Jaguar XJ All Keys Lost
★★★★★ 5-Star Rated — AJ Auto JLR Key Specialist
Losing all keys to a Jaguar XJ does not mean towing to a dealer. A mobile JLR specialist attends your location, gains access non-destructively, clears the vehicle’s immobiliser database, and programs new keys on site. The XJ in all three generations is fully supported for mobile all keys lost recovery across England and Wales.

What Happens on the Day
The specialist attends your location — home, workplace, or roadside. Entry is gained without damage to the vehicle. The diagnostic tool is connected to the OBD port and the immobiliser module is accessed. All existing key data is cleared, and new keys are enrolled to the vehicle. Both new keys are tested before the specialist leaves.
You should have your V5C logbook and photo ID available before the specialist arrives. Proof of ownership is required before any programming work begins.
How Long Does XJ All Keys Lost Take?
For X351 models, the process typically takes 60 to 90 minutes from arrival. For X350 and X358 models the process is sometimes quicker due to the simpler security architecture. If the vehicle battery is in poor condition, a support unit is connected before programming, which adds a small amount of time but ensures the process completes successfully on the first attempt.
What We See in Practice
XJ all keys lost situations often follow a period of the single remaining key developing intermittent faults. Owners who had two keys and lost one gradually accepted the risk of running on one, and then the second key failed or was misplaced. When we attend these callouts, the vehicle is almost always driveable right up to the point the last key failed. The process restores full function including push-button start and remote locking within the session, and the owner leaves with two working keys.
