On the same topic, I asked the dealer about activating the passive entry ( I replaced the door handles and door wiring harness) and they wanted $160. I just purchased JSCAN and did it myself.
I call in the week before it renews each year and tell them I'm going to cancel. They then give me the $99/yr (+ BS fees). In the rare case they don't, I go ahead and cancel and I'll get the offer in the mail within the first month.
