Yes, mine is the one-button dealer-installed RMST. The odd part is, is that what looks to be the override button is at the very bottom of the instrument panel, below the steering wheel, and it's actually a very small box with a dark blue button in the middle and it has a blue LED, which I noticed comes on when the car is off and the doors locked. The button looks nothing like I've seen, with a long wire and a bulbous end with a black button on it.
