Master Lock 8156DPS Keyed Cable Lock, U-Lock, Keyed Different, 5' (1.5m) Long, 3/4" (20mm) Diameter

Keyed different. Each 8156DPS ships on its own key, so if you buy several for a property or a crew, every lock carries a separate key and they will not interchange. For a maintenance crew that wants one key to open every cable on the truck, a keyed different lock is the wrong choice, and you would want to order a keyed alike cable lock instead.

Master Lock lists the 8156DPS as a residential grade lock. It suits homeowner and light property use, securing bikes, ladders, generators, gates, and gear. For a commercial application where the lock is the primary security on a site, a commercial rated padlock or a hardened shackle lock is the better fit, because a braided cable is a deterrent rather than an attack resistant barrier.

No. It is an auxiliary lock, a portable cable and U-lock that secures loose items and openings where you can pass a cable around something. It is not a door lock, it does not mount to a door, and it does nothing a deadbolt does. If you need to secure a door, you want a bored deadbolt or a mortise lock, not a cable lock.

It is key operated, not a combination. You get a keyed cylinder in the lock body, which is what most property managers prefer when they want control of who can open it rather than a code that gets passed around. There is no dial or resettable code on the 8156DPS.

The 8156DPS is described as a keyed cable lock, U-lock style, meaning the flexible 5 foot cable is secured by a rigid U shaped lock body rather than a small barrel lock. A straight cable lock with a barrel body is quicker to route but the body is the weak point. The U shaped body gives you a solid shackle to capture the cable ends and to clamp around a fixed post or rack when you want the cable and the U both doing work.

Yes, within its limits. Five feet of cable will wrap a gate post and hasp, or thread through the mesh of a storage cage and back, and the 3/4 inch cable diameter means it will not slip through a standard chain link diamond. Bear in mind it is a residential grade auxiliary lock, so treat it as a deterrent on a low risk opening rather than the security on a high value cage.
