Precision Fitting for New Door Security Hardware
Installing a lock is a precise process that requires exact alignment and boring. A misaligned lock causes excessive wear on internal parts and weakens physical resistance to force.
The Process of Fresh Lock Fitting
A fresh lock installation involves drilling new holes in a door that has never had a lock, or expanding the existing boreholes to fit new hardware. (For auto security issues, see our car lockout services). This is common when adding a secondary deadbolt above an existing entry knob to improve home security. The alignment must be accurate down to a fraction of a millimeter.
We begin by using a specialized boring jig clamped to the door edge. This tool guides the hole saws, preventing splintering on wood doors or tearing on steel entry doors. We cut a 2-1/8 inch cross bore hole through the door face, and a 1-inch latch hole through the door edge. If these two cylinders do not meet at a perfect 90-degree angle, the latch latch bolt will bind, creating friction every time the latch is turned.
Once the holes are bored, we mortise the edge of the door so the latch plate sits flush. If the plate protrudes, it will scrape against the door frame, preventing the door from closing properly. We then chisel out a pocket in the door frame for the strike plate, reinforcing it with 3-inch screws that anchor deep into the structural wall studs behind the decorative wood trim.
Choosing the Right Hardware for Your Property
We install lock hardware across all security grades. For residential homes, we typically install Grade 2 deadbolts, which provide excellent resistance against physical attacks. For businesses, we install heavy-duty Grade 1 mortise locks and exit devices that withstand hundreds of thousands of cycles and resist heavy hammer blows.
We work with major brands such as Schlage, Kwikset, Baldwin, Yale, Medeco, and Mul-T-Lock. If you are interested in modern access options, we also install electronic keypad locks and smart locks that integrate with home networks. If you are experiencing lock issues with existing hardware, you can view our lock repair page to explore your servicing options.

Common Situations Requiring Lock Installation
Installing new locks is a critical step during property transitions, security upgrades, or building construction.
Moving to a New Home
When you purchase a new house, you cannot know who possesses copies of the old keys. Rather than rekeying worn-out, cheap hardware, many choose to install fresh locks throughout the house. This ensures your locks match aesthetically, operate with a single key, and provide modern resistance against lock bumping.
Upgrading to Deadbolts
Many older doors only have a locking doorknob. Locking doorknobs are vulnerable to simple bypass techniques like latch slipping with a plastic card. Installing a separate, heavy-duty deadbolt above the knob adds a sturdy steel bolt that extends a full inch into the reinforced door frame, increasing resistance to forced entry.
Smart Lock Integration
Transitioning to smart locks lets you manage access via phone apps, track who enters, and create temporary codes for guests or service workers. Fitting these locks requires careful alignment because electronic deadbolts rely on a small motor to throw the bolt. If there is any resistance due to misalignment, the motor will stall or drain the battery.
Commercial Hardware Upgrades
Businesses must comply with ADA accessibility standards and local building fire codes. We install lever handles, panic exit bars, and commercial mortise cylinders that meet these requirements. These systems ensure secure entry from the outside while allowing unhindered exit from the inside during an emergency.
Critical Factors in Lock Installation
Understanding door materials, lock grades, and correct installation methods promotes the durability of your hardware.
| Lock Grade | Standards & Testing | Common Applications | Security Level |
|---|---|---|---|
| Grade 1 (Commercial) | Tested for 1,000,000 cycles and heavy physical impacts. | Commercial buildings, schools, high-traffic entryways. | Highest physical security and durability. |
| Grade 2 (Heavy Residential) | Tested for 400,000 cycles and medium physical impacts. | Residential main entry doors, light commercial offices. | Excellent balance of cost and protection. |
| Grade 3 (Light Residential) | Tested for 200,000 cycles and basic security needs. | Interior doors, closets, laundry rooms. | Standard protection for low-risk entryways. |
Door Materials and Installation Techniques
The type of door material dictates the tools and techniques used during installation. For standard wood doors, we use sharp wood chisels to mortise the faceplate and strike plate recesses. The wood must be chiseled out carefully so the grain does not split. Splitting the wood around the latch pocket significantly weakens the door's strength against kicking.
