Can I program a new key myself if I don’t have any working keys?
Yes, once you have the new key cut by a locksmith, follow these instructions:

1. Insert the new key into the ignition cylinder and turn it to the ON position (as far as it can go without cranking the engine). The security light on the dashboard will illuminate and remain on for ten minutes. When the security light goes out, you have one minute to start the next step.
2. Turn the ignition cylinder to OFF and then back to the ON position. The security light on the dashboard will illuminate and remain on for another ten minutes. When the security light goes out, you have one minute to start the next step.
3. Turn the ignition cylinder to OFF and then back to the ON position. The security light on the dashboard will illuminate and remain on for ten more minutes.
4. After the security light has gone off for the third time, turn the key off and remove it from the ignition. The key is now programmed, and all other keys have been erased.
5. Insert the programmed key and start the vehicle to test the key.
