ℹ️ What is a Prox Fobik Key? The Prox Fobik (Proximity Flip OBD Integrated Key) combines a proximity/keyless entry sensor with the traditional Fobik flip key design. Unlike the standard Fobik, the Prox Fobik also supports passive entry — the vehicle can detect the key's presence and unlock automatically. The 6+1 button layout typically includes lock, unlock, boot, remote start, panic, and an additional proximity-related function, plus the hidden blade release. Verify your current key is a Prox Fobik style before ordering.
⚠️ Diagnostic Programming Required: This Prox Fobik key must be programmed using a diagnostic scan tool by a qualified automotive locksmith or mechanic with FCA/Stellantis-compatible equipment. It cannot be self-programmed. Please confirm your locksmith has the correct equipment before purchasing.
