the liars at"original keyless" insisted in all their email response to me and my credit card co that their instructions would work. they advertise that they send programming inst with the remote.

"just hold unlock button and turn ignition on/off twice", and the module will go to program mode.

i offered to send them a video of me trying and never got further response.

i finally bit the bullet and went to a chevy dealer and paid $25 to verify that the remotes must be programmed by gm.

i hate con jobs and false advertizing, if it was made clear up front i might have bought but i was lied to, many times and dont like it.

never again.
