Confirmed: program Jeep Compass 2019 with original key 4A by using OBDSTAR X300 DP Plus and FCA 12+8 obdstar cable. And you can try xhorse proximity remote to program, it will work unlike the pacifica 4A china key.
Image 1: after entering “Chrysler / Dodge” of OBDSTAR, you will see the message “Place the top end of the proximity key close to the start button and pres the start button to keep it still while pressing the unlock button twice.”.
Image 2: This is FCA 12+8 Universal Adapter For OBDSTAR X300 DP / X300 DP Plus.
Image 3: FCA 12+8 cable is supposed to insert into the DLC of Jeep Compass 2019 shown as above.
