I will try the penetrating oil if i buy the car. I cant try the central locking because the knob is missing! I am a bit to large to get in through the back seat. The key does have a red dot (someone asked) I guess I could have a locksmith get me in through the trunk if I have to.

Then, slip the key into the hole and use a little force in each direction. Repeat the WD-40 treatment, push the button in a few times and then try the key again. Make sure you get it into the hole up to the stop. it is entirely possible the lock is just full of crud and is sticking. This can make it difficult to turn at all, even when the key is all the way in. Also, do the vacuum locks (central locking feature) work at all? If the engine starts and the battery is charged the vacuum pump should run the locks and unless someone specifically locked the trunk out of the system, it will unlock when the locks are cycled. Which should work by sitting in the car and pushing the driver's button down and then, once all the doors lock, pull the button back up. All the doors should unlock, including the fuel filler flap and the trunk.

Give it a shot and let us know. Mining your way in through the back seat might also be possible, but only as a last resort. Jim
