⭐ ✔ You Receive TWO Keys — Always

No matter which size you select from the dropdown, you will receive TWO matching keys in that exact size.

This is now stated clearly and prominently to avoid any confusion.

✔ Why This Key Outsells Every Copy

• Official UK Registered Design — government‑certified originality

• Superior strength vs. cheap clones

• Perfect fit even in tight, awkward spaces

• Over 50 sizes available

• Every key checked with a plug gauge before dispatch

• Printed from the authentic registered design, not reverse‑engineered

This is the only Lockshield Key made from the original design files.

✔ Measure Correctly — Get a Perfect Fit

You must measure your valve correctly. You’ll need:

• AF (Across Flats)

• Spindle diameter

Check the diagram in the photos section for guidance.

⚠ IMPORTANT — Photo Requirements

If you send a photo for help choosing a size, it must:

• Show a tape measure actually touching and measuring the valve tab

• Be taken directly above the valve

• Be in focus

• Show the measurement clearly across the flats or square

If the tape measure is near the valve but not measuring it, the photo is useless. Make sure the tape measure is physically aligned with the valve tab.

If you’re unsure, message me — I’ll help you choose the right size.

✔ Important Notes

• If you order a square key, you will receive a square key

• If your valve is seized, this tool will not free it — replace the valve first

• Colour varies depending on what filament is running (orange, yellow, green, white etc....)

• Specific colours available on request

• Keys may differ slightly from photos (length, finish, shade) — but always fit perfectly

✔ Built for Real‑World Use

3D printed in high‑strength material, this key fits modern flat‑tab lockshield valves and traditional square valves. Designed for:

• Radiator balancing

• Heating system optimisation

• Professional installers

• DIY users who want accuracy

✔ Custom Sizes Available

If your size isn’t listed, I can make it.

I hold the original 3D models, so customisation is fast, precise, and reliable.

✔ Satisfaction Guarantee

My aim is for you to be 100% satisfied. If anything isn’t right, message me — I’ll fix it.

But please remember: You must measure your valve correctly. I cannot determine your size from a photo unless a tape measure is clearly visible and actually measuring the valve.
