This would be a great help for the dealerships and mechanics on our server to lock the car lifts as other players can access the lift and remove the parts even if the vehicle is locked. 

It may not be possible but my hope would let people still use the life on  and off just block the use of the modular controls

Thank you for your work on this already amazing plugin :D

Not sure if this would be possible but it is an interesting idea.

I just came here to ask the same thing. :) 

Voting this up.  Would be great to have.
