I’m wondering if there’s a way to unlock all doors without the remote? My old Acura tlx had the ability to double pull the door handle to unlock all 4 doors.

 

Touch the inside of one of the exterior handles EXCEPT the driver’s door. So when you approach the driver’s door, first do that to the rear driver’s side door and both you and any passengers can get into a fully unlocked car. Same for the other two non-driver’s doors. You do need a remote in your pocket. Obviously you know that doing this to the driver’s door only unlocks the driver’s door. I do this, first touch the inside of the rear door unlocking handle, all the time, when I have a passenger or passengers.

 

Prior gen and most other models you just program it through the menu.

 

Same with my Acura. The 3 passenger doors unlock all doors.

 

You can change this in the settings menu. I believe it's under Vehicle Customize, Door Control. You can set this to "driver door only" or "all doors unlock" when you press the driver's door handle.

 

I think my way is safer. If it’s just the driver, then there’s no need for the passenger doors to unlock. And when you do have 1 or more passengers, a quick, easy swipe of the rear passenger driver’s door unlock, on the way to getting into the driver’s door, lets them in. It keeps the choice to “optional, on the fly”.

 

I have our cars set up that way. Driver’s door only. Especially on my wife’s car. Then as you say, a swipe of the rear handle for passengers.
However, I have a 2 door. That means any passenger has to endure the indignity of waiting while I open my door and hit the switch.

 

Our '21 Subaru Crosstrek is like that, sort of. It's a four door, but the rear doors don't have the unlock sensors. In all other ways, the tech is the same as Lexus. Anyway, when there is a passenger I generally "become a gentleman" and open the door for that person. I can only think of one time in two years of ownership where there was more than 1 passenger and I think I did the heavy lifting of reaching into my pocket to push the unlock FOB button, twice, to fully unlock the car.

 

Latest Lexi have added a feature to unlock all doors from the driver's door handle -
The initial response when you reach through the handle unlocks just the drivers door as before,
leave your hand inside the driver's door handle for a couple of seconds and the guest doors will unlock.

Related feature for all years & models - when you first touch the outside "dimple" to lock all doors
you can confirm the action by immediately reaching into the handle and give it a tug. For the first 5 seconds
after locking it will not unlock. This is handy if your are in a noisy environment and don't hear the locking chirp.

 

Son of a gun! Now THIS is why this forum is great. No one would have found that in the 500+ page manual! I tested this and you are right! I wonder if this works the same way in our Subaru? EDIT:NOPE! I wonder if I had this in my 2020RX and never knew it.

The "five second rule" that you mentioned I DID know about.

 

Neither of those tricks work on my Merc. I confirm by the mirrors folded in.

 

"Neither of those tricks work on my Merc."

There's just something about a Mercury.
