Unable to access battery to recharge it because central locking system inoperable due to flat battery

A flated battery would not affect the central lock. Mostly it is due to the improper fitting. The door locks are operated by a solenoid in each door. First check the fuse of the central lock. The fuse boxes are in engine compartment and inside the car under the steering wheel panel beside. In most cases, it is the fuse stall the car. If the fuse is OK, then check the electrical continuity. If you are not car machanic, let the proper car electric specialist to do it for you. For them, it is a very easy and quick job to do. Aso ckeck the battery in the remote if it is porperly fitted. You have to buy a Haynes Workshop Manual for Camry 2007-2011 PN 92009.

Get a battery charger hooked up so enough voltage to do this .

You have likely lost programming, the dealer must reprogram the system for you with a special scanner.

you may have to get a locksmith to open the car for you.......cheers.

Not 100% sure on that vehicle but using key to lock and unlock drivers door will quite often shut it off.

you will need to reprogram system

try locking and unlocking the car with the key 3 times slowly ,other than that i have no idea ?? another trick is to disconnect battery and join the cables together for a few minutes to discharge any capacitors that may be holding a charge in the computer..Only other thing i can think of is the main dealers who have the right connectors and software to re set it all .sorry i havent been of any help

Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle. Unfortunately, you'll find the system which controls the door locks is the ETACS Module (which also controls many other circuits which would become disabled if you pulled its fuse).
I've run into the problem you describe. Frequently it turned out to be a bad switch in the driver's door lock/unlock actuator.... Unless I diagnose the problem myself (or some other qualified technician does it), it could be something else entirely.

the key should open the door without any batt power central locking is batt , the key should open both front doors!!owered so it should not be a problem !

Your key should work manually (without battery) on at least one door or the trunk/hatch. Otherwise the world would be filled with abandoned hyundais with flat batteries and no way to get in! Try the passenger side door; don't expect to hear the central locking relay, but if you turn the key far enough, that door should open.
