Not sure this tool fits your vehicle?
Ask the assistant: it checks this listing against your make, model, year and market, and tells you when it cannot confirm.
The LW4 is the five-pin Lockwood C4 tool. Lockwood is the default residential hardware brand in Australia and New Zealand, and most of its door cylinders are built on the C4 keyway. This version reaches five pins — the standard configuration on the majority of those doors.
It picks the cylinder and reads all five pin depths in one pass, so a lost key becomes a cut key rather than a cylinder replacement.
Which locks this tool fits
- Keyway — Lockwood C4. Five-pin Lockwood residential cylinders: entry sets, deadbolts, lever hardware.
- Cut count — 5. Six-cut C4 cylinders take the LW5.
- Region — AU/NZ. An Australian residential profile, not a North American one.
If a key has six cuts, this is the wrong tool — the sixth pin sits beyond the LW4's reach and the decode will look plausible but be incomplete.
What "2-in-1" actually means
Pick and decoder in a single body: tension, lift each pin to the shear line, read the depth as it sets. Five depths, then a key.
Decode-then-cut workflow
- Count the cuts and confirm the C4 stamp.
- Tension lightly and insert.
- Read five depths front to back.
- Cut the key on the recorded bitting.
- Test and log the key.
Three mistakes that cost the most
- Using LW4 on a six-pin door. The sixth depth will be wrong.
- Assuming C4 for every Lockwood key. Check the stamp.
- Heavy tension. Five-pin C4 plugs are forgiving until you force them.
Frequently asked questions
Is LW4 enough for most Lockwood doors?
For five-pin C4 cylinders, yes. Six-pin doors need the LW5.
Will it fit a Gainsborough lock?
Only if the cylinder is on the C4 keyway; Gainsborough's own profile is usually TE2.
Can I cut a key from the decode?
Yes, with the correct C4 blank.

Ordering, Shipping and Aftercare
Buying the right tool
Match the keyway code in the title to the vehicle or lock you are working on. The cut number (5-cut, 8-cut, 10-cut) describes the bitting geometry, not tool quality.
