Decode and cut key blade with Xhorse dolphin XP005L.
Used a 12+8 FCA cable from xtool and autel im508s.
It worked just fine had to remove the cluster to access the connectors.

Autel MaxiIM IM508S and IM608 II series now support programming Toyota 8A_BA and 4A_BA proximity all keys lost. Take an example of a 2024 Toyota Frontlander HV.
Tools requires:
Main steps:
Procedure:
Step 1: Back up IMMO Data
Perform the “Back up IMMO Data” function to obtain the vehicle’s eeprom bin file, which is used to generate an analog key and facilitate the PIN-free process.
Menu path: Toyota- Manual selection- Other- Frontlander HV- Smart Key-4A- Control Unit- Keyless System (CAN).
Select Back up IMMO Data function.
This function supports models with 4A Smart key as of 2022.

Enable network connection.
Turn the ignition off and turn the hazard warning lamps on and off once.
Follow the operation guide to connect jumper wires to the smart box.
Connect the OBD-II diagnostic connector of the vehicle, the smart main control module A connector and the main test cable using flying wires as shown in the figure (Note: Location of the smart main control module may vary with vehicle model):
Connect the main test cable to the OBD-II diagnostic connector of the vehicle using a flying wire and connect the power supply (+12 V) and ground (GND).
Connect the main test cable to the smart main control module A connector using a flying wire and connect CAN-H and CAN-L. As shown in the figure, connect CAN-H to the smart main control module A connector pin 1 cable and CAN-L to the smart main control module A connector pin 2 cable using spliced wires.
Connect the jumper cable with smart box.
Step 2: Generate Analog Key
Perform the “Generate analog key” function by loading the backed-up EEPROM bin file, generate the analog key and verify that its emergency ignition function works correctly.
Connect APB112 emulator.

Put the APB112 emulator on the Start button.

Generate the analog key successfully.
Step 3: Add smart key
Disconnect the jumper wire and connect the diagnostic connector directly to the vehicle’s OBDII port.
Perform the “Add smart key” function by loading the backed-up EEPROM bin file to enable PIN-free operation.
Follow Autel prompts to verify PIN and learn key.
Test the new key.
Autel MaxiIM IM508 & IM608 also support reading original NCF29xx NXP smart key data to copy a spare key.
Currently supported NXP types:
NCF2951, NCF2953, NCF295E, , NCF2971, NCF29A1, NCF29A2, NCF29A3, NCF29A4, NCF29A7, NCF29AE.
Tool required
Autel MaxiIM IM508/IM608
Autel XP400 Pro
Autel APB131 cable (can also copy key without apb131)
Original key
New key to be cloned.
Procedure:
Go to the Programmer function.
Select Chip (EEPROM/MCU/ECU)- Chip Reading/Writing- MCU-NXP-NCP29XX.
Select the correct NXP chip type.
For example: NCF29A7
Check the key connection diagram

Connect the apb131 cable to key circuit board according to the diagram.

Read and save original key data.
Possible to program newer 2023 Nissan Serena smart key with Autel IM508/IM608?
Any risk if we try it with Nissan 40pin BCM cable?
Here is the clue.
Sometimes it works; sometimes it does not. If Autel fails, try Lonsdor. If all fail, try the key cloning function.
User’s working experience:
“Did one with Autel IM608 last week. After I plugged 40 pin cable, I lost communication. So I read basic data (key positions and ID’s) throught basic OBD connection and made key clone with Autel (but wrote lost ID in new key). Both keys worked perfect; no remote sync issue will appear cause there are 2 different keys ID’s.
Autel NXP copy is the the same as NXP killer.
NXP killer makes only direct clone of key, you cannot change ID. Its simple copy-paste function. Autel hacked this type of NXP chip too with changing ID’s feature. So with NXP killer you could have sync issues, with autel you won’t (if you choose lost keys ID to new one).
Autel MaxiIM IM508/IM608 series now supports Nissan NCF29Ax NXP smart key cloning function.
Supported models:
2019- Ariya, Pathfinder, X-Trail, Qashqai, Sylphy, E-POWER, HB18, KICKS, MICRA, Note e-POWER, NP300 FRONTIER, NAVARA, NP300 NAVARA, PRIMASTAR, R53, ROGUE, Serena e-POWER, Sylphy e-POWER, SYLPHY Zero Emission, TOWNSTAR.
2121- RH850 series Infiniti QX60, QX60 hybrid
Supports copying AUTEL ikey universal and original keys. AUYEL smart keys need to be generated in advance.
Remove the original car key.
Connect the XP400 Pro programmer, key board, and APB131 adapter.
If you cannot find the wiring diagram for the exact key board type, refer to the key chip wiring diagram based on the chip type to perform the reading.
Read and save key data.
Then write a new Ikey or original key.
