I have an 03 Chevy Avalanche w/ an alarm remote start running through an XK01. Here's my problem. The factory alarm keeps arming itself and locking the doors 15-20 seconds after I unlock the truck.
I had the alarm hooked up with locks and door triggers while my XK01 was being shipped to me and I had no problems what so ever. Now the truck keeps arming the factory security.
Does GM have passive locking/arming as an option in the Chevy Avalanche? And if so, how do I toggle it?
Also, could it have something to do with the firmware on my XK01?

Update.
It turns out the doors only lock themselves if I unlock the truck. If I run the truck and then shut it off, they don't automatically lock.
So here's the cycle of events:
Upon unlock (w. XK01 plugged in): Doors lock themselves at 15 secs.
          then the truck arms the factory alarm and cycles the locks at 20 secs.
(w. XK01 unplugged, the problem ceases. I'm going to try a replacement unit tomorrow)

What kind of alarm/remote start?
Sounds like it's something from the alarm, not the XK01. I've never seen the XK01 (or any other bypass module) do that.
Hondas, Toyotas, and I think some/all Nissans have the feature you're describing----if you unlock the door with the remote, but then fail to open the door and get in, the car relocks itself.
Maybe your aftermarket system is trying to copy that and give you the same feature, whether you want it or not.
See if there's a "relock" or some kind of similar feature maybe you can turn off in programming for your alarm..

As I posted above. I have run just the alarm fir quite some time on its own. Both before and after I installed the xk01. The problem only occurs when the xk01 is plugged in.
On a side note. Does the window roll up feature work on all chevts w/ pwr windows?

Update:
I swapped out the XK01 with a new one and got the same issue.
With the XK01 plugged in, the factory alarm arms itself in 15 seconds.
Without the XK01 plugged in, there's no issue.
Are there any other bypasses that work well with GM's?

The XK01 isn't the problem. The problem is with the starter/alarm that is controlling it. The alarm is activating the lock input of the XK01 module either by a fault or becasue it is programmed to do so. Disconnect the XK01 door lock input and see what happens. The XK01 is designed to rearm the alarm after the remote starter is shut down to protect the vehicle.

I should have stated this before but I have the locks are wired straight to the alarm, not the XK01. The XK01 is locking and arming the car on its own (since the alarm doesnt lock on its own when the XK01 is unplugged). The XK01 lock inputs have not been connected since the early stages of me diagnosing the problem to eleminate them as a variable. Do I need to do something with the orange wire on the XK01 harness to stop this problem?

Sorry to butt in but could there be a key sense issue here? I thought it was only Euro alarm units that had that awful nuisance "causal re-arming" feature.

I actually figured it out. My status output line was programmed to factory disarm instead of status, so it was pulsing (-) upon unlock on the XK01's grounded when running line (brown wire), which made the XK01 think the car just got done remote starting, so it re-armed the factory alarm.
