question about the keyless entry

is our keyless entry an alarm system too in any way? if not, can u just add an alarm on to the factory keyless entry?
our keyless entry isn't really an alarm it just has a panic button (which would scare the **** out of someone if you catch them trying too break into your car lol) but you have too see them in order too scare them lol...as for the alarm i'm not too sure man you might not be able too because the alarm will control the door locks...
