for that you can just program a new key by using the original. the only thing that requires one original part is the chipped key that is in the 2008 h3 (as well as many other products from GM). H3’s do not have a way to do it with out using a GM scan tool.(it’s true that some other GM products do not require the scan tool.) I know, i’m a gm tech. Tech 2 is needed to place the system into the programming mode.Climb out of the vehicle and try locking and unlocking the doors with your remote key. This indicates the programming has been successful.Ħ Remove the key from the ignition. 5 Insert the key into the ignition and turn it to the “On” position. Release the buttons when the locks click again.

Remove key.Ĥ Push both the “Lock” and “Unlock” buttons on the key-less remote and hold them for roughly 15 seconds. At this point, release the “Unlock” button on the driver’s door. As you complete this sequence, the doors will lock, and the horn will sound, indicating that you’ve entered the programming mode. Then return the ignition key to the “Off” position. Continue holding down the “Unlock” button.ģ Turn the ignition key back to the “Off” position while continuing to hold the “Unlock” button then return the key to the “On” position again. Insert the key into the ignition but do not turn on the vehicle.Ģ Hold down the “Unlock” button on the driver’s door while turning the key to the right to the “Accessories” position.

NO TOOL instructions: (have a try before program with scan tool TECH2)ġ Climb into the vehicle and close the door. I have done this numerous times on Ford products but can not find the instructions on line for my H3. Last month, I lost a set of keys, ordered a new RKE & blank key, and got the key cut & it works perfect.
