The doors unlocked then locked again straight away by them selfs, then locked and unlocked randomly while driving for the day and at the end of the day nothing works, all the fuses are fine which wires need checking for power in the drivers door, is it the positive that switches the actuator or the earth
Here is a central locking diagram - but be warned - they are not all the same.as this. Depending on the model, Discos mostly have the control units as integral components of the front door actuators. The back door units are just slaves
Remove the side panel under the foot-well so you can get at the wiring loom. also remove the front door trims to get at the actuators, then test the wires going through the doors with an ohmmeter to ensure continuity - it would not be the first time a broken wire caused all of the system to fail.
In other words, do the simple things first

there is several components but it sounds to me like your drivers door latch has failed as this is main unit to send signal to other doors

Please dont worry yourself so much the security locks needs to be reprogrammed to enable it work effectively. Same happens to other vehicles as well.
Consult Hyundai garage close to you or if you have it in your manual.
Good luck.

Does it open from the outside once you have manually opened it from the inside.

This can be caused by the actuators in the lock mechanism
failing usually causing the door to remain locked. The boor door can
also fail this way, though sometimes the catch sticks (pry off the LR
badge, squirt with WD40 and work it a few times to fix that).
Replacement requires the
whole lock unit to be replaced at a cost of roughly £60 a lock, and a
hours work. Helps if you have small hands. It does require a complete
strip down of the door, and will need the lock unit, trim panel clips,
and a trim removal tool. Clips are a few quid, the tool's usually around
a tenner.
For the rear door, this is slightly easier due to the lack of moveable glass, so you just need to get the rear panel off including sub and open it.
Try clicking unlock on your fob while pulling the latch inside. This may pop it open at the crucial point. If you put the child lock on, you're stuffed! I saw one at a breakers yard where they had to use a disc cutter to get the door open.

No, likely to be caused by the actuators in the lock mechanism failing usually causing the door to remain locked. The boor door can also fail this way, as do the front side doors. Replacement requires the whole lock unit to be replaced at a cost of roughly £60 a lock, and a hours work. Helps if you have small hands. Requires a full strip down of the door and you will need the lock unit, trim clips (a few quid) and a trim removal tool (tenner). You can bodge with a flat head screwdriver, but the tool does help prevent damage to the clips & trim panel.
