What SW30 does
- SW30 adds any key type suitable for the vehicle over OBD, including OEM and non-OEM keys. On locked EVA2, it requires two working keys detected by the vehicle or active service mode. It adds keys without erasing existing keys or unlocking the RFA.
- BCM support: L8B2, R8E2 and M8E2. Confirm the BCM type and satisfy the two-key or active-service-mode requirement before using SW30.
- This adds new keys into the locked RFA & BCM. It does not delete old keys — keys cannot be erased while the RFA remains locked. After successful SW40 unlock on a supported EVA2 vehicle, keys can be erased without replacing the RFA. If a replacement RFA is needed, program it with SW28, then program keys again. Follow the applicable vehicle and telematics prerequisites; BCM lock status is separate.
How the job goes
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.
SW30 eligibility: After checking, proceed with add-key over OBD only when the vehicle detects two working keys or service mode is active. The service-mode alternative does not remove the pre-function Check Keys check.
- 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. Alternatively, the customer can enable service mode through the InControl app for SW30 add-key over OBD.
- Run Add Keys in Key Learning.
- Add the new key on the Lock50, then place it on the seat to finish when the Lock50 JLR software instructs you.
Only 1 key? Use the SW36 duplicator to prepare another working key, then use Check Keys to confirm that the vehicle detects two keys together. No keys at all? Prepare keys with SW36 on HW13 / HW14, then run Check Keys with both inside the car. Proceed with SW30 only when two keys are detected, or use active service mode. If the client has the app and can enable service mode, any key type suitable for the vehicle can be added over OBD into the locked RFA without swapping any modules.
Proven on the bench
- Defender 2024 Activity Key programming with Lock50 HW04 in a locked RFA & BCM vehicle.
- C-package demo — 2023 Range Rover Sport spare OEM key, no modules changed.
- All-keys-lost or spare keys use the same process — add OEM keys in a locked RFA + BCM, no parts, in under 10 minutes.
Hardware, cars and years
- Runs on HW04 — all packages A, A+, B, C and C+ (uses HW03-E DoIP Ethernet cable for DoIP models).
- Cars: EVA2 platform Jaguar and Land Rover 2021 to 2025+ with locked RFA + locked BCM (L8B2 / R8E2 / M8E2).

| SW28 | New RFA programming when the BCM is locked — used when a replacement RFA is required. Successful SW40 unlock of a supported existing EVA2 RFA can permit erasure without replacement. |
| SW36 | Key duplicator — copy a key when RFA and BCM are locked, no RFA change. |
| SW29 | Add or remove keys when the RFA and BCM are unlocked. |
