The specialized JLR key programming solution for the modern automotive locksmith. JET-LS (Locksmith) by SX-Tool is engineered specifically to handle key programming and ‘All Keys Lost' scenarios on the latest JLR vehicles (2018+) that use secure DOIP/UDS architecture.
Product Description: The Solution for “Unprogrammable” Modern JLR Keys
As a professional locksmith, you know the frustration: a customer with a 2020 Range Rover has lost all their keys, and your standard key programming tools fail, blocked by the vehicle's advanced DOIP/UDS security. This is a common and growing problem that leads to lost jobs and referring customers to the expensive main dealer.
JET-LS (Locksmith) is the answer. This is a purpose-built software tool that gives you the power to program keys for these highly secured vehicles, including complete ‘All Keys Lost' (AKL) situations, without needing an online dealer account.
Empower Your Locksmith Business
For independent auto locksmiths offering services like car key replacement in Singapore, London, Sydney, or Los Angeles, the ability to service the newest vehicles is critical for business growth. JET-LS unlocks revenue from high-end JLR models that were previously off-limits.
This tool also completes your repair car key remote service. When a physical repair is not possible and the entire key fob must be replaced, JET-LS allows you to complete the job by programming the new, virgin key to the vehicle, providing a full start-to-finish solution for your customer.
Core Capabilities on DOIP/UDS Vehicles (2018+)
- All Keys Lost (AKL) Solution: The flagship feature. Successfully program new keys even when no working keys are present.
- Add-a-Key Functionality: Quickly and reliably add a spare key for a customer.
- Offline Security Authentication: Bypasses the need for an online JLR TOPIx connection by handling the seed/key security handshake locally.
- Targets Key Security Modules: Directly communicates with the locked-down RFA (Remote Function Actuator) and BCM (Body Control Module) to authorize new keys.
- Focused & Fast: Unlike broader engineering tools, JET-LS has one job: programming keys. Its interface is streamlined for speed and efficiency in the field.
Hardware Requirement: JLR DOIP VCI
To use JET-LS, you must have a compatible JLR DOIP VCI (Vehicle Communication Interface). This tool will not work with older J2534 or CAN-only devices. We recommend:
- Genuine Bosch JLR DOIP VCI
- Other high-quality, tested DOIP interfaces like the VXDIAG VCX SE for JLR.
This product is a software license only. The VCI is sold separately.
FOR PROFESSIONAL AUTOMOTIVE LOCKSMITHS ONLY
JET-LS is an advanced, powerful tool that directly manipulates a vehicle's core immobilizer system. It provides no safety nets. Incorrect use or a failed procedure can lead to a “bricked” BCM or RFA, resulting in extremely expensive repairs. This tool should only be handled by trained, experienced locksmiths who understand the risks and procedures involved.
LR-Retrofit is not responsible for any damage caused to a vehicle by the use or misuse of this software.
