What happens when you press q? Simply nothing or is there another action ?
[DOUBLEPOST=1434183920,1434182237][/DOUBLEPOST]Make sure your car is on and your in the driver seat tap q once. If that does not work then it seems like your missing a keybind.
[DOUBLEPOST=1434185998][/DOUBLEPOST]I'm not to sure. If you open gmod settings and try find keybinds (controls) then look for a default button and click it to see if that does anything. ((Sorry at work so can't have a look on how to exactly do it ))
ask someone to type in their console 'bind q' then it says what it's binded too and then you just have to type in your console 'bind Q "things from the other guy"
