Re: 146 changing Ignition barrel
If you have been opening the car by remote then can you jack the front of the car up to get under and release the bonnet so that you can charge the battery?
Otherwise I would recommend just calling out a locksmith to open the car and remove the broken portion of key from the ignition barrel on the same visit. If my memory is right the one on Wellingborough Road is called Benns Security. If he doesn't do auto stuff then he should be able to recommend someone that does.
Jai still had the lock set when I spoke to him last week, he has a post for it in the classifieds section.
It sounds like Barry does this for a living and knows what he's on about. If you can't find a local locksmith up to the job or the call-out cost is prohibitive then if you take the ignition lock off you could send it to him for him to remove the old key and make you a new one. To use the car temporarily you can just pop a self-tapping hook into the steering column plastic shroud to hang the electronic part of a key on and turn the ignition with a screwdriver.
To get at the lock you'll need to remove the platic trims on the steering column, don't miss the allen headed bolts tucked away that hold on the top half or you'll snap the lugs. To remove the sheer bolts I drilled small holes around the sheer flange then chiselled into them so that it was easier to drift the bolts around and unscrew them. It's almost impossible not to mark the lock surround doing it but it's hidden when you put the covers back on.
Good luck, if you're really stuck and don't know where to start then I'm in Kettering next Monday morning if you genuinely need a hand let me know.
