Electric motors rarely need lubricating and when they do it must be done sparingly and with great care and the correct lubricant used due to the possible safety dangers, including fire..
Often an electric motor is integral with a gearbox which also tends to be prefilled with whatever lubrication it needs for it's lifetime. Sometimes, but rarely, this will need attention and a little further lubrication. Mostly this is the result of a necessary repair or adjustment.
There needs to be a compelling reason to open such a gearbox and again the correct lubricant must be used and then the integrity of the sealing maintained.

You have probably set your scale to kilogram and not pounds. There should be a button to set this underneath the scale or even a reset button to reset the scale to its original settings.
Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site.
