Afraid I must disagree with you. We have a New Beetle and recently traded our Jetta. Both lock all doors via the remote. However, to unlock all doors, you need to hit the button twice. I think that’s a nice feature - if you’re alone, you don’t necessarily want all of your doors unlocked automatically.
My Scion works the same way - 1 push unlocks the driver’s door, 2nd opens all the doors and the hatch, each time with a non-horn beep. Locking is 1 push for all doors, and if one or more door is not latched, the beep is drawn out till you shut the offending door(s). What I don’t like about the Scion is that when I turn off the ignition, all of the doors unlock. It never occurred to me to check the manual to see if I could disable that feature - I’ll do that.
And, for the record, if I actually honk my horn, it’s probably an accident. Honestly, when I need the horn, I can’t always remember where the pressure point/horn button is.
