Then we'll send you the unlocked PCM after you've filled out the web form. When you receive the unlocked PCM, simply install the new unlocked PCM, and send back your core to Edge with the included return shipper label* and we handle everything else. 2019-2023 model year requires Gateway Bypass also included with purchase.
