No idea what brand it is. Called the PO, he said it came that way from the dealer, so who knows????

I can hear the relay clicking as soon as I open the door. The siren was previously disabled.

There is a valet button, that had been working, but isn't any longer.

I will try that trick with the key.

I believe that the brain is under the dash, but it's not clear where it is.

Thanks for your advice!
