There are two possible problems: 1) the key can't turn because of the insides of the cylinders aren't allowing it. 2) the key can't turn because of the rods and locking mechanisms are jammed. It sounds like you have verified that it isn't #2. However, you could get in the car, lock it and roll down the windows, and reach through and try to unlock it while you watch and try to assist. #1 can be because of corrosion in the cylinder, worn key, broken key, or foreign matter inside the cylinder. The first thing to do is to make sure that your key is in good shape-- not worn, not bent, broken or breaking. Here are my thoughts. You know that it has been modified from the original; do you know if it was professionally done, or by owner? I have seen/heard that some of the early cars were modified by owners very poorly. Unfortunately, you probably will need to have a lock professional look at it, and very probably keyed correctly and fresh code-cut keys. --- gzapf <x86Daddy@xxxxxxxxxxxxx> wrote: > > > > I have an early VIN car that has the later door > locks that match my > ignition.
