With Keyless Open and Keyless Start, if equipped, you can lock and unlock doors, access the liftgate or trunk, and start your vehicle without removing your key fob from your pocket or bag, as long as it’s within range.

Here is information about general use, personalization settings, and what to do if the key fob loses battery or signal power.


When you approach the vehicle with the key fob within a three-foot range of the door, pressing the button on the driver’s door handle once will unlock the driver’s door; pressing it again within five seconds will unlock all doors.

If your vehicle is equipped with Keyless Open, it will be enabled upon vehicle delivery. If you don’t want this feature, you can disable it. 
To disable Keyless Open (not available on all vehicles):

  1. With the vehicle off, press and hold the Lock and Unlock buttons on the key fob for three seconds.
  2. The turn signal lamps will flash four times to indicate it’s disabled. Now to unlock the vehicle and disarm the alarm system, you will have to press the Unlock button on the key fob.

 To enable Keyless Open:

  1. With the vehicle off, press and hold the Lock and Unlock buttons on the key fob for three seconds.
  2. The turn signal lamps will flash two times to indicate Keyless Open is enabled.


  1. Touch Settings on the center display.
  2. Touch Vehicle.
  3. Select Remote Lock, Unlock, Start or Power Door Locks. Here are some features that can be customized:

Keyless Open — Enable/disable

Passive Locking — Automatically locks doors and trunk/liftgate after you turn off the vehicle, exit with the key fob and close all the doors

Passive Unlocking — Determine which doors unlock upon the first press of the button on the driver’s door

Remote Door Unlock — Changes which doors unlock when you use the key fob Unlock button

Remote Left in Vehicle Alert — Horn chirps if you accidentally leave your key fob in the vehicle after exiting

Remote Removed From Vehicle Alert — Horn chirps if the key fob is removed from the vehicle while it’s still on

Remote Unlock Light Feedback — Exterior lights flash when you unlock the vehicle with the key fob

Remote Lock Feedback — Exterior lights flash and horn sounds when you lock the vehicle with the key fob


To unlock the door, use the mechanical key inside the key fob:

  1. Press the small button on the side or back of the key fob while pulling out the side closest to the button. This will reveal the mechanical key inside.
  2. Find the small slot on the right side of the driver’s door handle.
  3. Insert the mechanical key into this slot and push upward all the way until the cover pops off.
  4. Remove the cover and insert the mechanical key into the cylinder underneath.
  5. Turn the key clockwise until it stops.
  6. Slowly turn the key counterclockwise while pulling the door handle to unlatch the door. When the door is opened, the door handle cover snaps back in place.

To start the vehicle:

  1. Inside the vehicle, find the key pocket and place the fob into it. The pocket location varies by vehicle model — check the Owner’s Manual.
  2. Start the car by pressing the brake pedal and pushing the Stop/Start button. NOTE: The first time you do this, you’ll see a Driver Information Center (DIC) message indicating no key fob is detected and prompting you to place the fob in the key pocket. When you try again while your key fob is in the key pocket, the vehicle will start.
