What We Offer
Wide-Angle Optical Viewers
Installation of 160° to 200° wide-angle brass lenses that eliminate blind spots and allow you to see anyone standing to the side or crouching low.
Digital Peephole Cameras
Upgrade to LCD digital viewers that display a clear, bright picture of your porch on a screen inside your home, perfect for the visually impaired or children.
Fire-Rated Door Compliance
We utilize UL-listed, fire-rated optical viewers (with glass lenses, not plastic) to maintain your apartment or condo door's strict fire code rating.
Ring Peephole Cams
Professional installation of smart peephole cameras that connect to Wi-Fi, providing motion alerts and two-way audio directly to your smartphone.
Do Not Open the Door to a Stranger
Visual verification is the absolute foundation of home security. The most sophisticated deadbolt in the world is useless if you voluntarily unlock and open the door because you feel pressured to answer a knock.
In Washington DC, where package deliveries, food couriers, and door-to-door solicitors are a daily occurrence, a door viewer is not a luxury, it is a necessity. DC Local Locksmith provides fast, clean, and exact peephole installation for residential doors across the district.
Optical Peepholes: Simple & Fail-Proof
Traditional optical viewers rely purely on optics and require zero power. However, not all peepholes are created equal.
If your home has an old viewer, it likely utilizes a cheap plastic lens that has clouded over time, offering a narrow 90-degree field of view. A criminal can easily avoid detection by standing flat against the wall next to your door.
We install massive upgrades:
- 200-Degree Ultra-Wide Lenses: These high-grade glass lenses distort the image intentionally to suck in the entire peripheral view of your porch, floor to ceiling, wall to wall.
- Privacy Covers: A built-in interior flap prevents light from escaping (which tells a knocker you are home) and prevents reverse-viewing tools from being used.
- Fire-Rated Models: For multi-unit buildings, altering a fire door can void its rating. We install heavy brass, UL-listed door viewers with glass lenses that will not melt in a fire, keeping your HOA and fire marshal happy.
Digital Door Viewers
For older adults, individuals with poor eyesight, or small children who cannot reach a standard peephole, optical viewers can be difficult to use.
Digital door viewers replace the interior optical lens with a crisp, bright LCD screen mounted directly to the door.
- Easy Viewing: No more squinting with one eye against a cold metal dot. Simply press a button, and the screen acts like a digital window.
- Recording Capability: Many digital models automatically snap a photo onto a MicroSD card whenever the doorbell is pressed or motion is detected, giving you a log of visitors while you were away.
- Damage-Free Smart Upgrades: Platforms like the Ring Peephole Cam slide directly into the exact same barrel hole as a standard 14mm optical viewer. This means you can get a smart doorbell camera on an apartment door without drilling new framing holes or running exterior wires.
Precision Installation Matters
Drilling through a thick exterior door is permanent. Drilling at an angle means the viewer will not sit flush. A dull bit blows out the wood veneer on the far side, leaving a hole that costs far more than the peephole to repair.
Our locksmiths use self-centering jigs, pilot holes, and specialized hole saws to bore cleanly through wood, steel, and fiberglass, producing a factory-finish result. Contact DC Local Locksmith today to schedule an installation.
Hardware Comparison
Choosing the Right Deadbolt
| Feature | Single Cylinder | Double Cylinder |
|---|---|---|
| Key requirement | Key outside, thumb-turn inside | Key required from both sides |
| DC fire code | Required on most primary exits | Permitted on glass-panel doors only |
| Best for | Standard exterior doors, front and back | Doors adjacent to glass panels or sidelights |
| Emergency egress | No key needed from inside | Key must be kept accessible near door |
DC Local Locksmith recommends single-cylinder on all primary exits per DC fire code.

Door Viewer Installation in Washington DC FAQs
Can a burglar look through my peephole from the outside?
With a standard builder-grade peephole, yes, someone can use a 'reverse peephole viewer' tool to look inside your home. We install privacy covers (small swinging metal plates) on the interior of every optical peephole to block the lens until you are ready to use it.
I live in a condo. Can you drill a hole in my metal door?
Yes. We routinely drill through solid wood, fiberglass, and hollow-metal fire doors. We use specialized, progressive drill bits to ensure a clean, splinter-free hole that fits the viewer barrel precisely.
Are digital peepholes difficult to use?
Not at all. The basic models operate with a single button press. When someone knocks, you press the button, and the screen lights up for 15 seconds to show you the camera feed. They run on standard batteries and require zero wiring.
Are you licensed and insured for residential work in DC?
Yes. DC Local Locksmith holds a current DC and MD license, is fully bonded, and carries general liability insurance. Documentation is available on request.
Do you offer after-hours service for home lockouts?
Yes. Our dispatch line is staffed 24 hours a day, 7 days a week, including holidays. Quoted before dispatch.
Which lock brands do you install and service?
We install and service Schlage, Yale, Kwikset, Medeco, Mul-T-Lock, and most ANSI-rated residential hardware. We can supply hardware or install what you provide.
Should I rekey or replace my locks after moving into a new home?
Rekeying is the faster option when the hardware is in good condition and serves most change-of-occupancy needs. Replacement is warranted when hardware is worn, damaged, or below ANSI Grade 1 standard. We confirm which path fits your hardware during the quote.
Can you cut additional keys on-site?
Yes. We carry key blanks for most residential cylinders and can cut copies at the time of service.
What is ANSI Grade 1, and do I need it for my exterior doors?
ANSI Grade 1 is the highest residential security rating, tested for 250,000 cycles, 6 attempts at 75-pound force, and pick/drill resistance. We recommend Grade 1 on all exterior doors and Grade 2 minimum on interior doors.
What is your protocol for eviction-related lock changes?
We require a copy of the court order before performing an eviction lock change. We do not perform lock changes on occupied residential units without legal authorization.
