for me it was an odd mix of sliding on my mobile a very small amount keeping pressure to build the gage and then releasing. so it was not swipe speed or strength just some movement and waiting to get the gage right
The chest lock needs to have precise strength timing. Basically you want enough strength to lift the lock exactly to its opening, and nothing more or less. Keep using different strengths and see which works best. Took me about 5 minutes in the first try to get all of them.
