How to resolve a GM vat system problem?

Asked by Jan 05, 2017 at 01:51 AM about the 1998 Chevrolet Cavalier Base Coupe

Question type: Maintenance & Repair

My 98 chevy cavalier has always been
dependable. Until last month when the
ignition cylinder lock needed to be
replaced. Since then the Gm vat
system has kept my cavalier from
starting by interupting the gasoline
flow .
NOTE: my original ignition keys were
simple metal keys w/ no chip on the
keys!  And the keys to the new ignition
cylinder lock doesnt seem to have
chips on them. Although the end of the
keys are encased in a black key cover.
So i cant be sure.

1 Answer


Yes they are chipped, the dealer will have to reprogram the system to reconise the new key and tumbler system.
