JL Practice Lock

Repinnable 6-Pin Mortice Practice Lock with Full Pinning Kit

The JL Practice Lock is a fully repinnable 6-pin mortice cylinder designed to grow with you as a picker. Whether you're drilling single pin picking (SPP), learning to feel driver pins, or practicing impressioning — this is the tool that lets you set up exactly the challenge you need.

What Is a Mortice Cylinder?

A mortice cylinder is the type of lock core used in deadbolts, padlocks, and euro-profile locks. It operates on the same fundamental pin tumbler mechanism you'll encounter across thousands of real-world locks, making it the ideal format for building genuine picking skill — not just muscle memory on one specific lock.

What's Included

Everything you need to start repinning immediately:

- 6-pin mortice cylinder tapped with grub screws for easy access

- Full pinning kit — all KW-size driver pins including:

- Standard pins

- Serrated pins

- Spool pins

- Master wafers

- 4 key blanks for impressioning or cutting practice:

- 2x KW11 (6-pin)

- 2x KW1 (5-pin)

- Allen wrench for the grub screws

Why Repinnable Matters

Once you can open the lock at one difficulty level, pull the core, swap in spool or serrated pins, and immediately have a new challenge waiting. No buying a new lock every time you progress — this one adapts with you.

Great For:

- Single pin picking (SPP) — learn to feel individual pins set

- Raking practice — get feedback on rake technique and timing

- Impressioning — use the included blanks to practice marking and filing

- Locksport training — set up security pin combinations to match real-world locks

Who This Is For

Intermediate pickers ready to go beyond transparent locks and start working with real security pins. Also ideal for anyone who wants a dedicated repinnable cylinder without cannibalizing a lock they use in the field.
