You can by pass security system , by adding resisters to the wires underneath the steering column. You will test the omes on each side of the chip on the key and whatever amps they read is the amps you buy on the resisters . There will be a orange wire , that is the wire you tie the resisters into.

Tried the Relearn Procedure on my 1999 Buick LeSabre Custom, and it was not successful. The security light never turned off. Didn't turn off after 10, 15, or 20 minutes.
