IF YOU CONFIRM All "hands free" functions of the Intelligent Key (I-Key) do not work. For example, the doors will not lock or unlock when pressing either front door request switch. NOTE: - The issue of all I-Key "hands free" functions not working may occur intermittently or all the time. - The message "No Key Detected" or similar may show on the Vehicle Information Display (located in the combination meter). - All I-Key remote button functions (door lock/unlock, etc.) WILL work normally when all I-Key "hands free" functions are NOT working. ACTION 1. Inspect the I-Key?s battery on its negative contact side. 2. If excessive scratching is found, replace the battery. 3. Verify all I-Key functions (both "hands free" and remote) work properly after battery replacement. NOTE: Do NOT replace the BCM, I-Key, or other parts for the issue described under IF YOU CONFIRM, if it should occur. See this bulletin for further detail.
