Sound on unlocking and brakes acting funny

325xi 02 116k
Anyhow, when I unlocked my doors today I noticed an odd little buzzing noise. It only happens when I unlock them, not when I lock them, and it happens everytime. They never fail to unlock, the noise is just unnerving.

Brakes:
Replaced pads and rotors about 2 months ago due to warped rotors causing vibrations when braking. Maybe 3 weeks afterwards I got a slight vibration back in the breaks, and now it's nearly back to where it was initially. On top of that, my breaks squeal a bit when I press lightly on them as if the pads were in need of replacement. It's my understanding that pads should last longer than 2 months.
Ideas?

The R.I.F. Principle....(Reading Is Fundamental)

The term is "BRAKES", Skippy, not "breaks", which is something altogether different. If you had done a little homework, you would have found that rotors *rarely* warp, and your problem is probably either suspension-related, or pad deposits built up on your rotors. Try bedding the brakes again.

I inherited the car with the "warping" issue. And I apologize for the misspelling my overly sympathetic friend, it's 1am here and I've just gotten done with work (on a business trip, not home). I was told that it was "warped" rotors when I got the car so that's what I reported the problem as, as I had no idea. Also RIF == RTFM, but I suppose that's a less kind way of putting it. & I appreciate your response despite its caddish nature. I'll be sure to do more research in the future.
Post fixed for your pleasure.

the unlock buzz is most likely the unlock relay built into the GM module. if it still works leave it alone.

I would have the front suspension inspected. sounds like the thrust rod bushings are worn to me.
