Hello. Have you tried this.
Disconnect battery cables for 10 minutes so computer should reset itself, reconnect the cables, so theft light blinks every 5 seconds, with key is out or in off position, this means system is armed and working properly.
When trying to start the theft blinks and computer does not recognize key so try the spare key. And they are chip keys. Or here is another one
insert 1st key in ignition turn on and back off, remove and insert 2nd key turn to on then off before removing. Leave key in off until security lights turn on for 3 seconds and then repeat the process to reset and additional key, now. Sandra
