2000 Buick Lasabre keys in trunk

try removing the back seat and see if you can get them , Get a thin piece of metal and slip it up behind the lid where the lock is and see if it pops , AAA or locksmith are always an option

I guess you don't have a button in the car to open it

button by the left armrest... provided that u didnot lock the trunk release.

Did you ever figure out how to open trunk? I just did the same thing and I can't get the trunk open.

No I try that

You can get into trunk through back rest of back seat
