Battery for 2005 lincoln ls is in the trunk and we cant open the trunk. (battery is too dead to use the keyless remote pad on the driver's door) Is there anothe way to boost this car and get it running? The ignition key will not topen the trunk (??) but we can get in to the car.

Read my other post to your other question

If the doors are open,drop the back right seat back,
& crawl into trunk & pull the yellow release tab

OBD2 Vehicles do not use the lighter for battery voltage,
that was obd 1 systems ,the power is in the diagnostic connecter
by your right knee,need adapter to use battery KAM memory
back -up

The seat may only be released from the trunk--.have to check my 2004 LS

Can not be done, in order to do anything code is needed, as far as changing the code i think you may need to replace the module.

Lincoln has always put the code in the trunk on hinge, open the trunk and look at both hinges, there should be a small sticker with the door code. good day.

Try using the Keyless Entry Pad

If that won't open the drivers door,
then you will need a scan tool, to see
if it can comunicate with the DDM -
Drivers Door Module.

That may be a possible problem, if
everything else works

You could raise the car up

Put your small battery chargers red clip,
very carefully on the big cable, on the starter solenoid stud

Black clip to any metal ground,engine bock
casting rib,bracket etc

Then plug in charger and try your key FOB after
about 5 or 10 mins,to open trunk and doors

Trunk reless relay ! Which year is right ? at the top is shows 1992 Buick . An it also has 2005 ? Which is it ?

security module in the trunk ???? There is no security module in the trunk . What light's come on by them self ? Park lamps , headlamps , brake lamps ,turn signals etc.... The module for anti-theft is under the right hand side of the dash . The remote keyless entry module is located in the trunk. Is this the part you hear clicking in ?
Door Lock Control Processor, Electronic NOTE: The electronic door lock control system will not function when the ignition switch is in the RUN or ACC position.
The electronic door lock control processor:

• is located on the LH side of the luggage compartment.
• contains a radio receiver that receives a signal from the keyless entry remote transmitter (15K601) through electronic door lock control processor antenna, and sends the appropriate command to the power door locks, the horn relay, the indicator flasher, or the anti-theft warning system.
• is equipped with a battery backup which holds the programmed code in memory in the event the vehicle battery is disconnected.
• • Doors Do Not Lock or Unlock Using Keyless Entry Remote Transmitter
  • Circuit.
  • Electronic door lock control processor.
  • Keyless entry remote transmitter.
  • GO to Pinpoint Test B .

No idea what your question is, but if you are asking what the pad on the door is, it is a code pad to unlock the doors, open the trunk etc. I don't know if they still do it, but Lincoln use to put the base code on the trunk. Look around for a tag stuck to the trunk arm, or trunk lid. When you enter the code it unlocks the doors and if you push other #'s after the code it will open the trunk, turn on lights etc.

Hope this helps.

Other than take it to a dealer to have the factory code pulled, the only place I know of that Ford lists the codes is on the module itself. Your LS control the remote keyless entry from the drivers door module which is located in the drivers door. You will have to remove the door panel to find it. I would take it to the dealer, from my experience the door module does not always have the number on it and the door panels are very easy to break when removing.

does trunk button work? panic button?
here's 2003 info:

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter.
• Driver door module (DDM).

• Go To Pinpoint Test G .
