How to disconnect a car battery before going for a vacation - so that central locking is still active?

the locks are not electrically operated the central locking merely opens and closes them disconnecting the battery when the doors are locked will leave them locked and even more secure since then only a key will open them|||If you're not going to be on vacation for very long, say over 30 days, I'd leave the battery connected. The reason for this is that the computer in your car will have to "relearn" your driving habits all over again once the battery is reconnected upon your return. All electronic memories like your radio functions and any other settings will have to be reprogrammed. It's not that big of a deal, but there's really no purpose in disconnecting the battery for up to 30 days. The car's electrical systems will not draw much energy from the battery. Any alarm system you likely have on the car will also not be working. The main thing is, enjoy your well deserved vacation and don't worry about the battery running down. Good luck with your decision!|||There is no way you can accomplish this unless you rewire the locking mechanism to the battery separetely|||Just take the negative (black) cabble off.. But make sure it isn't going to ground out on anything, very important.. But yeah you cant keep just the locks powerd up, use the key.|||You can't. Central Locking needs power to function|||battery must be connected of else central locking will be disabled|||Just take off one or both cables and use the key to lock the doors.
