I need to lock the door from otside on left side and inside right and im confused which one have to buy .

You can purchase one of our smart locks, as you can do the calibration.

Does this work with the previous 2k doorbell?

It doesn't work with the previous 2k doorbell

Does this have a motion sensor that automatically turns on camera and alerts phone through messaging ?

The Smartdrop box when it's set up the camera will activate when it detects someone approaches but it will only record video if you have the Eufy Homebase. Without the Homebase, you will only get a notice from the phone app that the Box was OPENED & CLOSED...But No Video.

Does this work with E340? Or will E340 battery be released soon?

No. E340's battery will be released soon.
