My rear hatchback lock on my '94 RX-7 is apparently a different lock than my doors and ignition. I've only had the car a few months and discovered this shortly after I bought it, but it just hasn't been that big of a deal. At any rate, it's obviously not a terribly big deal, but I would like to be able to open the hatchback from the outside. As it is now, I have to pull the lever everytime.

Questions...

1. Is it possible to just have the rear hatchback lock re-keyed to my other keys and locks?
2. If so, how much might that run?
3. If so, can anyone recommend someone in Houston that could do that?
4. If not, how much would a full lock set generally run?

Thanks for the help.
