Why you'll love it

Loud alarm deters thieves

A built-in motion sensor activates a loud 10-second alarm whenever the lock is disturbed, drawing attention and scaring off potential theft.

All-weather durability

Waterproof construction keeps the lock reliable in rain or shine, so you can park with confidence in any conditions.

Easy push-to-lock operation

Simply push to lock and use the key to release—no complicated setup. An audible 5-second delay before arming gives you time to step away.

Low battery indicator

A low battery indicator alerts you when it's time for a replacement, and the included spanner makes battery access simple.
