The 2003 Toyota 4Runner should have a small access cover in the lower center portion of the rear door trim panel. Removing this cover will give you access to the rear door lock/latch assembly. It could be that the actuator portion of the assembly has failed in the lock position. You'll need to manipulate the mechanism on the assembly in order to get the latch to release and the door to open. If you need more room to do so, the assist pull strap can be removed followed by the rear door trim panel; this will be difficult in the closed position but possible with minimal damage to the trim panel. I would plan on having a new rear door lock/latch assembly ready for installation as they are rarely fixed via lubrication. Rear gate lock/latch assembly replacement is very similar that of a trunk on a sedan which you can read about here: https://www.yourmechanic.com/article/how-to-replace-a-trunk-lock-actuator-by-michael-france

Sounds like the latch closed on you. Make sure the door is unlocked, then pull up on the outer door handle, take a small screw driver to reach into the latch to pop it open. the door should then close normally.

You can look at the front doors latch to see what it is supposed to look like first, it may help.

Other wise you will have to replace the door latch, witch is a fairly common problem on those. And not much fun to do.

Hi chance are the mechanism inside door jamming. Short of forcing off the inner panel in order to clean lubricate etc I find the best way to get this open is to get someone to keep activating your central locking open and shut while you simply keep trying the door handle at the same time and this can some times just catch the latch in just the right position to get the door open ( you dont need to forcefully be pulling on the handle as the latch will either simply click over on the fine spring latch mechanism or not force is not going to help).
Once and if you manage to get door open take off the inner door card panel and oil lubricate mechanism. rather than then shut door simply use a screw driver on latch to test and worth then working back and forth. If still jamming replace latch.

child lock on should still let you open and close from the out side .
Make sure the door is unlocked and check to make sure the latch did not relatch it sef before shutting the door if it did take a screw driver and manualy open it by pulling the outer door handle and popping the latch back open with the screw driver. if this is not the case then most of theese problems can be fixed whith a can of WD-40 and just working the latch back and forth

your gonna have to remove the inner dor panel and replace the latch lock assembly

Check all the switches at the door jambs. Switches can get pushed backward out of their mount or can even go bad or have bad wire connection.

You need your door lock actuator's replaced because they are sticking.
