Thanks guys for all the info managed to get into the boot yesterday. I still have a problem the key doesn't go in the boot barrel i got some wd40 onit but still doesn't go in any ideas? I really don't want to change the barrel
Flood the lock key hole with the boot lid IN THE FULLY OPEN position, this lets gravity give a helping hand to spread the oil around the lock internals put the Red straw of the WD40 aerosol right into the key hole, squirt every hour and try with the key… keep the boot lid open all the time.

The barrel can be removed from the boot lock assembly and taken apart and cleaned and reassembled though it is fiddly and will need to go back "exactly" the same otherwise the key won,t fit.
I,m sure Dec put a load of pics up showing what to do.
Once you have it freed up put one of those lock blanks (the type that goes into the front door lock) in the key hole to stop it crudding up again.

It’s always best to try the easy way first, with oil, if the WD40 doesn’t work then you will have to take the lock apart.
Split the lock into two halves and put up some pictures, if you can get the key blade to fully enter the lock keyhole then you might be able to free up the lock (when its split into two halves) without the need to dismantle too much of the lock barrel part.
Stick with the WD40 for as long as you can, you might get lucky.

I have exactly the same thing with my 43 key only goes in about half way, and my C230K the key goes in but will not turn. I haven't been brave enough to follow Decs thread, as I said it looks well fiddly.
It’s a fiddley job alright, it’s best to try first to free it with oil, over time and with the boot lid open as suggested in post #22 above.
If the key blade won’t fully enter the lock then one or more levers in the barrel are seized.
If the key blade can fully enter the lock then none of the levers are seized, the problem is further back inside the lock.

+1 on the fiddliness. Having spent months trying to get some joy out of WD40 I was forced to go down the route of taking the thing apart. It took ages.
You could try canned air, into the keyhole, the thermal shock might free up the lock… Canned Air "Expirements" - No life and boredom - YouTube ...thick gloves needed.
