#8 of 13 Suburban doors lock by themselves by ptownbubba Sep 03, 2008 (9:31 am)
Our 07 Burb locked it's doors the other day, we got out at a friend's house, left the keys in ignition,, and after a few hours, the doors were all locked. It has never done this while parked in the garage all night, without the keys in ignition,, could it be Onstar detects keys in ignition,,, and does it it to protect vehicle form crooks ?

Replying to: ptownbubba (Sep 03, 2008 9:31 am) The vehicle has a BCM (Body Control Module), which is a computer that manages doors/windows/lights/locks/etc. Nothing really to do with whether you have OnStar or not.   I didn't realize it would do that under the circumstances of leaving the keys in the ignition (since I never leave keys in the ignition), but seems totally reasonable. Most newer vehicles will lock the doors automatically after a short period of time, after it receives an 'unlock' command from the key-fob, followed by 'not' detecting a door opening.

So,,,,, probably nothing wrong,,, just better not leave keys in vehicle,,,, the BCM must get nervous seeing those keys hangin' there, and the owner not around. Sort of a "pain" when you live in the sticks where keys in vehicles is pretty common.   Thanks for the reply,,,,   greg Replies to this message: kiawah (Sep 03, 2008 10:30 am)

Replying to: ptownbubba (Sep 03, 2008 10:25 am) I'll actually do a test for you, I will go put the keys in my 07LTZ which is in the garage, and lets see it it does the same.

ok,,,, cool,,, ya' know what,, I will do the same here,,, see what happens,,,will post results tomorrow.   Of course you know if it does not lock the doors, this time,,,,, that will be a head scratcher.    Pulled into drive,,,,, opened both front doors, to get out, opened back door to get some stuff out,, took cooler out of rear hatch; keys were left in ignition,,,, windows up,,,, doors unlocked,,,, that is how it was the other day.
