Fast, Reliable Lock Installation & Rekey Across Detroit
Lock installation and rekeying in Detroit typically runs $120-$380 for most residential jobs, with same-day service available across the city. Our Lock Installation & Rekey team carries the specialized tools and period-correct hardware needed for Detroit’s pre-war housing stock, and we quote a flat price on the phone before any truck rolls.
We’ve been answering calls from Detroit homeowners for over 42 years, from the brick bungalows of 48208 to the two-family flats lining Warren Avenue. The houses here are different from the suburbs. The locks are different. The problems are different. A technician who knows Detroit knows that a mortise lockset in a 1925 foursquare demands a different approach than a standard cylindrical deadbolt in a Dearborn ranch. We keep Schlage, Baldwin, and Medeco hardware stocked for Detroit’s older homes, and our trucks carry de-icer and cylinder extraction tools as standard equipment from January through March.
Call (877) 664-8139. A live person answers, 24/7. We’ll give you a real price and a real arrival window.
Why Strongbox Lock & Safe Co. Is Detroit’s Preferred Lock Installation & Rekey Company
Detroit homeowners call us because we’ve earned a reputation for showing up when we say we will and charging what we quoted. No bait-and-switch. No “service call” surprises. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument to win.
Our response time to Detroit neighborhoods averages 35-50 minutes during business hours, and our emergency lockout service runs 24/7 including nights, weekends, and holidays. We know the difference between a mortise lock in a Boston-Edison foursquare and a rim cylinder on a Jefferson-Chalmers bungalow because we’ve worked on both, hundreds of times.
Every technician is background-checked, uniformed, and presents ID at your door. The person who opens your locks should be the most verifiable person you’ve ever hired. That’s our standard, not an upgrade.
Our Lock Installation & Rekey Services in Detroit
Smart Lock Installation
Smart lock installation in Detroit requires more than drilling a new hole. Most pre-war homes in 48209, 48210, and 48211 have mortise locksets set into solid wood doors two inches thick, with frames that have shifted through decades of freeze-thaw cycles. We retrofit Wi-Fi and Z-Wave smart locks from Schlage and Yale that integrate with existing mortise hardware where possible, or we replace the entire assembly with a properly seated modern equivalent. A typical smart lock installation in Detroit runs $280-$520, including frame adjustment if the door has settled. We always test the bolt throw after installation, because a smart lock that can’t fully extend into a racked frame is a smart lock that fails when you need it.

Keyless Entry
Keyless entry systems are popular with Detroit landlords and homeowners who manage multiple units or frequent tenant turnover. In the two-family flats common across 48208 and 48209, we install keypad deadbolts and lever sets that eliminate rekeying costs every time a lease turns over. Our keyless entry installations range from $190-$340 for a basic keypad to $420-$680 for a commercial-grade system with audit trails and timed access codes. We program everything before we leave, and we show you how to add or delete codes yourself. No service call required for a new tenant.

Keypad Lock
Keypad locks solve a specific Detroit problem: unknown key histories. On a DLBA resale or any home with extended vacancy, you don’t know who has a copy. A keypad lock removes that uncertainty entirely. We install weather-rated keypad deadbolts from Schlage and Kwikset that withstand Detroit’s temperature swings, and we back every installation with our written 90-Day Done Right Promise. Most keypad lock installations in Detroit fall between $220-$380. Seniors and veterans receive a permanent 5% discount.

Biometric Lock
Biometric locks, fingerprint readers specifically, are gaining traction in Detroit’s revitalized neighborhoods where homeowners are investing in long-term security upgrades. These units require precise alignment and clean power, and they’re not forgiving of racked door frames. We assess the frame condition first, repair or shim as needed, then install and enroll your fingerprints on-site. Biometric installation in Detroit typically runs $340-$580. We recommend Medeco or Yale units for their cold-weather reliability.

Electronic Lock
Electronic locks, the broader category covering key fobs, card readers, and Bluetooth-enabled units, serve Detroit’s small commercial buildings and multi-unit rentals. We wire and program standalone electronic strikes and maglocks for properties where traditional key control has broken down. Pricing starts at $260 for a basic electronic deadbolt and extends to $740 for a networked multi-door system.

Key Duplication
Key duplication in Detroit isn’t always straightforward. Mortise lock keys, Medeco restricted keys, and older bit-key patterns require specialized cutting equipment that hardware stores don’t stock. We cut on-site from code or by impression, and we can duplicate most residential keys while you wait. Standard key duplication runs $4-$12 per key; high-security Medeco or Mul-T-Lock duplicates range $18-$34. We also rekey existing locks to a single key, a common request after closing on a Detroit property.

