Locked only key/fob in trunk

I just locked my only key and fob in trunk. I
already armed the car. But the thing is, the locks
on the front doors haven't been physically going
'down' when I arm it, and I don't hear the
mechanisms when I arm it. But i DO hear them
when I disarm it.
So before I take a risk, of the alarm sounding and
the door actually IS locked (because I believe I
can crawl thru the backseat to the trunk), I
wanted to see if anyone out there has had the
same experience.
