Apartment doors don’t always get a lot of attention, but they should.
Whether you’re settling into a new place or just curious about ways to improve home security, your front door is a smart place to start.
We’ll walk through 15 practical, renter-friendly ways to make your apartment door more secure – no drilling, no lease violations, no stress.
Key Notes
- Grade 1 deadbolts and reinforced strike plates provide maximum security impact.
- Portable locks and door jammers offer renter-friendly secondary protection options.
- Smart locks retrofit onto existing hardware without permanent modifications required.
- Layered security approach deters burglars better than single protection methods.
1. Upgrade to a Grade 1 Deadbolt
If your apartment only has a knob lock (or a deadbolt that’s loose, worn, or low quality), it’s time for an upgrade.
A Grade 1 deadbolt, like the Schlage B60 or Kwikset 660, provides the highest level of residential security.
Look for:
- A bolt that extends at least 1 inch into the door frame
- Hardened steel construction to resist sawing and prying
- Anti-pick and anti-bump features
NYC tip: You have the legal right to request a functioning deadbolt. If yours isn’t up to scratch, ask your landlord to replace it. If they won’t, you can often install one temporarily – just get written approval first.
2. Reinforce the Strike Plate with 3” Screws
A good deadbolt is only as strong as the frame it locks into.
Standard strike plates are usually held in with short screws, meaning one good kick can rip the whole thing out of the jamb.
Swap yours for a reinforced strike plate (look for steel models rated to withstand 800+ lbs of force), and use 3-inch screws that anchor into the wall stud, not just the trim.
This upgrade is inexpensive (~$10) but dramatically improves your door’s kick-in resistance.
3. Add a Secondary Lock (Portable or Swing Lock)
You know what’s better than one lock? Two.
A secondary lock like a swing bar, chain lock, or portable add-on creates an extra barrier – even if someone has a key or gets past the deadbolt.
Some of the best options for renters:
- Addalock Portable Lock: Installs in seconds on inward-swinging doors, no tools needed.
- Defender Security U 10827: High resistance to forced entry and only requires four small screws.
Perfect for extra nighttime security or peace of mind when you’re home alone.
4. Use a Door Security Bar or Jammer
A door security bar works by bracing against the floor and the doorknob, physically stopping the door from opening. It’s especially useful for older buildings with less sturdy locks.
Some bars can resist over 350 pounds of force, and you don’t need to drill anything to use them.
Portable door jammers, like the JIAN or SABRE models, wedge under the door and are great for both home and travel. Most models disengage quickly from the inside, so they won’t trap you in an emergency.
5. Install a Smart Lock (Renter-Compatible Models)
Think smart locks are just for homeowners? Think again.
Retrofit smart locks like the Wyze Lock Bolt, August Smart Lock, or eufy C210 are designed to work with your existing deadbolt hardware, so the landlord-facing part of the lock doesn’t change.
Benefits:
- Keyless entry via PIN, app, or fingerprint
- Remote lock/unlock and monitoring
- Temporary access codes for guests
- Tamper alerts and entry logs
And yes, most models let you keep using a physical key if needed.
6. Reinforce the Door Frame and Hinges
If your door is solid but the frame is flimsy, it’s still vulnerable. That’s why door frame reinforcement kits (like Door Armor or Prime-Line reinforcers) exist.
They come with:
- Metal strike shields
- Hinge reinforcements
- Extended screws
These upgrades distribute force across the frame instead of concentrating it on weak points like lock cutouts.
Pro tip: Also check your hinges. If your door swings outward, install hinge bolts or security studs so it can’t be removed – even if the pins are tampered with.
7. Fix Gaps with Weatherstripping or Door Seals
Large gaps between your door and frame aren’t just a draft problem; they’re a pry-bar invitation.
Weatherstripping kits or door insulation seals close those gaps, improving both security and energy efficiency.
Plus, in winter, they also keep your heating bill in check. Double win.
8. Install a Peephole or Digital Viewer
A peephole might seem basic, but it’s one of the most important security tools.
If your door doesn’t have one, or it’s the size of a pinhole, upgrade to a wide-angle (160°–180°) viewer. That way, you can clearly see who’s outside before opening up.
For an extra tech boost, try a digital peephole viewer. Some models even record short video clips when motion is detected.
9. Add a Video Doorbell (If Permitted)
Battery-powered video doorbells (like Ring, Eufy, or Blink) are renter-friendly and attach with adhesive or removable mounts.
They offer:
- Motion-triggered video
- Two-way audio
- Night vision
- Mobile notifications
They’re especially useful if you get frequent deliveries or if your building has no front desk security.
Check with your landlord first if the device will be visible in shared areas.
10. Don’t Overlook Sliding Doors
Live in a garden-level unit or an apartment with a balcony? Sliding glass doors are often the weakest link.
Secure them with:
- A metal bar or wooden dowel in the track
- Sliding door locks that prevent the panel from lifting
- Security film to reinforce the glass against breakage
These low-effort upgrades can make a huge difference.
11. Improve Lighting Around the Entry
Criminals don’t like being seen. So, if your apartment entrance is dark or tucked away, add a motion-activated light or plug-in hallway nightlight.
If you can’t add a fixture, battery-powered lights that attach with adhesive or magnets work well and don’t require wiring.
