Locksmith Coverage From Chesterfield Valley to Olive Blvd

Chesterfield has a lot of late-model luxury and near-luxury vehicles, and those smart keys can cost a fortune at the dealer — if the dealer can even get you in this week. We program many of them at your vehicle, and we'll tell you honestly up front if a particular model is dealer-only.

On the home side, Chesterfield homeowners often want more than a basic rekey: high-security locks that resist picking and bumping, smart deadbolts that work with a phone app, and matching hardware across front, side and garage doors. For businesses in the office corridor along I-64 and Chesterfield Airport Road, we design master key systems that scale with your team.

Chesterfield Locksmith FAQ

Can you make a smart key for my 2018 Lexus ES 350 if I lost it in Chesterfield Valley?
In most cases, yes. We supply and program a new smart key for the 2018 ES 350 at the vehicle and cut the emergency blade. Call with your VIN so we can confirm the part and give you a firm price.
I lost the key to my 2017 Acura MDX. Can you erase the old key from the car?
Yes. When we program a new key for the MDX, we can remove the lost key from the car's memory so it can no longer start the vehicle — important if the key may have been stolen.
Do you install high-security locks in Chesterfield homes?
Yes. We install pick- and bump-resistant high-security deadbolts with restricted keys that can't be copied at a hardware store — a good fit for homeowners who want real control over who has a key.
Can you program a key for a 2016 Cadillac Escalade?
Yes. We program smart keys for the 2016 Escalade on-site, both as spares and when all keys are lost.
Do you make keys for a 2019 Lincoln Navigator?
Yes. We supply and program proximity smart keys for the 2019 Navigator. Adding a spare while you still have a working key saves money.
Can you set up a master key system for my office on Chesterfield Airport Road?
Yes. We design master key systems so owners and managers carry one key while staff only open their own areas. We document every key so you always know who has what.
I'm locked out of my car at Chesterfield Commons. Do you come to shopping centers?
Yes. Tell us which store you're near and we'll give you an honest ETA. Most car lockouts are opened damage-free in minutes.
Can you change the combination or open a home safe in Chesterfield?
Yes. We open most residential safes, change combinations on mechanical and electronic locks, and repair safe locks that have failed.
Do you install smart locks that work with an app?
Yes. We install and set up smart deadbolts from Schlage, Yale, Kwikset and others, and we'll make sure the door is aligned so the bolt throws smoothly — a common reason smart locks fail.
Can you rekey a condo or townhome in Chesterfield?
Yes. We rekey unit doors, mailbox locks and storage locks, and we coordinate with your HOA if the building has master-keyed common doors.
What are your hours in Chesterfield?
Regular hours are 6 AM to midnight, 7 days a week. For emergencies — a lockout, lost car keys, or a door you can't secure — our emergency line is answered 24/7. Call or text 636-254-9469.
