I just posted a thread about this too. i have no idea what could be wrong, i dont have an alarm or the oem keyless entry just the key. It scared the shat outta me too but mine is on the passenger door. i really wish i could find out whats wrong i'm gonna take my door panel off this weekend if it doesnt stop. the odd thing is is that my locks were working fine today but it was still clickin like a machine gun hmm... weird
