Bobby pin ????

Yes, a Bobbie Pin, the article said to use a Paper Clip that I couldn't find, so that's what I used because it is also metal which was perfect for connections.

3. Hold down the power UNLOCK button on the driver?s door panel-continue to hold
down until instructed to release in step 9.

4. Perform steps 5 through 8 in fairly rapid succession.

5. Turn the ignition switch to the ON position (as far as you can go without starting the
engine).

6. Turn the ignition switch to the OFF position.

7. Turn the ignition switch to the ON position.

8. Turn the ignition switch to the OFF position.

9. Release the power unlock button on the door panel. The vehicle will lock and unlock
the doors automatically.

10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until
the door locks and unlocks.
