Did you see if the siren actually goes off when a door is opened, if the panic mode works, or if the tilt and motion sensors work? If the car was previously coded to flash the blinkers when locked/unlocked, the siren will beep when locked/unlocked too... but the alarm itself won't necessarily be activated.

Well, I did try to remove the connection on the battery and it went off.
On the other hand, I though it would also beep while locking the doors but it doesn't...

The hood (and trunk and all doors) has to be closed for it to beep when locking. The battery doesn't mean anything - that's just a function hardwired into the siren if I remember correctly (if it loses power, it defaults to its internal battery reserve and just whales)
