key fobs not working
key fobs not working 2000 z28, car came with 2 remotes but neither worked, So I replaced both batterys and tested them at O'reilys and that both work, SO i tried reprograming them, used these instructions,
1. Turn the ignition key to RUN, then to OFF. This will disarm the content theft-deterrent/alarm system (if equipped).
2. Remove the RADIO fuse. This fuse is located in the main fuse block which is located on the left side of your instrument panel.
3. Turn the ignition key from OFF to RUN three times quickly (within five seconds). The vehicle will respond by locking the doors, unlocking the driver’s door and releasing the hatch. Your transmitter is now ready to match the vehicle. Leave the ignition in RUN.
4. Press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The vehicle will respond as in Step 3.
5. Repeat Step 4 for the remaining transmitters.
6. When you have finished matching all of your transmitters, turn the ignition off and replace the RADIO fuse.
7. Check that all transmitters work by pressing the buttons.
the responds to step 3 but not step 4 with either remote. I had another fob I tried and still nothing, what else could it be?
