79 280zx Fuel Cap

Your gas cap from a donor car that's why your key is not working.

That figures.

you can take them apart and get the lock redone to fit your key. Assuming you have a COMPETENT locksmith in your area. Not Home Depot, Walmart, hardware store. someone with a sign that says Locksmith. works better if you know your key code. the lock cylinder itself is very similar to the ones in the doors.

I do not have a COMPETENT locksmith in the area so I will make due.

did you try it both directions? it has two positions. if you really want it fixed you might try Z specialties (datsunstore.com) or email [email protected] . Mail it to him he can fix it or maybe get you one with a key. Again if you know your key code makes things much easier. little paper tag in the glove box with like X9999 or M9999 (it doesn't look very official handwritten). otherwise look at the hatch lock cylinder or driver door cylinder should be stamped there.

If you need a keyed gas cap.Just let me know...I have one with Key and cheap.

The car came with 2 keys. One was a valet key that would only open the door and ign. It was thicker i believe and would not fit the glove box nor gas.

The key I originally got was an old bent up Taylor key...I had to get a new one made because it was cracked.
