sounds like the most probable cause, you can switch the interior scan sensors off, if it's going to be a regular problem until the windows are sorted,
with the ignition on, switch it off, on, and off again quickly,
the light on the lock button turns red for a few seconds to confirm it's been de-activated,
it is switched back on by turning the ignition on (not sure if it is just ignition on, or engine running) for about 30secs, so you might need to de-activate it every night,
You would be wise to confirm this with the Handbook
), as I'm going from memory, and you've already seen how well my brain works,
also this is how the 147 works, but I assume GT's are the same.
