Programming a new key for your Alfa Romeo Stelvio (2018-2023) can be a straightforward process if you know where to locate the bypass connection. In this guide, we’ll walk you through the steps to program a key without removing the instrument cluster, using a FCA 12+8 bypass cable with 2-pin.
Tools You’ll Need
Xhorse Mini OBD tool (or a compatible key programming device)
FCA bypass cable (with 2 pins, black and red wires)
Basic prying tools
The Mini OBD tool is used to read the vehicle’s pin code and program the new key. The key programming process involves placing the new key in the bottom section of the center armrest and pressing the unlock button.
NOTE: Xhorse FCA bypass cable does not have 2-pin. You can use xtool/obdstar FCA 12+8 bypass cables or Lonsdor L-JCD Cable.

Locating the Bypass Cable
Unlike some methods that require removing the instrument cluster to access the bypass cable, there’s a simpler approach. The bypass cable is located behind a cover near the center console, which can be easily pried off. Follow these steps:
Remove the Cover: Locate the cover near the center console (exact location may vary slightly by model year). Gently pry it off using a trim tool or similar instrument. This cover is the only component you need to remove, making this method less invasive than disassembling the dashboard or cluster.
Identify the Bypass Cable: Inside, you’ll find several cables. Look for the specific 2-pin bypass cable, which may be tucked away but can be pulled out by hand. Be cautious not to confuse it with other cables, such as a blue one that may be present. The correct cable has brown and green wires.
Connecting the Bypass Cable
Once you’ve located the bypass cable, connecting it is simple:
This straightforward connection allows the diagnostic tool to communicate with the vehicle’s system for key programming.
Programming the Key
With the bypass cable connected, proceed with the key programming:
Place the new key in the bottom section of the center armrest.
Follow the tool’s prompts, which typically involve pressing the unlock button on the key.
Reassembling the Vehicle
After successfully programming the key, reassemble the vehicle:
Reattach the Cover: Position the cover by aligning the top first, then gently press the bottom until it clicks into place. There’s no need to remove or disassemble additional components, as some methods suggest.
Verify Functionality: Test the new key to ensure it works correctly with the vehicle’s locks and ignition.
Why This Method Works
This approach is efficient because it minimizes disassembly, saving time and reducing the risk of damaging interior components. By accessing the bypass cable through the center console cover, you avoid the complex process of removing the instrument cluster. The brown-and-green wire connection is easy to identify and connect, making it accessible even for those with limited automotive experience.
Conclusion
Programming a key for a 2018-2023 Alfa Romeo Stelvio doesn’t have to be complicated. By locating the bypass cable behind the center console cover and using a 2-pin bypass cable with a diagnostic tool, you can complete the process quickly and efficiently. Just remember: black on brown, red on green, and you’re good to go. This method ensures a clean, professional finish without unnecessary disassembly, leaving your Stelvio ready for the road.
