Hi, all new to baord and trailblazer , How do you program keyless remotes for a 2002 Trailblazer ZT1 ? Thanks

Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.

When I did mine, what fooled me is that it took a few (5-10) minutes for it to "take" after the horn blew. I went in the house and came back out a few minutes later and all was well. Got mine on eBay too.

Anyone know if the remotes are specific to the TB?
I have an extra remote from the 2000 Escalade that I sold, and would like to program this to my TB.
Also, when you program a new remote, you have to program all others as well, correct?
