Your car battery in the trunk is probably dead

No everything is good on the battery I can unlock and lock the doors fine when I'm inside with all doors closed and I replaced the batteries in the remote.the car still won't unlock or unlock with remote and it won't turn in the ignition switch or recognize the key

Dead key fob perhaps. Do you have another one to try?

Did some form of trauma happen to key? (tour of your clothes washer, dropped in puddle, dog ate it, etc)

You are disclosing 2 separate failures here, IR and RF both dying at same time, unlikely.

Most key failures are one or other.

Is possible your EIS is failing or other DAS related system no longer liking key.

2nd key to test would be ideal. Might order one to get answer, but be ready to get EIS replaced/repaired if 2nd key also not working.

Only having one working key is recipe for distress/disaster.

Does red light show on key?

Do you hear little "whirr" sound when it goes in EIS?
