If you live in an older home near Golf Road or along the established neighborhoods off Barrington Road in Hoffman Estates, there is a good chance your front door holds a secret inside its edge — a cast-iron or brass mechanism tucked deep within the door itself, rather than bolted through it. That mechanism is a mortise lock, and millions of homeowners across the Chicago suburbs have one without ever realizing it. Whether you are trying to figure out why your locksmith quoted a different price than your neighbor, or you just want to understand what is actually keeping your family safe at night, knowing the difference between a mortise lock and a door knob lock is genuinely useful information.
This guide walks you through exactly how to tell which type of lock is on your door, why it matters for security and service, and what you should do when something goes wrong with either one. Our team at Hoffman Estates Locksmith works on both lock types every single day — on doors ranging from 1960s ranch homes to new-construction townhouses — and we want you to walk away from this article feeling informed, not confused.
## What Is a Mortise Lock — and Why Are They Everywhere in Older Hoffman Estates Homes?
A mortise lock is a lock set that is installed inside a deep, rectangular pocket (the "mortise") cut into the body of the door itself. Instead of simply drilling two holes through the door face like a modern cylindrical lock, a skilled carpenter or installer had to chisel out a cavity — sometimes four to six inches deep — to house the entire lock mechanism. The result is a robust, multi-component system that typically includes a latch bolt, a deadbolt, a keyhole, and often an interior thumbturn, all contained within a single metal case. When you see a door with a large, ornate faceplate running vertically along the door's edge and a separate keyhole below or above the knob, you are almost certainly looking at a mortise lock set.
Hoffman Estates was largely developed between the late 1950s and the 1980s, and many of the homes on streets like Bode Road, Hassell Road, and throughout the Higgins Corners area were built during a period when mortise locks were still the builder's standard choice. They were considered premium hardware — more secure and more durable than the cylindrical alternatives that eventually took over the market. Decades later, those same locks are still doing their job, which is a testament to their quality. The trade-off is that replacement parts, rekeying, and repairs require a locksmith with specific experience in mortise work, because the internal components — springs, cams, and levers — are more complex than anything found inside a standard door knob lock.
## Door Knob Lock vs. Mortise Lock: How to Tell the Difference in 60 Seconds
Stand at your front door and look at the edge of the door — the narrow strip of wood or steel that faces you when the door is open. On a door with a standard cylindrical door knob lock (or a knob lock paired with a separate deadbolt), you will see one or two small, round faceplates with latch bolts sticking out. The hardware is mostly on the face of the door, inserted through drilled holes, and the knob or lever handles are the most prominent feature. A door knob with lock and key in this style is the most common setup in homes built after the mid-1980s, and it is what most people picture when they think of residential door hardware.
On a door with a mortise lock, the edge of the door tells a very different story. You will see a tall, narrow metal plate — often three to five inches long — with both a latch and a deadbolt bolt visible side by side. Open the door and look at the face: instead of a simple knob backplate, there is usually a large, flat escutcheon (a decorative plate) that covers the entire lock body, and the keyhole may be a traditional oval shape rather than a modern key slot. If you see that tall faceplate on the door edge AND a large escutcheon on the face, you have a mortise lock. If you are unsure, our team is happy to walk you through it over the phone — call (224) 496-3191 any time, day or night.
## Security, Repairs, and Rekeying: Why the Lock Type Changes Everything
Understanding which lock is on your door directly affects what a locksmith does when you call. With a standard cylindrical door knob lock, rekeying is a relatively quick process — the cylinder is removed, the pins are changed, and new keys are cut. A mortise lock set requires a locksmith to remove the entire case, service or replace internal components, and sometimes source specific parts that are no longer in mass production. Older Hoffman Estates homes sometimes have mortise locks from manufacturers whose parts are no longer on store shelves, which means your locksmith needs hands-on experience sourcing compatible internals or retrofitting modern cylinders into legacy housings.
From a security standpoint, a properly maintained mortise lock is extremely difficult to compromise through normal attack methods, because the bolt engagement is deep and the lock body is reinforced by the door structure around it. However, age is the enemy of any mechanical system. Springs weaken, cams wear, and the cylinder itself can loosen — all issues our locksmiths diagnose and correct regularly. If you have noticed your key sticking, the latch not retracting cleanly, or the thumbturn feeling loose, those are early warning signs worth addressing before you end up locked out. Preventive service on a mortise lock is almost always simpler and less disruptive than an emergency call after a full failure. Speaking of which — if you are already locked out, do not attempt to force anything. Call us at (224) 496-3191 and we will dispatch a skilled technician to you promptly.
