About this part

This assembly combines the ignition lock cylinder, where the key goes, with the ignition switch that powers the car's circuits. Worn cylinders make the key stick or refuse to turn, while a worn switch can cause stalling, no-crank faults or dash lights that flicker. The US-555 replaces both at once and comes with its mounting bracket. A new lock cylinder means a new key, so expect to carry a separate ignition key unless it is rekeyed.

Fitment notes

Rows list the US-555 for the 2003 Honda Civic DX and the 2004-2005 Honda Civic. Civics with an immobilizer key need the key chip handled correctly, so confirm your system. Compare your current assembly, then check the fitment table or send your VIN.
