I have become Mazda-less again January 8, for the second time in three and a half years. I am looking at a P5 whose owner says the driver keyless lock doesn't work.
I found a keyless entry module on ebay and would like to know what this does. And would I need to replace this or just the actuator? I tried googeling the difference between the two and haven't had any luck. I would love it if someone could educate and enlighten me on the difference.
