Step-by-Step Programming Instructions:

You cannot program a new key yourself if you have no working keys. Here are your options:

1. Preferred Option: Call a mobile Automotive Locksmith to come to your vehicle and create a new key. The Locksmith will need to connect a special computer to your vehicle to program the new key.
2. Alternatively, you can tow your vehicle to a Dealership, and they will create a new key for you. The Dealership will also use a special computer to program the new key.

If you have one working key and want to program a second one, you cannot do it yourself. Here are your options:

1. Preferred Option: Contact an Automotive Locksmith who can connect a special computer to your vehicle to program the second key.
2. Another option is to visit a Dealership, where they’ll use their specialized computer to program the second key.

However, if you have two working keys and want to program a third one, you can do it yourself. Here’s how:

1. After having the new key cut by a Locksmith, insert one of the existing working keys into the ignition cylinder.
2. Turn the ignition cylinder to ON (RUN) and then back to OFF.
3. Remove the existing working key, and within five seconds, insert the second working key and turn it to ON (RUN), then back to OFF.
4. Remove the second working key and insert the new key within ten seconds. Turn it to ON (RUN) and leave it for one second before turning it back to OFF.
5. The security light will illuminate for three seconds, indicating that the new key has been successfully programmed.

Remember, once the key is successfully programmed, do not remove it from the ignition. Leave it in the cylinder for 10 minutes to complete the programming procedure. If you attempt to start the vehicle or remove the key before this time, you’ll need to restart the entire procedure.
