With a traditional ignition, insert the key, turn to ON/RUN, depress the brake, then turn to START and release. The engine should start and the key will return to RUN; keep the transmission in Park and the parking brake engaged.
Chevrolet Cruze ignition setups vary by model year and trim. This article explains how to start using a standard key, notes how things differ for keyless start systems, and offers troubleshooting steps if the car does not start.
Ignition options in the Chevrolet Cruze
Chevrolet Cruze models from around 2009 through 2019 used two main ignition setups: a traditional keyed ignition (LOCK/ACC/ON/START) and a keyless system that uses a fob. The instructions below focus on the traditional key, with brief notes for models that use a Start button.
Traditional keyed ignition (older models)
Follow these steps to start your Cruze if you have a conventional key slot in the steering column.
- Insert the key fully into the ignition cylinder.
- Turn the key from LOCK/ACC to ON or RUN to power the electronics.
- With your foot on the brake (automatic) or clutch (manual), turn the key to the START position and hold briefly until the engine begins to run.
- Release the key to the ON/RUN position once the engine starts.
- Ensure the transmission is in Park (automatic) or Neutral (manual) and engage the parking brake.
- Observe that the dash indicators come up normally and the engine idles smoothly before driving away.
If the engine fails to start after a few seconds, wait a moment and try again. If repeated attempts fail, there may be a battery, starter, or immobilizer issue that needs service.
Keyless Start (for comparison)
Some Cruze trims use a key fob and a push-button start. If your model has this system, keep the fob inside the vehicle, press the brake pedal, and press the Start/Stop button to start the engine. If the fob battery is dead, you may need to insert a physical key into the slot if available, or use a dedicated emergency start procedure outlined in the manual.
Troubleshooting if the Cruze won’t start
If the Cruze doesn’t start after following the steps above, try the following checks to pinpoint common issues.
- Check the battery: test for adequate voltage (a healthy 12.6 volts or higher when the engine is off). Look for dim lights or a slow cranking sound, which can indicate a weak battery.
- Inspect the battery terminals: clean any corrosion and ensure the connections are tight.
- Immobilizer/security indicator: if the security light (padlock) stays on or flashes, there may be an immobilizer issue or a faulty key transponder. Consult the manual or a dealer for reprogramming or replacement.
- Starter and fuses: check fuses in the starting circuit; a blown fuse can prevent cranking.
- Fuel supply: ensure there is fuel in the tank and the fuel pump is delivering fuel (you may hear a soft whir from the rear when turning the key to ON).
- Cranks but won’t start: possible fuel or ignition problem; consider professional diagnostic.
In case of persistent issues, contact roadside assistance or a Chevrolet dealer. For safety, do not attempt to bypass security systems or force the ignition cylinder; repeated attempts can cause further damage.
Summary
Starting a Chevrolet Cruze with a traditional key is a straightforward sequence: insert the key, turn to ON, press the brake, turn to START, and release. For models with keyless start, use the Start button with the fob present. If the engine fails to start, check the battery, ignition, and immobilizer, and seek professional help if needed. Regular maintenance and timely battery replacement help prevent starting problems.
