54 Keys and Remote Control Intelligent Access The system uses a radio frequency signal to communicate with your vehicle and authorize your vehicle to unlock when one of the following conditions is met: • You touch any button on the keypad. • You press a button on the transmitter. If excessive radio frequency interference is present in the area or if the transmitter battery is low, it may be necessary to mechanically unlock your door. You can use the mechanical key blade in your intelligent access key to open the driver door in this situation. Refer to Remote Control in this chapter for more information on the location and use of the mechanical key blade. REMOTE CONTROL Intelligent Access Key Your intelligent access keys operate the power locks and the remote start system. The key must be in your vehicle to activate the push-button start system. The intelligent access key also contains a removable mechanical key blade that you can use to unlock the driver door. Slide the release on the back of the transmitter to release the key blade, and then pull the blade out. Note: Your vehicle's back-up keys came with a security tag that provides important key cut information. Keep the tag in a safe place for future reference.
