadbolts are the most secure standard lock for home doors. Premier Locksmith installs single and double-cylinder deadbolts on all standard door types. We stock ANSI Grade 1 deadbolts from Schlage, Kwikset, and Baldwin.

Knob and Lever Locks

Knob and lever locks are common on interior and some exterior doors. We install and replace both types on all standard door sizes. For exterior use, we always pair a knob or lever with a deadbolt above it.

Smart and Keypad Locks

Premier Locksmith installs and sets up August, Schlage Encode, Kwikset Halo, and Yale smart locks. These locks use PIN codes, phone apps, or fingerprint readers. We set up the app, test the link, and walk you through how it all works before we leave.

High-Security Locks

Premier Locksmith installs Medeco and Mul-T-Lock high-security cylinders for homeowners who want stronger cover. These locks resist picking, bumping, and drilling. They also use restricted keyways — copies cannot be cut without your sign-off.

Rim Locks and Mortise Locks

Older Delaware homes often use rim or mortise locks. Premier Locksmith installs, replaces, and services both types. We also upgrade older setups to modern hardware where the door allows it.

Timing

When Should You Replace Your Locks?

After a Break-In or Forced Entry

A lock that has been forced or drilled is weakened — even if it still turns. Premier Locksmith replaces damaged locks and checks the door frame and strike plate at the same time.

When Locks Are Worn or Hard to Turn

A stiff or loose lock means the inner parts are worn. Worn locks fail more often and are easier to force open. Replacing them early costs far less than dealing with a break-in later.

When Moving Into a New Home

You have no way of knowing how many copies of the old keys exist. Replacing or rekeying locks on move-in day is the safest first step for any new Delaware homeowner.

When Upgrading Security

Standard builder-grade locks offer basic cover at best. Upgrading to ANSI Grade 1 deadbolts or high-security cylinders adds real, measurable protection to your home.

FAQ

Common Questions

A standard deadbolt or knob lock swap takes 20 to 30 minutes per door. A new install on a door with no existing bore hole takes 30 to 45 minutes. Smart lock installs run 45 to 60 minutes due to app setup and testing.
Most standard doors accept smart lock installs with no changes. Doors need a deadbolt bore hole of the right size and a flat surface for the housing to sit flush. Our tech checks your door first and tells you straight away if any prep is needed.
If your lock is in good shape and you just want new keys, rekeying costs less and takes less time. If your lock is worn, damaged, or low grade, replacing it makes more sense. We check your lock and give you an honest answer before starting any work.
ANSI Grade 1 is the top rating for home deadbolts in the U.S. A Grade 1 lock withstands at least 10 door kicks and 250,000 open and close cycles in testing. Premier Locksmith fits Grade 1 locks from Schlage and Kwikset as standard for all exterior doors.
Price depends on the lock type and number of doors. Standard deadbolt installs start at a flat rate covering parts and labour. Smart lock and high-security installs cost more due to hardware prices. Call (302) 603-1775 for a full quote before anyone comes out.
