Get an LMC5 and install it. And do the brown wire mod explained on page 2 of the install instructions WHEN you do the LMC5 install!!!!!!!!
Your problem started as a low or weak battery or loose or corroded battery connections including at the starter. Those are the MOST COMMON
cause of the column lock symptoms. Get the battery checked out. Just because the car can be started does NOT mean the battery has the proper voltage to operate the column lock system. It relies on a minimum voltage level. The starter requires current that can be generated even with low battery voltage....
