Oh Bugger! (...and help!!)

[one trick phoney]

I was putting new shocks on the front of the 200E today and eventually (with one side done) the rain got the better of me. In my haste to get everthing away I have locked my keys in the boot.
The Central Locking is disconnected right now too.
I do have a spare that was cut from the original but that does not open the boot. I don't really want to force it.

Just to make matters worse its backed on to my Mums drive way and is about 4 inches from the closed garage door.

Does any one have any ideas of how I can get in the boot with out resorting to (too much) violence?
