Question about 1998 Subaru Legacy
My passenger door won't unlock on my 2002 Subaru Forester. When I press the power unlock button the lever flips to the open position and then immediately returns to the locked position. Even if you try holding it in the unlocked position it will not allow you to open the door.
I want to fix it, of course, but I first need to get the door open so I can take the panel off.

Have a '03 2.5 Premium Outback and same thing happened. Easy fix this one, it's a flat battery....inside the black case on the end of the key. go to your local Tandy or similar store and buy a CR 1620 battery. Then with a very fine jewelers phillips head screwdriver undo the small black screw at the base of the chrome key shaft. Then carefully and gently pry open the two halves of the black plastic part of the key. The round silver disc inside is the battery. Pry it out and put it in your pocket, (so you don't mix it up with the new one!!!!) and fit the new battery with the numbers etched in the battery facing down. Put the two halves back together, fit the screw back in (most important), then point it at your car. Wallah!
A new battery shouldnt cost anymare than a few bucks, and do both key remote's at the same time, regardless of use, because the batteries are the same age.

If it takes that much force to manually open the doors, and it's on the doors that are less used, then I'd bet it's a set of door locks and actuators in need of lubrication.
Electric door lock actuators can easily be stopped or slowed down by resistance in the mechanism. This can be caused by corrosion, water getting into the door, and just old age and lack of use. I'd take the door panels off and take a peek.
On the Legacy the panels pop off fairly easily. You'll need to pry them off carefully with a flat screwdriver. You'll feel where the fasteners are, where the panels are resisting coming off, and prise the panel gently and firmly at these points and they'll pop out. Once out you'll see the lock mechanism.
Moving it by hand will tell if it's corroded or bound up. Apply some white litium grease to the mechanism, making sure to squirt/work it in, and then work the door handle/mechanism to get the lube into the linkage and actuators. Check the electrical contacts for corrosion while there and spray with WD-40 to protect them. This should free up the door mechanism and the actuators should then be able to do their job.
If after the above steps the electric actuators still don't work, use a voltmeter or circuit tester to check for 12V at the actuator when the door button is pressed. If you don't see any power, recheck that fuse and then the wiring back to the door harness. It's unlikely that this is the cause as its unlikely that you'd get only 3 out of 4 bad, but you never know in these old cars.
Hope this helps.

The problem I have found many times is the Handle on outside not returning all the way. That makes the lock not release. Check to make sure you push the handle all the way back to the closed position. I have to spray lube on the edges of the hndle every couple months to free it for my wife. Good Luck and have a great day.

Same thing happened with mine. It turned out that the
power door lock motor went out. Since the handle or the switch can unlock the
driver's door, both of these mechanisms are connected. When the door lock motor
goes out it freezes in whatever position, it was last engaged.
