jiàn

key (on a piano or computer keyboard)

button (on a mouse or other device); chemical bond; linchpin

metal (钅) + sound jiàn (建) = the metal key or bond

The metal radical grounds the meaning in something physical — a metal piece that locks, connects, or activates. 建 gives the sound jiàn and does not carry the meaning here.
