Has anyone attempted to change the lock on the gas cap to match their car?
My cap is looking pretty bad and I have another one but would like to keep its locking capabiltiy with the car's key. I plan to destroy the old cap by removing the plastic around the lock and extract the lock if there is not an already tried and true method, maybe that will reveal a means of removing lock from new cap.

I haven't but I sent one door lock to 928intl.com with the key that went to it, as well as the key I wanted it re-keyed to. They were able to do so, by changing the internals of the lock. I would suspect the gas cap would be the same.

Since I had a replacement, I decided that destruction of the bad cap would not be a loss so I took a hook which I could insert between the red cap and the white center and then twist behind the white center. By applying a bit of pulling power the first tab moved and repeated effort did the same as the first releasing the red cap from the white center. The locking mechanism sits in the white center and is held in place by the red cap. Just a matter of replacing one locking mechanism for the other and snapping it back in place. You can see in the picture why I wanted t rplace the cap.
