I locked my keys in my car. how do you break into a 97 chevy lumina?

This just happen to me you need a wage and a coat hanger Use the wage to make a cap between the door and the frame of the car to slide the hanger into the car using the hook on the hanger, hook the Manuel door lock and pull

If you do not have any tools, take a piece of wood and cut a long slightly sloped wedge. put the wedge between the top of the door on the latch side up by the roof. use a hanger that is made into one piece and go into the compartment through the space made by the wood. It takes some practice, but use it to push the up button on the power lock. I am pretty sure all the Lumina's had power locks.

Hope this helps.

If you have an Autoclub membership or insurance company premium policy they will pay for a Locksmith to come out. They are usually very fast. Police and wrecker drivers carry slim-jims for the same purpose.
Last, you can get the VIN# off your car papers or front window ID plate and ask the dealer if they can cut a new key.

Slide something between the window pane and the door and fish around for the lock mechanism and pull upwards
