Heavy-Duty Jimmy-Proof Deadlock

The Yale 197 is a brass jimmy-proof deadlock with a thumbturn, designed for surface mounting on residential doors. It operates as a single-cylinder deadbolt with a Yale Y1 keyway and five pins, supplied with two keys and two hardened steel inserts. The lock fits door thicknesses from 1-3/8 in to 2-1/4 in with a 2 3/8 in backset.

Suitable For Surface-Mount Security

This deadlock suits doors where a mortice pocket cannot be cut, such as metal-clad or thin timber doors, and the thumbturn allows keyless locking from inside. It is not for buyers who need a mortice deadlock, a double-cylinder function for glass-adjacent doors, or a lock certified to a specific fire or insurance standard.

Yale Y1 Keyway With Five Pins

The cylinder uses the Yale Y1 keyway with five pins and is keyed different, so each lock opens only with its own keys. If your project requires keyed-alike sets, a master-keyed system, or a different keyway to match existing hardware, this cylinder will not meet that requirement.

Questions about this item

Which version of the Yale 197 Jimmproof Deadlock should I choose for a standard residential door?

The Yale 197 is a single-cylinder Jimmproof deadlock with thumbturn, designed for doors 1-3/8 in to 2-1/4 in thick with a 2 3/8 in backset. It includes a brass-plated finish, two keys and two hardened steel inserts.

How does the heavy-duty security rating translate to real-world protection?

The heavy-duty rating reflects a solid brass cylinder with five-pin Yale Y1 keyway and two hardened steel inserts that resist drilling and forced entry, while the single-cylinder thumbturn allows quick exit from inside.

What does the rim-lock interface mean for installation and compatibility?

This rim-mounted lock installs on the door surface rather than requiring a mortise pocket, so it fits most wood or metal doors within the stated thickness range without special tools.
