Secrets. Caches, keys and hidden objects. Need help!

1. Where to use the key with the heart? I'm talking about the key to "Wishless resting place puzzle" (The answer is found: The key is used in a cave under the city )

2. "Barons Map" where is the place depicted on this map? Answer: On the way to the dragon , two grape bushes grow on the right side.

3. There's a door in the crypt on the ground floor that I can't find my way to. This door is located in the lower right corner of the location. Does anyone know how to get there?
(The answer is found: The entrance is on the street. Over a village that was in a fog. There you need to find a dry tree and cut it down. You need a rope to descend. There will be gold. (Terrible game design. Not worth the time spent.) )

4. A locked door in the Thieves' tower. Ground floor. A key is required. There are two chests behind the door.

Don't know where exactly but I saw discussion about an npc who sells 3 unique keys. The Thieve's tower spot you mention is one of them.

2, is Blackbarrow near a road where two trees stand out from the rest by the looks of it as I just got it then.

Found it, the South West path from Sild between two grape vines.

Just answering this for other people. It's a "Jack Key" to get into the Tower room. I bought it I believe.

There's a thief quest. That guy stole the artifacts from the church storage room. He will show up on a three prong northeast of Aventurine at some point during the day. You can either deliver the stuff or return the artifacts to the church and go there to kill him then you get the key.

Could you please tell me how I make it to trigger then? I bought the items for 20000 gold on the thieves tower before activating the quest. Will I be able to get the key or I screwed myself?
