A very useful keychain accesory. Opens all coin deposit locks without the need for a coin and can be removed immediately.
This redesign of my original Universal Trolley Coin features a strong solid body with a sheath for the special arm, which can be used to open the previously undefeated ‘drawer-style’ locks, as well as a slightly larger 24.5mm coin adapter to ensure maximum compatibility.
Printing instructions
PETG works best, but you can use other materials, even PLA. Generic settings for 0.4n and 0.2l work great, just increase the number of perimeters to ≥3. You might want to use 100% infill. Print as-is and fold afterwards. You might need to slightly scrape the end of the arm to make it fit snugly into the sheath, depending on your printer.
Use in the field
Push-style locks
Most locks out there are of the simple, push-style desing. To defeat these, just insert the tool into the coin slot. Once the lock opens, you can safely remove the tool again.
Drawer-style locks
Drawer-style locks require the use of the special arm. (the following pictures show an earlier version of this tool, but it works the same way)
1. Insert the arm alongside the drawer, then close the drawer as far as it will go.
2. Hold the drawer jammed and pull out the arm.
3. Close the drawer.
Testing & validation
Testing has been done on locks like these or these in various stores in the Czech Republic, Germany and Ireland. All parameters of this tool have been carefully selected to make it truly universal, hopefully worldwide.
If you encouter any issues or oddities while using this tool, I'll be happy to hear about your experience. Feel free to use these test samples with varying coin diameter and report your findings.
