My trunk wont open with the keys or automatic button

Luggage Compartment Lid
The luggage compartment lid module receives a voltage signal from the driver door module (DDM) when either the button on the driver door trim panel, the keyless entry keypad, or the transmitter is pressed (twice on the transmitter). Voltage is then supplied to the luggage compartment lid latch, opening it. Using the luggage compartment lid key operates the latch mechanically, resulting in manual-only operation of the lid. There are two switches in the latch. One is monitored by the luggage compartment lid module to sense if the latch is closed. The other switch in the latch is monitored by both modules (LCM and luggage compartment lid module) and is used for disabling the anti-theft system, which is contained within the LCM. The luggage compartment lid module powers the lid motor to move the lid to the full-open position when it senses the latch has been opened. Optical sensors within the lid motor are monitored by the module to determine when to turn off power and which circuits should be powered or grounded to the lid motor. When one of the buttons is depressed with the lid open, the DDM sends a signal to the luggage compartment lid module which powers and grounds the correct circuits to the lid motor and lowers the lid until the latch closes. The module senses the latch closing through the lid latch switch that is monitored. At this time, the module powers the closing motor, slowly pulling the lid to a fully closed position. Two switches within the closing motor are monitored by the module to determine when the closing motor is fully down or up. The module has a vehicle speed output (VSO) (circuit 679) signal that is used to shut down the system if there is a VSO of approximately 5 kph (3 mph) or more. For diagnostics, the module uses the ISO-9141 circuit 70 that is included in the DLC (data link connector). Whenever battery power is lost to the luggage compartment lid module, luggage compartment lid motor or the luggage compartment lid closing motor; the system must be initialized.

NOTE: The luggage compartment lid motor is equipped with an optical sensor that the module uses to determine if the lid is closing on foreign materials based on lid speed. If the module detects this occurring, power and ground will be reversed to the lid motor and the lid will open.

1. Verify the customer concern by operating the luggage compartment lid using the four different methods (driver door trim panel button, transmitter button, keyless entry keypad and key) to duplicate the concern.

1. Visually inspect for obvious signs of mechanical or electrical damage.

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. Verify the two grounds (G204, G401) are clean, tight and free from corrosion. Remove and clean to make sure.

1. Monitoring the PIDS in the luggage compartment lid module can verify the DDM is sending the lid-open signal to the lid module. They can also be used to determine if the latch switches, the lid switches and the lid motor sensors are all providing the luggage compartment lid module with the correct and necessary information to operate the system. The VSO input can shut the system down if there is a signal indicating 5 kph (3 mph) or more.

1. If the electrical lid operation is ok, but the key is ineffective, refer to Section 501-14 .

1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) located under the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the program card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.
   • If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.

1. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with:
   • CKT 914, CKT 915 or CKT 70 = ALL ECUs NO RESP/NOT EQUIP, refer to Section 418-00 .
   • NO RESP/NOT EQUIP for luggage compartment lid module, Go To Pinpoint Test A .
   • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the luggage compartment lid module.

1. If the DTCs retrieved are related to the concern, go to the luggage compartment lid module Diagnostic Trouble Code (DTC) Index to continue diagnostics. For lighting control module (LCM) concerns, refer to Section 419-10 for a complete DTC index.

1. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart.

Victoria, Fold down rear seat back, to access trunk space. Your vehicle is equipped with a release handle that provides a means of escape for children and adults if they become locked inside the trunk/luggage compartment.The handle is located inside the trunk/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.
Check the attached links,instruction and guides, Good luck

Ford Taurus Owners Manual Interior luggage compartment release Locks

Ford TAURUS Owner Manual Trunk Release

Ford Taurus Now with an anti kidnapping trunk release funny

maybe the locking mechanism which latches the trunk closed needs to be adjusted a little more loosly (move the latch so that it engages sooner as you close the trunk) - do this by loosening 2-3 bolts to move the latch.

Turn on the radio so the battery is engaged, or turn on the engine.

2 Fold down the cargo partition in the trunk and lock it on both sides. If the cargo partition is not down, there will be no place in the trunk to store the convertible top.

3 Press the convertible button forward to open the top. It's located under the circular control button on the consul. The button has a picture of a window with one arrow pointing up and another pointing down.

4 Pull the convertible button backward to close the top.

5 Use your key to open or close the top when you are outside of the BMW but still close to it. Press and hold the arrow button on top of your key to open the top. To close the top, press and hold the Lock button. The car does not need to be turned on to operate the top with the key.

Go to the trunk and put your key in and turn it all the way to the left and remove the key. This way by pushing the button at the trunk it will open, the trunk will lock when your doors are locked and the trunk will unlock when the doors are unlocked allowing the button at the trunk to work at that time. I'm not quite sure if your system works that way, or Try pushing the button that opens the trunk down by the hood release latch, or, you should have a remote key with the trunk open button on it, it should have 3 buttons, one is lock, one is open the car and one is open the trunk, if you have the automatic opening trunk, this should be the same, and to close it, just press the lock button and it should automatically go down again, as you did not specify what year yours is, one of them should do the trick...hope this helps

Try unlocking trunk with emergency key,inside remote

It needs to be reprogrammed.

There is a procedure to this.

Stand close to the car, hold down the open and close knobs for about 10 seconds. Press them at the same time for 3 seconds; then press the open button as the car opens.

Rate this.

have you tried pressing the button that opens the trunk... It is usually in the glove compartment or sometimes it is a lever to the left of the drivers seat

when you hit the key and hear the motor push down on the trunk a few time. quick and hard like you are doing a cpr chest compression. I know it seems counter intuitive to push down to open the trunk but it just may get it un stuck. I know someone who had to do this every so often to get in their trunk
