My ex girlfriend had a factory installed honda remote strt on her vehicle. It was activated by hitting the lock button two times in succession. Some vehicles use a combination of the lock-unlock buttons. try using some combinations on the remote, many "oem" remote starts are installed by aftermarket installers so who knows what they did as a start function, it could also have been changed by the previous owner.
