Maintenance/Repairs

I’m having a frustrating start-up issue with my 2005 Honda Accord LX (2.4 L, automatic). Here’s what’s happening:
• No Crank / No Noise
– Turning the key does absolutely nothing—no click, no cranking, just silence.
• Key Gets Stuck
– The ignition key often won’t release; I have to jiggle it or disconnect the battery to pull it out.
• Green “Security” Key Light Flashing
– The dash security/immobilizer icon blinks continuously instead of going out.
• Green “D” Gear Indicator Flashing
– The “D” on the instrument cluster flashes green, even when parked.
• Shift-Lock Bypass
– I can move the shifter out of Park without pressing the brake pedal.
• What I’ve Tried
1. Key Reprogramming: Had all keys re-programmed—no change.
2. Battery & Connections: Battery reads ~12.6 V at rest; terminals are clean and tight.
3. Brake Lights: Function normally when pedal is pressed.
4. OBD2 Scan: No stored fault codes.

I suspect the STOP-lamp fuse, brake-light switch, shift-lock solenoid, neutral‐safety (range) switch or immobilizer loop might be at fault—but I’m not sure where to begin.
