It's actually pretty easy
Pull a door handle from a wrecking yard. The lock mechanism is held in place by a wrap around spring type retainer. Just pry it back from the slots and it slides right out.
Take the replacement to a locksmith with your old lock and spare key. Leave it for a hour or so, and you're good to go. Slide the replacement in, pry the wrap around spring retainer back in place, drop the door handle back in with the two 10MM nuts.
Done.

get another lock from the junkyard and take it to a locksmith. Im pretty sure they can modify it so your key works with it. Taking off the lock is simple. Take off your door panel and If I remember correctly theres two nuts holding the handle in place. You can probably take the lock off without removing the handle. Not too sure though.

After some *** stuck a screw driver in my locks trying to get in? (I can slimjim the 2nd gens w/ a folded piece of paper in 30 seconds...) and actually broke the door handle and one of my tumblers off the door handle casting I had to take my tumblers apart. CAUTION-use saftey glasses, they have very small parts and springs-my Uncle lost his eye to a Peugot tumbler. I took mine apart and filed the little pieces back flat and straightened the bent springs and even had to rivit the handle back together inside and make a set screw to hold the tumbler in the handle (my Grandpa was a clock/watch repairman-guess its in the blood). Worked great after I was done-smoother than before the damn vandals violated it. "You can do it..."

It may be worth the effort to dismantle the lock and check the tumblers,(per Blue TII).They often suffer from lack of lubrication and/or dirt and can easily be cleaned up.The tumblers are numbered so be sure to keep track of the position and number.If you need replacement tumblers grab a bunch of Mazda locks from the wreckers(323,626 etc are all the same.

Door locks...
The lock assemblies are the same (driver and pass) except for the stamped steel mounting bracket and the arm attached to the back of the cylinder.
BUT, I just went through this with the drivers door as well and I would recommend for all of the work to remove 2 interior door panels and 2 sets of connecting rods and 2 door handle assembles, that it would be WAY faster and better to just buy another lock assembly and re-key it to the keys that you have.
The driver's door gets the most use and by moving the passenger lock over all your doing is buying a little time before it goes, and leaving yourself with a lock on than passenger side that may not be able to be used as a backup!
I purchased mine from the dealer for $56Cdn (probably way cheaper down south) and re-keyed it my self in just a few minutes.
BTW the part number for the 'illuminated' drivers side lock on a '91 is: FB01-76-220B
Mazda door lock re-key, a piece of cake...
Assuming that you have the lock out of the car and out of the handle...
1) remove the cir-clip 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 position 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 careful, 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 chosen worked correctly.
