Home Lockout Service in St. Louis
Being locked out of your home is stressful — especially at night or in bad weather. Armour Locksmith provides fast, non-destructive home lockout service throughout St. Louis. Our technicians use professional lock picking and bypass tools to open your door without damaging the lock, frame, or door panel.
Common home lockout situations we handle every day in St. Louis:

Lock Rekeying Service in St. Louis
Rekeying is one of the most important home security services a locksmith provides. When you rekey a lock, a technician removes the lock cylinder and replaces the internal pin tumblers so the existing key no longer works — and a new key is cut to the updated configuration. Your existing hardware stays in place, making rekeying faster and more economical than full lock replacement.
When should you rekey your St. Louis home locks?
- After purchasing a new home — previous owners and their contacts may have key copies
- After a break-in or attempted forced entry
- After losing or misplacing a key
- After a roommate, tenant, or domestic partner moves out
- After a contractor, house cleaner, or other service provider had key access
- As part of an annual home security review
Deadbolt Installation in St. Louis
A properly installed deadbolt is your single most effective residential security upgrade. Armour Locksmith installs and replaces deadbolts throughout St. Louis, recommending the right grade and style for your door type and threat level.
Key deadbolt specifications we work with:
- ANSI Grade 1 — highest residential security rating. Resists 10 kicks with 250+ lb force. We recommend Grade 1 for all exterior St. Louis home doors.
- ANSI Grade 2 — medium-duty residential use. Suitable for interior and secondary doors.
- Single cylinder deadbolt — key outside, thumb-turn inside. Standard for most residential applications.
- Double cylinder deadbolt — key required on both sides. Used where a glass panel near the lock creates a bypass risk.
- Reinforced strike plate — critical component often overlooked. We install heavy-duty 3-inch strike plates to resist kick-in attacks.
Top brands we install: Schlage B60N, Kwikset 980, Baldwin, Medeco, and more.
Smart Lock Installation in St. Louis
Smart locks and electronic keypads are the most requested residential upgrade for St. Louis homeowners. They eliminate the need for physical keys, allow multiple unique access codes, and enable remote monitoring and control from your smartphone.
Smart lock benefits for St. Louis homeowners:
- Create and delete access codes without physical re-keying
- Know exactly when your door was unlocked and by which code
- Grant temporary codes to house cleaners, dog walkers, or guests
- Lock or unlock your door remotely from anywhere with a smartphone
- Auto-lock feature ensures your door is never accidentally left unlocked
- No lockout risk — entry via code, fingerprint, or mobile app
Smart lock brands we install: Schlage Encode, Kwikset SmartCode, Yale Assure, August Smart Lock Pro, Ultraloq, Lockly, and more. We handle full installation including door prep, hardware fitting, and app configuration.
Home Security Lock Upgrades in St. Louis
Many St. Louis homes — particularly older properties in neighborhoods like Webster Groves, Kirkwood, Maplewood, and Soulard — have outdated lock hardware that does not meet modern security standards. Armour Locksmith assesses your current door hardware and recommends targeted upgrades to close vulnerabilities:
- Weak knob locks replaced with deadbolts — knob locks can often be bypassed in seconds without the key. Deadbolts provide the bolt throw and resistance knob locks lack.
- Strike plate upgrade — most door kick-ins succeed because a short screw in the strike plate pulls out of the door frame under force. A reinforced strike plate with 3-inch screws anchored into the studs dramatically increases kick resistance.
- Door frame reinforcement — add steel door frame armor to further resist forced entry.
- High-security lock installation — Medeco and Mul-T-Lock high-security cylinders resist picking, drilling, and key duplication without authorization.
- Sliding door and window lock upgrades — sliding glass doors are a common vulnerability. We install foot bolts, loop locks, and auxiliary locks to prevent forced sliding or lifting.
Safe Installation and Service in St. Louis
Armour Locksmith installs, opens, and services residential safes throughout St. Louis. Whether you need to secure firearms, important documents, cash, or valuables, we recommend and install the right safe for your specific needs. Safe options include:
- Fireproof document safes — protect paper documents, passports, and media from fire damage
- Floor safes — installed in the floor and covered, providing excellent concealment and theft resistance
- Wall safes — mounted in the wall and concealed behind a painting or panel
- Biometric gun safes — quick fingerprint access for secure firearm storage
- High-security TL-rated safes — for high-value contents requiring maximum protection
We also provide safe opening service if you are locked out of your safe or have forgotten the combination.

