Deadbolt Installation

A high-grade lock installed poorly is only marginally better than a cheap one installed well. Misaligned strike plates, shallow bolt throw, loose mortise pockets, and improper backset measurements are the four most common installation errors that leave a door vulnerable — even when the hardware itself is top-tier. Brands like Schlage and Kwikset manufacture excellent deadbolts, but their security ratings assume correct installation in a properly reinforced door frame. In Chicago's older housing stock — bungalows on the South Side, courtyard buildings in Uptown, coach houses in Bucktown — door frames are often original wood construction that needs reinforcement before a grade-1 deadbolt can perform at full potential.

This is why working with a skilled, insured locksmith matters. Our technicians don't just swap hardware; they evaluate the door, the frame, and the hinge side before recommending a lock. We use a damage-free approach wherever the door and frame allow, preserving finish and frame integrity — something that's especially important in buildings with historic woodwork or landlord-managed properties where you need to avoid unnecessary alterations.

Not every door accepts the same lock type, and choosing the wrong one is an expensive mistake. Cylindrical deadbolts — the standard single or double-cylinder format most residential doors use — work well in doors with a 2-1/8 inch bore. But in commercial settings, high-traffic entryways, and many Chicago multi-flat buildings with metal doors, a mortise lock is the stronger and more appropriate choice. A mortise lock fits into a pocket (the mortise) cut into the door edge, distributing load across a larger surface area and providing a more tamper-resistant connection between the lock body and the door itself.

Our commercial locksmith services specifically include mortise lock installation and replacement, which is a core part of what we do for Chicago businesses — from restaurant entries on Randolph Street to office suites in the Loop. For residential customers in two-flats and three-flats, mortise lock upgrades are a significant step up from the thin-bolt cylindrical locks that come standard on many older Chicago rental doors. We also handle jimmy proof deadbolt installation, which is particularly effective on outswing doors and apartment vestibule doors where a traditional deadbolt's bolt can be more easily attacked. Jimmy proof interlocking deadbolts connect the lock body directly to the strike, making it extremely difficult to pry the door open even with significant force.

Roy Chicago Locksmith handles the full range of lock installation and upgrade work across every property type. Our residential locksmith services cover single-family homes, condos, coach houses, and multi-unit buildings throughout Chicago neighborhoods — including rekeying existing locks when a deadbolt itself is still sound but keys are unaccounted for. For homeowners moving into a newly purchased property anywhere from Beverly to Edgewater, we recommend an immediate deadbolt inspection and rekey or replacement as a baseline security step, since you can never be certain how many copies of the previous owner's key are still out in the world.

On the commercial locksmith side, we work with retail storefronts, office buildings, warehouses, and multi-tenant commercial properties. Commercial-grade mortise lock installation, high-security cylinder upgrades, and panic hardware compatibility are all part of our service scope. We also provide emergency locksmith response when a lock is damaged, a break-in attempt has occurred, or a door simply won't secure properly — available around the clock because security problems don't follow business hours. Our automotive locksmith capability rounds out the picture for customers who need car lockout help or ignition work in the same service call. No matter the situation, our team arrives equipped to handle it, because a mobile locksmith's value is measured in what they can resolve on the first visit.

One of the most common questions we hear is: how much does a locksmith cost in Chicago, and how much should locksmiths charge for a job like this? The honest answer is that there is no single flat rate because the variables genuinely affect labor and materials. The factors that shape your final quote include the type of lock being installed (a basic cylindrical deadbolt costs less in parts and time than a commercial-grade mortise lock), whether the door needs frame reinforcement or a new bore, the time of day the work is requested, and travel distance to your location within the Chicago metro area. Emergency locksmith calls outside regular hours involve after-hours technician deployment, which is a real cost factor. Any parts — the lock hardware itself, strike plates, reinforcement kits — are itemized clearly.

What we never do is start work and then present a surprise number at the end. Before any installation begins, your technician confirms an exact price and you approve it. That's true whether it's a straightforward door knob lock swap on a Lincoln Square bungalow or a full mortise lock installation on a Fulton Market commercial entry at two in the morning. If you're asking what to do if you can't immediately cover a locksmith cost, the best step is to call us at (773) 289-0025 and describe the situation — we can explain exactly what the job involves and what the quote will reflect so you can make an informed decision. We're here 24/7 and we answer every call directly.
