i replaced the steering column in my mustang and had to switch the pats module from the old to the new column. i forgot to disconnect the battery when i did the swap and set off the anti-theft in the car. i had a shop reprogram the keys to the car and it didnt work so they plugged a scanner in and it cant get a signal from the computer. what could be possible solutions for this so that i dont have to go buy a new computer for the car?
