Is there are key hole? otherwise do the back seats fold down? Though if the battery is in the trunk from teh factory, they usually still run terminals up to the engine bay

    If you dont see a place to put in your key in the trunk area thn try this:
    If there isnt enough power left in the battery to open the trunk using your remote, or your remote is dead and you dont have another one you can do this:

    Get a friend or neighbor (or call roadside assistance if you have it, AAA, Factory Warranty, etc) and have them come and jump start your car from the jumping leads under the hood and pop the trunk.

    If you look in your owners manuel you will find directions for jumping your car, though it is not somthing I normally recommend as it puts a tremendous strain on your car's electrical system.

    In your owners manuel you will find 'how to jump start your car' the basics are there is a RED plastic cover with a big + sign on it, this is your positive, pull the cover up and you will find the positive jumping point or bolt, hook the postive jumper cable up to this, you will also find in your manual a NEGATIVE jumping position reccomended by the factory, which can be pretty much anywhere on the engine block, but use the recommended jumping position in your manuel. Connect the negative.

    You will know if you have a 'good' connection almost instantly as your vehicle will start to chime and dash lights will come on, etc another way to chck if you have a good connection is to turn the headlights on so you dont have to kep running back and forth to check and see if your dash lights are on, it's a good idea to turn the headlights on using the manual override, and to turn OFF all your accessories INSIDE. (Your radio, A/C, etc) as it is just consuming power you do not have and will take longer to jump.

    Turn the key to the ON position, and now press th trunk release. If you want to check and see if your having issus (which for a 2008 you may nd a battery already) jump the car and let it run. Chck to see if you accidently left on an interior light or accessory, while these vehicl are suppos to have run down protection, it dosnt always work. I can't tell you how many times my battery has bn draind because my 6 year old left on the map lights in th back or some other accessory.

    If you can bring the car to Autozone, or a Part center, they will load test your systm for free, checking the battery and alternator in the process, if your alternator is no good a new battery is not going to help you. If th vehicle is under warranty, they WILL NOT cover a battery as it is considered wear and tear, but they will cover a alternator or other problem in the charging system, so before you go and spend $100 at walmart on a guess - have the reason for not having any 'power' figured out by a professional. Auto Zone and other natioa chains offer this service for free, they have the test equipment and can pretty much tell you right on the spot if you Battery is no good or if it is something else, and the service is free (even though I usually tip the guy or girl $5 - it beats paying Cadilac's labor rate of a 1 hour diagnostic charge of $95.00 any day).

    Please let me know if this has been useful and if I have helped you. If you do not have a owners manual I can try to find out the jumping point under the hood as your battery is in the trunk or under the back seat dependng on the make and model, which is exactly why they (GM) put this jumping pst within the engine compartment, and it is also ill advised to jump directly to the battery anyways.

    Just DOUBLE CHECK your leads, and make sure your going Negtive to Negative and postive to positve, if you criss cross you'll fry everything and it will be a very expensive paperweight.

    Best of luck

Hello: On the rear bumper, driver side lower portion you will see a square which you can flip open with the key you have. Once open you will see a lock cylinder, insert the key and turn. That will open the trunk. Inside the trunk you will see a handle, pull it and it will open the drivers door. That should do it.

My keys are locked in trunck

get a spare key to open the trunk, or if there is a button for opening the trunk, push it. Sometimes this won't work, though, because some buttons in Cadillacs only work with the ignition on or 15 min. after the ignition was turned off and the doors are not opened.
