Thanks for all your weird and crazy suggestion guys. Had a giggle reading through them lol.

I checked all my papers and manuals and discovered that I do have an OEM alarm system installed and not just a remote key less entry system.

That button is indeed OEM/Factory

It is used to activate the Valet mode of the alarm and also used for other random alarm diagnostics such as reactivating the last set of alarm codes to go off, etc.

Thanks again for all your help guys

no ur manuals wrong, its VTEC override.... for people new to VTEC
Valet system... pfft
