The best smart locks with multiple access options don’t rely on a single way in — they layer fingerprint, face, palm, PIN, card and app access so every person and every situation is covered. Multiple access isn’t just a feature list; it’s what makes a smart lock genuinely convenient and reliable. This guide explains why multiple access matters and how to choose a lock that does it well.
A lock with only one way in is a lock waiting to leave you stuck outside. The best locks make sure that never happens, giving each person their preferred method and keeping a dependable fallback in reserve for the rare day everything else fails. Here’s how the main access methods work and how to weigh them.
Why multiple access matters
No single access method is perfect. Fingerprints fail with wet or injured fingers; faces can be hard to read in some conditions; phones run out of battery; codes are forgotten. The best smart locks with multiple access solve this by giving you alternatives, so there’s always a convenient way in. Multiple access is really about reliability and never being locked out — the most practical benefit a smart lock can offer.
Fingerprint access
Fingerprint is the fast, personal everyday method — nothing to carry or remember. A capacitive sensor reads dry, cold or slightly damp fingers far better than a cheap optical one, and AI improves recognition over time. It’s the method most households use most, and the foundation of a good multi-access lock. See our access-technologies guide for detail.
Face and palm recognition
Face recognition opens the door hands-free — ideal when you arrive carrying bags or a child — while palm recognition offers touch-free, hygienic entry. Both are advanced biometrics that the best smart locks offer alongside fingerprint. Covlor builds face and palm recognition across its lineup, so hands-free entry is standard rather than a premium extra.
PIN and OTP codes
A PIN keypad is the flexible method for guests, help and deliveries — you can issue temporary codes and revoke them. Anti-peep entry lets you pad your real code with random digits so onlookers can’t guess it. OTP (one-time password) access takes this further, letting you share a code that expires after one use or a set window — perfect for one-off visitors.
RFID card and tap access
An RFID or NFC card lets you tap to enter — simple for children and elderly relatives who find biometrics fiddly. Cards can be deactivated instantly if lost, keeping access secure. As one layer among several, cards round out a lock’s accessibility so everyone has a method that suits them.
App and remote access
App unlock adds remote control, alerts and access logs. On a Wi-Fi model, you can open the door from anywhere, issue digital keys, and see who entered. It’s less an everyday method than a powerful supplement — letting someone in while you’re out. Our Wi-Fi smart lock guide explains the remote side.
The mechanical key backup
Every serious lock keeps a concealed mechanical key for emergencies — the ultimate fallback you hope never to need but will be grateful for if batteries and electronics ever fail together. Combined with emergency USB-C power, it ensures the best smart locks with multiple access never leave you stranded.
How to choose a multi-access lock
Look for at least a fast biometric (fingerprint or face), a PIN for guests, a card option, app control if you want remote access, and a mechanical key backup — plus the fundamentals of a multi-bolt body, durable motor and emergency power. Covlor’s lineup — the CR-L108, CR-L99, CR-L88 and CR-L51 — offers face and palm recognition, fingerprint, PIN, card and app control, multi-bolt bodies, wide 40–120 mm door-thickness support, an all-metal gear motor and emergency USB-C power — a strong example of multiple access done well.

Matching access methods to each household member
The beauty of multiple access is that everyone in your home can use the method that suits them best. You might open the door with a quick fingerprint, your partner with face recognition while carrying groceries, a teenager with their own PIN, and a young child or elderly parent with a simple tap card. A guest gets a temporary code, and when you’re travelling you unlock remotely through the app. No one is forced into a method they find awkward, and no one is ever stuck outside because their preferred method failed. This is what separates a genuinely well-designed multi-access lock from one that merely lists features on a box: it quietly adapts to real people with different abilities and habits.
How multiple access improves security
Layered access isn’t only about convenience — it strengthens security too. With several methods available, you can keep your most private method (a stored fingerprint or face) for yourself while handing out easily revocable PINs and cards to others. If a code is compromised or a card is lost, you deactivate just that credential without affecting anyone else. Anti-peep PIN entry stops shoulder-surfers, anti-spoofing biometrics resist fakes, and wrong-attempt lockout deters guessing. Far from being a weak point, a well-implemented set of access methods lets you compartmentalise and control entry in ways a single key never could.
The bottom line
The best smart locks with multiple access options layer fingerprint, face, palm, PIN, card, app and a mechanical key so every person and situation is covered — and you’re never locked out. Multiple access is about reliability and convenience for the whole household. Choose a lock that layers these methods on a strong, well-supported body, and you get keyless entry that simply always works.
Frequently asked questions
What are the access methods on a smart lock?
The best smart locks offer fingerprint, face and palm recognition, a PIN keypad, OTP codes, an RFID/NFC card, app unlock and a concealed mechanical key — so every household member and situation has a convenient, reliable way in.
Why do smart locks have multiple access options?
Because no single method is perfect — fingerprints fail with wet fingers, phones run flat, codes are forgotten. Multiple access ensures there’s always a convenient way in, which is really about reliability and never being locked out.
Which smart lock has the most access options?
Look for a lock that layers face and palm recognition, fingerprint, PIN, OTP, card, app and a mechanical key. Covlor’s models include face and palm recognition as standard alongside the other methods, offering comprehensive multiple access.
Can I remove one access method if a code or card is lost?
Yes. With multiple access, each credential is independent — if a PIN is shared too widely or a card is lost, you deactivate just that one from the app without affecting anyone else’s fingerprint, face or code. This is one of the quiet security advantages of a multi-access lock.
