Question about 2002 Toyota 4Runner
Key fob unlocks doors fine/beep sounds if door is open and you press lock/with key in ignition you can feel actuator trying to lock when you depress switch(only with key in ignition). Dorr switch wll only unlock.
First of all, check ACC fuse in the driver side junction box. The central controller for power door locks is the body ECU. From your description it may be working only partially. Can the doors be locked using a key? If so, this would indicate the actual locking mechanism is OK. Do the front door lock control switches lock the doors?

You need to replace the electric door lock solenoid.The electrical part of the solenoid may be compromised and is not letting the solenoid arm retract or extend to lock/unlock your door.

If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.

if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
that go to door locks
