Residential Lock Replacement in Memphis, TN

There comes a point where a lock has done its job for long enough. The deadbolt is stiff. The knob barely catches. The hardware is 20 years old and two generations behind current security standards. Or maybe the situation is more urgent: a break-in attempt damaged the lock, you just moved into a new home and want fresh hardware, or a key broke off inside the cylinder and destroyed it from the inside out.

Whatever the reason, Locksmith 4 Less removes old locks and installs new ones at your home. We carry a selection of deadbolts, knob locks, lever handles, and keyless entry systems on our service vans, so most replacements are completed in a single visit. Licensed, insured, and serving the entire Memphis service area.

When to Replace vs. When to Repair or Rekey

Do You Actually Need New Locks?

Not every lock problem requires a full replacement. Sometimes a repair fixes the issue for a fraction of the cost. Other times, a rekey is all you need to restore your security. Here is how to tell which situation you are in.

Replace when

The lock is physically damaged. The bolt or latch mechanism no longer extends or retracts properly. The lock body is cracked, corroded, or visibly worn. The hardware is so old that replacement parts are no longer available. You want to upgrade from a basic lock to a higher-security option. The lock was compromised during a break-in or attempted break-in.

Repair when

The lock works inconsistently but still functions. A specific component like a spring, tailpiece, or set screw has failed. The lock is stiff or sticky due to dirt buildup or misalignment rather than a broken mechanism.

Rekey when

The lock hardware is in good condition but you need to make sure old keys no longer work. You just moved into a new home. You lost a key. You ended a relationship or let go of someone who had a copy.

If you are not sure which option is right, call us. We assess the lock in person and give you an honest recommendation. We would rather fix a $15 problem than sell you a $150 replacement you do not need.

Types of Locks We Install

Lock Options for Your Home

We carry a range of residential lock hardware on our vans and can source additional options for scheduled appointments. Here is what we install.

Single-cylinder deadbolts.

Keyed on the outside, thumb turn on the inside. This is the standard deadbolt configuration for most homes and the one we install most often. The deadbolt is the most important lock on any exterior door because it resists forced entry far better than a doorknob lock alone.

Double-cylinder deadbolts.

Keyed on both sides. These are used on doors with glass panels or sidelights where an intruder could break the glass and reach in to turn a thumb turn. Double-cylinder deadbolts prevent that. One important note: in a fire or emergency, you need a key to get out, so keep a key accessible near the door at all times.

Grade 1, Grade 2, and Grade 3 locks.

Locks are rated by the American National Standards Institute (ANSI) on a three-tier grading system. Grade 3 is the basic residential standard. Grade 2 is heavier duty and recommended for exterior doors. Grade 1 is commercial-grade and provides the highest level of security. We install all three grades and can help you decide which one fits your situation and budget.

Knob locks.

Standard doorknob locks with a keyed cylinder. We install these on exterior and interior doors, but we always recommend pairing a knob lock with a deadbolt on any exterior door. A knob lock by itself is not sufficient to resist a forced entry.

Lever handle locks.

Used on interior doors, hallway doors, and in homes where accessibility is a consideration. The lever handle is easier to operate than a round knob, making it a practical choice for children, elderly residents, and anyone with limited hand strength.

Keypad and smart locks.

Electronic locks that use a code, an app, a fingerprint, or Bluetooth to unlock the door. We install and configure these systems, including models from Schlage, Kwikset, Yale, and August. If you want to eliminate physical keys entirely, this is the path.

The New Homeowner Lock Change

Just Bought a Home? Change or Rekey the Locks Immediately

This is the most common reason Memphis homeowners call us for lock replacement, and it is one of the most important things you can do after closing on a new house.

When you buy a home, you have no way of knowing how many copies of the existing keys are out there. The previous owner may have given keys to family members, neighbors, pet sitters, housekeepers, contractors, real estate agents, and anyone else who needed access over the years. Some of those people may still have their copies.

Rekeying is the most affordable solution if the existing locks are in good condition. But if the home has older hardware, builder-grade locks, or locks that are showing wear, a full replacement makes more sense. You get fresh, higher-quality hardware with a clean set of keys, and you start with a security baseline you can trust.

We handle new homeowner lock changes across Memphis, Germantown, Collierville, Bartlett, and the rest of the metro. If you just closed on a house, call us and we will get your locks taken care of before you unpack the first box.

After a Break-In

Lock Replacement After a Break-In or Attempted Break-In

If someone forced entry into your home or tried to, the locks involved need to be replaced, not repaired. A lock that has been kicked, pried, or drilled may still appear functional, but the internal components can be bent, cracked, or weakened in ways that are not visible from the outside. A compromised lock is a lock you cannot rely on.

After a break-in, here is what we do:

We assess every exterior lock on the home, not just the door that was targeted. If the intruder got in through one door, they may have also attempted other entry points. We replace any lock that shows signs of forced entry, tampering, or damage. We install new hardware that meets or exceeds the security level of what was there before. If the door frame was damaged during the break-in, we let you know so you can have it repaired by a contractor. A new lock on a split frame does not provide full security.

We can also rekey any locks that were not damaged so that any keys the intruder may have had access to are no longer valid.

If you have experienced a break-in, call us. We handle the full lock assessment and replacement in a single visit, and we are available 24/7 through our emergency locksmith service.

Keyed-Alike Service

One Key for Every Lock in Your Home

One of the most common requests we get during a lock replacement is to set up every exterior lock to work with the same key. This is called “keyed-alike” service, and it means you carry one house key that opens your front door, back door, side door, and garage entry door.

We configure this during the installation process. Every new lock is pinned to match the same key profile, and you walk away with a set of identical keys that work on every door. If you are replacing some locks but keeping others, we can rekey the existing locks to match the new ones so everything works together.

This is especially useful for families with multiple people who need house keys. Instead of managing four or five different keys for different doors, everyone carries one.

FAQ

Lock Replacement Questions

How long does it take to replace a lock?

A single lock replacement typically takes 15 to 30 minutes. If you are replacing multiple locks across the house, we handle them in sequence and most full-home jobs are finished within a couple of hours.

Can you match my new locks to my existing key?

In many cases, yes. If you are keeping some existing locks and replacing others, we can rekey the new locks to match the key from your existing hardware, or rekey everything to a new key. Either way, you end up with one key for the whole house.

Do I need a deadbolt on every exterior door?

We strongly recommend it. A doorknob lock alone is not enough to resist forced entry. Every exterior door should have a deadbolt.

What brand of locks do you install?

We carry and install locks from Schlage, Kwikset, Yale, and other major residential lock manufacturers. We can discuss options and help you choose based on your security needs and budget.

Can you install a smart lock on an older door?

In most cases, yes. Smart locks are designed to fit standard door preparations. If your door has an unusual configuration, we assess it on-site and let you know what will work.

How much does a lock replacement cost?

Pricing depends on the type and quantity of locks. We provide upfront pricing over the phone. No hidden fees, no surprise charges.
