Security Light remains on
Car starts great, if I unlock the door through a open windowfrom the inside and don't use the key the alarm will sound and then go off if I use the key in the door.
There is no open door signs in the DIC and I checked the connection inside the truck lid, the one that has the white black connector to it.
Any idea why the "Security Light remains on in the dash?

If the vats module stops reading the key pellet while the engine is running then it'll disable itself. Car will still start & run but the security remains on.

Thanks for the reply Ted, the security light stays on from the time it starts till the time I shut the engine off, everytime. Do you think that can still be a Vats issue?
Is there anyway to test the Vats Module, I have a spare 95 SSEi parts car, is it something I can swap out, or should I look else where for another issue first?

System Check procedures -
To begin:
1. Put ignition switch in RUN position (engine NOT running)
2. Close front doors
3. Unbuckle seat belts
4. Set park brake off
"SECURITY" indicator should light for approximately five seconds.
if "Security" indicator remains on or does not operate properly:
Perform PASS-II Diagnostic System Check:
- Check for PCM Diagnostic Trouble Codes
- Attempt to start vehicle
- Note "Security System" indicator while cranking engine.
Did engine start?
No or Yes
I am assuming your engine starts so we will say "Yes"
Did the indicator turn on for approximately 5 seconds then turn off?
No or Yes
I am assuming "No"
Did the indicator stay "on" steady (vs. flashing, i assume)?
No or Yes
If no, then:
- check indicator "lamp"/bulb
- Check for an open circuit in CKT 264
- If, previous 2 are ok, then replace PASS-Key II Decoder Module
If yes, then:
Go to chart #1
Chart #1:
- Ignition switch "off"
- Disconnect the "Pass-Key II Decoder Module Connector"
- Ignition switch "on"
Does security indicator turn off?
No or Yes?
if "Yes", then, Pass-key II decoder module is not programmed or there is a system malfunction while the engine is running. Refer to Chart #4. (I can add this later if needed)
if "No", then:
Is vehicle equipped with Universal Theft Deterrent (UA6)
if No to UA6, repair short to ground in CKT 264
if Yes to UA6, then disconnect "Remote Function Actuator (RFA) Module Connector.
Does "Security" indicator turn off?
Yes, then replace RFA Module (I can look this up, too, if needed)
No, repair short to ground in CKT 264.
WARNING: If you are going to disconnect the PKII module connector as described in Chart #1, then, I need to post a warning. FSM says disable SIR (airbag) system to avoid accidental deployment. The PKII module is either "under" or "Near" the passenger side airag. If you are going to start disconnecting PKII and RFA stuff, please disconnect the SIR. I don't want to be responsible for any bonne damage/personal injuries.
