Ignition Repair Cost in Plano (2026)

Almost every ignition quote people receive over the phone is wrong, and not because anyone is being dishonest. It is wrong because "my ignition is bad" describes at least five completely different failures with completely different price tags, and nobody can tell them apart from a description. This page prices ignition work the way a technician actually diagnoses it: by failure type. For mobile ignition service in Plano, call or text (945) 307-3827.

Quick Answer

As of August 2026, ignition repair in Plano runs roughly $85 to $450 depending on which failure you have. Pulling a broken key out of a cylinder is about $85 to $180. Rebuilding a worn cylinder to your existing key is about $170 to $340. Replacing the cylinder with a new key cut is about $250 to $450. An electrical ignition switch is about $200 to $400.

Ignition Repair Pricing in Plano by Failure Type

Repair	Typical Plano range (Aug 2026)	On-site time	What it fixes
Diagnosis, applied to the repair if you proceed	$75 - $140	20 - 35 min	Identifies which failure you actually have
Broken key extraction from the cylinder	$85 - $180	20 - 40 min	Key snapped off, cylinder otherwise fine
Worn lock cylinder rebuild, keyed to your existing key	$170 - $340	45 - 90 min	Sloppy, gritty, sticking cylinder
Lock cylinder replacement with a new key cut	$250 - $450	60 - 110 min	Cylinder seized or too worn to rebuild
Electrical ignition switch replacement	$200 - $400	50 - 100 min	No crank, no accessory power, intermittent stalling
Immobilizer antenna or transceiver ring replacement	$180 - $350	45 - 90 min	Key turns, security light stays on, no start

Push-button-start vehicles are deliberately absent from that table. Their failures live in modules and switches rather than in a lock cylinder, and quoting one without seeing it would be a guess. Those start with the diagnosis line and get a firm number once the fault is identified.

The Five Failures People Call "A Bad Ignition"

1. The key is hard to turn, or only turns when you jiggle it

This is mechanical wear, and it is the most common ignition call in Plano by a wide margin. Every time you turn the key, brass wafers inside the cylinder slide against a blade that is itself wearing down. Ten or fifteen years of that and the two no longer line up cleanly.

The tell is gradual onset. It got a little worse each month, you learned a trick that makes it work, and one day the trick stopped working. If the car is a decade old and the key has been in daily use that whole time, this is almost certainly what you have.

Cost depends on whether the cylinder can be rebuilt. A rebuild replaces the worn wafers and keys the cylinder back to the key you already carry, which is the cheaper outcome and keeps one key working everything. If the cylinder housing is damaged or seized, replacement is the honest answer, and that comes with a new cut key. We cover the wear pattern in detail on our page about a worn ignition key that will not turn.

One thing worth checking before you pay anybody: a steering wheel under load will lock the cylinder and refuse to let the key turn. Rock the wheel gently left and right while turning the key. If it frees up, your ignition is fine and you have parked with the wheels turned against a curb, which happens constantly on the sloped driveways in older Plano neighborhoods.

2. The key broke off in the ignition

A blade snaps because it was already worn thin, usually right at the shoulder. Extraction itself is often quick, and the price reflects that. What matters is what comes next: the key broke for a reason, and the reason was normally either a fatigued key or a cylinder tight enough to require force. Extracting the fragment and handing you the other half of a failing key solves the afternoon, not the problem.

We quote extraction and cutting a fresh key separately so you can see which is which, and we look at the cylinder while we are in there. The full walk-through of that job is on our broken car key extraction page.

3. Nothing happens when you turn the key, or the dash flickers

Now you are on the electrical side. Behind the mechanical lock cylinder sits an electrical switch that actually sends power to the accessories, the run circuit and the starter. When that switch wears out, the symptoms are electrical rather than mechanical: the key turns normally but nothing comes on, or the dash lights flicker and drop out while you drive, or the car stalls over a bump.

This one is worth taking seriously and worth fixing promptly, because a switch that drops the run circuit at speed is a safety problem rather than an inconvenience. The symptom set is described on our page about an ignition feeling loose while the dash flickers.

Mechanical and electrical failures can coexist on the same car, and on high-mileage vehicles they frequently do. That is one reason a phone quote is unreliable and a diagnosis is not wasted money.

4. The key turns, the engine cranks, and the car will not start

Nothing here is a lock problem at all. The cylinder did its job and the starter did its job. What failed is the security handshake: the car did not recognize the key as authorized, so it cut fuel or spark.

The usual culprit is the transceiver ring, the antenna coil that sits around the ignition lock and reads the chip in your key head. It sits in a hot, vibrating spot for a decade or more and eventually the winding fails. From the driver's seat, a failed antenna ring is indistinguishable from a failed key, which is why people replace keys that were never the problem.

The signature is a security or immobilizer light that stays lit or flashes rather than going out after a couple of seconds. If your dash is doing that, start on our page about the immobilizer light staying on with no start before you buy anything.

5. The shifter will not release, or the key will not come out

Interlocks. A cable or solenoid ties the ignition, the brake pedal and the transmission shifter together so the car cannot be left running in gear or shut off out of park. When the interlock fails, the ignition takes the blame, because the ignition is where you notice it.

