The lock jamming should be permanent as consequence of spamming LP.Make LP cooldown 10 or 20 seconds, during these seconds, its possible to LP but with chance of jamming, each use of LP during the 20 second cooldown will increase chance of jamming.For cars and doors, these would have to be able to be fixed. Only with footlockers in enc, should it be permanent.
At least doors can be opened with explosives.
Then other ability to open doors/boxes/cars/anything should be shown (kick in the door, dynamite,grenades,rockets etc.)
