Jaguar XJ Key Replacement
Jaguar XJs have been on Dallas–Fort Worth roads since the 1996 era, and across 5 key generations this model has used 4 different key systems — transponder ignition key (no remote chip); transponder ignition key; remote-head / flip key; smart / proximity key. Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About XJ Keys
The table below is our verified key reference for the Jaguar XJ — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| XJ (X300/X308) | 1996–1998 | Transponder ignition key (no remote chip) | Megamos ID13 (Crypto) | FO21 (Tibbe) |
| XJ | 1998–2002 | Transponder ignition key | Megamos ID13 | FO21 (Tibbe) |
| XJ | 2003–2008 | Remote-head / flip key | Texas Crypto 4D60 (DST40) | FO21 (Tibbe) |
| XJ | 2009–2010 | Smart / proximity key | Hitag2 ID46 (NXP PCF7953A) | HU101 (emergency insert) |
| XJ (X351) | 2011–2017 | Smart / proximity key | HITAG-Pro ID49 (NXP PCF7953P) | HU101 (emergency insert) |
Security System & Immobilizer
Jaguar moved from Tibbe-key transponders through ID46 remote keys to today’s proximity smart keys — each era with its own parts and programming path.
On the XJ specifically, the immobilizer families we see are: Megamos ID13 (Crypto), Megamos ID13, Texas Crypto 4D60 (DST40), Hitag2 ID46 (NXP PCF7953A), HITAG-Pro ID49 (NXP PCF7953P). A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Jaguar XJ Key FAQ
I lost the only key to my XJ. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common XJ call.
My XJ is push-to-start. Can you really program that outside the dealer?
Yes. Late-model XJs (2011–2017) use a proximity smart key on the HITAG-Pro ID49 (NXP PCF7953P) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My XJ is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1996–1998 generation (transponder ignition key (no remote chip)), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my XJ in DFW?
