Hi i have a 1997 grand prix the keys where lost so i got a new ignition switch but can not remove the old key cylinder because i dont have the keys to turn it in the start position to release the old cylinder i have been told to drill it out but will this work on a 97 with ant=theft

Hi,
Yes it will work that way. Just drill out the retaining clip in the ignition switch that holds the lock cylinder in place. Be care ful with the switch. The new lock will slide right in with key in start position. If it has a rectangular looking metal pin securing it, drill into the plastic part of the switch with a 5/32 drill bit about 1/2 inch back toward the lock cylinder to take out the pop rivet holding the spring loaded pin mechanism in place. The spring comes out and push the pin down with a flatblade and pull lock out......Mike
