Get the key turning and power flowing through your ignition system again with the Standard Ignition Ignition Lock Cylinder and Switch (MPN US-662). It installs as a direct-fit replacement for the 1988-1989 Honda Civic and 1988-1989 Honda CRX.

This unit pairs the mechanical lock cylinder — the keyed tumbler mechanism your key inserts into and rotates — with the ignition switch that routes battery power through the OFF, ACC, ON, and START positions as the key is turned.

  • Combined assembly: integrates the lock cylinder and the electrical ignition switch in one serviceable part.
  • Key-controlled function: turning the key operates the switch to power accessories, energize the run circuit, and engage the starter.
  • Signs it may need replacing: a key that's hard to insert or turn, sticks in the cylinder, or an engine that won't crank or loses power in certain key positions. If a failed lock cylinder or ignition switch is the cause, this replaces it — diagnose the root cause before ordering.