For steel or fiberglass doors, the process is different. These doors feature a hollow core filled with insulating foam, reinforced with internal wood or steel blocks along the edges. Boring a new hole requires bi-metal hole saws and lubricating oil to prevent overheating the drill bits. We must add specialized spacer rings or metal reinforcement sleeves inside the door core to prevent the door faces from collapsing when the lock mounting bolts are tightened.
Strike Plate Reinforcement
A lock is only as strong as the frame it latch into. Most retail locks come with small strike plates and 3/4-inch screws that only penetrate the thin pine wood of the door jamb. During a break-in attempt, this wood splits professionally. We install heavy-duty, box-style strike plates secured with 3-inch hardened steel screws that pass through the jamb and bite directly into the heavy wall studs of the house frame. This reinforcement turns a weak point into a solid barrier.
Local Maryland Home Styles and Installation Challenges
The variety of housing styles in Maryland brings specific installation requirements.
Historic Properties and Custom Retrofitting
In older cities like Annapolis or historic sections of Baltimore, homes feature solid wood doors that are over a century old. These doors do not use standard modern prep dimensions. They often contain large pocket mortise locks that require custom carpentry to replace or upgrade. Installing modern deadbolts on these doors requires hand chiseling and custom-machined adapter plates to avoid damaging the historic value of the door.
We take pride in performing these retrofits cleanly, ensuring that we preserve the original woodwork while adding modern security locks that protect your family and property.
Smart Lock Range in Suburban Developments
In newer developments throughout Columbia, Ellicott City, and Bowie, homes feature modern steel-insulated or fiberglass doors. These structures are ideal for smart locks and electronic keypads. However, the alignment of the door must be perfect. If a door is exposed to direct sun, the heat can cause the fiberglass to bow slightly. We adjust the latches to ensure that even with minor seasonal warping, the electronic deadbolt operates without binding, preventing battery drain and motor failure.
Frequently Asked Questions About Lock Installation
Answers to common questions regarding new lock fitting, smart locks, and hardware selection.
What is a fresh lock installation?
A fresh lock installation refers to boring new holes in a door that has never had lock hardware installed, such as adding a new deadbolt above a standard locking doorknob. We use a precise boring jig to drill the cross bore and edge holes, chisel out the latch and strike plate pockets, and install the new lock assembly from scratch.
Can you install a smart lock on my existing door?
Yes. Most smart locks are built to fit standard prep holes (2-1/8 inch cross bore and 2-3/8 or 2-3/4 inch backset). We can retrofit smart locks onto your door, verifying that the lock chassis is aligned so that the motorized bolt moves into the strike plate without scraping or binding, which prevents battery drain. If you need other door adjustments, check our mortise lock repair services or review our services page.
What is the difference between Grade 1 and Grade 2 locks?
Grade 1 is the highest standard certified by ANSI/BHMA, designed for heavy commercial use (tested for 1 million cycles and high impact resistance). Grade 2 is a mid-tier standard for residential use or light commercial applications (tested for 400,000 cycles). Grade 3 is basic residential hardware (tested for 200,000 cycles).
How long does it take to drill and install a new deadbolt?
For a standard wood or metal door, a fresh deadbolt installation typically takes about 30 to 45 minutes. This includes clamping the boring guide, drilling the face and edge holes, chiseling the mortise pockets for the latch and strike plate, aligning the lock cylinder, and securing the strike plate with reinforced screws.
Is it necessary to reinforce the door frame when installing a new lock?
Yes. The strongest lock is useless if the wood frame surrounding the strike plate splits easily. We reinforce the installation by using heavy-duty strike plates and 3-inch steel screws that anchor deep into the wall framing studs behind the door jamb. This prevents the door jamb from splitting during a forced entry attempt.
