Yes I did test the horn after I realized it was not chirping. The IROC has electric door locks, but you are right it does not have a fob to unlock the doors remotely. That was the old days when you had to actually walk up to the car insert the key then turn it to gain entry. I love modern technology.

I'll try setting it to lights only then lock and unlock it a few times. Then I'll set it back to lights and horn. Good idea thanks for the help.
