Juwel 4×4 New Locks Prodecoder Automatic


The New Prodecoder Automatic Juwel 4×4 is made specifically for the new Juwel 4×4 lock that is now on the market. The new Juwel lock has specific cuts on every plate that is made to “trap” every lockpick tool inserted, but the key. Below you can see an image of the lock inside. With the new decoder we made, we overcome those cuts and we skip the “trap” that Juwel has put there. Thanks to the new pins this decoder can be used safely on both old and new Juwel 4×4 locks.

The tool will lift each each lever (plate) of the Double Bit Locks to a specific height in order for the locking bolt to move. Another key point is how easy you can repair any broken or twisted pin – just pull out the broken one and replace it with one of the spare pins provided in your kit.
