Programing Entry Remote
The manual is the first place to look. For some reason GM puts one in the car.
It depends on if you are adding a remote or replacing a remote. The C6 has "memory" slots for 4 FOB's. If you are gonig to add a remote then I can give you directions, but if you want it to take place of the FOB you lost you will need to take it to a dealership. A service advisor (with a brain) should know how to do this, they will need a "scan tool."
To add a FOB do the following procedures:
1. The Vehicle must be OFF.
2. Open the rear compartment
3. Place a known key fob within the interior of the vehicle.
4. At the rear of the vehicle insert the vehicle key in the rear compartment lock cylinder located in the lower left and cycle the key 5 times within 5 seconds.
5. The DIC will display a message: READY FOR FOB X (X= fob 2,3, or 4)
6. Place the replacement key fob in the glove box fob pocket with the buttons facing right.
7. A beep will occur and the DIC will display: READY FOR FOB X (X=fob 3 or 4) or MAX FOBS LEARNED.
8. If programming additional key fobs, repeat steps 5 and 6, or press the OFF/ACC portion of the ignition switch to exit programming mode.
9. Operate the active portion of each key fob to finalize the programming and verify correct system operation.
Hope this helps.
