2000 chevy impala, trunk wont open, even with the key,fob or button

Chances are the striker is now bent from slamming the trunk with the latch latched. My suggestion is take the car to a competent body shop. They might charge a little for fixing it, but wont do further damage.

Trunk won open even with manual release http://newbeetle.org/forums/new-beetle-convertible/54170-trunk-wont-open-even-manual-release.html there is good info here C24OF

No mention of make/model but does key fob open doors OK? If so it isn't the fob batteries... Could still be a bad button on the fob but it could be a balky solenoid on the trunk latch. Maybe try 12V direct to the solenoid?

if you have onstar that came with your car try to call them .. they can unlock it for you . if you have onstar subscription.. if not you might better call a lock smith..

If it pops the trunk then the unit is still programmed correctly to the vehicle. I would open it and check the buttons and ensure you didn't pinch them and they are still making contact with the pads inside key fob. Probably just stuck after closing the remote.

I work for a doctor and a patient just had this same problem. She had a extra fob in her trunk so we opened the trunk with the key and got her other fob but I am wondering why the key does not fit the lock on the driverside

The buttons on the key have gone out. Check with your dealer for another key fob.

look on the dash at the left side or on the left door

you have a fuse for it ,check the fuse box ,it might not say trunk on fuse panel, you might need to pull those fuses out one by one checking each one to see if blown, if the center between the two sides are broke the fuse is blown, hope this helps you, thanks robert b.

MY 06 Impala tunk would not open using my key fob, or the trunk button on my car . IF you own this vehicle you know that there is no manual keyhole on the trunk. I had to remove my back seat . It is held on by two bolts. In the trunk on the trunk lid is an emergency release handle. Once the trunk is open you need to remove the lock mechanism. Take a test lightand check the wire harness. If you are getting power to the harness and the lock still does not work, you need to replace it. GM wanted 189 for a new lock mechanism, i went to a auto scrap yard. they didnt have an 06 impala, but they did have an 06 malibu. they use the same lock system.the wire connectors for the harnesses look different but it fits fine. the only drawback is my convenience light in my trunk does not work when the trunk is open. only cost 15 bucks for the part.
