			The '''917''' is a [[Pin_tumbler \|pin-tumbler]] lock made by the Japanese company [[WEST]]. The 917 has a [[dimple]] key, and multiple [[Pin_tumbler#Components \|bibles]] containing 20 pins, arranged in rows of seven on the left and the top of the vertical keyway as well as six on the right. The 917 employs the same pins, fundamental designs, and primary security features as the smaller, 12-pin [[WEST 916]] model.

Each of those chambers contains a set of key pin, driver, and spring. A seventh chamber in the bible on the right side contains a spring-biased bearing that aligns with an indent to center-bias the plug.

	The dimple key of the 917 has four cut depths for side pins and three, different cut depths for pins in the top row. The key is bitted on the sides and edges of the blade and is reversible. To open the lock, all 20 ~~pin-tumblers~~ -- across all three rows of pins -- must be aligned at the [[shear line]].

	WEST utilizes a variety of [[security pin]]s to deter ~~picking~~. Pin stacks incorporate stainless steel key pins with two sizes of brass driver pins to match. The 917 uses a mix of mushroom spool drivers and standard ones. Drivers are cupped to allow the spring to nest inside the pins. Key pins are a combination of t-pins and multi-section tapered spools which are torpedo shaped to create overset traps. These pin designs match over- and/or counter-milling of the pin chambers in the core to catch pins as they are lifted to shear.

	The [[WEST]] 917 operates with [[dimple]] keys but functions the same as a standard [[pin-tumbler]] lock. The lock uses 20 chambers for pin-tumbler stacks. There are seven stacks in the top and left side rows as well as six stacks on the right side. Each of those chambers contains a set of key pin, driver, and spring. A seventh chamber on the right side of the bible contains a sprung bearing that aligns with an indent in the core to center-bias it.

			The WEST 917 is disassembled in the same way as a traditional pin-tumbler cylinder.

			# Remove the rear plate
			# Insert the key and turn the [[plug]] 30-45 degrees.
			# Withdraw the plug from the cylinder. (A [[plug follower]] and [[core shims]] are strongly recommended)
