I learned at school that coming from a 2002-2008 GM Master ASE tech (teacher now at UTi) told our class about a simpler way on how to reprogram a key for free. This is what he told us:
1. Have original coded key in ignition switch with new uncoded key in hand.
2. Turn original key to ign/acc switch
3. Take out key
4. Within 5 seconds have new uncoded key into ignition switch
5. Turn to ign/acc switch
6. Wait 10 seconds
7. Key is now coded.
Just wondering if that is anyway true. Sounds legit to me.
