My MY2016 SDV8 AB both rear doors now cannot be opened from the inside, this is something new as it worked fine for the last few years.

I haven't changed anything, any ideas anyone please?

Check you have not activated the rear window lock switch on the drivers door that also activates the electronic child locks. 2013 L405 AB 4.4SDV8 Luxor/Ivory, 2007 Vogue TDV8 Epson Green/Sand, 2008 Vogue TDV8 Buckingham Blue/Sand, 2003 Vogue 4.4 LPG Epsom Green/Sage, 1998 Vogue SE 4.6 LPG Epsom Green/Cream

As above, that’s what I did, took me an age to figure bit out 🥴

My right rear doesn’t open at times. Child lock defaults to on which is incorrect.

Cycling the child lock button on the drivers door will open it. I have ordered a used replacement door latch assembly to rectify the problem. Dan. 🇨🇦 2013 L405 5.0 SCV8

Yes, rear window door locks had been activated. I thought that was only for the windows but obviously not.

Thanks everyone. Forum to the rescue, again.

Every day's a schooldays with a 405. First time we had freinds in the back the child locks were on. Quick ref to the handbook and all sorted by the drivers door controls. 2017 5.0 Autobiography Supercharged
