2014 impala battery dead and there is no place to unlock with a key

Some makes and models you can use charger at the bat terminal on starter motor. Of course, I can't see anything from here.

2014 Impala key fob has a button you push and a door key pops out, but you must remove small plate to right of handle then use door key to unlock. Jerry S

Call Chevrolet automotive repair department

You could also get a locksmith to come out and open it for you

Using the key fob works to remove the side piece on the door handle. Thenuse the door key to unlock the car!! YouTube it if you are confused..that's what I did!
