Car Won't Start, No Click — Causes and Next Steps

What's happening

If the dashboard lights up but turning the key produces nothing — no click, no crank — the high-current path to the starter isn't being commanded. Usually it's the low-current control side: ignition switch, neutral safety switch (auto trans must be in P or N), clutch safety switch (manual), or the immobilizer rejecting your key.

You might also notice

• Dashboard lights normal
• Sometimes works after wiggling the shifter
• Security indicator blinking
• Sometimes works on the second or third try

Likely causes (most common first)

1. Completely dead battery (try jumping)
2. Failed neutral safety / range sensor — try Neutral instead of Park
3. Failed clutch safety switch (manual transmission)
4. Immobilizer fault (usually a low key fob battery or worn ignition switch)
5. Failed ignition switch
6. Blown starter relay

What to check first

1. Try shifting to Neutral, then crank — if it starts, you found a range sensor or shifter cable issue
2. Manual: press the clutch all the way to the floor; some cars have a strict cutoff switch
3. Replace the key fob's coin battery if the dash 'no key detected' light appears
4. Listen for the fuel pump prime when you turn the key to RUN — if you hear it, the immobilizer is happy and the issue is the starter circuit