FAQ — Residential Locksmith St. Louis
How quickly can a locksmith reach me for a home lockout in St. Louis?
Armour Locksmith dispatches the nearest available technician immediately. Most St. Louis locations see response times under 30 minutes for home lockout calls. Emergency calls are always prioritized.
Is rekeying or replacing locks better for a new home in St. Louis?
Rekeying is typically the best choice when moving into a new home, provided the existing hardware is in good condition. It provides the same level of security as new locks at a fraction of the cost — the previous keys simply stop working. Lock replacement makes sense when the hardware is worn, damaged, outdated, or if you want to upgrade to high-security or smart lock technology.
Can a locksmith open a door without damaging the lock?
Yes. Professional residential locksmiths use non-destructive entry techniques — including lock picking and bypass tools — to open most locks without damage. Destructive entry (drilling) is a last resort used only when a lock is too damaged or secure to open otherwise. Armour Locksmith always attempts non-destructive entry first.
How many locks should I rekey when moving into a new house in St. Louis?
Rekey every exterior door lock, including the front door, back door, garage entry door, and any other door with a keyed lock that accesses the interior of the home. Do not forget sliding door locks or padlocks on outdoor gates if they use the same key. Armour Locksmith can rekey all locks in a single visit.
What smart lock brands do you install in St. Louis?
We install all major smart lock brands including Schlage Encode, Schlage Sense, Kwikset SmartCode, Kwikset Kevo, Yale Assure, August Smart Lock Pro, Ultraloq, and Lockly. We can also advise on which model best fits your door type, security needs, and smart home ecosystem.
Can you rekey multiple locks to the same key in St. Louis?
Yes. Keying multiple locks alike — so one key opens all of them — is a very common and convenient service. Armour Locksmith rekeys all your exterior door locks to a single master key during one visit, eliminating the need to carry multiple keys.
What should I do after a home break-in in St. Louis?
After contacting the police and filing a report, call Armour Locksmith for emergency security restoration. We will repair or replace damaged door hardware, rekey undamaged locks, and assess any vulnerabilities that contributed to the break-in. We provide 24/7 emergency response throughout St. Louis.

Window and Sliding Door Lock Services
Many St. Louis home break-ins occur through secondary entry points like windows and sliding glass doors, not just the front door. Armour Locksmith provides comprehensive residential security that covers all entry points:
- Sliding door locks — we install dual-point locking bars and security pins to prevent sliding doors from being lifted off the track or forced open
- Window locks — sash locks, keyed window locks, and charlie bars for basement and ground-floor windows
- Garage door lock reinforcement — deadbolt side locks and cable locks to prevent forced garage door entry
- Door reinforcement — strike plate upgrades (3-inch screws into studs), door frame armor, and door hinge reinforcement
A front door with a high-security deadbolt is only as strong as the weakest entry point in your home. Our residential security consultations cover your entire home, not just the front door.
Rekeying vs. Lock Replacement — Which Is Right for You?
| Situation | Recommended Solution | Why |
|---|---|---|
| Moving into a new home | Rekey all locks | Previous owners and their contacts may have copies |
| Lost or stolen keys | Rekey (if lock is in good condition) | Faster and costs less than full replacement |
| Locks are old or worn | Replace locks | Worn locks can fail and are easier to pick |
| After a break-in | Replace with high-security locks | Compromised locks should not be trusted |
| Want keyless entry | Replace with smart lock | Smart locks require full replacement of lock hardware |
| Landlord/tenant turnover | Rekey | Quick, cost-effective, confirms new key control |
| Adding a master key system | Rekey to master system | Requires cylinder repinning for master key hierarchy |
