(168) How to Bypass Euro Thumb turn Cylinders (Protect Yourself!!!)

My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. Thes i banned in my country we have many times a smal window in our front doors or a mail opening.
    You can easy break the window or go trough the mail opening and turn the lock open.

  2. I got a lock from my dad similar to this and noticed the same thing. It's pretty freaky about this trick. Just glad to find someone sending a warning, Thanks bosnianbill!

  3. You're right that it is always easier mounted in a vise, but thats simply not practical for hobbyists. However, there are commercially made bypass tools (sold by Peterson, Sparrows, etc) that ARE strong enough to turn the tailpiece on Euro Cylinders while they are installed. I have done this bypass on many doors in Central Europe using Peterson tools with absolutely no problem. Most good mfgrs today know of this technique and have redesigned and protected their locks tho. Thanks! bill

  4. The thing is, when you try this bypass method when the lock is in the actual mechanism in the door, and it requires a lot of force to actually turn the lock to the unlock position. It is much easier with a lock in a vice or out of the door.

  5. I take that back… I bet that filling in the hole in the sliding bit of the lock cylinder's side of the cam would prevent the wire from reaching around and engaging the locking cam. Hmm.

  6. I think it's a basic flaw in the fundamental design of most europrofile locks and how the cylinders engage with the cam. I can visualize a design without the bypass, but it's not clear that it would be easy to retrofit.

  7. WTH!!!
    That is why I like the feature on the Tokoz Pro, you can just pull out the thumbturn in your direction and even if you have a key the core on your side will move with the key but the locking bolt won't 🙂
