Questions

How do I know it will fit my safe?

Measure the diameter of the round opening in the safe door where the current cylinder sits. If it measures between 17.5 mm and 18.5 mm, this 18 mm cylinder is designed to fit.

Not sure? Send us a photo and we'll check it for you before you order.

I've lost every key — can I still use this?

Fitting a new cylinder needs the safe door to be open. If your safe has another way in — a keypad or code — open it that way first, then swap the cylinder and start fresh with the two new keys.

If you're locked out completely, please contact us before ordering.

Measure once, order with confidence.

Check your opening measures 17.5 – 18.5 mm, then add the set to your order.
