Locked out of C43
Hello all. So my c43 has been sitting for over a month due to a moderate misfire and I haven’t had the time to work on it. When I went to unlock it today the battery was completely dead. I can open the drivers door with the manual key but it wont turn in the key hole to open the trunk so I can jump start it. Does anyone know any other way to get the trunk open? If not I guess I will have to call a locksmith?

That's the access to the 12v that goes directly to the blower motor. You can hook up a jump box or jumper cables directly there which will give you enough power to get in the car and use all features, but don't try to jump the car from there. Instead use it to get the trunk switch to work then jump the car normally.

I use this method, except that instead of using a battery I hook up my battery charger, pop the rear hood and disconnect the charger. Takes all in max 5 secs. Bingo!

Another way to do it is by using one of those chargers that goes through the cig lighter. Dead battery's in a C43 is common at my house, I know have a trickle charger on it, had to take the bulb out of the the trunk.

Can I ask why it's common? I have a year old battery that if I don't start the car within 3 days the battery goes dead. And this is happening in summer. I don't believe I have anything pulling juice.

But the car also drains the battery quickly if left sitting.

My 43 can sit for several weeks with no major loss in the charge of the battery.
