Rekey your new home before you start unpacking
Closing on a home is one of the best feelings there is. The thing most people don’t stop to think about that day is that the keys you’re handed are rarely the only set that works on the house. Over the years, the previous owners probably gave spares to all kinds of people. A neighbor who watered the plants, a house cleaner, a dog walker, a relative who stayed for a while, maybe a contractor who kept one after a remodel and never gave it back. On plenty of sales, the listing agent’s lockbox sat on the front door for weeks, with showing after showing running through it.
So before the moving truck even shows up, the smartest move is to rekey the locks, and a good rekey service in Dallas, TX takes far less time than most people expect. Most folks put it off until everything else is unpacked and settled. Honestly, it belongs near the top of the list, right alongside getting the power and water switched over.
Who else still has a key to your home
That list of spares is bigger than most people realize, and there’s no paperwork that tracks any of it. A key gets copied at a hardware store in about two minutes, and nobody writes it down anywhere. With newer construction it is worse, because the same builder’s key opened the house for months while different crews came and went.
Here’s the part people miss. The locks look fine and turn fine, so it’s easy to assume you’re secure. What you don’t know is who else can still unlock the door. On most move-in calls the hardware’s already in good shape, so rekeying your locks in Dallas isn’t about replacing anything. It just resets who can get in, and Texas Premier Locksmith handles the whole house in one trip.
The new-mover rekey checklist
Here’s the checklist we run through with new homeowners. It covers every lock that actually matters, including a few that are easy to walk right past. Most of these get handled in the same visit, so you’re not booking a locksmith five separate times.
- Front, back, and side entry doors. Side and back doors get skipped all the time, and those are the ones burglars actually go for because nobody’s watching them. If an old key still works on the back door, that’s the one that’ll get used
- The door from the garage into the house. This is the one almost everyone forgets. It sits inside, so it never feels like an outside door. It still is one, and if someone ever gets your garage remote, that lock’s the only thing between them and your living room. We end up rekeying that door on nearly every job.
- Detached garage, shed, or workshop. Anything on the property that locks should go on the list. These usually run on old, cheap hardware nobody’s touched in years, which makes them an easy way in. That’s also where the ladders and power tools live, which is exactly what a thief wants.
- Gates, pool locks, and side fences. Plenty of Dallas homes have these. A pool gate matters even more, since that’s about safety as much as security, especially with kids around.
- The mailbox. It feels minor, but a lot of identity theft starts at an unsecured curbside box. A shared community box is the HOA’s job, but your own box is quick to handle. Mail theft is a slow-burn problem, and you usually don’t notice until a bill or a new card never shows up.
- Smart locks and keypads. Changing the visible code isn’t enough on its own. Do a full factory reset so every saved fingerprint and app user from the old owner gets wiped. Resetting just the code leaves their access sitting in place. We’ve shown up to homes where the previous owner could still unlock the door from their phone.
What it costs depends on how many locks you have and what each one needs, so it’s worth getting a quick quote first. In most cases, rekeying still comes in under the price of replacing every lock in the house. For real local numbers, a Dallas locksmith can give you a straight answer, and our guide on how much it costs to rekey your house lays it out.
Expert Tip
While everything’s still working, it’s worth getting a spare key cut during the same visit. It’s cheap and quick to do at this stage. Once you’ve lost your only key, the locksmith has to start from scratch, and making a brand-new key from nothing takes longer and costs more. A spare also bails you out on the bad days, when you’re locked out, running late, or someone else in the house needs a key of their own.
A few Dallas-specific things people miss
A few issues come up regularly on Dallas-area move-in calls, and a standard home inspection won’t flag any of them. Most first-time buyers only run into them a week or two after moving in, usually right at the moment they turn into an actual headache. A little heads-up now saves you that scramble later. Here are the ones worth knowing before you settle in.
- HOA gate fobs and amenity keys. If you’re buying into a gated community or somewhere with a shared pool or gym, the seller’s fobs often don’t transfer the way you’d expect. We see new homeowners run into this all the time, because HOA offices can take several days to issue new ones. Get the count of working fobs in writing at closing so you know exactly what’s missing, and sort it out early so you’re not stuck outside your own amenities the first week.
- Builder and master keys on new construction. A newly built home almost always ran on a builder’s master key during construction, and that key’s sometimes shared across a whole row of houses. A brand-new lock feels secure, but it isn’t really yours until the builder key gets rekeyed out. We see this constantly in the newer Dallas suburbs.
- Rental-to-owner transitions. If the home was a rental before you bought it, assume old tenants and their friends might still have keys. There’s almost never a record of who got one, so this is an easy call to rekey. The same goes for a house that sat through dozens of showings before it sold.
- Heat-warped and sun-baked hardware. Texas summers are hard on door hardware. A lock that sticks or needs a shoulder to turn is usually fighting the heat, not age. Flag the rough ones early, because a lock that finally gives out in July has a way of stranding you on the porch with a car full of groceries.
Rekey or replace, the quick version
For most new homeowners, rekeying’s the right call unless there’s a real reason to replace. It resets the internal pins so old keys stop working, keeps your current hardware, and costs less. Replacing locks only makes sense when they’re damaged or worn out, or when you want to step up to higher security or smart locks. If you’re going that route anyway, it’s worth pricing both at once so you’re not paying for two visits. For the full comparison, we covered it in rekeying vs. changing locks.

Frequently Asked Questions
How long does a whole-house rekey take?
Most homes can be rekeyed in well under an hour. Bigger places with more doors take a little longer, but it’s still a same-visit job in nearly every case.
Can every lock open with the same key?
Yes. As long as the locks share the same brand and keyway, we can key them alike so one key works the whole house. Just mention it when you book, since it costs nothing extra during the same visit.
Do I need to rekey a newly built home?
Yes. A new home runs on a builder’s key all through construction, and that key’s often shared across several houses. The locks are new, but they aren’t only yours until they’ve been rekeyed.
