Why does my car not start when I turn the key?
A low or bad battery can be easily tested with a standard ohm meter or at any auto repair shop or parts store (they usually do this free of charge). A loose battery cable connection is often the simplest of causes for a non-start. A bad starter solenoid means replacement is needed. Similarly, a bad starter is likely going to require replacement.
How does a key turn work on a starter motor?
The key turn completes a small circuit that tells the battery to release power to the starter solenoid. The solenoid ramps up the power given to it and that power causes the starter motor to turn very quickly.

If the engine does not crank, and the security / theft warning light stays on when it won’t start- and you let go of the key to the ON position, then this is most likely a problem in the Passlock system.
