I have a 2019 GLE 43 AMG, when the car is locked and I walk close to it, it detects the key so it unlocks which is great. But when I walk away from the car I noticed that the doors do not get locked automatically so was wondering how can I change the settings so it locks automatically when the key is not close to the car. Thank you

This is not a feature on your car. The door should unlock only if you touch the back part of the handle or pull the handle. It doesn't automatically lock when walk away and key is not near.

Ya that doesn't sound right, it shouldn't unlock either when you approach the vehicle only when you unlock it by putting your hand in the door handle as mentioned, if you are not the original owner, this vehicle might had equipped with some sort of aftermarket system.

It might feel as though it unlocks on approach but the actual unlocking occurs when you pulled on the handle.

Thank you all. Correct, when I pull the handle the door unlocks so that made me think that it senses the keys being close and was expected the car to lock automatically when the key is not nearby, I now realize this is not a feature of my car. How does the car know who is touching the handles if it is not sensing the keys?

It doesn't. To unlock the car, the key fob needs to be near the door handle you are touching. It uses proximity sensing. There are multiple antennas around the car, so it knows where the key fob is in relation to the car. The door will only unlock if the person with the fob is touching the inside of a door handle. The fob has to be within 1-2 feet of the handle you are touching.

Understooc. Thanks much. So it has proximity sensing for the unlock but does not offer proximity locking, correct?

superswiss

Correct.

A couple more details for you to help since this seems like your first MB with the smart key.

- To unlock, the key must be close to you on the side of the vehicle you are unlocking. When you touch the INSIDE of the handle, they vehicle will unlock. So if you have the key with you and you are on the driver's side, and person on the passenger side touches the inside of the handle, the vehicle will not unlock. Key must be on the same side.

- To lock the vehicle, the key must be on the same side of the vehicle (and also outside of the vehicle) and you touch the OUTSIDE of the door handle. There is a little indented rectangle. That is the touch sensor to lightly touch.

- Automatic locking, if you unlock the vehicle, but don't open the door, the vehicle will automatically relock within 3 mins (or something like that.)

- With the smart key, the vehicle will not allow you to lock the keys inside the car or the trunk.


Hope that helps!
