TSA Approved Luggage Locks with Steel Cable 4 Digit Combination Lock with Inspection Indicator Keyless Padlock for Suitcase Backpack Baggage (2 Pack)

Anyone used this to lock EV charger (or charging adapter) such as J1772?

Lock wont open

Lock one. i set code once and it worked. lock two. i set code, same code and it works. i closed lock one. moved numbers. it locked. i set code to ope

If resetting the PIN is so easy, what is there to prevent someone from opening your combination lock?