12. Secure Windows Near Your Door
If there’s a window within reach of your door’s lock or handle, reinforce it.
Add:
- Window locks or pin locks
- Security film (especially for basement or fire escape windows)
- Window alarms or sensors that alert you to breakage or forced opening
Burglars often use windows as a workaround to access door locks. Don’t give them that option.
13. Add Visible Deterrents (Alarms + Signage)
Even if you don’t have a full security system, you can add small wireless alarms that emit a loud siren if the door is opened unexpectedly.
Some renters also use window stickers or signs to suggest video surveillance or security monitoring.
It’s a psychological deterrent. Simple but surprisingly effective.
14. Talk to Your Landlord About Permanent Upgrades
Yes, you’re a renter, but that doesn’t mean you can’t ask for better security. Some landlords will approve upgrades like:
- Installing a solid-core or steel door
- Replacing old locks with Grade 1 deadbolts
- Adding peepholes, door chains, or viewer cameras
And if you cover the cost, they may be even more willing.
15. Use Layered Security for Best Results
The truth is: no single security upgrade is enough.
Burglars look for the easiest entry point. So your best defense is layering multiple measures:
- Grade 1 deadbolt
- Reinforced strike plate
- Portable lock or jammer
- Smart lock for access control
- Peephole or video doorbell
- Door and window sensors
- Good lighting and visibility
The more steps someone has to get through, the more likely they’ll move on.
How to Test If Your Apartment Door Is Secure
Before investing in reinforcements, it’s worth checking what you’re working with. A lot of renters assume their doors are “fine” because they lock and close.
But security isn’t just about having a lock, but about how the whole door system holds up under pressure.
Here’s how to test your door’s strength and spot potential vulnerabilities:
1. Push Test (AKA the Static Pressure Test)
What to do: Close your door and press firmly against it with your body weight, especially near the deadbolt area and along the handle side.
What you’re checking: Excessive flexing or movement (more than a few millimeters) could mean your door is hollow-core or your frame is loose. A solid door and tight frame should barely budge.
2. Gentle Impact Test (Dynamic Force Check)
What to do: Using the heel of your palm (or a soft padded object), give the area around the lock a few quick, controlled knocks.
What you’re checking: If anything rattles, shifts, or feels unstable (especially the lock or strike plate) that’s a red flag. Solid hardware should stay put and feel tight.
Important: Don’t go full action-movie here. Just enough force to simulate what might happen during a forced entry attempt.
3. Strike Plate & Screw Inspection
What to do: Open the door and look at the strike plate on the frame (the metal piece the deadbolt fits into). Unscrew one of the screws to see how long it is.
What you’re checking: If the screws are short (under 1 inch), they’re likely only going into the door trim, not the structural stud behind it. Replace them with 3” screws to seriously boost kick-in resistance.
4. Hinge Stability Test
What to do: Check your door hinges for any wobble, rust, or loose screws. Try gently lifting the door by the handle when it’s open. Does it sag or creak?
What you’re checking: Loose hinges weaken the door’s entire structure. If your door swings outward, check if the hinge pins can be popped out from the outside (not great). Add hinge bolts or security studs if so.
5. Gap and Alignment Assessment
What to do: Close the door and check for visible gaps between the door and frame, especially along the sides and bottom.
What you’re checking: Big gaps mean easier prying for intruders, and worse insulation. Weatherstripping can help seal small gaps, but if the door is warped or misaligned, it may need professional adjustment or reinforcement.
6. Lock Function & Resistance
What to do: Lock and unlock your deadbolt several times. Does it turn smoothly? Does it catch, wiggle, or feel too loose?
What you’re checking: A high-quality lock should feel smooth and firm – not sticky or flimsy. If it’s loose in the door or doesn’t extend fully into the frame, it may not hold up under pressure.
7. Can It Be Lifted or Pried?
What to do: For sliding doors, try lifting the door gently. If it moves upward or feels like it could be popped off its track, that’s a vulnerability. For swinging doors, check if a crowbar could fit into any visible gaps.
What you’re checking: A well-fitted door shouldn’t have that kind of play. Use anti-lift devices for sliding doors and reinforce swing doors with better frame anchoring and seals.
What These Tests Tell You
Think of these tests as a stress check – not a panic trigger.
If your door passes most of them, a few minor upgrades (like a reinforced strike plate or longer screws) can go a long way.
If it fails more than a couple, it might be time to speak with your landlord about a replacement or upgrade.

Frequently Asked Questions
Can I install a chain lock in a rental apartment?
It depends on your lease. Chain locks usually require drilling into the door or frame, so it’s best to get written permission from your landlord first or opt for a no-drill alternative like a portable lock.
Do landlords have to change the locks between tenants?
Not always, but it’s worth asking. Some states require it by law, while others don’t. If you’re unsure, request a lock change or rekeying when you move in for peace of mind.
Is renter’s insurance affected by door security?
Yes. Some insurance providers offer discounts for enhanced security features like deadbolts or monitored smart locks. Check with your provider to see if upgrades could lower your premium.
Can I hire a locksmith without going through my landlord?
For emergencies, yes, but for non-urgent upgrades, always check your lease first. Unauthorized changes could violate your agreement or affect your security deposit.
