Keypad door locks offer a simple way to replace traditional keys with PIN-based access, while some models add biometric entry for even faster unlocking.
The MSR X6 Biometric Smart Door Lock and iulock IU-30 Keypad Smart Door Lock take different approaches. While MSR focuses on fingerprint convenience and automatic locking, iulock mainly emphasises high code capacity, long battery life, and weather resistance.
