More than 2 Key FOBs Programming

[02-Z71-TX]

I lost one of my FOBs and had it replaced, I found the lost one, is there anyway to have all three programed? The dealer does not know. Right now the lost one does not work, only the replacement and my spare (originally the truck came with two).

First off that dealer is an idiot

next There is a way to do it im not sure if it is the same for my blazer as it is for the silverado but its worth a try .

 

You can program I think up to 4 per vehicle

make sure all the numbers match on the back of the transmitter

 

1. Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.

2. Hold down the key FOB lock and unlock buttons for 15 seconds . The locks will again cycle once.

3. Repeat step #2 for each additional key FOB.

4. Turn the ignition on to exit the key FOB programming mode. Programming is now complete.

[Taaaaaaahoe?]

Sounds about right!
