WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
Before troubleshooting the immobilizer system, check the following general items and solve any if applicable:
- If the battery is low; charge the battery fully, then troubleshoot the immobilizer system.
- If the ignition key is not a genuine Acura part; use the Acura-approved key blank, register the key, then troubleshoot the immobilizer system.
- Check the key ring, or keys, or if a key case is used; remove the key from it, and troubleshoot the immobilizer system with a key only.
- If an aftermarket electrical part is attached; remove it, then troubleshoot the immobilizer system.
