I was playing around with the starting code on the nav screen and managed to lose track of things and set off the alarm. I disconnected the negative for 5 mins, reattached it and watched for the 10 min count down. It counted down for a couple of minutes, but the screen went blank. I waited over 10 min on a timer, but no good.

The owner's manual says the procedure works before the alarm goes off. Since it did, I guess I have to go to step 2 to really reset everything.

I called the dealer and they said it would have to be towed in and reset on their computer.

Maybe there is a way to do this at home?

Certainly appreciate any help. Thanks, Carl
