This way it has the time to open the doors if needed when turning ignition off and then do not draw any current.
This way no worries about the battery if the car is not driven enough.
I've been using this since a few months and some track days without an issue  |
Brilliant idea!
Oh wait, you can unlock the doors when the ignition is off? I could have sworn I tried this without success. I am using this for door unlock: 750#4005301100400000
I guess I need to test this again. Or maybe there is some sort of grace period or you are sending the command before the key has been completely removed. It would be cool if you could unlock the car without the key in the ignition. Then you could do some sort of BLE proxy unlock/lock.
