You definitely need to purchase a battery maintainer, if you leave the car sit for weeks on end. I leave my car unlocked in the garage all winter on a maintainer and have never had an issue with the remote all these years...not sure why you feel you need to lock it. Modern tires don't flat spot (unless you lock them under braking). Very common for the pads to adhere to the rotor...unless let sitting for years, this causes no harm.
