The remotes that we've had, that had a panic button, what it usually does is honk the horn repeatedly until you press it again. One time when we were in Mom's Pacifica at a nice restaurant, Dad accidentally pressed it. That car had very loud horns, and that was an uncomfortable interval while we got the key and figured out how to make it stop. And there were several HPD officers there too (which didn't help with the whole vibe!). Those remotes are fun anyway because they are made into the top of the key. The car will freak out if you unlock it with the key instead of using the button, and it WILL NOT START with any keys other than the ones the dealer cuts and programs. At $300 each. I talked to a buddy of mine who's been a professional locksmith for many years, and he said he had been to the Mopar school; those cars are virtually impossible for an independent to access the computer that runs those systems. This is the 2004 station wagon/crossover Pacifica, from when Chrysler was hooked up with Mercedes. Great cars, but so much of them is unique to those cars.
