basically my mom went on a business trip n sent her car out to get detailed n cleaned. the people drove it back and left me the keys (i wasn't home at the time). I wanted to drive it back into the garage but the car wouldn't unlock. so i manually unlocked it but no lights came on. i tried to start the engine but nothing happened. there is absolutely no electricity happening...and it has nothing to do with a possible audio system lock. how do i fix this? because i'm pretty sure it's in some mode that the person who 'delivered' the car to us put it in.

Try moving the shift lever back & forth a bit while rocking the car forward & back. It's probably not completely in Park & won't start until it is.

Sounds like the battery is dead. The detailers may have left a light on inside and after they left it ran the battery down.

Use the key fob (little clicker) to unlock... it will activate in order to start.

- Good Luck!
