Kryptonite Kryptolok Alarm Disc Lock 6mm Gry 6 of 10 004776

Kryptonite Kryptolok Alarm Disc Lock 6mm Grey New

Shield your e-bike from theft with a compact disc brake lock that combines mechanical security with an audible deterrent. The Kryptolok Alarm Disc Lock integrates a 120dB alarm into a rugged diecast body, designed to withstand weather and daily wear.

Why it stands out

Its 6mm locking pin fits standard rotor sizes up to 6.5mm, making it compatible with common discs. The alarm activates when tampered with, delivering a loud warning that draws attention and can deter opportunistic thieves. The electronics are weatherproof and fully enclosed, so performance remains reliable in rain or shine.

Battery life and keys

Expect up to about a year of battery life with the replaceable CR2 900mAh battery. Two stainless steel ergonomic keys ensure quick access and reduced wear. When a new battery is needed, it's simple to refresh without tools.

Ideal use cases

Perfect for city commutes, campus parking, or quick store runs where you need light, quick security. Lightweight and compact, it stays mounted on the bike without adding bulk, yet it’s tough enough to resist leverage attempts.

What you get

Actual product features include the Kryptonite brand pedigree, a 6mm pin, 120dB alarm, replaceable battery, and dual keys, all wrapped in a diecast, weatherproof shell for reliable day-to-day security.
