Why is the android device manager unable to lock my phone?

[AC Question]

Hi there,

I have been using an LG 3G ever since my previous phone got stolen and thought it might be wise to set up the android device manager. Whenever I lock the phone remotely, however, the message and lock show up, but it does not require me to enter a password and I can just bypass it by pressing the home or back button. This kind of seems to beat the purpose... Is anyone else having this same issue or am I just missing something really obvious?

When the phone is in the locked screen during normal use do you have it setup for locked screen or can you just swipe to unlock?
