Lock Rekeying Procedure
Eligibility Check (Can We Rekey This Lock?)
We inspect lock condition—worn cylinders with loose parts can't be reliably rekeyed and need replacement. If your lock is older than 15-20 years or shows heavy corrosion, replacement is usually more cost-effective long-term. Standard residential rekeys run $45-65 per lock (less for multiple), with same-key rekeying at $25 per additional lock when you want all locks using one key.
Cylinder Removal & Pin Configuration (10-15 Minutes/Lock)
We unscrew or pop out the cylinder (no door damage), dump out the old pins, and install new pin stacks cut to match your desired key code. Each lock has 5-6 pin chambers with top pins (drivers) and bottom pins (key pins). We swap bottom pins to match the new key bitting. If you want all locks on one key, we configure every cylinder identically—called "keying alike."
Key Cutting & Shear Line Testing
We cut new keys and test them in the follower plug before reassembly. Keys must align pins perfectly at the "shear line" where plug meets housing—even 0.005" off causes sticking. We cycle each lock 10-20 times checking for binding. If any key hesitates, we recut or adjust pin heights until operation is buttery smooth, crucial for deadbolts under spring tension.
Key Quantity & Future Proofing
Standard service includes 3 keys per unique configuration. Need more? Our key duplication team cuts extras on the spot for $3-5 each. We also store your key code for 2 years—if you lose all keys, call us and we'll cut new ones from memory without drilling your locks. Pro tip: get one extra set and hide it outside in a realtor lockbox ($30).

Frequently Asked Questions - Lock Rekeying Service St. Louis
Common questions about our professional lock rekeying service in the metro area and surrounding communities
How does lock rekeying differ from lock replacement?
Lock rekeying changes the internal pin mechanism so old keys no longer work, while keeping your existing lock hardware. This typically costs significantly less than full lock replacement. Rekeying is ideal when your locks are in good condition but you need new keys for security. Lock replacement or new lock installation is recommended when locks are damaged, worn out, or you want to upgrade to higher security levels.
How long does lock rekeying take in St. Louis?
Most lock rekeying jobs take 15-30 minutes per lock. A typical home with 3-4 locks can be completely rekeyed in 1-2 hours. The process is much faster than lock replacement since we're only changing the internal pins rather than removing and installing new hardware. We can often complete same-day service throughout the metro area.
Can all locks be rekeyed, or do some need replacement?
Most standard pin tumbler locks can be rekeyed, including deadbolts, door knobs, and many commercial locks. However, some locks may need replacement if they're severely worn, damaged, or use proprietary key systems. Our technicians will assess your locks and recommend the most cost-effective solution - rekeying when possible, replacement when necessary.
How much can I save with lock rekeying versus replacement?
Lock rekeying is typically much more cost-effective than lock replacement, often providing substantial savings while delivering equivalent security benefits. The exact cost depends on lock type, number of locks, and job complexity. We provide transparent, competitive pricing with no hidden fees for all rekeying services throughout our service area.
When should I rekey my locks instead of replacing them?
Rekey your locks when moving to a new home, after losing keys, when ending relationships, or when you want to eliminate access for former employees or tenants. Rekeying is ideal when your locks are in good working condition but you need new keys for security. If you want keyless convenience instead, consider our smart lock installation service. It's the most cost-effective way to ensure only you have access to your property.
Do you provide lock rekeying service for businesses in St. Louis?
Yes, we provide commercial lock rekeying service for businesses throughout the region including offices, retail stores, restaurants, and warehouses. We can create master key systems, rekey multiple locks to work with the same key, or provide different keys for different access levels.
