Left/Right deletes object?

Hi,

Not sure if this is the correct place to ask but for some reason if the left or right keys are pressed to turn a vehicle it deletes the object from the scene rather than turning it, this occurs even if the keys for left/right are rebound to other keys
There is no shortcut for delete object as far as I have found either. I have the blueprint picture here in case there is something wrong with it
Any help is appreciated

Thanks

EDIT : Fixed
