Plug In & Connect
At the car, plug your J2534 device into the OBD port, power the vehicle with a battery support charger, and start a FlexiHub session so we can connect.

We Recover It Live
We run the manufacturer software from our end and recover your module while you watch. Most sessions finish the same day — no shipping, no downtime.

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓'Smart Key Not Found' / 'Unable to find smart key' no-start after a battery event
- ✓No-crank / no-start caused by CJB immobilizer corruption
- ✓Central locking dead after disconnecting or replacing the battery
- ✓Scrambled or missing VIN (??????????) on a diagnostic scan
- ✓Washer/wiper, lighting, or comfort faults stemming from the corrupted CJB
Won't fix:
- ✗Physically water-damaged / severely corroded CJBs that need bench repair or module replacement (deep EEPROM corruption may require the unit out)
- ✗The underlying washer-pump water leak — fix the leaking pump/wiring or it recurs
- ✗A genuinely failed/dead battery, alternator, or bad grounds (replace the battery + clean grounds first)
- ✗Mechanical key-fob faults or a dead fob coin-cell
How the Remote Session Works
We confirm compatibility and the steps with you before the session.
This is a REMOTE service — you keep the car. After payment we schedule the session: you plug your J2534 device into the OBD port, start a FlexiHub USB-over-network session, and we run Jaguar SDD/Pathfinder from our end to recover the CJB. We assess recoverability first and tell you honestly before we commit.
What you need for the session
- A JLR-capable J2534 pass-thru device (JLR VCI / DA-Dongle / Mongoose-class) on the OBD-II port
- A stable, low-latency internet connection — wired/Ethernet strongly preferred
- The vehicle on-site with its smart key(s)
- A battery support charger / power supply holding steady voltage for the whole session
- A Windows laptop at the car able to run FlexiHub / the USB-over-network client
Remote — no shipping
You keep the car. Pay, then we schedule the FlexiHub session and walk you through it. Questions? Text us first to confirm your car is recoverable.
