When you do the key 1 key 2 key1 again programming sequence, you are in effect trying to enter the OEM key programming sequence, for this to work properly:
1. you need the 2 OEM master keys that came with the vehicle, ( no programmed extra keys or valet keys)
2. The doorlocks should cycle once when you insert the first key for the 2nd time ( step 8) this confirms that the oem key programming was properly accessed. (do not let too much time pass between key 1 and key 2 steps)
3. Disconnect the red 6 pin connector during the programming sequence, once programmed re-plug this connector,
Thank you,