Trusted Brands We Service in Detroit
We install and service Schlage, Kwikset, Medeco, and Yale locks daily in Detroit, and we stock parts for each in our service vehicles. That matters when you’re locked out at 11 p.m. in February and your cylinder has seized. We don’t have to order a replacement and return next week. We fix it tonight. For period-correct mortise hardware in Boston-Edison, West Village, or Jefferson-Chalmers restorations, we source Baldwin and Sargent through our Detroit supply partners with 24-48 hour turnaround. The right lock goes on the right door, not just what’s on the truck.
Common Lock Installation & Rekey Problems We See in Detroit Homes
- Freeze-thaw frame shift. Detroit’s winters regularly drop below 0°F, and the seasonal freeze-thaw cycle causes brick and wood-frame door assemblies in pre-war homes to shift enough to bind mortise bolts and deadlatch followers. We often need to adjust or shim the frame before a new lock will seat and throw properly.
- Vacancy damage from copper theft. Extended vacancy leaves strike plates pulled, door frames racked, and hardware corroded or stripped by scrappers. In ZIPs 48208 and 48209, we’ve replaced entire door jambs because the strike pocket was torn out by force. Full frame repair precedes lock installation in these cases.
- Iced and seized cylinders. Exterior pin-tumbler cylinders ice and seize frequently in January and February, driving a pronounced lockout spike. Our trucks carry de-icer and cylinder-specific extraction tools as standard equipment, not optional add-ons.
- DLBA resale unknown key histories. Detroit Land Bank Authority resales present a unique challenge: successive squatters and scrappers leave each exterior door fitted with a different, unkeyable combination. Re-pinning is impossible. Full mortise-lock replacement with period-correct hardware is the only viable approach, and familiarity with sourcing that hardware is a genuine competitive edge in these neighborhoods.

FAQs - Lock Installation & Rekey in Detroit
Successive squatters and scrappers install random, mismatched hardware with no key code documentation, making re-pinning impossible. On a typical DLBA resale, we find three different unkeyable brands on three exterior doors, none with matching keyways. Full mortise-lock replacement with period-correct hardware is the only way to give a new owner one key for the entire property. We responded to a DLBA resale on a craftsman foursquare in ZIP 48206 where scrappers had stripped the mortise lock from the front door and replaced it with a random Kwikset deadbolt. We sourced period-correct Baldwin mortise hardware and installed matching Schlage keypads on all three exterior doors, giving the new owner one key for the entire property. Call (877) 664-8139 if you’re closing on a Land Bank home, we’ll assess what you’re walking into.
Mortise locksets dominate the residential stock across 48204, 48206, 48208, 48209, and neighboring inner-city ZIPs. These are rectangular lock bodies set into a pocket in the door edge, with a separate knob and escutcheon, entirely different from the cylindrical bored-in locks standard in postwar construction. Most suburban locksmiths rarely encounter them. Our technicians carry the specialized mortise tools and know how to adjust for frames that have settled over a century. Call (877) 664-8139 for an exact quote, estimates are free.
Detroit’s winters regularly push below 0°F, and the seasonal freeze-thaw cycle causes brick and wood-frame door assemblies common in pre-war Detroit homes to shift enough to bind mortise bolts and deadlatch followers. Exterior pin-tumbler cylinders ice and seize frequently, driving a pronounced January-February lockout spike that demands locksmiths carry de-icer and cylinder-specific extraction tools as standard equipment. We account for this in every winter installation, testing bolt throw at multiple temperatures and ensuring weatherstripping won’t trap moisture that refreezes. Call (877) 664-8139 for an exact quote, estimates are free.
Yes, though it requires more than a standard retrofit kit. Most smart locks are designed for cylindrical bored-in doors, not the two-inch solid wood doors with mortise pockets common in Detroit’s 1910-1945 housing stock. We either adapt the smart lock to integrate with existing mortise hardware or replace the entire assembly with a properly seated modern equivalent, including frame adjustment if the door has shifted. A typical smart lock installation on a mortise door in Detroit runs $280-$520. Call (877) 664-8139 for an exact quote, estimates are free.
Each door was fitted by a different squatter, scrapper, or previous owner with whatever hardware was available, with no coordination between them. There’s no master key system, no common keyway, and often no documentation of who installed what. This is standard on Detroit Land Bank Authority resales, unique to Detroit at this scale, and it’s why we recommend a full assessment before closing. We can key all new hardware alike and install matching keypads or smart locks so you carry one key, not five. Call (877) 664-8139 for an exact quote, estimates are free.
