I had to go back to my dealer today to pick up my checkbook that I left in my trade. While there I asked them about changing my keyless entry so it unlocks all doors with 1 press, the default is 2. I was surprised to hear him tell me I'd have to schedule a service appointment as they'll need to reprogram the computer! I was surprised. My 2000 Neon came the same way but in the owner's manual it had instructions on how to change it. It seems silly to me to have to schedule a service appointment for something so trivial.
