Topology:Left-right
Strokes:12
Writing Balance Rule: The left radical (钅) is narrower and compressed, leaving ample horizontal breathing room for the right phonetic component (琐 / previously 𤇾 simplified to 𨥙/贝 side).
Simplification Logic: The traditional form 鎖 uses 釒 on the left and ㊌ (suǒ) on the right. In simplified Chinese, the metal radical is standardized to 钅, and the right side is simplified to 贝 for modern writing ease.

Sandhi: When followed by another 3rd tone syllable, suǒ changes to a 2nd tone (35) due to tone sandhi rules.
