But if you manually lock it, the alarm doesn’t activate. At least that’s how my Viper system works.
I’ll take the two little guys (Yorkie Poo siblings) with me to pickup takeout food. They stay in the truck while I go in the restaurant. I have to hit the inside door lock button to lock the doors rather than using the embedded sensor on the exterior door handle or the fob. If I don’t do it that way, the boys set off the alarm before I’m even across the parking lot. I’m pretty sure they think it’s funny. Using the interior button doesn’t set the interior motion sensor I guess, but I believe the alarm would go off if someone tried to break into the vehicle.
It’s just too much newfangled stuff for an old guy to remember.
I only use my fob to lock my car this way I can’t lock my keys in the car.
There are two types of fobs.
If you can walk up to your car and unlock it by touching the door handle, even with it in your pocket/purse, you have the one that transmits (a short distance) all the time, or the “RFID” as it was called here.
On some, you have to hit the button to unlock the door. I don’t know if any car makers are still doing it this way, but I used to have one. It does not transmit unless you push the button. (You can’t just grab the handle and get in.)
For either one, hitting that button broadcasts the code in all directions, for a pretty good distance...
