If I open my door with the remote everything is fine. If I use the key the alarm goes off!! Is this common? If it is it's dumb!![:@]

 

It's a design feature. If you lock the H3 with the remote you need to unlock it with the remote. Conversely, if you lock with the key you can unlock with key only. The remote, besides locking it, turns on the alarm. This is from the owner's manual:

Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system, do
the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will flash.
If the lock button on the remote keyless entry
transmitter is pressed, but a door is open,
the doors will lock, the lights may flash and the
horn may sound. Close the open door and
the alarm system will arm.
If a locked door is not opened using the remote
keyless entry transmitter, or by OnStarĀ®, the alarm
will go off. First, a pre-alarm will sound the horn
at reduced intensity for 10 seconds. Then, the front
turn signal lamps will flash for two minutes, and
the horn will sound for two minutes. The alarm will
then turn off to save battery power.
Starting the engine with the correct key will shut
off the pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not
activate if you lock the doors with the key,
the manual door lock, or power door lock switch.
