Summary Checklist

| Issue | Symptoms | DIY Difficulty | Solution | | :--- | :--- | :--- | :--- | | SOS Battery | "SOS Battery Low" message on dashboard. | High (Dashboard removal required) | Dealership advised. | | Key Fob Battery | "Key battery low" message; reduced range. | Low | Replace CR2032 yourself. | | Main Battery | Car won't start; clicking noises; "Economy Mode Active". | Medium | Replace (use AGM for Start-Stop models) and perform BMS reset. |

2. DIY Route (Cheap but Tricky)

• Part cost: ~$15–$30 (generic 3.7V 600mAh Li-ion with connector, or original Peugeot part #9812032980)
• Time: 45–90 minutes for a first-timer.
• Tools needed: Trim removal tools, T20 Torx, small flathead screwdriver, plastic prying tools.

Step-by-step reality check:

• Location: Under the overhead console (where the SOS buttons are near the rearview mirror). You must gently pry off the plastic housing – easy to break clips.
• Battery type: Often soldered or glued in. Many replacements require cutting wires and soldering or using a pre-wired battery with a JST connector (if you’re lucky).
• Reset needed: After replacement, the system often still shows the fault until you clear codes with a diagnostic tool (e.g., Diagbox or a high-end OBD2 scanner). Some cars auto-reset after a few ignition cycles; many don’t.

Cons & Warnings

• High risk of breaking trim clips.
• Soldering required in most cases – not plug-and-play.
• Some aftermarket batteries are too thick for the housing.
• If you mess up, the entire overhead unit can cost $200+ to replace.
