Nup they dont do that. The only time mine autolocks is if I walk up to the car and unlock it with the smart key remote but then dont open any doors, then it will autolock again after about 20 to 30 seconds. It will only autolock if it was locked to begin with and then unlocked with the remote but no doors are opened.
On another issue I want the doors to autolock whilst driving but mine doesnt have the option in my country. Very annoying. I want to try an american door lock ecu!
