Tryout keys are one of the tools that are used when lockpicking a lock. These keys have spacing patterns and custom depth that are made to manipulate everything inside a lock and are capable of rapid brute forcing all keying depths for the lock.
There are a lot of tools that you can use to crack open a lock but it often ends up into a bad result. To avoid messing up with the internals of the lock, immediately contact a professional locksmith instead.
