Can anyone tell me how to program key less entry remotes for a 2002 Chevy trailblazer LTZ that has the memory for the driver 1 & driver 2. The dealer only furnished the driver # 2 remote. So I privatly purchased extra set. The #2 remote matches the one I have as far as the numbers on the back & the #1 is only one digit off. Does this take special programing.
Thanks
