ERROR: cannot launch node of type [teleop/teleop_key]: can't locate node [teleop_key] in package [teleop]

edit

Hello I took over a project on ROS and I'm still pretty new to the environment. I'm currently using ROS Kinetic and Ubuntu 16.04. I'm trying to launch a simple keyboard_teleop.launch program but get this error:

process[master]: started with pid [27909]
ROS_MASTER_URI=http://localhost:11311

setting /run_id to 25d5ccd0-cd3c-11e8-9d38-74e5f9149b23
process[rosout-1]: started with pid [27922]
started core service [/rosout]
ERROR: cannot launch node of type [teleop/teleop_key]: can't locate node [teleop_key] in package [teleop]

Here is the launch file:

<?xml version="1.0" encoding="UTF-8"?>
<launch>
  <!-- teleop_key already has its own built in velocity smoother -->
  <node pkg="teleop" type="teleop_key" name="teleop_keyboard"  output="screen">
    <param name="scale_linear" value="0.5" type="double"/>
    <param name="scale_angular" value="1.5" type="double"/>
    <remap from="teleop_keyboard/cmd_vel" to="/cmd_vel"/>
  </node>
</launch>

And the CMakeLists
