suggest you call the AA or RAC...they will know how to open this.

Thank you very much for the advice, I managed to get in - unfortunately didn't read your message until after I had been jump started. What sort of damage occurs with spiking electrical componants ? - in case you you hadn't guessed I know nothing about cars apart from getting in one and driving !

Thanks Liv

Yes I did ! It took me a while to find it though - it is on the front passenger door, if you bend down you will see a little indent underneath the handle, I put my key here and gently prised and the the "cap" came off revealing a key hole. By the way my battery was flat because my boot was not closed properly, I see from searching the net that this is a problem with some Micras - I have to close the boot and drive with the central locking system on, someone suggested spraying the boot catch with WD 40 so I will try that .

Further to my query about the electrics, as I was driving this morning, a beeping started , with no warning light on the console, it was very unnerving and annoying but stopped after about 5 mins, this is why I was concerned that I had done something with the electrics when jump starting , I was fiddling with the radio when this happened !

Thanks for your reply !
