Adding a new smart key card to a Renault Captur 2020 using the OBDSTAR X300 Classic G3 tool is a detailed process that requires careful execution. Below is a step-by-step guide based on a real-world procedure, including important tips during the process.
Tools required:
Xhorse blank XS series smart key
Original smart key
Step 1: Accessing the Gateway Module
The gateway module (gate) must be accessed to bypass the vehicle’s security system. According to the manual, it is located under the dashboard, but in this case, it was found behind the multimedia unit.
Steps to Access the Gateway:
1. Remove the glove compartment and surrounding plastic panels.
2. Detach decorative trims, which may be secured by bolts hidden beneath them.
3. Loosen (or remove) the multimedia unit to reach the gateway, located at the top behind it.
Step 2: Connecting the OBDSTAR G3 Tool
Once the gateway is accessible:
1. Use a 16+32 adapter to connect the gateway’s 32-pin connector.
2. Ensure the CAN lines are fully accessible for direct communication.
3. Connect an external power source to prevent voltage drops during programming. External power is critical to avoid interruptions.
Step 3: Programming the Key
Select Renault in the OBDSTAR menu.
The tool automatically detects the model (Renault Captur) and retrieves the VIN.
Select the proximity key- Add key (free pincode).
OBDSTAR G3 asks to connect Nissan/Renault 16+32 adapter to bypass gateway. Check connection instructions.

Common Issues and Solutions
Failed Key Programming:
If the original key fails to program, try adding a new key first, then reprogram the original.
Ensure the transponder is correctly placed in the reader.
Incorrect Key Count Display:
The immobilizer may show incorrect key counts. Verify functionality by testing each key.
Alternative Method (HFM Direct Access):
If the gateway is hard to reach, the HFM module (located near the dashboard) can sometimes be used to extract the PIN directly. Direct reading pin from HFM dump is better, in case of complete loss and failure without isk data you won’t be able to prepare the card. The task will be with two unknowns, no card and empty hfm. The dealer does not send cards prepared for the car. You can take isk data from the server, but the procedure will require a prepared card.
