Doors don't unlock when you grab the handle

[nate39]

Hi, I have a 2020 Edge Titanium.  Everything has been working fine but of late.  The auto unlock no longer works unless you are at the driver's door.  We have the key on us, but it won't unlock any other door except the driver's door.  Does anyone know if this is something I can fix, thanks

From the 2020 Edge Workshop Manual with emphasis added…

 

Passive Entry (if equipped)

NOTE: To perform an accurate diagnosis of a concern, make sure the vehicle has a fully charged 12V battery and is in good condition when performing any electrical pinpoint tests. When the vehicle’s 12-volt battery is below a set threshold, certain features can be limited or become inoperative and lead to misdiagnosis.

 

Battery Load Shed

The main purpose of controlling electrical consumption with a load management strategy is to:

• Limit battery discharge
• Monitor the battery charge status

 

Because of the symptom your Edge is exhibiting – only the driver door passive unlock sensor is operative – you may want to have your Edge’s battery professionally checked at your neighborhood auto parts store, or by a specialty battery seller, or by your dealer’s Service department -- if you prefer.

 

Your Edge’s battery State Of Charge and/or Battery Voltage output may be invoking the vehicle’s Battery Load Shed strategy, resulting in the deactivation of the other three doors’ passive entry sensors.

 

An alternative course of action involves the following description…

 

Door Passive Entry

With a programmed passive key within 1 m (3.28 ft) outside a door, touch the lock or unlock sensor on the exterior door handle. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock button is located on the inside of the handle and the lock button is located on the outside top face of the handle. The driver front door passive entry feature either unlocks the driver door (if 2-Stage Unlock is enabled) or all four doors (if 2-Stage Unlock is disabled). The passive entry feature always locks all four doors when the lock button is touched. The remaining doors passive entry feature always locks or unlocks all four doors.

 

While that final sentence suggests otherwise, you may want to first try the following procedure, to attempt to toggle the 2-Stage Unlock enabled/disabled status -- to see if it makes any difference in the operation of driver door passive entry sensor upon all four doors…

 

Staged Unlock Programming - Activation

1. With the ignition in OFF, press the LOCK and UNLOCK buttons on the RKE transmitter simultaneously for 4 seconds.

2. The turn signals flash twice to indicate the mode change.

3. Repeat these steps to enable/disable the staged unlocking feature.

 

If this procedure makes no difference in the operation of the driver door passive unlock sensor, then have your Edge's battery tested to ensure it is not the root cause of your Edge's unlocking symptom.

 

If your Edge's battery tests as Good, then there are other more-technical diagnostic tests to assess what may be causing the unlocking issue -- which you may wish to undertake personally if you're technically capable and materially equipped, or, you may prefer to have your dealer's Service department conduct further diagnostic efforts and to correct the unlocking issue.

 

Please let us know the interim outcome and if you wish to receive additional guidance.

 

Good luck!
