Hello Triston Biggerstaff,

You can unlock the phone yourself

  • Remove and insert the battery into your phone.
  • Then press and hold Volume Up + Volume Down + Power button together.
  • Release them when the red Motorola logo appears.
  • Now you will see Android logo -> press Home button.
  • Scroll down to the option "wipe data/factory reset" using Volume Down to scroll, and Power button to confirm option.
  • After that choose option "Yes-delete all user data".
  • Afterwards select option "reboot system now"

Note : all data will be lost
