An intermittent ignition is one of the most frustrating problems a driver can have. The car starts fine for a week, then strands you in the Almansor Park lot for forty minutes, then works again like nothing happened. We get calls about this almost every day from drivers around Alhambra, so the Locksmith HQ Team put together answers to the questions we hear most often.
Why does my ignition work sometimes and not others?
Intermittent failure almost always points to one of three things: worn wafers inside the lock cylinder, a failing electrical ignition switch behind the cylinder, or a key that has been copied so many times the cuts are rounded off. Heat is usually the trigger you notice — a car that starts fine at 7 a.m. on Garfield Avenue but refuses to crank after sitting in the sun outside the Alhambra Place shopping center is showing classic signs of an electrical switch that expands when hot and loses contact.
The tricky part is that the problem fixes itself once things cool down, which makes people think it was a fluke. It isn’t. Intermittent ignitions get worse, never better.
How much does ignition repair cost in Alhambra?
For most vehicles we see around Alhambra, a lock cylinder replacement runs roughly $180 to $350 depending on the make and whether the new cylinder needs to be keyed to match your existing key. Full electrical ignition switch replacement on common sedans and SUVs usually falls between $220 and $450. European cars, anything with a push-to-start module, and older Fords with the PATS system can run higher because the parts cost more and programming is involved.
We give a firm quote on the phone before we drive out. No one likes the “we’ll see when we get there” routine, especially when you’re stuck on Fremont Avenue with groceries melting in the back seat.
Can I keep driving with an ignition that fails sometimes?
Honestly, no — and we tell people this even when it costs us a same-day job. A switch that’s failing intermittently can leave you stranded anywhere: the parking structure at Alhambra Renaissance Plaza, the on-ramp to the 10 at Atlantic, or worse, it can shut the engine off while you’re driving. Some switches also fail in a way that drains the battery overnight because the accessory circuit stays half-energized.
If your key has hesitated even twice, schedule the repair. Catching it on your driveway in Midwick or on Marengo is a service call. Catching it in the middle lane of Valley Boulevard is a tow plus a service call.
Will I need a new key after the ignition is fixed?
Not always. If we replace just the lock cylinder, we can usually key the new cylinder to match your existing key so nothing in your pocket changes. If your old key is worn down to the point that it’s part of the problem, we’ll cut a fresh one from the original code so it works smoothly in the new cylinder and your door locks.
For full electrical switch replacement on modern vehicles, the physical key doesn’t change at all — only the switch behind it. If you’re already thinking about a spare, this is the natural moment to handle at the same visit and save a second trip.
How long does the repair take, and do you come to me?
Yes, we come to you. Most jobs take 45 to 90 minutes start to finish, done in your driveway, an office parking lot, or wherever the car decided to quit. Lock cylinder swaps are on the shorter end. Electrical switch replacements that require disassembling part of the steering column take longer, especially on GM trucks and some Hondas where the airbag clockspring has to be respected.
Response time across Alhambra typically runs 20 to 40 minutes. South Alhambra near Cal State LA, the Emery Park area, and the neighborhoods off Atlantic and Valley are all within our normal coverage window.
Is this something a regular mechanic should handle, or a locksmith?
Either can do the work, but the economics are different. A dealership will almost always replace the entire cylinder and reprogram a key — that’s their playbook, and the bill reflects it. A general mechanic may not stock automotive lock parts and will mark up whatever they order. An automotive locksmith carries the cylinders, the switches, the key blanks, and the programming equipment in the van, which is why mobile ignition repair Alhambra calls usually come in faster and cheaper than the dealer route.
