i have a 2003 suburan and a 1999 tahoe is there any way that i can use 1 remote to lock and unlock both. :banghead: i tried.

you can have a dealership change the frequency code or whatever it's called so they both use the same one. but you're still going to have two keys to start them, unless you want to have all the locks replaced on them. and that's only if you can get hold of two sets of locks using the same key. usually there's only one set put cutting. (cutting as in, the cut on the key)
