Keyless Entry Door Lock

The Meterk KS03 replaces a standard knob with a backlit keypad that accepts up to 20 user codes of four to ten digits plus a single-use code. Two mechanical keys are included for backup access. It fits most American standard doors 35 to 50 mm thick and suits front doors, bedrooms, garages, apartments, offices and rental units.

Anti-Peep Keypad and Auto-Lock

The illuminated keypad hides the real code among random digits so onlookers cannot guess the sequence. Auto-lock engages after 10 to 99 seconds by default, while passage mode disables it for unrestricted entry during gatherings. A thumb turn locks or unlocks from inside and a two-second press of any key locks from outside.

Grade 3 Security with IP55 Rating

Certified to BHMA/ANSI Grade 3, the lock withstands temperatures from -35 °F to 160 °F and resists water ingress to IP55. Battery life reaches 365 days with low-battery alerts. Wrong-code lockout and the one-time code add extra protection. Not suited for doors outside the 35-50 mm thickness range or for buyers needing Wi-Fi or gateway integration.

Questions about this item

How many user codes can the Meterk KS03 store before I need to delete old ones?

The lock supports up to 20 user codes of 4 to 10 digits each, plus a one-time code. When the limit is reached you must remove an existing code to add a new one.

What stops the keypad from accepting entries after repeated wrong attempts?

The anti-peep keypad enforces a wrong-code limit that temporarily disables entry after multiple failed tries, forcing a wait before another attempt.

How long will the four AA batteries last if the lock is used every day?

Up to 365 days of battery life is quoted, with a low-battery alert that warns you before the cells are exhausted.
