Check Chime Box Module. l only have seen it in Green, but l guess they come in Blue like yours. Try checking it.

it could be the chime module. lts the green box located under the driver's side dash. Located to the far left side, it is connected on a fuse panel. lt controls the lights, interior lights, and of course the chime sound when the key is inserted or lights are on. For the year, additional accessories such as trunk lights and door lock switches, one of the fuses should be checked as it may have blown. Hope this helps

Open the bottom case and unplug the battery. It has a clear tab on it. Pull out not up. Then plug charger in and perform SMC reset. Lights on charger will change from amber to green. Normal. After Reset, should power on. Replace battery. Hope this works. Didn't see date of OP's post.
