Option 535 - Remote Controlled Alarm

[Ray]

My car is a 1999 and I still have the window sticker to the car (I'm recent 2nd owner):

I have the disabler (I think). The red LED in the front of the windshield does not flash and when I lock the car (with the key) AND there is no horn sound so no error?

I'm now thinking 3 things: 1) I dont have the remote option because my keys came with lights. 2) I don't have an alarm but maybe just the disabler? and 3) The LED is burned out?

Question: Can I get the remote alarm option installed still? (Yeah, but how much???)

Thanks!
