just pulled the trim off, a few hassles but i got there, only to find that there isnt a central locking mechanism/wires etc..!!! grrrr. tried turning the key a full 90° and she wont go, only gets to 45 and feels as far as it will go but still doesnt engage full lock no matter what i do. oh well, my main mission was to suss out the c/locking, the other issue with unable to unlock from the inside etc can wait. a bonus was i got to see the type of speakers the previous owner put in, 6inch kenwoods. not bad but could do better. one thing i did find but not sure if its normal is like kind of a loose end of the rubber seal on the inside near the mechanism, investigated it and it isnt interfering with the lock so that isnt to blame. anyway, thanx for the replies, i'm sure i'll have something else to ask later on down the track.
