Will a slim jim unlock the door to a 04 gmc sierra

Most lock out companies use a long metal rod that is inserted through the top of the door and is then used to push the power door lock button or the lock button. If you gently pull on the top of the door and insert a wedge to keep the door ajar slightly, you can use a coat hanger and manoevere it to touch the door lock button

Slim jim won't reach it because of how it has to be curved to get to the latch. You have to pry out the top of the jam/window. Then reach down with a close hanger to unlock the door. Don't push against the top as it will bend. Pull the window/frame out. It will bow out some. Put your knee in the middle of the door and pull the window/frame back into place.

Slim Jims do not work very well. There is a new tool that is heavier than a hanger. You sneak it down between the door jam and door frame and either push the power door lock button or pull the unlock knob in the door panel to unlock the door.

have you tried to use the outer door handle..if not you may need to use a slim jim door tool..

First, align the slim jim with the lock and push it inwards in the direction of the keyhole when the lock is visible - pull the slim jim upward slowly until the door unlocks.

I had a 95 model and I bought a yard stick, pried the door open a little at the top and slid it down to the power lock button and unlocked it.

A lot of newer cars can't be opened with a slim jim anymore. A good kit uses a small bag that inflates with air to allow a long rod to unlock (electric door locks) These work much better.

a slim jim is not a good ideal to be using in todays cars and trucks with airbags everywhere and wires inside doors..call a pro and if he pulls out a slim jim send him packin...there a re far better tools to use than a slim jim

call a locksmith and ask. some require a specially designed tool similar to a slim jim, that a slim jim will not open.
