Symptom Troubleshooting: Engine does not start with the built-in key

NOTE: Before troubleshooting, check the following general items:

- If there is a keyless access system symptom, troubleshoot the keyless access system first.

- The battery voltage is low; charge the battery fully, then troubleshoot the immobilizer system.

- The ignition key is not a genuine Acura part; use the Acura approved key blank, register the key, then troubleshoot the immobilizer system.
