After you complete the second mission Miami (The Finish Line) in Hitman 2 you will get (as long as you try to score a large number of mastery points, which will advance you to 2nd level) a Lockpick Mk II. Once you've equipped yourself with it on any mission, you'll be able to open any lock in the mission area without the need to obtain the right key or use a crowbar. The exceptions are:
- Some story related locations,
- Electronic locks.
Electronic Key Hacker
After you complete mission 6 in Hitman 2 - Isle of Sgail (The Ark Society) you will unlock another useful item - Electronic Key Hacker. This device will allow you to bypass the lockpick restriction: you are able to open electronic locks that require magnetic access cards. The device has a significant limitation: it can only be used once. However, you can place a second device on a map (smuggling).
