Lock Installation St. Louis
Moving into a new home, upgrading from builder-grade, or replacing worn-out hardware? A1 Express Locksmith provides professional lock installation services in St. Louis, MO — we install Grade 1 and Grade 2 deadbolts, knob sets, lever handles, and complete door hardware with precision and care.
Choosing the Best Locks for Your Doors
Choosing the best locks for your doors can be challenging, especially if you have just moved into a new place. Every home's front door lock should be in perfect condition. While a good lock may not entirely prevent a break-in, it can definitely give an intruder something to deal with. However, you will be inviting in burglars if your locks are not top quality or are getting rusty. With the help of A1 Express Locksmith, we can determine what type of lock would best replace the old ones. Whether deadbolt locks, smart locks, or keyless entry locks, we help you make the best decision for your home. Security is always important, no matter how safe you perceive a neighborhood to be.
Lock Installation for New Homeowners
Moving into a new home is the single most important time to install new locks. You have no idea how many copies of the previous owner's keys exist — with neighbors, dog walkers, housekeepers, contractors, family members, and who knows who else. Our lock installation service in St. Louis provides complete front door, back door, side door, garage entry, and patio door lock replacement for new homeowners. We can key all your new locks alike so one key opens every exterior door. It is the first security upgrade every new homeowner should make, and we make it fast and affordable.
Our Lock Installation Standards
Every lock installation by A1 Express follows the same quality standards: the lock is mounted square and level with no gaps between the faceplate and the door edge. The strike plate is aligned so the bolt slides in smoothly with no rubbing. The strike screws are three-inch case-hardened screws driven into the wall framing. The key turns easily in both directions. The latch and deadbolt operate smoothly with one finger. The door closes securely and the weatherstripping seals properly. We clean up all drilling debris and old hardware before we leave. Your door looks like the lock was always meant to be there.
Lock Brands We Trust and Install
Schlage, Kwikset, Yale, Baldwin, Emtek, and Medeco — these are the brands that have earned their reputation through decades of reliable security. We install them because they hold up to daily use, resist picking and bumping, and carry real manufacturer warranties. We do not install no-name hardware or imported locks of questionable quality. Every lock we sell comes with the manufacturer warranty and our lifetime workmanship guarantee on top. If a lock we installed fails, we replace it. Simple.
Lock Installation Questions, Answered
How much does lock installation cost?
Pricing varies based on the number of locks, the grade and brand of hardware, and whether door modification is needed. We quote flat-rate, itemized pricing upfront so there are no surprises.
Can you install locks on old or damaged doors?
Yes. We repair split jambs, fill old holes, reinforce thin doors, and realign sagging frames before mounting the new lock. The door must be sound before the lock can do its job.
Should I replace all my locks at once?
If you just moved in, yes — it is the safest approach. If you are upgrading, you can phase the work by starting with the most vulnerable doors: front, back, and any door hidden from street view.
Do you sell the locks or do I provide them?
We carry professional-grade inventory in our vans for same-day installation. You can also purchase your own hardware and pay only our installation labor.
