Hi everybody, I'm having some trouble removing the ignition lock barrel on my 190E. The current one is on the way out - the key has to be jiggled around to get the lock to turn, and I've read that this can quickly lead to the lock getting jammed or the key stuck. Therefore I've bought a new (aftermarket) barrel, which I'm trying to fit. My problem is that although I've followed all the instructions in the Haynes manual (i.e. remove trim ring, turn key to position 1, insert home-made tool into slots and pull), it won't pull out. It's clearly unlatching to an extent, as if you then remove the tool and push on the barrel, it 'clicks' back into place, but it won't come out. I've tried gripping the key with pliers and pulling, as well as trying to turn the black shroud at the same time as pulling, but nothing seems to work. Has anyone got any suggestions, before I either take it to a Merc specialist, or try and drill the barrel out? Many thanks, Chris.
