Keyless entry code

[TB55123]

Is there a way to determine the keyless entry code on an 2002 Silverado Z71 without the remotes?

Thanks.

It should be

GM/LEAR: 15042968
FCC ID: KOBLEAR1XT
CANADA: 3521 102 1718

Also, you can pick up replacements on Ebay for ~$15 each. The dealer charges ~$60 each.

yep that's what I'm tryng to do, purchase openers on ebay for my recently purcashed 02 Z71. The codes should be on the vehicle somewhere shouldn't they?

Each fob had it's own signature. I did it once and can't find it now but I believe you turn the key on/off three times and then a specific key (lock/unlock on the door, can't remember if that was it) and then you touch the open and close on all the fobs you will be using, each one in succesion. The computer will time out and only the fobs used in that session will work as now the computer will only recveive from those fobs. Some dealers try to charge you but it only takes 2 minutes and no tools.

I will try to find the papers I have. Good luck.
