For 1990-2009 cars

The remote keyless entry (RKE) is a feature which allows for the operation of the door locks, interior lighting, and the decklid/liftgate release from outside the vehicle.

The RKE system consists of a body control module (BCM) and 2 transmitters. The BCM can be programmed with up to 4 transmitters. The transmitter sends a signal to the BCM when lock, unlock, or the vehicle symbol button is depressed. The BCM interprets the signal, decodes it and then executes it by activating the required circuitry to provide the requested function.

The Saturn Security System is a feature that is operated from the RKE transmitter. The Saturn Security System provides content theft protection by sounding the horn and flashing the DRL lamps if a door is opened or the ignition lock cylinder is turned. This system does not disable the vehicle.

### RKE Functions

### Lock

All the doors will lock automatically when LOCK is pressed on the transmitter. The dome lamp will illuminate for two seconds as soon as all the doors are closed. If the security system function is enabled, the DRL lamp will flash once.

The Saturn Security System is automatically enabled when the LOCK button is pressed on the transmitter. The horn will chirp when the LOCK button is pressed a second time, depending on the system mode chosen.

If the lock button is pressed and any door or trunk is open the BCM will chime 3 times, and the security telltale will stay on solid. When the doors or decklid/liftgate is closed all doors will lock and the security telltale will flash.

### Unlock

The drivers door will be unlocked automatically when UNLOCK is pressed on the transmitter. If UNLOCK is pressed again within 5 seconds, after the first time it was pressed, the remaining doors will be unlocked. The dome lamp illuminates for 20 seconds or until the ignition is turned to RUN, with the dome lamp in the DOOR position and all the vehicle doors are closed.

The Saturn Security System is disabled when the UNLOCK button is pressed. If the horn chirp mode is enabled, the horn will chirp twice and the DRL lamps will flash 2 times for confirmation that the Saturn Security System is disarmed.

### Decklid/Liftgate Release

The decklid, or liftgate, will unlock when the vehicle symbol is pressed on the transmitter with the ignition OFF or the vehicle stationary. The decklid will come open when the vehicle symbol is pressed. The liftgate will not come open when the symbol is pressed. The key cylinder button must be depressed to open the liftgate.

### Illuminated Entry

The dome lamp in the DOOR position will be controlled by the doors and the transmitter. When a door is opened, the dome lamp will come on. When all the doors are closed, the dome lamp will stay on for 20 seconds, or until the ignition is turned on.

The Saturn Security System will turn the dome lamp off if the dome lamp switch is in the ON position for longer than 20 minutes without a door being opened or the ignition being turned on.

### Panic Alert (Transmitter)

The red panic button (horn symbol) on the transmitter can be pressed in the event of an emergency. When the RKE module receives the panic signal from the transmitter, it will invoke full alarm. The horn will sound and the DRL lights will flash until the panic button on the transmitter is pressed again, or 2 minutes have passed, which ever occurs first.

### Transmitter and Remote Keyless Entry (RKE) Module Range

The range of the RKE system is about 1 meters (32 feet). It is normal for any RKE system to experience a decrease in range at certain times.

Important: If the transmitters won't work, perform the RKE system check before continuing with the following transmitter and RKE module range diagnostics.

If the transmitters do not work, or if a customer is having to stand closer than normal to their Saturn for the transmitter to work:

• | The transmitter battery may have to be replaced. Refer to Transmitter Battery Replacement .

• | The transmitter may need to be synchronized with the RKE module. Refer to Syncronization.

• | The customer may be too far from their Saturn. Check with the customer on how far they are standing form the car.

• | The customer may be in a crowded parking lot and other vehicles are blocking the signal. Instruct the customer to take a few steps to the right or left if this happens again.

• | The customer may be experiencing radio frequency interference (RFI). RFI is caused by close proximity to radio broadcast stations, motors, heaters, alarm systems, and other frequencies that distort the RKE transmission frequency. Inform the customer and ask them to check for these items in their location.

• | The customer may need to stand closer to their Saturn in rain and snow.

• | The customer may need to stand closer to their Saturn in very high and low temperatures.

• | The orientation of the transmitter may need to be changed. The transmitter may work better held vertically or horizontally depending on the customers location around the car.

• | Taking one step to the right or left may cause the transmitter to work. This is due to the Saturn's spaceframe structure.
