Buyer's checklist
What to check before buying a used ignition switch
- Determine if the unit includes the mechanical lock cylinder with matching keys, or if it is purely the electrical ignition switch contact block.
- Match key transponder chip frequency (Passlock, PATS, or RFID) and verify if anti-theft relearn or key programming tools will be required.
- Inspect wire harness pigtail connectors for burnt plastic or loose female spade terminals caused by ignition circuit overload.
- Verify key cylinder positions (Accessory, Off, Run, Start) turn smoothly without sticking, binding, or requiring key jiggling.
