select the car's make, model, year, and VIN number
On the KM100's touchscreen, you'll need to select the car's make, model, year, and VIN number (if the system doesn't automatically detect it).If you don't have the VIN number on hand, you can use the vehicle's key code or immobilizer code if available.
The KM100 has four methods for quick car identification
Depending on your needs, the KM100 offers several options:
Key Programming: Select this option if you want to program a brand-new transponder key or smart key. The KM100 will read the vehicle's security system and generate the key's programming data.
Key Cloning: If you want to duplicate an existing working key, select “Key Cloning.”The KM100 will copy the data from the original key and generate a duplicate key with identical programming.
Remote Key Fob Programming: If you've lost or need a replacement key fob, choose this option to program a new remotekey fob.
For Transponder Keys: After selecting "Key Programming," the KM100 will prompt you to insert the new key into the ignition (if applicable) or to place the key near the vehicle's ignition sensor (for proximity keys).The KM100 will then send the necessary data to the vehicle's ECU and sync the new key to the car's immobilizer and security system.
For Remote Key Fobs: If you're programming a remote key fob, the KM100 will walk you through the process of syncing the key fob's signal with the vehicle's remote entry system.
Use KM100 for key programming to generate a new key
After the programming process is complete, the KM100 will prompt you to test the new key. Insert the key into the ignition or use the keyless entry system to check if the key works as expected. If programming a remote key fob, test whether the lock/unlock buttons function properly.
Once the key is successfully programmed and tested, the KM100 will display a confirmation message.You can then remove the KM100 from the OBD-II port and safely store the new key.
