I have a question about my remote,I have a 2000 Blazer,when I lock the doors with the remote ,the lights don't flash,but when I unlock they do,any suggestions?

 

Features like that can be changed with a Tech2 scan tool (dealer). I think that some of the newer (2002+ IIRC) could be modified through a special sequence of button pushes both on the FOB and inside the truck, but not the older ones.

 

Thanks swartlkk, I was hoping it was something I could do,the dealer will probrably charge me an arm and a leg for something so simple lol.
