In this video, I show you how to re-key (repin) a Whitco Blaxland / Mawson lock cylinder step by step. This lets you change the lock to work with a new key without replacing the whole cylinder.

This guide covers:

How to dismantle the cylinder safely
Removing the current pins
Changing the pins to match a new key
Reassembling the lock correctly

Rekeying is a useful skill for DIY locksmith enthusiasts and can save you money by avoiding full lock replacement.
