Overview
What Makes the Doberman the Go-To Combo Cable Lock?
The OnGuard Doberman Combo Cable Lock delivers heavy-duty theft deterrence in a self-coiling, easy-to-carry format. The 12mm-diameter cable resists cutting attempts while the integrated 4-digit combination lock eliminates the need for keys entirely. At 6 feet of reach, it handles a wide range of locking scenarios whether you're looping through a wheel, frame, or rack.
The self-coiling design keeps the cable tidy and tangle-free on the bike or in a bag, so there's no fumbling at the trailhead or coffee stop. It's a solid secondary lock for pairing with a U-lock, or a standalone option for lower-risk environments and quick stops where convenience is the priority.

Good questions
Get to know OnGuard

There's more to OnGuard than this one product. Our OnGuard page has the full OnGuard lineup we carry and more about the brand.
Visit the OnGuard page →Do I need a key for the Doberman lock?
No. The Doberman uses an integrated 4-digit combination lock, so there are no keys to carry or lose.
Is the Doberman a good standalone lock for bike security?
It works well as a secondary lock or for low-risk quick stops. For higher-risk areas, pair it with a U-lock for maximum protection.
Can I reset the combination on the Doberman?
The Doberman uses a factory-set combination. For a user-resettable option, check out the OnGuard Terrier.
