2. Insert an already programmed master key into the ignition.

3. Turn the key in the ignition ON and OFF FIVE (5) times.

4. Open and close the drivers door SIX (6) times.

5. Remove the key from the ignition.

6. Insert the new key you want to program into the ignition.

7. Wait up to 2 minutes. The security light will be blinking for up to 2 minutes. When it stops blinking your key is programmed. To end programming step on the brake one time. NOTE: You have 35 seconds to complete steps 1-5 and 10 seconds to complete step 6. If you do not do this procedure fast enough the car will not go into programming mode and your key will not program.If the security light does not go out after 2 minutes start the procedure over again. ----

5. Close and open the drivers door two times.

6. Put key into the ignition. Close the drivers door.

7. Turn ignition ON then OFF ONE TIME- this will put the car in ADD mode for your remote. (Turning the ignition ON then OFF TWO TIMES will ADD the remote but will erase all existing remotes.)

8. Remove the key from the ignition. The door locks will cycle one time (or two if you are erasing) . On the REMOTE press and hold the LOCK and the UNLOCK button for 2 seconds. On the REMOTE press the LOCK button for one second. AT THIS POINT, the locks should cycle by themselves ONE time. This means the procedure was accepted. IF the locks cycle twice it has failed. IF this happens you must start over. Hold the remotes higher up for better reception 9. Open and close the drivers door. Put key in ignition and pull out. This will end
