How do you open a 1990 Mazda miata trunk without a key?

Answer 1

If you have to remove the rear seats No such thing as rear seats in a Miata. I own a 90 Miata as well and locked my keys in the trunk once - NIGHTMARE! under the trunk there are two small "punch-holes. it's not easy, but if you punch the one on the passenger side out, then someone with slender hands can reach up into the trunk and pull on the release wire that runs from the lock to the latch. (Hint: I had to cut out some carpeting after punching out the hole in the bottom of the trunk - I don't know if there is a better or easier way, but that's what worked for me.)
