I know this is probably a little out of date but we had same question with ours as we leave a dog in it. apparently the easy answer is to lock the drivers door with the key rather than the remote, this engages the dead locks but not the alarm, you can then unlock with the remote without the alarm activating. this works on the 2013 XV so imagine other will be the same.
Just thought I'd throw this up in case anyone else needed this answer in the future
Cheers
