In this video, I show you how to file lock pins to size properly for the best possible results.
I demonstrate two different methods, and then the cleaner professional method using a small rotary tool.

Correctly sized pins make a huge difference to how a lock feels and operates.
This technique improves smoothness, reduces binding, and helps the lock last longer.

If you’ve ever filed pins by hand and ended up with rough or inconsistent results, this video will show you a better way.#drlock #Locksmith #LockShop #Locksmithparramatta
