Types Explained
Door Knobs & Privacy Hardware
Interior knobs and levers, including privacy versions with a simple twist or push-button lock for bedrooms and bathrooms — not a security deadbolt.
- Easy DIY installation, usually under 30 minutes
- Wide style and finish selection to match existing hardware
- Privacy knobs aren't a security lock — most can be opened from outside with a small tool in an emergency
Best for: Interior bedroom and bathroom doors needing privacy, not security
Example: Copper Creek Colonial Privacy Knob
Deadbolts & Keypad Locks
The primary security lock on exterior doors, ranging from traditional key deadbolts to keypad models that unlock with a code instead of a key.
- The main line of defense on an exterior door
- Keypad models eliminate the need to carry or hide a physical key
- Graded deadbolts cost significantly more than interior hardware
- Keypad models need battery replacement
Best for: Exterior entry doors where security is the primary concern
Example: Schlage Camelot Keypad Deadbolt
Portable & Travel Door Locks
Compact, tool-free locks that add a layer of security to a door without any permanent installation or drilling.
- No installation, ideal for renters or hotel rooms
- Packs small for travel
- Supplements a door's existing lock rather than replacing it
- Not a substitute for a proper deadbolt on a primary residence
Best for: Travelers, renters, or anyone needing extra security without modifying the door
Example: Addalock Original Portable Lock
Security Bars
A freestanding bar or brace that wedges against the door and floor, adding resistance against forced entry.
- No installation required
- Portable between doors or residences
- Adds bulk that must be set up and removed each use
- Not effective on doors that swing outward
Best for: Renters or apartment dwellers wanting extra force-resistance without modifying the door
Example: SECURITYMAN 3-in-1 Door Security Bar
What Actually Matters
| Factor | Importance | Best brand |
|---|---|---|
ANSI/BHMA Grade rating (deadbolts) Grade 1 is the highest residential security rating; Grade 2 is standard-builder grade A deadbolt without a stated grade rating is worth asking about before buying for a primary entry door. | Must-have | Schlage publishes ANSI/BHMA grade ratings on its deadbolt line |
Backset and door thickness compatibility Standard doors use a 2-3/8 inch or 2-3/4 inch backset — measure before ordering a knob or deadbolt A mismatched backset is the most common reason DIY hardware installs fail on the first try. | Nice-to-have | — |
Keypad battery life and mechanical key backup Choose a keypad deadbolt with a physical key override in case the batteries die A keypad-only lock with no mechanical backup can leave you locked out if the battery dies at the wrong time. | Must-have | Schlage's Camelot keypad includes a physical key backup |
Finish durability (matte vs. polished) Matte and brushed finishes show fingerprints and wear less than polished brass or chrome over years of use. | Nice-to-have | — |
'Bank-vault' or 'unbreakable' security bar claims No consumer door bar is 'unbreakable' — it adds resistance and time, which is genuinely useful, but the marketing language overstates it. | Marketing BS | — |
'Military-grade' portable lock claims There's no regulated 'military-grade' consumer lock standard — treat it as marketing language, not a certification. | Marketing BS | — |
Budget Tiers & Top Picks
What to buy at each price point — and exactly where spending more stops paying off.
Everyday Hardware
$9 – $11Copper Creek Colonial Privacy Knob (Tuscan Bronze)
Stop paying more: At this price, you get a well-reviewed privacy knob — spending more here mostly buys finish variety, not more security.
When to upgrade: Need real security, not just privacy? Step up to a portable lock or deadbolt tier.
Supplemental Security
$24 – $35Addalock Original Portable Lock
Stop paying more: This tier covers tool-free supplemental security — it adds a layer of protection but doesn't replace a proper deadbolt.
When to upgrade: Securing a primary residence's main entry door? Move to the deadbolt tier for a permanent, graded lock.
Deadbolt / Keypad Lock
$100 and upSchlage Camelot Keypad Deadbolt
Stop paying more: A graded keypad deadbolt at this price is the ceiling most homes need — going pricier mostly buys smart-home connectivity, not more physical security.
When to upgrade: There isn't a meaningful step up here for most homes — connected smart locks with app control are a different category with their own tradeoffs.
Common Mistakes to Avoid
Installing a privacy knob on an exterior entry door expecting real security
Privacy knobs are designed for interior bedroom and bathroom doors — most can be opened from outside with a small tool, unlike a graded deadbolt.
Cost of getting it wrong: A false sense of security on the door that actually needs the strongest lock in the house
Not measuring backset before ordering hardware
Standard doors use a 2-3/8 inch or 2-3/4 inch backset — ordering the wrong size means the new hardware won't align with the existing door prep.
Cost of getting it wrong: A return and reorder, plus a door without working hardware in the meantime
Relying on a portable lock or security bar as your only entry-door security
These products supplement an existing lock — they aren't rated replacements for a graded deadbolt on a primary residence's main entry door.
Cost of getting it wrong: Weaker security than expected on the door that matters most
Buying a keypad deadbolt with no mechanical key backup
If the batteries die and there's no physical key override, you can be locked out of your own home until you find a way in.
Cost of getting it wrong: An unplanned lockout and possible locksmith call

Frequently Asked Questions
How much should I spend on door hardware or locks?
Interior privacy knobs run $9-$11. Portable locks and security bars run $24-$35. A graded keypad deadbolt for an exterior entry door runs around $100-$110.
What should I avoid when buying door hardware or locks?
Avoid putting a privacy knob on an exterior entry door expecting real security, and don't rely on a portable lock or security bar as your only lock on a primary residence's main door.
What's the difference between a privacy knob and a deadbolt?
A privacy knob has a simple twist or push-button lock meant for interior doors; a deadbolt is a graded security lock designed for exterior entry doors.
Do keypad deadbolts need a physical key too?
Look for one that includes a mechanical key override — without it, a dead battery can lock you out of your own home.
Are portable door locks a good substitute for a deadbolt?
No — they add a supplemental layer of security for renters or travel, but they aren't rated replacements for a graded deadbolt on a primary entry door.
What backset size do I need for a new doorknob or deadbolt?
Measure your existing hardware first — most residential doors use a 2-3/8 inch or 2-3/4 inch backset, and ordering the wrong size means it won't align with the door prep.
