I am looking to sell my Ka Studio (boasting roll down windows, manual mirrors and manual door locks!) and I have put too much graphite powder in the boot lock as part of maintenance. I have attempted to use a cotton bud to get it out (which has worked before) and now the lock is full of powder and cotton bud heads; the key just about goes in but doesn't turn and open.
Are there any remedies anybody may suggest? The person looking to buy isn't that fussed but as the car has been so reliable I wanted to give it the dignity of a working boot door and increase the selling price.
