The D9 is a high pin count lock with a dimple key made by GOAL. It contains nine pins, arranged in rows of three on the left, top, and right of the keyway.
Please note: the D9 is very similar to the larger, 21-pin Goal V18 model. The two locks share the same pins, fundamental designs, and primary security features.
Principles of operation
The GOAL D9 utilizes dimple keys but functions the same as a standard pin-tumbler lock. The lock uses nine chambers for pin-tumbler stacks. Each of those chambers contains a set of key pin, driver, and spring. The dimple key of the D9 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 nine pin-tumblers -- across all three rows of pins -- must be aligned at the shear line.

GOAL utilizes a variety of security pins to deter picking. Active pin stacks incorporate seven total lengths of stainless steel key pins with two sizes of steel driver pins to match. The D9 uses a mix of thin and thick lipped mushroom spool drivers. 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 overmilling of the pin chambers in the core to catch pins as they are lifted to shear.
| D9 pin sizes (mm) | ||||
|---|---|---|---|---|
| Top row pins | 4.20 | 4.75 | 5.20 | |
| Side row pins | 5.15 | 5.65 | 6.15 | 6.50 |
Two small sprung bearings are housed in the lock core to center-bias it. These bearings interact with matching detents in the bible when the key aligns the core to the locked position. The D9 can be drilled with three additional holes for construction keying.
Disassembly instructions
The GOAL D9 is disassembled in the same way as a traditional pin-tumbler cylinder.
- Remove the rear C-clip
- 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)
- Note: the three bible covers of the D9 cylinder can be removed easily and non-destructively.
- This makes gutting and re-pinning possible without removing the plug.
