Late May in Altadena means the jacarandas are dropping purple all over Lake Avenue, the Farmers Market on Loma Alta is back in full swing, and afternoon temperatures are starting to climb past 90. It also means we get a lot more calls about cars that won’t start — specifically the kind where the key turns, the dash lights up, and then… nothing. No crank, no click, just silence or a sad whir.
If that sounds like your morning, you’re not alone. Summer is hard on ignition switches, and we’ve been busy across Janes Village, the Meadows, and up toward the Country Club area dealing with exactly this issue.
What’s Actually Happening When the Key Turns But the Engine Won’t Start
People assume a no-start means a dead battery. Sometimes it does. But when your key physically rotates through all the positions — accessory, on, start — and the dashboard wakes up normally, the battery is usually fine. The problem is downstream.
The ignition switch isn’t the metal cylinder your key slides into. That part is the lock cylinder. The actual switch sits behind it, and it’s an electrical component with tiny copper contacts that wear out, corrode, or melt. When those contacts fail, turning the key all the way to “start” sends no signal to the starter motor. The engine never gets the command to crank.
Why Summer Makes It Worse
Heat is the enemy of those copper contacts. A car parked on Mariposa Street in full sun can hit interior temperatures north of 140°F, and the steering column traps heat even longer. Contacts that were “almost failing” all winter finally give up in May or June. We see a noticeable spike in ignition repair Altadena calls between Memorial Day and Labor Day every year, and 2026 is shaping up the same way.
Older Hondas, Chryslers, and GM vehicles from the early 2000s are especially prone to this. Ford trucks with the PATS system have their own quirks. Hybrids and newer push-to-start vehicles fail differently — usually a worn-out brake position switch or a dying key fob battery rather than the ignition itself.
Before You Call Anyone
A few quick checks can save you a tow bill:
- Jiggle the steering wheel while turning the key. If the wheel is locked against the steering column, the ignition won’t rotate fully. This is the single most common “my car won’t start” issue we drive out to.
- Try the spare key. If your daily key is worn down, the wafers inside the cylinder may not align well enough to complete the circuit. A fresh-cut spare often starts the car right up.
- Put the shifter firmly in Park, then try Neutral. A failing neutral safety switch mimics ignition problems.
- Check the dash for a flashing security light. A solid or flashing key icon means the immobilizer isn’t recognizing your transponder — that’s a different fix entirely, closer to than an ignition repair.
When It’s Definitely the Ignition Switch
If the key turns smoothly through every position, the dash lights up, but the starter never engages — and you’ve ruled out the steering lock and shifter — it’s almost certainly the switch. Sometimes you can tap the key gently while turned to “start” and the engine will catch. That’s diagnostic: those worn contacts are making intermittent connection.
Driving around like that is rolling the dice. The next failure usually leaves you stranded somewhere inconvenient — the parking lot at Webster’s, halfway up the grade to Eaton Canyon, or worst case, blocking the gate at JPL on a Monday morning.
Seasonal Tips for Altadena Drivers
A few things that genuinely help if you want to push your ignition switch through another summer:
- Park in shade when you can. The municipal lot off Mariposa, the spots under the sycamores along Mendocino, and most of the residential streets in the Meadows offer real cover.
- Lighten your keychain. The weight of fifteen keys, two bottle openers, and a Disneyland lanyard pulling down on your ignition every time you drive is a real cause of premature switch wear. We’re not making this up.
- Don’t crank repeatedly. If it doesn’t start in two tries, stop. You’re burning out the starter solenoid on top of whatever the original problem was.
- If you’re planning a summer road trip — Mammoth, Big Sur, the Eastern Sierra — get the switch looked at before you go. A failure in Lone Pine costs ten times what it costs in Altadena.
