does W212 auto lock??
I would hate to unlock the car, put the key fob in the car, get out and shut the doors and have the car lock itself with the key fob inside. Again, not a P2 car.
The doors will lock if you leave the key inside the car. I did a little experiment. I put one key in the car and locked it with the other spare key. I unlocked the car with the spare key and didn't open any doors. The doors auto locked after 15 seconds with the original key still inside the vehicle.
On my S550 (Premium 3) and GL350 (Premium 2), both with keyless go, the doors will not lock if the key is inside the vehicle because the keys are constantly communicating with the Keyless Go tech inside the car via IR.

Keys : Hey, buddy how are you ?
Keyless go Tech : Fine , good to see you again
Keys : Thanks, can you please turn on the radio , let's have some fun
Keyless Go Tech : Cool, that's a good idea . How about New Country Hits
Keys : Well, I would like it if you have some House
Keyless Go Tech : Ok, let's go for it
and it continues lol

This feature prohibits accidental unlocking. Let's say the key is in your pocket and the button is pressed inadvertently. The car will re-lock itself as it assumes you did not want to unlock it since you did not open the door or trunk.
Engineered like no other Car in the World...




1. I tried putting the key in the trunk and close it, and it'll reopen automatically. I have a video to share too.
2. I CANNOT lock the door, with the key inside.
3. I CANNOT lock the doors, with engine running and keys outside the car(Ex: car in parking lot, engine still running, went to check the mailbox, which is in front of the car), still, I wanted to lock the car. The door handle lock button doesn't work, the 'Lock' button on the remote doesn't work either.
4. I turned off the car, 2 passengers got down out of 3, I LOCKED the car. The 3rd passenger got down and the alarm goes off for few seconds.
5. I'm done with my driving, did not lock the car, but closed all the door tightly, the doors DOESN'T LOCK AUTOMATICALLY. The 'Auto lock' feature in the MFD shows "Enabled".
I need help with #5

1. this is safety feature that's been on Mercedes (and many German cars) for years...it's essentially an aid that says "we make it virtually impossible for you to lock your keys inside the vehicle", thus requiring you to purposely press the lock button on the remote (or door handle, in case of Keyless Go) to lock the vehicle from the outside

3. this is safety feature that's been on Mercedes (and many German cars) for years...it's essentially an aid that says "we make it virtually impossible for you to lock the door but leave the engine running", i.e. you pull into the garage and forget to turn off the vehicle, but habitually lock the door...now you have a CO build-up that can kill you
4. passenger exiting the car while the doors are lock/alarm set = car armed, but someone breaking into the car...hence the alarm going off
5. 'Auto Lock' is a setting not for locking doors from the outside, but rather auto locking of the doors once you are in motion and have reached 15mph (or whatever the new velocity they use now)
Although, touching the door handle was so subtle and stylish, that would be nice.





In contrast, I believe the Lincolns and Teslas (and maybe a few other vehicles) will automatically lock once they sense you are xx feet from the vehicle, and will automatically unlock (and illuminate puddle lamps/welcome lights) once your presence is senses within a certain proximity.
Guess you can't have everything...

Even Acura's lock the door, after I walk away with the keys(MDX only or all cars after 2015, I guess; which came late to the party already).
I believe, since we have all the hardware, it is a matter of S/W upgrade. MB should include this feature in next COMMAND Firmware upgrade..!
