The Sentry Key Immobilizer System (SKIS) prevents unauthorized operation of the vehicle by disabling the engine. The system will shut the engine down after 2 seconds of running if an invalid key is used to start the vehicle. This system utilizes ignition keys which have an electronic chip (transponder) embedded into them. Only keys that have been programmed to the vehicle can be used to start and operate the vehicle for longer than the 2 second validation time period. All of the keys provided with your new vehicle have been programmed to the vehicle electronics.

The Sentry Key Immobilizer System does not need to be armed or activated. Operation of the system is automatic regardless of whether or not the vehicle is locked or unlocked. During normal operation, the SKIS indicator light will come on for 3 seconds immediately after the ignition switch is turned on for a bulb check. Afterwards, if the bulb remains on, this indicates a malfunction in the electronics. If the bulb begins to flash immediately after the ignition switch is turned on, this indicates that an invalid key is being used to start the vehicle. Both of these conditions will result in the engine being shut down after 2 seconds of running. Keep in mind that a key which has not been programmed is also considered an invalid key even if it is cut to fit the ignition for that vehicle.

If the SKIS indicator light comes on during normal vehicle operation (it has been running for longer than 10 seconds) a fault has been detected in the electronics and the vehicle should be serviced as soon as possible.

NOTE: The Sentry Key Immobilizer System is not compatible with remote starting systems. Use of these systems may result in vehicle starting problems and loss of security protection. Mobil SpeedpassTM, additional Sentry Keys, or any other transponder equipped components on the same keychain will not cause a key-related (Transponder) fault unless the additional part is physically held against the ignition key being used when starting the vehicle. Also, cell phones, pagers, or other RF electronics will not cause interference with this system.

Starting with 2005 models, the Remote Keyless Entry (RKE) transmitter is built-in to the key fob, as shown in the photo above. In addition, a fourth button has been added to allow automatic opening of the rear flipper glass. Once the button is pressed, the glass is not only unlocked, but automatically rises.

For additional security, two pre-programmed keys are needed in order to register additional keys into the system. In the event of the loss of all keys, special programming equipment is needed to register new keys into the system.

It is highly recommended that you get a spare third key made and programmed for your Jeep. It's a good idea to do this while you still have your two original keys. If you were to ever lose one of those keys, it's a lot more costlier to have a replacement made as you must go to the dealer or a specialty locksmith to have the programming done. With your own pair of original keys, you can easily program a new key yourself.

A four digit PIN number is needed to service the Sentry Key Immobilizer System. This number can be obtained from your authorized dealer. However, this number can also be found on your customer invoice that you were given upon receipt of your vehicle.

NOTE: Once a Sentry Key has been programmed as a valid key to a given vehicle, it cannot be programmed as a valid key for use on any other vehicle.

At the time of purchase, the original owner is provided with a four digit PIN number. This number is required for dealer replacement of keys. Duplication of keys may be performed at an authorized dealer or by using the Customer Key Programming procedure. This procedure consists of programming a blank key to the vehicle electronics. A blank key is one which has never been programmed.

NOTE: When having the Sentry Key System serviced, bring all keys to the dealer.

CUSTOMER KEY PROGRAMMING:

1. Cut the additional Sentry key transponder blanks to match the ignition switch lock cylinder key code.

2. Insert the first valid key into the ignition switch and turn the ignition switch ON for at least 3 seconds but no longer than 15 seconds. Turn the ignition switch OFF and remove the first key.

3. Insert the second valid key and turn the ignition switch ON within 15 seconds. After 10 seconds, a chime will sound and the SKIS indicator light will begin to flash. Turn the ignition switch OFF and remove the Sentry key.

4. Insert a blank Sentry Key into the ignition switch and turn the ignition switch ON within 60 seconds. After 10 seconds, a single chime will sound. The SKIS indicator light will stop flashing, turn on for 3 seconds, then turn off.

The new Sentry Key has been programmed. Repeat this procedure to program up to a total of 8 keys.

