Key Points
1交換( means replacing the broken lock here
- 交換
( often means “exchange”, but here it means taking out the broken lock and putting in a new one. - The missing object is clear from the scene, so Yousuke does not say what he plans to replace.
2こりゃ is a casual form of これは
- こりゃ points to the situation Yousuke has just dealt with, much like “this” or “the way things are”.
- In the translation, “Looks like” captures his reaction to the state of the lock.
3さっさと交換( した方( がいい expresses his judgment
- 〜た方
( がいい presents an action as the better choice. Here Yousuke decides that replacing the lock is better than leaving it as it is. - さっさと adds urgency. He thinks it should be done without delay.
- Final な makes this sound like a thought to himself rather than advice directed at someone else.
4売( ってるトコ expands to 売( っているところ
- 売
( ってる drops the い from 売( っている in casual speech. Here it describes a place that sells replacement locks. - トコ is a clipped form of ところ, “place”.
- あったっけ shows Yousuke searching his memory, and なぁ lets the question trail off as he thinks.
