Keys and Remote Controls
GENERAL INFORMATION ON RADIO FREQUENCIES
This device complies with Part 15 of the FCC Rules and with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
WARNING:
Changes or modifications not expressively approved by the party responsible for compliance could void the user’s authority to operate the equipment. The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met. The typical operating range for your transmitter is approximately 33 ft (10 m). Vehicles with the remote start feature will have a greater range. One of the following could cause a decrease in operating range:
- Weather conditions.
- Nearby radio towers.
- Structures around the vehicle.
- Other vehicles parked next to your vehicle.
The radio frequency used by your remote control can also be used by other radio transmitters, for example amateur radios, medical equipment, wireless headphones, wireless remote controls, cell phones, battery chargers and alarm systems. If the frequencies are jammed, you will not be able to use your remote control. You can lock and unlock the doors with the key.
Note: Make sure to lock your vehicle before leaving it unattended.
Note: If you are in range, the remote control will operate if you press any button unintentionally.
Note: The remote control contains sensitive electrical components. Exposure to moisture or impact may cause permanent damage.
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 are met:
- You activate the front exterior door handle switch.
- You press the luggage compartment button.
- You press a button on the transmitter.
If excessive radio frequency interference is present in the area or if the transmitter battery is low, you may need 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.
REMOTE CONTROL
Intelligent Access Key Note: You may not be able to shift out of park (P) unless the remote control is inside your vehicle.
The remote control operates the power locks and the remote start system. The key must be in your vehicle to use the push button start.
Removable Key Blade The remote control also contains a removable key blade that you can use to unlock your vehicle.
Note: Your vehicle keys came with a security label that provides important key cut information. Keep the label in a safe place for future reference.Using the Key Blade The key cylinder is under a cap on the driver door handle. To remove the cap
- Insert the key blade into the slot on the bottom of the handle and apply upward pressure.
- While maintaining upward pressure, move the cap rearward to release it. Gently remove the key while doing so.
To install the cap:
- Place the cap just forward of the key cylinder.
- Applying pressure to the cap, move it forward until it is in place. You may hear a snap as it engages.
Make sure you have properly installed the cap by trying to move it rearward.
Replacing the Battery
WARNING: Keep batteries away from children to prevent ingestion. Failure to follow this instruction could result in personal injury or death. If ingested, immediately seek medical attention.
WARNING: If the battery compartment does not securely close, stop using the remote control and replace it as soon as possible. In the meantime, keep the remote control away from children. Failure to follow this instruction could result in personal injury or death. A message appears in the information display when the remote control battery is low. The remote control uses one coin-type three-volt lithium battery CR2450 or equivalent.
- Push the release button and pull the key blade out.
- Twist a thin coin under the tab hidden behind the key blade head to remove the battery cover.
- Insert a suitable tool, for example a screwdriver, in the position shown and carefully remove the battery. Note: Refer to local regulations when disposing of remote control batteries. Note: Do not wipe off any grease on the battery terminals or on the back surface of the circuit board. Note: Replacing the battery does not erase the programmed key from your vehicle. The remote control should operate normally.
- Install a new battery with the + facing upward.
- Reinstall the battery cover and the key blade.

INTERIOR LUGGAGE COMPARTMENT RELEASE
WARNING:
Keep vehicle doors and luggage compartment locked and keep keys and remote transmitters out of a child’s reach. Unsupervised children could lock themselves in the trunk and risk injury. Children should be taught not to play in vehicles.
WARNING: Do not leave children or animals unattended in the vehicle. On hot days, the temperature in the trunk or vehicle interior can rise very quickly. Exposure of people or animals to these high temperatures for even a short time can cause death or serious heat-related injuries, including brain damage. Small children are particularly at risk. Your vehicle is equipped with a release handle that provides a means of escape for children and adults if they become locked inside the luggage compartment. Adults should familiarize themselves with the operation and location of the release handle.
The handle is located inside the luggage compartment either on the luggage compartment door (lid) or near the tail lamps. It is composed of a material that will glow for hours in darkness following brief exposure to ambient light. Pull the handle and push up on the luggage compartment door (lid) to open from within the luggage compartment.
