My 2003 KJ 2.8 CRD and its problems

[Geralt]

I think i found the problem.
While sitting in the Jeep, if I lock the doors with the remote, I see a small red LED flashing quickly on the dashboard.
This light turns off if I unlock the doors with the remote.When I lock the doors with the remote and open the door, the turn signals come on but not the siren.
I think the BCM I changed is premium because my vehicle does not have a siren and since it cannot find the siren module it blocks the start.
Is it possible to disable the alarm function?

I feel like it's going to start soon

On both of mine the alarm just sounds the horn & flashes the indicators.
The immobiliser on these is a nightmare because it's on the PCI BUS, the ECU sends a token on the BUS and won't move onto the next step without receiving one back, so it's a very hard thing to bypass.
The SKIM module is coded to the ECU and whatever keys it was initially programmed to, a good auto locksmith might be able to do something with it.
