Jaguar XJ (X350/X358) Key Replacement (2003–2009)

The Jaguar XJ X350 and its facelifted successor, the X358, utilize a specific transponder system integrated into a traditional 4-button remote fob. Unlike many modern locksmiths who use generic tools, our mobile service employs dealer-level software to ensure that your new spare key or key replacement communicates perfectly with the vehicle’s PATS (Passive Anti-Theft System) and Body Control Module. This era of XJ was the first to feature the advanced all-aluminum monocoque, and its security electronics require precise synchronization to manage the central locking, alarm, and ignition functions across all production years from 2003 through to 2009.

If you are facing an all key lost emergency, we provide a complete on-site recovery solution that saves you from the expense of towing your vehicle to a main dealer. Our technicians can cut the physical high-security Tibbe or laser-cut blades and program the transponders directly at your roadside location. This avoids the typical 10-day wait for factory-ordered keys and ensures your classic-styled luxury saloon is back on the road the same day. Whether you need a simple battery-backed remote or a full security reset, AJ Auto Key Replacement delivers a high-quality, professional service tailored to the unique requirements of the X350 and X358 architecture.
