Auto lock

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?

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!

Thanks much for your helpful reply, really good info. Let's say I leave the car after parking it and go away from the car, will the doors be locked after 3 min?

nope unless you turn on autolock and not unlock any door or tailgate beforehand.

That auto lock feature is only there so it locks if you accidentally pressed unlock.

No it will stay unlocked. You have to close the door, lock it, and then unlock it. Then it will re-lock itself. Like the user before me wrote, it's helpful off you hit unlock and then forget that you unlocked it and walk away from your vehicle.

interesting, thanks much. Then I guess when someone unlocks their car, they usually geti in it and drive hoping when they are out of their car, the car locks itself. I wish they add tyat feature soon. I am waiting for some very distinct body changes so I can have an excuse to buy a new one.

I don't they will be changing it. Mercedes more than any other brand I know puts a lot of thought into the holistic user experience. The smart key feature with the lock has been around since I can remember...2008 when I starting shopping for my first MB.

As mentioned, MB will never implement auto lock. If you have Mercedes Me and keep it running in the background, eventually it might send a toast notification to alert you car has kept unlocked.

If you really want it to auto lock, there are aftermarket solutions. Some German competitors like BMW also have auto lock when walking away when enabled.

Does the 2025 GLE 450 support the walk away Auto lock feature? Gemini says yes with video but I can't find the feature on the center display menu. Is this feature available on any other MB models?

My 2020 BMW has this handy feature and I never have any incident of locking the key fob inside. This confuses me quite a bit when walking away from the GLE without locking it, since I get so used to the bimmer smartness.

Walk-away locking is a great feature that many manufacturers have implemented into their offerings with various degrees of success. I may be off, but I remember GM had this feature in the 90's in the 'Vette, so it's not a new and never before heard of technology.
The technology is very convenient and easy to implement, not sure why the Mercedes engineers think this is not a feature that should be implemented on the brand's vehicles. At this point, it's likely just software programming, since all the hardware is there.

Download the MB app and lock or unlock your car from your phone, anytime you want.
