How to Match A Car Chip Key by Key Programmer?

The matching process of car chip keys requires the combination of professional equipment and operating steps, and the specific methods vary depending on the vehicle model and year. The following is a common matching method:

1. Prepare tools and equipment:

You need an OBDII scanner (for reading the vehicle identification number VIN), a key programmer (for writing key data), a key battery (for testing keys), and some screwdrivers.

2. Obtain key data:

Find the OBDII interface of the car (usually located under the steering wheel), use the OBDII scanner to read the vehicle's identification number VIN (save this information for later use).

3. Clear the fault code:

If the key cannot unlock the car door, it may be necessary to first clear the fault code in the anti-theft system. Use an OBDII scanner to perform this operation.

4. Programming key:

Insert the key into the key programmer and input the correct data on the programmer based on the VIN and other relevant information displayed by the OBDII scanner. Then follow the instructions of the programmer to operate.

5. Test key:

Test whether the new key can lock and unlock the car normally. If successful, the key has been correctly matched. If unsuccessful, it may be necessary to re-enter data or replace the key battery.

Please note that different vehicle models may require different methods and tools. If you are unsure how to operate, it is recommended to seek professional help.
