Key Alarm Sounding w/ No Key Inserted

[Sy229]

So Mona comes in from the garage and says the Typhoon is making a weird noise. I hadn't driven it in weeks, so I'm thinking it must be something else in the garage. Hmm, it is the Ty. Open the door to hear a very weak, intermittent buzzing sound near the steering column. It appears to be a short in the 'you-left-your-key-in-the-ignition' alarm, as it quits when I insert the key.
Drove the truck around hoping it would quit when I got back. Nope, there it goes again a few minutes after shutting down.
This key cylinder has also given me trouble on two previous occasions, not wanting to let go of the key once I shut the truck off.
I'm thinking I should just swap out the cylinder. Anyone else experience something similar?

Are you sure it's not the "lights on" reminder? Cause that would quit when you put the key in too....

You're right, that's a possibility too. With the buzzer sounding, I jiggled (tech term) the light rocker switches and the buzzing stopped...temporarily. I'm going to take a look at the electrical diagrams for the alarm and then attempt to isolate/troubleshoot the problem circuit.

Light switches could be wearing out. When my dash lights refused to work and my headlights wouldn't stay on, a new switch solved the issue. Cheap and easy fix.
