I'm not so sure that's correct. I just bought my Camry Hybrid and asked about the alarm. The dealer (the fourth I've talked to all with the same answer) had never installed the alarm on the Hybrid and wasn't sure how it would work. The key question is--can it unlock the doors without using the remote? I'm certain it can unlock the doors using the remote (from "up to 80 feet away")....but I'm less sure that they remoteless entry will work (so that you just need the remote in your pocket to open the door).

I think the problem here is that even the dealers have no clue how to do this, though they all think it should be able to be done. Until someone actually does it...

Oh, yeah...and I decided not to get the alarm. It was going to run something like $700 after installation (seems super high to me), so I skipped it. The car has an engine immobilizer so all we'd really add by adding it is something to discourage vandalism and theft after glass breakage.
