The driver's door and trunk locks on my 2002 Subaru Legacy are jamming, to the point where I can not open my trunk. The driver's door is on its way to meet the same fate! Any easy fix for this?

no year car told. the now lost free users guide is by year.
made 1994 to present (even 1989 as legacy outback)
no country told at all
sorry cars not the same world wide.

open glove box, read the users guide? oops locked too>?
most cars sold in USA , called wagons
opening the rear gate hatch by accident driving
kids fall the ground, or cargo hits cars behind you. (so is illegall that feature)
and is never called a truck ever, in a wagon
only on sedans. a hatch or 5th door it is named.
In Europe then even call them 5 door cars.
so I am confused.
so all keys lost to the car. and can not drive it
nor open any side doors
and rear hatch is locked and valuables in cargo area to fetch, right?
I say call a locksmith
and pick the lock.
the door lock(mechanism) in the hatch internal, is accessed from the inside of the hatch open.so no why to attack it that way.

call a locksmith,

It says the tachometer wire is Yellow/Green, you do not have that listed. You will find it in the list below, it is highlighted..

better to adjust the trunk lock mechanism by trained person.

Replacing the drivers door switch most often takes care of this problem. Due to the cost of the part have a dealer confirm this.

you gotta check the door switches, one of them is faulty,

bad sensor button maybe

The #3 fuse does service both windows and door locks and #2 services a control module that affects door locks. Inspect them closely since the fuse element can crack when blowing and this is much harder to see. Pull a least #3 and plug it back in in case the contact blades have stopped comunicating with the mating connector.

To troubleshoot this effectively, you really need a cheap multimeter and the Haynes service manual for your car, #89101.
The manual has very good electrical diagrams in section 12 so you can logically trace the problem. They are available at most every auto parts chain store and cost ~ $20-25 US.

Legacy, right? Can you tilt the backseats' backrests forward? like when you want to transport something big in the trunk... I suppose the sedan has this similarly to the station wagon. 
Use a pocket torch to look for the lock body from inside and there should be a small button or better a lever that you have no clue what it is there for, right? try to push it or pull it from ech side untill it opens. 
It is actually there to prevent transporting people in the trunk against their will(unlike the movies, where it is possible).

Feel free to send any feedback

Check for a rusty handle. If you push the handle forward then try the power unlock then open the door with handle. I have been finding that the handle becomes rusty and does not return all the way when released. Therefore not allowing the locks to disengage. Hope this helps.

If it's mega cold in your area, it could be ice. We've had several things not open lately. All due to moisture/condensation freezing.
Just a tho't.
