Lock pick guns use a technique called "raking" to pick locks. This is a quick and easy method but won't have the desired result on high-security locks. Even better, high-security locks have various mechanisms which make them difficult to open with such techniques.
The GOSO Strong Lock Pick Gun is designed with this in mind. This set includes the Lobo Idea lock pick gun along with other more complex tools for locks that can't be unlocked through raking.
The lock pick gun kit includes picks for various locks. The most notable of these are the cross lock picks, which are good for saving time if you find a cross lock.
It is quite common for locks to jam when the wrong key is inserted. This kit also includes a key extractor in case your key gets broken in the lock.
