Fingerprint vs Keypad vs WiFi Smart Lock: Which Type Is Right for You in 2026?
There Are Three Types of Smart Locks. Most People Buy the Wrong One.
Walk into any home improvement store — or scroll through any online retailer — and you'll find smart locks organized by price, not by how they actually work. That's a problem, because the type of smart lock matters far more than the brand name on the box.
A fingerprint lock and a Wi-Fi lock are fundamentally different products. They solve different problems. They fail in different ways. And they're right for different people.
We reviewed the three main types of smart locks available in 2026 — fingerprint/biometric, keypad/PIN, and Wi-Fi connected — and broke down exactly who each one is for. By the end of this guide, you'll know which type fits your life before you spend a dollar.
The Three Types of Smart Locks: A Quick Overview
| Type | How You Unlock | Remote Access | Best For |
|---|---|---|---|
| Fingerprint / Biometric | Touch sensor reads your fingerprint | Limited (Bluetooth) | Speed, convenience, no codes to remember |
| Keypad / PIN | Enter a numeric code | Limited (Bluetooth) | Simplicity, multiple users, no phone needed |
| Wi-Fi Connected | App, keypad, fingerprint, or voice | ✅ Full remote access | Remote workers, Airbnb hosts, full smart home |
Most modern smart locks combine two or three of these — a fingerprint lock with a keypad backup, or a Wi-Fi lock with fingerprint and keypad. The key question isn't which feature you want — it's which connectivity type fits your actual use case.
Type 1: Fingerprint Smart Locks
How They Work
A capacitive or optical sensor reads the unique ridge patterns of your fingerprint and matches it against stored templates. Modern fingerprint sensors can read a print in under 0.5 seconds — faster than any keypad or app. Most fingerprint locks store 50–200 fingerprint templates and include a keypad backup.
The Real Advantages
- Speed: Fastest authentication method available. Touch and go — no code to remember, no phone to unlock.
- No keys to lose: Your fingerprint is always with you.
- Multiple users: Enroll family members' fingerprints individually.
- No phone dependency: Works even when your phone is dead or out of range.
The Real Limitations
- Wet or dirty hands: Sensors can struggle with wet, dirty, or very dry skin.
- Limited remote access: Most connect via Bluetooth only — you need to be nearby to use the app.
- Guest access complexity: Guests need to be physically present to enroll their fingerprint.
Who It's For
Fingerprint locks are ideal for households where the same 2–5 people need regular access and speed is the priority. Families with kids, elderly parents who struggle with keypads, or anyone who hates fumbling for keys or phones.
Type 2: Keypad / PIN Smart Locks
How They Work
You enter a numeric PIN on a physical keypad — typically 4–8 digits — to unlock. Most keypad locks support multiple codes (20–150+), allowing different codes for different people. Some support one-time codes or scheduled codes that expire automatically.
The Real Advantages
- Universal access: Anyone can use a keypad — no smartphone, no fingerprint enrollment required.
- Easy guest access: Share a code verbally or by text.
- High code capacity: Models supporting 100–150 codes are ideal for property managers.
- Works in all conditions: Rain, gloves, dirty hands — a keypad works when a fingerprint sensor might not.
The Real Limitations
- Code sharing risk: Codes can be shared without your knowledge.
- Code memorization: You need to remember the code.
- Wear patterns: Frequently used keys can show wear, potentially revealing your code.
Who It's For
Keypad locks are ideal for anyone who needs to give access to multiple people without enrolling fingerprints — dog walkers, housekeepers, contractors, family members who visit occasionally.
Type 3: Wi-Fi Smart Locks
How They Work
Wi-Fi locks connect directly to your home network, enabling full remote access via a smartphone app from anywhere in the world. They typically combine Wi-Fi connectivity with keypad and/or fingerprint authentication.
The Real Advantages
- True remote access: Lock and unlock from anywhere — at work, traveling, or across the country.
- Real-time notifications: Get an alert the moment your door is locked or unlocked.
- Remote guest access: Create and share access codes remotely, without being home.
- Full access log: See a timestamped record of every entry and exit.
- Smart home integration: Trigger automations — turn on lights when you unlock, lock automatically at bedtime.
The Real Limitations
- Wi-Fi dependency: Remote features require your home Wi-Fi to be online.
- Battery drain: Wi-Fi connectivity uses more power than Bluetooth.
- Digital attack surface: More connectivity means more potential vulnerabilities — mitigated by AES encryption on reputable brands.
Who It's For
Wi-Fi locks are ideal for remote workers, frequent travelers, Airbnb hosts, and anyone building a full smart home system.

Common Mistakes When Choosing a Lock Type
- Buying a fingerprint lock when you need remote access. Fingerprint locks are fast locally — but if you need to let someone in while you're away, you need Wi-Fi.
- Buying a Wi-Fi lock when you just need keyless entry. If you never need remote access, a simpler keypad or fingerprint lock has better battery life.
- Ignoring the keypad backup on a fingerprint lock. Wet hands, gloves, or sensor issues happen. Always have a PIN backup.
- Assuming all Wi-Fi locks need a hub. Many modern Wi-Fi locks have built-in Wi-Fi. Check the specs.
- Choosing based on price alone. The cheapest option often skips ANSI Grade 1 certification. Always verify the security rating.

Frequently Asked Questions
Can I get a lock with both fingerprint and Wi-Fi?
Yes — and that's the best combination for most people. The DESLOC B200 WiFi includes both fingerprint and Wi-Fi connectivity, giving you the fastest local entry plus full remote access.
Do fingerprint locks work with gloves?
No — fingerprint sensors require direct skin contact. Make sure your lock has a reliable keypad backup. All our recommended fingerprint locks include keypad access.
How secure is a Wi-Fi smart lock compared to a keypad?
Both are secure when properly configured. Wi-Fi locks use AES encryption to mitigate digital risk. Use a 6–8 digit code and change it periodically for keypad locks.
Will a Wi-Fi lock drain my batteries faster?
Yes — Wi-Fi uses more power than Bluetooth. However, modern Wi-Fi locks like the DESLOC B200 are optimized for battery efficiency and still achieve 12-month battery life under normal use.
Do I need a hub for a Wi-Fi smart lock?
Not for our recommended models. The DESLOC B200 WiFi has built-in Wi-Fi and connects directly to your home network without a separate hub.
What's the most reliable type of smart lock?
Keypad locks are the most mechanically reliable — fewer components, no sensor to malfunction, works in all weather. For overall reliability including remote features, Wi-Fi locks from reputable brands are excellent.
