The boot won't open on my W208 CLK. The car starts fine and the door locks open fine with the key fob. Any advice would be appreciated. Thanks.

When you press and hold the boot release button on the keyfob what happens? Do you hear anything whirring or clicking in the boot area?

@Shude,

No, I don't recall hearing anything in the boot area after doing that. I don't use the car going to work. The car's at home right now.

different ways of opening

My car is not a CLK, but it has 3 ways of opening the boot. One from the electronic key, one from a button near the driver seat, and one with the mechanical key.
Are you saying that none of these work?

@blackc55 and @m7m,
I've tried the mechanical key, but it still didn't open. Although I must admit I tried it only once. The mechanical key should turn easily right? The button on the panel beside the drivers seat doesn't work either.

I've had this problem on my CLK. This is how I got round it.

Take the first aid kit out.
You will have an opening and your hand should fit through this.
You will feel a cable on either side, this is the cable that unlatches the rear seats.
Next I got a piece of long 1x1 piece of wood, cut a V at one end.
Now get the V on the cable and push downwards, you have to push quiet hard.

You will hear the latch release and the rear seat should be free to open inwards.

Once you have done this it will give you access to the boot.
There are 4 bolts holding the lock in place undo these and the boot will open. Look for some of my posts I have a picture of this on here somewhere.

Next spend a couple of days freeing the lock with WD40.
I just left mine in oil over the weekend, and by Sunday night the lock was OK.

Hope this helps.

Alex.

spray some teflon based lube into the lock opening, and work the key to loosen it up, it should free itself. These locks do tend to get mucky and stiff as we rarely use the blade key.

I had the same problem with my boot.

I used the same advice as from speedybiker (took a while but worked)

Once you gain access into the boot, try removing the fuses under the boot floor next to the battery (drivers side - card in lid will tell you which ones) and put them back in - this worked for me, may not work in your case, but worth a try, before trying to take your car to bits!!!!!!

My boot wouldn't open with the button next to the gearstick or the remote but opened with the key and i found the switch that turns the boot light on (on the bottom of the boot lid) was sticking. I freed it of with some wd40 and its worked okay since.

Speedybiker's tip works a treat, thanks.

A point to add though is that under the first aid kit there is a hole big enough for your hand (just about, and i've got fairly small hands!!!) but trying to get your 1x1 through here is a pain in the @r$e. Under the foam to the left is another smaller holw which is directly above the wire you need to push. stick your 1x1 through here, push down hard and within seconds, pop, your in.

You're brave to stick your hand in such a small whole. I'll be frightened to get my hand stuck. Just imagine what will I tell the firebrigade when phoning 999 and asking them to free me! :crazy:

Ive finally got into the boot. Now how do i get the boot to actually open? All the fuses are fine, Ive tried takin them out and puttin them back in, but no luck!
Im confused now??

I had similar problem. Is your third brake light working and your numberplate lights? If not this suggests a break in the wiring somewhere of a bad earth, just take it to a specialist and have it checked. This was the fault with mine and it wasnt expensive to put right...
