In this video, I demonstrate a lock function that most locksmiths have never seen — a clever (and slightly evil) little device that intentionally locks the resident out and stops their own key from working.
This isn’t a fault.
It isn’t worn.
And it definitely isn’t accidental.
This is a deliberate lock cylinder modification, designed to work exactly this way.
I break down:
What this device is and what it’s meant to do
Why does the resident’s key stop working on purpose
How and why this lock function exists
The internal mechanics of this nifty little cylinder modification
How locksmiths can work around it when encountered in the field
This is one of those lock designs that makes perfect sense once you understand it — but if you don’t know it exists, it can easily catch you out.
If you’re a locksmith, apprentice, or just someone who likes weird and clever lock design, this is something worth seeing.
Chances are, you’ve never come across this before.#drlock

![Lock Picking 3,000 RPM Orbital Lishi VS Combination Cam Lock [1332]](https://i.ytimg.com/vi/nMpxX6BoIYs/mqdefault.jpg "Lock Picking 3,000 RPM Orbital Lishi VS Combination Cam Lock [1332]
In this video, I take a combination cam lock and show you the lazy way to open it. Instead of picking it properly, I decided to have some fun and go with the easy option – grabbing my 125mm Orbital Hero, also known as the Dewalt 18V grinder, and cutting straight through.
Sometimes locks are meant to be picked, sometimes they’re meant to be decoded… but in this case, it was all about the grinder. Quick, loud, and a bit over the top – but effective!
This video is more about demonstrating the “brute force” approach and having some fun with the process. Of course, in the real world, this isn’t the recommended way to deal with a lock, but it shows just how quickly a grinder can take care of business if you’re not in the mood for delicate lockpicking.
If you’re curious about how long it takes, what it looks like, and how much fun it can be, watch along as I fire up the grinder and open the lock the easy way.
