Can TSA open any luggage lock?

TSA agents can open TSA-accepted locks with a master key. Non-TSA locks will be cut off with bolt cutters. TSA will leave a notice inside your bag if they inspected it.

Do luggage locks actually prevent theft?

Locks deter opportunistic theft — someone reaching into a bag at the carousel. They won't stop a determined thief with tools. For high-value items, carry them on instead of checking.
