Mercedes SL 500, 203 model: The boot will not open by central

Resolved Question:

Mercedes SL 500, 203 model: The boot will not open by central locking or manually with the key. It turns - stiffly - but seems not to engage with anything.
I think I need to get at it to replace or clean the physical lock, but to do that I need to get at it, which means, erm, opening the boot!
Is there any way to get at the mechanism from outside? All I can think of is to remove the number plate lights, or else drill the lock out.
Help!

Stan :

Hello,
I suggest to try resetting the central locking by removing it's fuse for 10 minutes ( fuse 71) in rear stowgate compartment fusebox. CLick here for fuse assignment

Stan :

This can make the boot to unlock centrally

Stan :

If this does not help, next step would be to drill out the lock cylinder.

Stan :

best regards,
Stan

Customer: Thanks, Stan.
Customer: I'll try that tomorrow if I have time, or Saturday. , and let you know how it went.
Stan :

No problem, get back to me whenever it is convenient for you.

Customer:

Thanks, ***** ***** try that on Saturday and let you know how it goes.

Customer:

I also heard that you can get at the lock from outside if you remove the number plate lights and then the brake light. Thoughts on that?

Stan :

I personally cannot imagine this to be possible. We had to drill out the lock cylinders.

Customer:

Yes it does sound unlikely - more a jib for a gyneacologist!

Customer:

Thanks anyway - I'll let you know in due course.

Stan :

Will be glad to assist you further. Have a nice eveninig.
