    I just replaced the hybrid in a 2007 model. I can't find the original key. I had bought an extra key but never programmed it. I installed the battery & hooked up all the terminals. My brother found instructions on programming the key. (Below) I got to step 8 and the Power is not coming on. I didn't even hear the hum that you normally hear when you step on the brake.
    I did notice that the screw grounding the negative terminal of the 12v is a little loose. The threads are wallered out a little.
    Any advice?


    1. OPEN the DRIVER'S side door and REMOVE key/remote out of ignition slot.

    2. INSERT and REMOVE key/remote from ignition slot TWICE.

    3. CLOSE and OPEN the DRIVER's side door TWICE.

    4. INSERT and REMOVE key/remote from ignition slot TWICE.

    5. CLOSE and OPEN the DRIVER's side door TWICE.

    6. INSERT and REMOVE key/remote from ignition slot TWICE.

    7. INSERT key/remote into ignition slot and CLOSE the DRIVER's side door.

    8. PUSH the POWER button (amber LED) to turn ignition ON and OFF TWICE.

    9. REMOVE key/remote from ignition slot. Vehicle will respond by cycling the door locks two times to indicate successful entry to programming mode.

    10. Within 40 seconds of door locks cycling Press and hold LOCK and UNLOCK buttons on first remote for 1.5 seconds then release. Immediately after releasing Press the LOCK button once. Vehicle will automatically Lock and Unlock the doors once to indicate successful programming or twice to indicate a failure in programming.
