Steps are as follows.
1. It is difficult to match a new key, especially a key with a chip, with the assistance of the vehicle detection computer. The vehicle detection computer can be purchased online by a third party decoder or borrowed from a familiar repair shop. After getting the vehicle detection computer, insert its plug into the vehicle OBD on-board diagnostic system jack. The OBD vehicle diagnostic system jack is generally located below the front of the main driving position, that is, below the steering wheel.
2. After the vehicle detection computer is inserted into the jack of the OBD on-board diagnostic system, adjust the vehicle to the vehicle power state with the original car key. When the vehicle detection computer is powered on, the plug indicator of the vehicle detection computer is red, and the blue indicator light should be flashed after the detection computer is successfully matched with the OBD on-board diagnostic system.
3, at this time you can accept the matching key into the keyhole, if the match is smooth, the key matching light will flash, should immediately operate the unlocking key on the original remote control, and then click the unlocking key of the new remote control, waiting for about ten seconds to complete the key pairing.
4. Finally, the chip of the original key can be removed and installed in the new key, and the whole key matching process is over. If you need to match the new key chip, open the detection computer key matching project, you can match the key chip.
The following Buick series models as an example to introduce the matching of car chip keys. Buick Vision: chip 4D60, frequency 434, password with frame number query, password hexadecimal 6 digits. Matching method: Big frame number conversion password, match with the country, follow the menu prompts, and then require a key switch once, so less than 2 keys.
