To prevent thieves from slashing your top and easily gaining access to the trunk via the remote trunk release in the cneter console, you can modify the trunk lock to temporarily disable the remote trunk release.

The Miata trunk can be opened remotely with a lever inside the center console. To temporarily disable this remote trunk opener, a simple modification has to be made to the tumbler of the trunk lock. So I took it apart:



I used my trusty Dremel to file off a little notch on the tumbler and now I can disable the remote release by turning the key counter-clockwise. That way, you either have to brake open the trunk or have a key to get in.
