One person taps an Apple Watch. Another touches the fingerprint sensor. A guest needs a code. When you choose a smart lock, the best unlock method is the one that fits the people who actually use your door—not just the feature that sounds most advanced.
Here is how Apple Home Key, fingerprint and keypad entry differ in daily life, and how those choices map to LNDU locks.
Start with your household's routine
Before comparing products, write down who needs access and what each person is comfortable using. A phone or watch may be effortless for one resident, while a keypad may be simpler for a child, a visitor or someone who does not use Apple devices. Also decide what everyone will do if their preferred method is unavailable.
- Choose Home Key if tapping an iPhone or Apple Watch is already part of your routine.
- Choose fingerprint if regular users want a quick, phone-free way in.
- Choose a keypad if different people need access without enrolling a fingerprint or carrying a device.
These are not mutually exclusive. A lock with more than one entry method can let each person use the option that works for them.
Apple Home Key: tap with an iPhone or Apple Watch
With a supported lock and a compatible Apple device, Home Key lets you hold an iPhone or Apple Watch near the lock to unlock. You do not have to open the lock's app or type a code at the door. Apple explains the setup and device requirements in its Home Key guide.
Home Key is a specific tap-to-unlock feature. It is not the same as a lock merely appearing in the Apple Home app, and it is not the same as remote unlocking. If Home Key is your priority, confirm that the exact model supports it.
Among LNDU's current smart locks, the HK01W offers Apple Home Key. It also provides fingerprint, passcode and physical-key options, so a household member without an iPhone does not have to use Home Key.
Fingerprint: convenient for regular users
Fingerprint entry is useful when you would rather touch the lock than reach for a phone or remember a code. It suits people who come and go frequently, but each regular user must first enroll a fingerprint. Keep another supported method available in case a finger cannot be read—for example, when it is wet, dirty or covered by a glove.
LNDU's HK01W, T225 and WL01 offer fingerprint access. The DL500 can provide fingerprint entry through its compatible external keypad. For a retrofit setup, confirm the package contents and compatibility before buying.
Keypad: flexible for family and guests
A keypad is often the easiest method to share across a mixed-device household. Someone can use a code without owning an iPhone, wearing a watch or enrolling a fingerprint. It is also useful when you need to give a trusted visitor access.
Codes still need some care. Choose codes that are not easy to guess, keep administrator credentials private and remove access that is no longer needed. If you specifically need timed or one-time guest codes, check the feature list and instructions for the exact model; code-management options are not identical across locks.
For straightforward local keypad entry, the D180 uses passcodes and a physical-key backup. Its documented setup does not require an app or Bluetooth pairing. HK01W, T225 and WL01 also support codes, while the DL500 uses a compatible external keypad for code entry.
What works for different households?
Mostly Apple devices
If residents already carry iPhones or wear Apple Watches, Home Key may be the most natural everyday method. The HK01W also leaves fingerprint and code entry available for people who prefer them.
Several regular users with different devices
Fingerprint plus keypad is a practical combination: enroll the people who use the door every day, then keep codes for those who do not want or cannot use fingerprint entry. Depending on your door hardware, compare HK01W, T225 and WL01.
Occasional visitors or a simple code-first setup
Start with keypad access and think about how you will add, change and remove codes. If you do not need an app, the D180 may be worth considering. If remote code management matters, compare the connected models and their specific instructions rather than assuming every keypad works the same way.
Check the door before choosing the feature
An unlock method cannot make an incompatible lock fit. Before ordering, identify your existing lock type and measure door thickness, backset and available mounting space. Make sure the door closes and the bolt moves smoothly. A retrofit model such as DL500 has different installation considerations from a replacement deadbolt or an integrated handle lock.
Use LNDU's door-fit checklist and model comparison to narrow down the hardware. Then choose the entry methods that make sense for the people coming through your door each day—and confirm the backup method before you rely on the lock.
