Esx_vehicleshop change keys

So the problem that i am having is that when a player wants to go look at a vehicle normally most people would rev the engine to hear the sound of the car. But what i am wanting to do is change the space key in the file to do something else instead of selecting. B/c when i go into the shop to go look at a car & i hit space it will take me to the screen on are you sure you want to buy this then if i hold space it will skip that & buy like 4 of the cars.
