Remote opening windows

[Spaghetti]

Hi everyone, 

So I hear I can open my windows using my key on my 2011 Astra Gtc  and I tried it but it didn't work, I read online you need to select the option on remote locking but the option isn't there?

Does this mean I can't do it? Or am I looking/doing something wrong?

Not really a big deal I just like the novelty of it haha

The usual method is to hold down the unlock button until the windows drop.

Possibly try this with the ignition switched on to initiate this feature to the vehicle