REMOTE KEYLESS ENTRY FUNCTIONS:

This system allows you to lock or unlock the doors, liftgate, or activate the panic alarm from distances up to about 23 feet (7 meters) using a hand held radio transmitter. The transmitter need not be pointed at the vehicle to activate the system.

NOTE: If the key is in the ignition switch, then all buttons on that transmitter will be disabled. The buttons on the remaining transmitters will work. If the vehicle is shifted out of P (Park), all the transmitter buttons are disabled for all keys.

To Unlock the Doors

Press and release the "Unlock" button on the transmitter once to unlock the driver's door, or twice to unlock all doors. The turn signal lights will flash twice to acknowledge the unlock signal. The illuminated entry system also turns on.

NOTE: If desired, the system can be programmed to unlock all doors on the first press of the "Unlock" button. Refer to "Remote Unlock Driver's Door 1st" in the Personal Settings section of the "Electronic Vehicle Information Center (EVIC)", or simply follow these steps:

If your Remote Keyless Entry transmitter fails to operate from a normal distance, check for these two conditions.

1. A weak battery in the transmitter. The expected life of the battery is a minimum of three years.

2. Closeness to a radio transmitter such as a radio station tower, airport transmitter, and some mobile or CB radios.

Transmitter Battery Service

The recommended replacement battery is one CR2032 battery

NOTE: Do not touch the battery terminals that are on the back housing or the printed circuit board.

1. With the transmitter buttons facing down, use a small screwdriver or similar flat object to pry the two halves of the transmitter apart. Make sure not to damage the rubber gasket during removal.

Separating Transmitter Halves

2. Remove and replace the battery. Avoid touching the new battery with your fingers. Skin oils may cause battery deterioration. If you touch a battery, clean it with rubbing alcohol.

3. To reassemble the transmitter case, snap the two halves together. Make sure there is an even "gap" between the two halves. Test transmitter operation.

SECURITY ALARM SYSTEM - IF EQUIPPED

This system monitors the vehicle doors, liftgate, liftgate flipper glass, and ignition for unauthorized operation. When the alarm is activated, the system provides both audible and visual signals. The horn will sound repeatedly for three minutes and the headlights and taillights will flash for an additional 15 minutes.

To Set the Alarm

The alarm will set when you use the remote keyless entry transmitter to lock the doors and liftgate or when you use the power door lock switch while the door is open. After all the doors are locked and closed, a red light (located in the instrument cluster) will flash rapidly for about 16 seconds to signal that the system is arming. During this 16 second pre-arm period, opening any door or the liftgate will cancel the arming. If the system successfully arms, the red light will flash at a slower rate to indicate the alarm is set. A manual lock of the doors, either with the door lock plunger located on the inside of the doors or with the driver's door key lock cylinder, will not set the alarm.

To Disarm the System

To disarm the system, use the remote keyless entry transmitter or the key to unlock the driver's door. If something has triggered the system in your absence, the horn will sound three times when you unlock the doors. Check the vehicle for tampering.

The Security Alarm System is designed to protect your vehicle; however, you can create conditions where the system will arm unexpectedly. If you remain in the vehicle and lock the doors with the transmitter, once the system is armed (after 16 seconds), when you pull the door handle to exit the alarm will sound. If this occurs, press the "Unlock" button on the remote keyless entry transmitter to disarm the system. The Security Alarm System will not disarm with a manual unlock, either through the lock plunger located on the inside of the door, or through a key in the driver's door key cylinder.

OPTIONAL DRIVER MEMORY SYSTEM

Once programmed, the memory buttons 1 and 2 on the driver's door panel can be used to recall the driver's seat, driver's outside mirror, adjustable brake and accelerator pedals, and radio station preset settings. Your Remote Keyless Entry transmitters can also be programmed to recall the same positions when the "Unlock" button is pressed.

Your vehicle may have been delivered with two Remote Keyless Entry transmitters. One or both transmitters can be linked to either memory position. The memory system can accommodate up to four transmitters, each one linked to either of the two memory positions.

Setting Memory Positions and Linking Remote Keyless Entry Transmitter to Memory
