Emergency Home Lockout Service
There is nothing worse than the sinking feeling of realizing your keys are on the kitchen counter while you are standing on the front porch. We offer emergency locksmith services for homeowners and renters.
Non-Destructive Entry: Our skilled locksmiths use advanced lock picking and manipulation techniques (like bumping or picking) to open your door without drilling or damaging the lock hardware whenever possible.
Rapid Response Time: We understand the urgency. Our mobile vans are equipped to reach you quickly anywhere in St. Louis County, from Town and Country to North County, or Saint Louis, MO.
Broken Key Extraction: Did your key snap off in the lock? Don’t try to dig it out with a paperclip! We have specialized extractors to remove the broken piece and cut you a new key on the spot.
Rekeying vs. Changing Locks: What Do You Need?
One of the most common questions we get is, “Do I need to replace my locks or just rekey them?” As experts, we help you save money by choosing the right option.
Professional Lock Rekeying
Rekeying involves changing the internal pins of your existing lock cylinder so that old keys no longer work, but you keep the same hardware.
Best For: New homeowners, lost keys, or roommate turnover.
Benefit: Cost-effective and secure. You get a brand new set of keys without buying new handlesets.
Lock Replacement & Installation
Changing locks means removing the old hardware entirely and installing brand new locks.
Best For: Broken locks, worn-out hardware, or upgrading style/security.
Benefit: Upgrade to Grade 1 or Grade 2 residential hardware for better resistance against kick-ins.
Smart Locks & Keyless Entry Installation
Upgrade your home security with the latest digital door locks. We supply and install top brands like Schlage, Kwikset, and Yale.
Keypad Deadbolts: Never worry about hiding a spare key under the mat again. Enter a secure PIN code to unlock your door.
Smart Locks (Wi-Fi/Bluetooth): Control your locks from your smartphone. Grant access to dog walkers or contractors remotely and receive notifications when your door is unlocked.
Biometric Locks: Fingerprint access for high-security areas or home offices.

People Often Ask us
Pricing varies based on the time of day and the type of lock (standard vs. high security). We provide transparent, upfront pricing before we begin work. Call (314) 423-3720 for a quote.
Yes! If your locks are compatible (share the same keyway, e.g., all Kwikset or all Schlage), we can key them alike. This means one key opens your front door, back door, and garage door.
Yes, we provide fresh installation services for hardware you have purchased yourself. However, we also stock professional-grade hardware that often comes with better warranties than retail versions.
You should immediately rekey all exterior locks. You have no way of knowing how many copies the previous owners, their real estate agent, or their contractors still have.
