Rekey vs Replace Locks After Moving Into a Dallas Home

Two weeks ago I pulled up to a new client's house off Greenville Ave in Lakewood. She'd closed on the place Friday, moved in Saturday, and called me Sunday morning. Her question is one I get every single week: "Do I really need to change all the locks, or can you just rekey them?"

Short answer: in about 80% of moves, rekeying is the right call. But there are real cases where full lock replacement is smarter. Here's how I help homeowners decide — and what each option actually costs in Dallas right now.

Why You Should Never Skip This Step

When you get the keys at closing, you have no idea who else has a copy. The previous owner's cleaning service. The handyman from 2019. The realtor's lockbox key. The neighbor who watered the plants. The contractor who finished the bathroom remodel. I've personally rekeyed homes where the seller handed over six keys at closing and the new owner found three more taped to the inside of a kitchen drawer two weeks later.

The 60-second cost-benefit math: rekeying a typical Dallas home runs $80–$160 total. The downside of not doing it can be a four-figure burglary loss with no signs of forced entry — which means your insurance company will fight the claim.

What Rekeying Actually Means

Rekeying changes the internal pin configuration of your existing lock so the old key no longer turns it. The lock body, the deadbolt, the strike plate — all of it stays. We just pop out the cylinder, swap the pins to a new pattern, and cut you a fresh set of keys.

When rekeying is the right move

• The locks are less than 10 years old and still operate smoothly
• They're a recognized brand (Schlage, Kwikset, Baldwin, Yale)
• You want every door on one key
• Budget matters and the locks aren't damaged
• You're in a typical Dallas single-family home in a low-to-moderate risk area

Typical Dallas rekey pricing

• Per cylinder rekey: $20–$35
• Service call / trip fee: $35–$65
• Average 3–5 door home: $115–$200 total
• Same-key matching across all doors: included
• Extra keys cut: $4–$8 each

When You Should Actually Replace the Locks

Sometimes I show up, look at what's on the door, and tell the homeowner straight up: rekeying these isn't worth it. Here's when full lock installation makes more sense.

Replace if you see any of these

• The lock is loose, sticky, or the key wiggles. Internal wear means the pins won't seat cleanly even after a rekey.
• It's a builder-grade big-box-store deadbolt. A lot of Dallas tract homes from 2005–2015 have ANSI Grade 3 locks that you can defeat with a screwdriver in 90 seconds. Rekeying a bad lock just gives you a new key for a bad lock.
• The strike plate uses 3/4-inch screws. This is the single most common security failure I see in Dallas homes. Doesn't matter how good the lock is — one solid kick and the door frame splinters.
• You want smart features. If you're going smart anyway, skip the rekey and go straight to a smart lock install.
• The previous owner had a rental, Airbnb, or estate sale. Too many unknown copies in circulation. I'd rather start clean.
• Mismatched hardware on different doors. Replacing gets you uniform keying and matching finishes.

Typical Dallas replacement pricing

• Standard Grade 2 deadbolt installed: $95–$165 per door
• Grade 1 commercial-grade deadbolt: $175–$275 per door
• Smart deadbolt installed (Schlage Encode, Yale Assure): $245–$425 per door
• Full keyed-alike 4-door package: $380–$650 typical

A Real Dallas Example

Last month I worked a 1940s bungalow off Mockingbird in Lakewood. The owner had just closed and called for a "rekey on five doors." I got there and found three different lock brands, two were Kwikset SmartKey (which has a documented bumping vulnerability), one back door deadbolt was loose enough to wiggle in the frame, and the strike plates were all factory 3/4-inch screws.

I gave her the honest breakdown: rekeying everything would have run $180 and left her with the same weak hardware. Instead we did two new Grade 2 deadbolts on the front and back ($310 installed with 3-inch screws and reinforced strike plates), rekeyed the side door and garage entry to match ($55), and replaced one knob set ($85). Total: $450 — about $270 more than a straight rekey, but she now has actual security on the two doors that matter most.

That's the conversation worth having before you make the call.

The Hybrid Approach (My Most Common Recommendation)

For most Dallas homes I service, the smartest play is a mix:

1. Replace the front door deadbolt with a Grade 2 or smart lock — this is the door burglars target first
2. Replace the door from the garage into the house — second most common entry point, almost always neglected
3. Rekey everything else to match the new front door key

This usually lands in the $250–$425 range for a typical Dallas home and gives you real protection where it matters without overspending on side doors and back gates.

What About the Garage Door Opener and Mailbox?

Two things people forget on move-in day:

• Garage door opener codes. Reset them. Most modern openers have a "learn" button — hold it down for 6–10 seconds to clear all paired remotes, then re-pair only your own. Takes five minutes.
• Mailbox lock. If it's a cluster mailbox, contact USPS for a new key ($25–$50 fee). If it's a wall-mount or curbside box with a lock, we can rekey or replace it for $35–$75.

How Long Does All This Take?

A standard 4-door rekey in a Dallas home takes me 30–45 minutes once I'm on site. A full replacement of 2 deadbolts plus rekeying the rest is usually 60–90 minutes. Same-day service is almost always available — most of my move-in calls go out within 2–4 hours of booking.

If you just closed and you're reading this on closing day, you're not behind. Get it on the calendar this week. And if you ever do get locked out before we get there, you've got our number.

Final Recommendation

Rekey if your locks are decent, modern, and tight. Replace if they're weak, worn, or builder-grade. Mix the two approaches for most homes. And whatever you do, don't skip this step — it's the cheapest insurance policy on the entire move.
