Okay, spoilers:

After you spare Asgore, you should get dialogue from Flowey telling you to turn back and head to Undyne, making you cross the bridge from the resort to the Core. You'll receive Undyne's call at the begining of the bridge. After receiving the call, head back to Alphys' lab and you'll continue from there.

For Sans' lab is different, I believe, but when you reach him in the corrider, save then talk to Sans. After that, DON'T SAVE AGAIN and reload your game. Do this 4 times until you give him the 2nd passcode and he'll give you a key. After that you can save again and head back to Snowdin behind Sans' and Papyrus' house.

I've done True Pacifist as my first run, and was successful. However, I'm currently on my 2nd Pacifist run (mainly to get the happy ending with the characters on the full screen, I hope) and I'm going to attempt to do the San's lab thing on my own, but I'm using information I've seen before and was successful.

Good luck and sorry if you didn't find this useful.
