Highway26

So, about a year ago I bought my 1997 4Runner. The guy who sold it to me stated in the ad that it had a factory alarm. When we were finalizing the deal I asked about a remote for the alarm and he said that he never had one and that you didn't need one because it automatically set when you locked the door with the key. I didn't really care at the time so I didn't think much of it. It has a security center light in the console, however it has never turned on and I can't really think of a good way to test it to see if I can set it off. Where would I look to see if I do in fact have an alarm? Thanks.
