Description

Lock50 SW40 • HW04-C & C+ Function

Lock50 SW40 — Unlock a Locked EVA2 RFA — L8B2 / M8E2 / R8E2 / S8E2 BCM

Unlock locked keyless RFA modules on modern EVA2 systems (2021–2026+). Restores full key programming, Security Key Erase, and diagnostic functions.

🚗 JLR EVA2 2021 to 2026+ 🔒 L8B2 / M8E2 / R8E2 / S8E2 BCM 🔑 Check Keys first; Phase 4 Plus needs 2 keys ⚠ Telematics Phase 4 Plus Guard ✅ Full RFA Functions Restored

What SW40 Does

Unlocks a locked RFA module on EVA2 platforms with L8B2, M8E2, R8E2, or S8E2 BCM types, found in Jaguar and Land Rover vehicles 2021 and newer.
After unlocking, all standard functions become available: firmware flashing and updating, adding / removing keys, Security Key Erase, and replacing the RFA.

Unlocking Rules & Connection Procedures

Check Keys before starting

Before starting SW30 or SW40, run RFA Check Keys in the vehicle. Complete this check before running the function; a desktop key-reader result is not a substitute.

Reader check versus vehicle detection: Reading a key on the Lock50 reader checks the key itself; it does not prove that the vehicle can detect it. RFA Check Keys checks which keys the vehicle actually detects. When checking for two keys, put both keys inside the car at the same time and confirm that Check Keys detects two, rather than relying on stored key slots or possession of two fobs.

If Check Keys disconnects: A communication loss does not automatically mean a faulty key. Vehicle or dashboard sleep is one possible cause, not a confirmed diagnosis. Follow the software ignition instructions, restore communication and rerun Check Keys before relying on the result.

SW40 eligibility: Direct OBD unlocking requires two detected keys. With Telematics Phase 4 Plus, two keys must be detected together for either OBD or CAN-wires unlocking. If Check Keys cannot see two keys, do not run SW40 on Phase 4 Plus; service mode is not a substitute. The supported non-Phase-4-Plus CAN route retains its existing conditions.

✅ Scenario A: Customer Has 2 Working Keys — Direct OBD Unlock

Place both keys inside the car at the same time and run RFA Check Keys. Confirm that the vehicle detects two keys; owning two fobs or seeing two stored key slots is not enough. When two keys are detected on a supported EVA2 vehicle, use SW40 with the HW03-E DoIP Cable for direct OBD unlocking.

Connect the HW03-E OBD DoIP Cable to the vehicle OBD port.
Follow the software ignition instructions and confirm two detected keys in RFA Check Keys with both keys inside the car together.
Launch Lock50 Software → Special Functions → SW40 Unlock EVA2 RFA.
Execute OBD unlock. No physical access to the RFA or adapter cables required.

🔑 Scenario B: Supported Non-Phase-4-Plus EVA2 Only — 0/1-Key CAN Route

The existing 0/1-key CAN-wires route applies only to supported EVA2 vehicles without Telematics Phase 4 Plus; it does not bypass the Phase 4 Plus two-key requirement. Check the TCU type before using the adapter instructions below. If it is Phase 4 Plus and Check Keys cannot see two keys, do not attempt SW40 by either connection method.

Connect the HW03-E DoIP Cable to the vehicle OBD-II port.
Scan the car in Lock50 software to read vehicle VIN, platform architecture, and module identification.
Then connect the HW03-C Adapter (using the F1 and M1 connectors) directly to the RFA module (or use HW03-B for direct CAN2 connection at the door module).
On a supported non-Phase-4-Plus vehicle, follow the SW40 CAN-connection instructions. HW03-C does not bypass the Phase 4 Plus two-key requirement.
Once unlocked, execute Security Key Erase to clear lost keys, then program new Lock50 Fixed ID keys (HW15 to HW26).

⚠ Scenario C: Telematics Phase 4 Plus (Latest System) — Strict 2 Keys Requirement

On late EVA2 vehicles, always inspect the TCU / Telematics configuration in Lock50 software:

        RFA Utils / Central Configuration → Telematics Type: Telematics Phase 4 Plus
      

Confirm the actual Telematics Phase 4 Plus TCU type in RFA Utils; do not determine it from model year alone.
Place both keys inside the car at the same time and run RFA Check Keys. Confirm that the vehicle detects two keys; owning two fobs or seeing two stored key slots is not enough.
Telematics Phase 4 Plus: SW40 cannot unlock the RFA over OBD or CAN wires unless Check Keys detects two keys together inside the car. Run Check Keys before choosing the unlock route. Service mode is an alternative for SW30 add-key, not a substitute for this SW40 two-key requirement.

🛠 The Critical K8D2 Architecture Pairing Rule (EVA2 vs Non-EVA2)

A K8D2 RFA module is ONLY an EVA2 system when paired with a Body Control Module (BCM) of type L8B2, M8E2, R8E2, or S8E2.

If an earlier vehicle has a K8D2 RFA paired with a JPLA BCM, it is an early non-EVA2 architecture. On this non-EVA2 variant, OBD software unlocking with SW40 is not possible — you must either duplicate keys directly using SW36 with the HW03-C adapter, or replace the module with an unlocked / virgin RFA.

After Unlocking: Operations & Key Options

You can erase lost/stolen keys and program new keys into the cleared slots.
Or simply add new keys without erasing existing working keys.
Program new Lock50 Fixed ID keys (HW15 to HW26) directly over OBD.
Execute firmware flashing, updates, or module adaptation.

⚠ Important BCM Gate Note: SW40 unlocks the RFA, but does not unlock the BCM. To replace an RFA with a locked BCM, use the “Replace RFA with locked BCM” special function — see SW28. It works on a fully functional vehicle with original configuration without unauthorized module swaps.

Who Can Use SW40 — Package Gating

HW04-C+ — SW40 is built in. Unlimited use, lifetime access, no tokens ever (HW04-C+ kit).
HW04-C — not included by default. Two options: buy a per-job SW40 token (£300 + VAT per RFA unlock), or upgrade HW04-C to HW04-C+ for unlimited use.
Pay As You Use, HW04-A and HW04-B — SW40 is NOT available and tokens cannot be bought on these tiers. You must be on HW04-C (token) or HW04-C+ (included). Upgrade first: PAYG to C, A to C, B to C, or straight to C+ (PAYG to C+, A to C+, B to C+).
