Fingerprint and keypad locks both let you leave your keys at home. The difference is how you get in: a code anyone can be told, or a finger only you have. Most fingerprint locks also include a keypad, so the real question is whether biometrics are worth paying for.
Side by side
| Fingerprint | Keypad only | |
|---|---|---|
| Speed | About a second, one touch | Typing a 4–8 digit code |
| Sharing access | Enroll each person in person | Give out a code; easy for guests and services |
| Code leaks | Nothing to overhear or share | Codes get shared; worn buttons can hint at digits |
| Kids and elderly | No code to remember; some people's fingerprints read poorly | Needs remembering the code |
| Weather | Wet, cold or dirty fingers can fail | Works with gloves on some models |
| Price | Higher | Lower |
When fingerprint is worth it
- Busy households where people come and go with full hands.
- Kids who would forget or share a code.
- You want to know exactly who unlocked the door (with app-connected models).
When a keypad is enough
- Rentals and guest access: you can change codes between visitors.
- Exposed entrances in rain or snow.
- Tight budget: a keypad deadbolt costs less for the same lock hardware.
Best of both: most fingerprint locks also accept a code, an app or a key. That backup matters more than the sensor; never buy one without a second way in.
Security notes
The electronics are rarely the weak point. Check the mechanical lock: a solid bolt, a reinforced strike plate with long screws into the frame, and an ANSI/BHMA grade rating if listed. Choose a model with a weatherproof rating (IP65 or similar) for outdoor-facing doors.

FAQ
Are fingerprint door locks more secure than keypad locks?
They avoid shared or overheard codes, but overall security depends mostly on the mechanical bolt and strike plate. Choose a solid deadbolt with a backup entry method.
Do fingerprint locks work in the rain or cold?
Wet, very cold or dirty fingers can fail to read. That is why most fingerprint locks also offer a keypad, app or key backup.
