Attempt to
start car, leave key on 15 min or so until the security light goes of,
turn key off, then back on, do not try to start just leave key in on
position until security light goes off. Repeat 5x takes about an hour.
Some older chevy you had to do this 2-3x, newer cars 5-6.

Good luck. This procedure should be in your manual.
