Damn, was hoping there would be an easy answer.... it's to get the sound of the engine turning over but not starting. It's for a scene in a horror movie where they jump in the car and in true horror movie style it won't start. It's just the sound I need, I could use a library FX but wanted to get an original recording, might give the transponder key thing a go as that's probably dependent on the individual car and least likely to damage anything.
Cheers for the help everyone
