Door Lock Cylinders
My girlfriend and I just bought an Rx7 like a month ago. It runs and drives good, but I have a found a few things that i need to change. The top needs to be replaced.. but ultimately the door locks werent working. so i took the door panel apart and fixed the interior locks so they lock and unlock, but now I tried to stick the key in and turn the cylinder it doesnt turn, does anyone know how to fix these if possible, if not where do I buy a new one! Also the key works in the ignition and in the trunk but not either doors. So im puzzled on what to do. Please help me!

1991..state your CAR SERIES Dude..lots of Rx7's and different years here.Big thread at the top of the section states this.
If the cylinders were replaced then the key won't work work in them,Take the door cylinders out..pay particular attention to the passenger side lock,
take it to a locksmith and have them do the tumblers up to accept your key.
Another option is to buy a Whole USED set that the key works in ALL the Cylinders.
I bought a used set for 60 bucks..A real Deal,but they can be had a little more like 80-100 or so.
Not Bad considering what NEW would cost.
Don't ask to buy it in this section though(HINT!.Rules.) as you can only posts Ads in the Classifieds.

You could also try application of graphite grease, if you don't think those locks have been replaced with different tooling. Just make sure it's not white lithium, or wd-40, etc. If all else fails, take a key and rub it with pencil lead. If you get a spray bottle of the stuff, spray it on the key, insert, wiggle.

Sorry misterstyx I thought I had put the year 
I'm sorry! But anyways it didn't make sense that they would change the driver and passenger and not the trunk or ignition that was the reason I posted. Thanks for the replies I'm gonna email a locksmith near me and see how much they would charge to redo the tumblers

The door handles are a common failure point (like once in 15 years common) so they get replaced. If you're handy, you can re-key it yourself. Here's the directions I followed when I did mine. You can also let the locksmith do it.
Assuming that you have the lock out of the car and out of the handle...
1) remove the circlip that holds the arm onto the back of the lock and remove all of the attached pieces (metal arm, plastic arm, compression spring)
2) remove the round chrome cover at the other end by rotating it until the 2 indents align with the top and bottom of the lock and gently pry off
3) remove the trim plate, the door and it's spring taking care not to loose the pieces
4) insert any door key into the lock and while holding it so that the tumblers are at the top (you can see them through 2 small windows in the case) push on the back of the lock gently and the inner assembly will slide out (remember there is a small ball bearing and spring near the outside edge that acts to center the lock in the upright postion where you would remove the key, it's small and will be a bugger to replace if you loose it !) Also the tumblers and their springs could fall out if you are not carefull, so work over a towel and in an area if they do fall you have some chance of finding them! With the key in they won't fall out.
5) with the key still in place look at the top of the tumblers, also at the bottom, when set to the correct locations for the key in question they all will be flush, top and bottom. There are 7 of them and they can be interchanged with each other to match the key, normally you would only need to change those that are not flush, ie. one that it too high with one that is too low, repeating the process until they are correct and when the tumbler assembly is inserted into the cylinder with the key it turns freely.
6) lubricate the lock with the appropriate lubricant and reassemble.
I took all of the tumblers out and mixed them up, it took less than a couple of minutes to get them back in place to where the key I had choosen worked correctly.

I got 3 keys for one of my cars..so don't assume anything on a Previously owned car.
That is the luck of the draw,you run into The odd guy who is selling it just because he wants it gone..to you or anyone that will pay.
Or you get the guy who will tell you everything including what that Stain is on the seat!
