Very worrying.

In my opinion it's crazy if somebody feels the need to lock the car when leaving their child alone in it. If the child is old enough to be left alone then there's no need to lock it. Otherwise they shouldn't be left alone.....simple.

I can however understand the feature being useful if I was to leave the wife in the car alone in a dodgy neighbourhood her wanting the car locking. Current: RRS 2010 L320 Facelift 3.0 TD V6 HSE 5dr Alaska White

Gone:Mitsubishi L200 Raging bull edition MY 9/2009 2.5l DID Red

I leave the wife in mine, I do double lock it, just tell her not to move.
