KEYS

KEY FOB
Your vehicle is equipped with a key fob which supports Passive Entry, Remote Keyless Entry (RKE), Keyless Enter ‘n Go™ (if equipped), Remote Start (if equipped), and remote power liftgate operation. The key fob allows you to lock or unlock the doors and liftgate, optional power liftgate, left power sliding door, and right power sliding door, from distances up to approximately 66 ft (20 m). When any button on the key fob is pushed, or when any signal is being transferred between the key fob and the vehicle, an LED light on the key fob will flash as an indicator. The key fob does not need to be pointed at the vehicle to activate the system. The key fob also contains an emergency key, which is stored in the rear of the key fob. The emergency key allows for entry into the vehicle should the battery in the vehicle or the key fob become depleted. The emergency key is also for locking/unlocking the glove compartment. You can keep the emergency key with you when valet parking.

NOTE:

1. The key fob’s wireless signal may be blocked if the key fob is located next to a mobile phone, laptop, or other electronic device. This may result in poor performance.
2. If your vehicle is equipped with a Wireless Charging Pad, the key fob may not be detected if it is placed within 6 inches (15 cm) of the pad.

Push and release the lock button on the key fob to lock all doors and the liftgate. When the doors are unlocked, the turn signals will flash and the illuminated entry system will be activated. When the doors are locked, the turn signals will flash and the horn will chirp. Settings in the Uconnect system can change to lights only, chirp only, or both.

Vehicles Equipped With Keyless Enter ‘n Go™ — Passive Entry
If one or more doors are open, or the liftgate is open, the doors can be locked. The doors will unlock again only if the key fob is inside the passenger compartment.
All doors can be programmed to unlock on the first push of the unlock button within Uconnect Settings.

Replacing The Battery In The Key Fob

The recommended replacement battery is one CR2032 battery.

1. Customers are recommended to use a battery obtained from Mopar®. Aftermarket coin battery dimensions may not meet the original OEM coin battery dimensions.
2. Batteries contain harmful chemicals. Dispose old batteries by placing them in correct containers according to the law or by taking them to a dealership, where they will be handled appropriately.
3. Perchlorate Material — special handling may apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate for further information.
4. Do not touch the battery terminals that are on the back housing or the printed circuit board.
5. Remove the emergency key by pushing the mechanical release button on the side of the key fob with your thumb and then pulling the key out with your other hand.
   
6. Insert a coin or a flat-blade screwdriver into the now exposed slot and carefully pry on both sides to disengage the snaps. Gently remove the back cover from the fob, being careful not to damage any of the snaps.
7. Remove the battery by sliding the battery rearward in its pocket until the battery lifts up. Remove the depleted battery from the battery pocket and dispose appropriately.
8. Fit a new CR2032 battery ensuring that the positive (+) side is facing upwards. Push the battery into the pocket until it is firmly seated in place and secured under both tabs.
9. Align the back cover into its original position and snap it back in place by pushing it against the fob until it is seated all around.

WARNING

1. The integrated key fob contains a coin cell battery. Do not ingest the battery; there is a chemical burn hazard. If the coin cell battery is swallowed, it can cause severe internal burns in just two hours and can lead to death.
2. If you think a battery may have been swallowed or placed inside any part of the body, seek immediate medical attention.
3. Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children.

Programming And Requesting Additional Key Fobs

Programming the key fob may be performed by an authorized dealer.

NOTE

1. Once a key fob is programmed to a vehicle, it cannot be repurposed and reprogrammed to another vehicle.
2. Only key fobs that are programmed to the vehicle elec-tronics can be used to start and operate the vehicle.

CAUTION

1. Always remove the key fobs from the vehicle and lock all doors when leaving the vehicle unattended.
2. Always remember to place the Keyless Enter ‘n Go™ Ignition in the OFF position.

SENTRY KEY

The Sentry Key Immobilizer system prevents unauthorized vehicle operation by disabling the engine. The system does not need to be armed or activated. Operation is automatic, regardless of whether the vehicle is locked or unlocked. The system uses a key fob, keyless push button ignition and a Radio Frequency (RF) receiver to prevent unauthorized vehicle operation. Therefore, only key fobs that are programmed to the vehicle can be used to start and operate the vehicle. The system cannot reprogram a key fob obtained from another vehicle.
After placing the ignition switch in the ON/RUN position, the Vehicle Security Light will turn on for three seconds for a bulb check. If the light remains on after the bulb check, it indicates that there is a problem with the electronics. In addition, if the light begins to flash after the bulb check, it indicates that someone attempted to start the engine with an invalid key fob. In the event that a valid key fob is used to start the engine but there is an issue with the vehicle electronics, the engine will start and shut off after two seconds. If the Vehicle Security Light turns on during normal vehicle operation (vehicle running for longer than 10 seconds), it indicates that there is a fault in the electronics. Should this occur, have the vehicle serviced as soon as possible by an authorized dealer.

CAUTION
The Sentry Key Immobilizer system is not compatible with some aftermarket Remote Start systems. Use of these systems may result in vehicle starting problems and loss of security protection.

All of the key fobs provided with your new vehicle have been programmed to the vehicle electronics.

IGNITION SWITCH

KEYLESS ENTER ‘N GO™ IGNITION
If applicable, refer to the “Hybrid Supplement” for additional information.
This feature allows the driver to operate the ignition switch with the push of a button as long as the key fob is in the passenger compartment.
The START/STOP ignition button has four operating positions; three of which are labeled and will illuminate when in position. The three positions are OFF, ACC, and ON/RUN. The fourth position is START. During START, RUN will illuminate.
