Heeelp - locked-out + no battery connected

[mpatton]

Hi All,

CLK 230 (1999)

Here's my predicament.

I removed the battery to recharge it. I inadvertantly closed the boot. I then discovered that the manual key will only go two-thirds of the way into the boot lock (though it does lock/unlock the doors). I have sprayed all sorts of releasing oil into the aperture but to no avail.

Does anybody know of any secondary electrical points under the bonnet where I could connect the battery in order to use the electronic key to open the trunk?

I take it you can get into the car,if you can then you can buy a unit or borrow one that plugs into the cigarette lighter and connects to a battery,this will give you power to open the boot

Hi Snap-On,

That sounds perfect - could you tell me where you get them. I have just tried searching on Google and failed miserably.

Cheers, Mike

Snap-On,

Looks like I'll be up and running on Monday as the EBay link is a shop a few miles from where I live.

Thanks again, Mike

Battery

Normally there's a battery live going straight to the starter motor. So you could take a positive jump lead from the battery live to the big terminal on the starter and then a negative to the chassis

As ever with cars and car batteries, handle with care, done at your own risk, etc

I was going to suggest that,but trying to fit a jump leed to the starter would be difficult as there is very limited space,and as you say do it at your own risk..

There is normally a connection point under the bonnet for jump starting the car but can?t remember where exactly it?s located

Hi Guys,

I have just found out that there *is* a connection point under the bonnet.

Here's the link for future reference (with photos):

A quick update for anyone who is interested?

At the 11th hour I got cold feet about connecting the battery under the bonnet (hood) and decided to call my local Mercedes dealer to double-check the procedure. They suggested that I should be very careful as the battery leads in the boot (trunk) may be touching the metal work. And if it was I should expect to hear a loud bang!

They suggested that I call Mondial Assistance - the 30 year Emergency Cover for Mercedes. As I couldn?t remember in what state I had left the disconnected leads, I did this. When you buy the car, the Mondial service is sold to you as the ultimate emergency service for your vehicle, the ?help you out no matter where you are in the world? service. So when I told them the problem with the valet key not operating the boot lock ? they promptly, and very coureously, replied ?that is not covered? and refused to help any further. Thanks Mercedes and Mondial ? nice to know I can rely on you when I need you.

Anyway back to my problem. I noticed that one of the rear seats was not fully locked into position, so with a bit of luck I gained access to the boot via the passenger compartment. I then managed to release the other seat back, and remove the cover from the boot floor ? exposing the battery leads.

Hey Presto! Connected the battery via jump leads and popped the boot.

The moral of this story is ? check your keys work BEFORE closing the boot and DON?T ASSUME YOU CAN RELY ON MONDIAL ASSISTANCE for help.

The one happy and cheerful point to emerge from this is that I now know that I can rely on individuals like you guys on this forum to offer advice and help whenever you are able.

Thanks again,
Mike

The one on the 210 was over the N/S wheel arch - a brass pin in a black plastic box for + and a brass pin on the wheel arch for the -ve - not seen one on a c saloon though so may not be on the clk either. I suspect they put it there when the battery is under the rear seat. They probably reckon that if its in the boot, its as accessible as when its under the bonnet.

Hi

I've got exactly the same problem (boot key goes 2/3 in; need to get power to unlock the boot so that I can get my battery in!) with my CLK Cabrio. Did you get this sorted and if so how?!

 

[television]

With a charged car battery (not charger) join the +v to the large terminal on rear of starter, and - to chassis, that will power the vacuam pump to unlock the boot, do not use jumper leads and large crocodle clips for the +v connection unless there is no chance of a short. Let me know if you cant get to this terminal.

Thanks for the quick reply Malcolm. I take it the alternatives described above wouldn't work then? e.g. connecting a supply via the cigarette lighter? or connecting positive to the post on the near side wheel arch (there's a plastic covered post with a couple of cables attached but there are no +ve or -ve markings on it. It looks like an earth point but can't be sure)

 

[cyps]

teminals under the bot are generally where you would expect to find a battery located on the passenger side in my 210 just two spikes one marked + and other -

It may work via the cigar lighter, the radio shares the same lead, the key would have to be turned to ignition to 1, the snag will be if there is a relay on this line. I do not know about the post near wheel arch, the cables there may be on an insulated post, but don't know.
Another point would be the side lamps fuse, turn the side lights on and with a thin wire put it in the hole in top of the fuse, you only need it there long enough to run the pump to open the boot. if I think of something else I will post it.

I spoke with Mercedes about the post (two different dealerships). I finally got a call back saying they think the post approach should work. Will try it at the weekend - fingers crossed!!
