Changing BIOS password to turn off Lojack

If the password in the BIOS is changed can the laptop still be monitored? I got my laptop a few months ago & I just found out about this thing called "lojack". I don't think I approve of this possible invasion of privacy either. I'm very responsible when it comes to keeping an eye on it so I don't think I need their services. I did change the password but just not sure if that helps.