## What to Do When You Are Locked Out — Whether You Have a Knob Lock or a Mortise Lock
A lockout is stressful regardless of which type of lock is on your door, but the approach a qualified locksmith takes will differ based on the hardware. For a standard door knob with lock, there are non-destructive techniques that an experienced professional can use to open the door quickly. For a mortise lock, the process may take a few extra minutes because the internal mechanism requires more precise manipulation — but a locksmith with real mortise experience can still open it without damaging the door or the lock hardware in most cases. The goal is always to get you inside safely without destroying the hardware you paid for.
Before calling, it is worth doing a quick check: Is there a back door or window you left unlocked? Does a trusted neighbor or family member have a spare key? These are the right first steps. If none of those options pan out, that is exactly the scenario our mobile team handles around the clock. We serve Hoffman Estates and the surrounding communities 24 hours a day — including nights, weekends, and holidays — because lockouts do not wait for business hours. When you call, we will ask about your door type, verify your identity and ownership, and give you an exact up-front price before we begin any work. The final quote accounts for factors like the type of lock, parts required, time of day, and travel distance to your location — there are no surprise charges after the fact.

## Practical Advice: Maintaining Your Locks and Knowing When to Call a Professional
Regardless of whether your home has a mortise lock or a cylindrical door knob lock, routine maintenance extends the life of your hardware and prevents the kind of gradual failure that leads to a 2 a.m. lockout. For both lock types, spraying a graphite-based lubricant into the keyhole once or twice a year keeps the cylinder pins moving freely — avoid oil-based sprays, which attract dust and gum up the mechanism over time. For mortise locks specifically, check that the faceplate screws are tight and that the large escutcheon on the door face is secure; a loose escutcheon is often the first sign that internal components have shifted.
If your key has ever broken inside the lock, if the bolt does not extend or retract smoothly, or if the lock suddenly feels different than it used to, schedule a service call before the problem escalates. Our locksmiths work out of fully stocked mobile units, meaning we carry parts for a wide range of mortise lock sets and cylindrical locks on every call — no waiting for a parts order in most cases.

Frequently asked questions
Can a locksmith make a new key from a lock, even if the original key is completely lost?+
Yes — this is a standard locksmith service called "keying by code" or "impressioning," and it works for both mortise lock cylinders and standard door knob lock cylinders. A skilled locksmith disassembles the lock cylinder, reads the pin heights, and cuts a new key to match. For mortise locks on older Hoffman Estates homes, this is especially common because the original keys are long gone after decades of ownership changes. The process takes longer than a simple duplicate cut, and the price reflects the additional labor and any parts required — but our team confirms the exact cost with you before starting any work.
How much is the average locksmith charge, and what factors affect the price?+
There is no single flat rate for locksmith work because several variables affect every job differently. The type of lock involved — a standard door knob lock versus a complex mortise lock set — plays a significant role, as does whether any parts need to be replaced, what time of day the service is performed, and how far the technician needs to travel to reach your location. Emergency calls outside normal business hours typically involve a different rate than scheduled daytime appointments. What we can tell you is that we always provide an exact, confirmed price before any work begins, so you know precisely what to expect with no surprises on the final invoice.
How do I know if my door knob lock can be picked, and what should I do if I am locked out?+
Most standard door knob locks are less pick-resistant than a quality mortise lock or a high-security deadbolt, but the specifics depend on the brand and grade of the hardware. That said, we do not walk homeowners through lock-picking steps — attempting to open your own lock without the right tools can damage the mechanism, making the eventual repair more involved. If you are locked out, the right first steps are checking all other entry points (back door, garage, windows you may have left unlocked) and reaching out to anyone who holds a spare key. If none of that works, call a professional locksmith. Our team verifies your identity and ownership before any service, and we can open most residential locks non-destructively.
What does a locksmith do, and where does a locksmith work?+
A locksmith's work spans far more than just lockouts. Professional locksmiths install, repair, rekey, and replace lock hardware on residential doors, commercial properties, and vehicles. They cut keys, program transponder chips, service mortise lock sets, install high-security deadbolts, set up master key systems, and handle safe openings — among many other tasks. As for where we work: our Hoffman Estates Locksmith team is entirely mobile, meaning we come to you. We serve homes and businesses throughout Hoffman Estates and the surrounding northwest Chicago suburbs, operating 24 hours a day from fully equipped service vehicles. There is no shop you need to visit — we bring the tools and parts directly to your door or vehicle.
