The Yanhua Mini ACDP Module 24 is a specialized, solderless programming interface designed for programming duplicate smart keys on Jaguar and Land Rover (JLR) vehicles built from 2018 onward. By utilizing an innovative chip-replacement and clip-on adapter workflow, it safely writes data to blank SPC560B processors, bypassing modern OBD immobilizer security locks.
Solderless JLR 2018+ Key Programming: Mini ACDP Module 24 Technical Guide
Bypassing OBD Lockdowns: Navigating Modern JLR Post-2018 Security
From 2018 onward, Jaguar Land Rover updated their Remote Function Actuator (RFA) and Key Verification Module (KVM) architectures to combat growing vehicle theft vectors. These modern modules feature deeply locked microprocessors that actively reject traditional key programming diagnostic commands via the vehicle’s OBD-II port. While standard diagnostic interfaces can seamlessly write duplicate keys for the older JPLA-14C104-AF firmware version via OBD, all other late-model JLR vehicles require hardware-level modification to accept new smart keys.
The Yanhua Mini ACDP Module 24 offers an incredibly smart, reliable workaround to these complex factory restrictions. Rather than forcing workshops to purchase insanely expensive, brand-new RFA modules from franchised dealerships, Module 24 allows technicians to program secondary keys by physically replacing the locked microcontroller chip on the existing board with a blank SPC560B chip. Once configured, the vehicle’s security system is temporarily bypass-prepped, permitting standard key synchronization to occur quickly and reliably.
Safe SPC560B Blank Chip Preparation and Pin Detection Technology
Writing data to raw automotive chips traditionally carried massive hardware risks. Technicians previously had to weld microscopic jump wires directly onto the pins of the chip or use low-grade EEPROM sockets that suffered from unstable data signals. A single loose connection during a high-speed write cycle on an SPC560B processor can instantly corrupt the internal bootloader, rendering the chip completely useless and halting the programming job.
Module 24 mitigates these risks by incorporating a dedicated solder-free chip-clip adapter. This custom-molded clip fits perfectly over the replacement SPC560B blank processor on the bench, making physical connection with all critical communication leads. Before launching any flash sequence, the integrated ACDP software runs its proprietary Intelligent Pin Detection algorithm, verifying that every single physical contact pin exhibits perfect resistance and signal health. If any connection is imperfect, the software halts the process, protecting your data and physical hardware investment from damage.

💡 Mobile Eco Tuning Pro Tip:
Before beginning, check the vehicle’s software version via OBD. If the version is JPLA-14C104-AF, you can duplicate the key directly via OBD using Module 24 without any chip replacement. For all other versions, you must replace the RFA CPU. Make sure to desolder the original locked SPC560B processor cleanly from the board. When mounting the new blank SPC560B chip into the ACDP clip adapter, double-check that Pin 1 matches the designated notch on the plastic board. Run the Pin Detection algorithm in the software to confirm all green contacts before executing the write command. When programming is complete, solder the newly prepared blank chip back onto the RFA board, reinstall it in the vehicle, and perform the standard key learning process over OBD. To ensure complete compatibility with factory immobilizer systems, always use a high-quality aftermarket smart key that supports ID changes (such as Lonsdor JLR keys).
