Opening a cabinet lock without a key can be a frustrating experience, but it is possible with the right tools and techniques. There are a few different ways to do this, and the best method will depend on the type of lock you have.
One common way to open a cabinet lock without a key is to use a bump key. A bump key is a specially cut key that can be used to open a lock by rapidly inserting and turning it in the lock. This method is not always successful, but it can be worth trying if you have the right tools.
