Why Your Key Turns But the Car Won’t Start in Phoenix, AZ
You sit in your car, turn the key… and nothing. No crank, no dashboard lights—just silence. This frustrating situation happens to drivers all across Phoenix and can leave you stranded without warning.
At Affordable Security Locksmith And Alarm, we help diagnose ignition and key issues quickly on-site. If your key turns but the car won’t start, visit our mobile automotive locksmith page for Phoenix to get help fast—whether you’re in a driveway, parking lot, or on the roadside.
Here’s a breakdown of why your key might be turning without starting the vehicle—and what a mobile locksmith can do to fix it.
Common Reasons Your Car Doesn’t Start When the Key Turns
1. Faulty Ignition Cylinder
Over time, your ignition cylinder can wear down. When this happens, the key may turn, but it doesn’t engage the ignition switch properly.
Symptoms:
- No dashboard lights
- No crank or engine noise
- Key turns loosely or feels off
Fix: We can repair or replace the ignition cylinder and rekey it to your existing key.
2. Worn-Out Key
A key that’s been used for years may no longer align properly with the tumblers inside your ignition, even if it turns.
Symptoms:
- Key works in door but not in ignition
- You have to wiggle or hold the key to get a response
- Starts sometimes, but not consistently
Fix: We can cut a new key from code instead of copying the worn one, restoring clean alignment.
3. Transponder Chip Failure
Modern keys have a chip inside that talks to your car’s computer. If the chip is damaged or not recognized, the engine won’t start—even if the key turns.
Symptoms:
- “Key Not Detected” on dash
- Car won’t crank
- Remote unlock works, but engine doesn’t respond
Fix: We’ll test the chip, and if needed, program a new key or fob on-site.
4. Ignition Switch Malfunction
Even if the key and cylinder are fine, the switch behind the ignition may be faulty and fail to send power to your starter, fuel system, or dash.
Symptoms:
- No electrical power
- Dash lights flicker or don’t show
- Turning the key has no resistance
Fix: Our locksmiths can replace the ignition switch and ensure everything is properly wired.
5. Dead Car Battery
Sometimes the issue isn’t the key at all—it’s a completely drained battery.
Symptoms:
- No lights, sounds, or fob response
- Clicking noise when trying to start
- Dome lights and radio are dead
Fix: We’ll test your battery and jump it if needed, then check if your key system needs reprogramming after power is restored.
