If you unlock the car with the keyfob and don't open any doors or the boot it will re-lock automatically after about 30 seconds. If you gave just stopped the car and take the key out of the ignition then no, it will not lock automatically.
The car re-locks after 30 seconds to prevent you accidentally leaving the car unlocked if you have pressed the unlock button by mistake.
