automatic door locks after you walk away

So, I am learning that the Mercedes I just buy, does not have the ability to automatically lock the doors as you walk away. Does anybody have any good ideas on how I could accomplish this? There isn't a feature on the car, is there an after market part I could buy that would do this?

I had a Cadillac before this that would automatically lock the doors after you walked away from the car.

Would love to know if anyone else had any ideas or experienced the same issue

Thank you so much!!!

All you have to do is press the door handle and it locks Never knew that there was a feature that automatically does it. Sounds like a good idea

I have the mirrors set to fold when the doors are locked and I simply lock the car from any one of the door handles. I like that you can confirm from a distance that it is locked by checking the mirrors.
