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 starting the engine). The security light on the dashboard will illuminate and stay on for ten minutes. When the security light goes out, you have one minute to proceed to the next step.
2. Turn the ignition cylinder to OFF and then back to the ON position. The security light on the dash will illuminate and stay on for another ten minutes. Again, when the security light goes out, you have one minute to proceed.
3. Repeat step 2: turn the ignition cylinder to OFF and then back to the ON position. The security light on the dash will illuminate and stay on for another ten minutes.
4. After the security light has turned 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 key and start the vehicle to test it.

Can I program a duplicate key for this vehicle?

1. Insert an existing programmed working key into the ignition cylinder.
2. Turn the ignition to the ON position and then back to OFF.
3. Remove the existing key and, within ten seconds, insert the new key and turn it to the ON position.
4. The security light will illuminate for two seconds to indicate successful programming of the additional key. Remove the key from the ignition.
5. Insert the key and start the vehicle to test it. Visit keylesscanada.com for key fob programming instructions.
