Auto Relock Enable is a lower-risk, convenience-oriented change for 2015–2026 Ford F-150 trucks, applied with FORScan over an OBD-II adapter. Truck automatically relocks if not opened after unlocking. It is fully reversible and typically takes about 5 minutes to write once your worksheet is in hand.
The change touches the Body Control Module (BCM), and your F-Config worksheet lists all 3 as-built code rows with the module, address, and target value. Each row includes a blank for your original value so you can back up before writing changes and roll back later. Security feature - forgot to open door? Truck relocks automatically.

The DIY process from start to finish — backup-first and, where possible, reversible.
Before changing anything, use FORScan to read and record the current value of each of the 3 rows in the Body Control Module (BCM). Your worksheet leaves a blank beside every row for exactly this.
Enter the 3 target rows from your worksheet one at a time. Most owners finish Auto Relock Enable in about 5 minutes with a laptop and a FORScan-compatible OBD-II adapter.
Turn the key off and back on, then confirm the change behaves as expected before moving on. If anything looks off, stop and compare against the originals you recorded.
Because Auto Relock Enable is fully reversible, you can put every original value back later and return to stock whenever you want.
