Been told by a friend that if you strip down the passenger side doorlock it will have the 5 digit keycode stamped on the lock cylinder. Apparently it's a Mazda key code as they supplied the locks and ignition switches for Probes. As long as it hasn't been changed , should be on there .He owned his own garage , was hands on in the workshop and is usually very reliable for info .Hope this helps .

 

Thanks for the info.

 

Glad to help , hope it works .
