Chevy Monte CarloMy alarm system wont let my car start


First try a different ignition key if you have one. The ignition key has a chip that is required to start the engine. If this doesn’t work then try this.

  • Disconnect the battery
  • Turn ignition key to “ON”
  • Connect battery
  • Move ignition key from “ON” to “START”

This should reset the alarm and allow it to run. If it still does not you may need to disassemble the steering column an repair the wiring at the key lock cylinder for the connections that go to the chip in the key.
