SOURCE: Mercedes-Benz 230clk coupe 1998 with dead battery

I had same problem with my 2002 CLK430. Dead battery with car locked. You can't open doors with the mechanical key (inside remote key), as windows need power to slide down slightly to allow clearance, so you can't access the hood release. The answer is to insert the mechanical key in the key hole for the trunk (boot). It will only go in one way, with the slightly larger grip part down. I found it easiest to turn with a pair of flat nosed pliers. Turn counterclockwise to the left to to the 11 o'clock position. Then push the release in and the trunk will open. Battery is located in the right rear quarter under the flooring panel that also covers spare tire. Hook up charger or jumper cables and power will come back on, as will alarm. To disable, just push the unlock button on the remote key. You should be good to go from here!

Flat battery no entry

you can still open the boot and the drivers side door with just the key even if the battery is flat if you have taken the lock off the car you will have to smash a windo to gain entry or a lock smith but smashing the glass will be cheaper to replace than a locks smith i think

I inserted my key to the lock and the key could not turn aroud to open the door. I assume that it is the door lock is jammed and do not know what to do.


If the driver's lock is jammed, gain access to your vehicle from one of the other doors.

If neither of the door locks allow entry, then it's possible your doors have been "dead-locked" via a remote entry system or similar.

You need to either unlock via remote key entry, or via another door.

Car battery flat stopping entry to car using key fob no external lock to allow access using key how can I gain entry to car.

I've never heard of a car without at least a key lock on the driver door. Unless it's a custom car, but they usually have a hidden button to push to open the doors. The only way to get in, other than calling a locksmith or breaking a window, is to use a "burglar bar", or as some call it, a "slim jim", to try and hook the opening or door lock mechanisms inside the door.

Dead battery, can't open doors

If you have the keyless entry system, you either have a dead battery in the car, or in your key fob. Regardless, you can gain entry to the vehicle using the emergency key concealed inside your fob. Press the narrow button near the metal end of the fob to separate the parts. They metal piece has a key attached that fits into the lock on the driver's door.