These repairs vary far too much between vehicles for an honest range. They also occasionally point past the ignition entirely into a control module that has lost its calibration, which is a programming job rather than a mechanical one - the kind of work described on our pages about PCM replacement and VIN programming and transmission control module programming, since a shifter that will not release is as often a module reporting problem as a mechanical one. Diagnosis first, quote second.

What Moves the Number Inside Each Range

Where the lock cylinder sits. A column-mounted cylinder behind a two-piece plastic shroud is a fast job. A dash-mounted cylinder buried behind trim, or a column that requires an airbag-adjacent disassembly, doubles the labor before anyone touches the lock.

Whether the car has to keep its original key. Rebuilding a cylinder to your existing key costs a little more in labor than fitting a new one with a new key, and it saves you from carrying two different keys for one car. On a vehicle where the doors and trunk still work on the original key, it is usually worth it.

Whether the immobilizer is involved. If the repair introduces a new key, that key has to be registered to the vehicle before the car will start. On older vehicles that is minutes. On newer ones it is a procedure with its own duration, and the ignition quote has to include it.

Parts availability. Common domestic and Japanese cylinders ride in the van. Less common vehicles occasionally need a part ordered, which changes the day of the repair but not the price.

When and where. After-hours work carries a surcharge, as it does with every locksmith in DFW. A car parked safely overnight in a driveway near Preston Road costs less to fix at nine in the morning than at midnight.

Repair or Replace: How We Decide

The decision is not sentimental and it is not about upselling. It comes down to three questions.

Can the cylinder be rebuilt to spec? If the housing is intact and only the wafers are worn, a rebuild returns it to correct operation and keeps your existing key working. If the housing is cracked, the cam is damaged, or the cylinder has seized hard enough to have been forced, a rebuild is a temporary answer to a permanent problem.

Is the electrical switch healthy? Replacing a lock cylinder on a car whose real fault is the electrical switch behind it produces an unhappy customer and a second visit. We check both before quoting either.

Is the key itself worn out? A tired key wears a fresh cylinder fast. If your key blade is visibly rounded, cutting a new key to factory specification at the same time protects the repair you just paid for. This is the single most common thing people decline and then regret.

Model-Specific Ignition Guides

Ignition behavior varies enough between platforms to be worth its own page in several cases, and we have written up the vehicles we see most in Plano:

• Toyota Corolla and Prius ignition repair
• Ford Focus and Fiesta ignition repair
• GMC Sierra and Yukon ignition repair
• Jeep Wrangler JL and JK ignition repair
• Chevrolet Equinox and Blazer ignition repair
• Subaru Ascent and Legacy ignition repair
• Mazda6 and CX-30 ignition repair
• Dodge Charger and Challenger ignition repair

If the cylinder turns out to need full replacement rather than a rebuild, the process and what it includes are set out on our ignition replacement service page.

Mobile Ignition Work Versus a Shop

Nearly all of this is driveway work. The tools are portable, the parts are compact, and the car does not need a lift. That matters more than usual with an ignition, because a car with a failed ignition frequently cannot be driven anywhere, and a tow is a real expense that a mobile repair simply avoids.

The exceptions are honest ones. A vehicle needing steering column disassembly around airbag components, or a fault that has followed the wiring back into the body harness, belongs in a shop. When a job crosses that line we say so on-site rather than starting something that should not finish in a parking lot.

Cheaper Than Any Ignition Repair

Two habits prevent most of the calls on this page, and both cost almost nothing.

Take the weight off your keyring. A ring loaded with keys, a bottle opener and a carabiner hangs off the cylinder every minute the car is running, and that constant side load is what wears the wafers out early. Car key, house key, done.

Replace a visibly worn key before it takes the cylinder with it. A key with a rounded blade is sandpaper. Cutting a fresh one to factory specification is inexpensive compared with everything in the table above, and it is the highest-return maintenance item in this entire trade.

What an Honest Ignition Quote Should Include

Ignition work is one of the easier places in this trade for a quote to grow after the technician arrives, so it is worth knowing what a complete number looks like before you agree to anything. Four questions settle it.

Does the price include the key? A cylinder replacement produces a new cut key by necessity. A quote that covers only the cylinder and bills the key separately is not wrong, but you should know that before the van rolls, not after.

Does it include programming? If the repair introduces a new key on a vehicle with an immobilizer, that key has to be registered before the car starts. Cutting without registering leaves you with a key that opens the doors and starts nothing.

Is the diagnosis credited against the repair? Ours is. Some are not. It is a fair question and the answer should be immediate.

What is the after-hours or trip charge? Every mobile locksmith has one in some form. A shop that says there is none is either absorbing it into the repair price or has not told you yet.

A quote that answers all four in a single phone call is usually the quote that holds. One that answers "it depends" to all four is a dispatch service that intends to price the job in your driveway with your car already apart.

A Recent Plano Example

A customer near Independence Parkway called about a key that had been getting harder to turn for months and had finally stopped turning at all. She had already been quoted for a full ignition replacement plus two new keys by someone over the phone, sight unseen.

On arrival the cylinder was worn but the housing was intact, and her key blade was rounded flat on the tips. The correct repair was a cylinder rebuild keyed to her existing key plus one freshly cut key to factory specification, which came in well under the replacement quote and left every lock on the car working on the same key. The phone quote was not dishonest - it was just made without looking at the car, which on an ignition is another word for a guess.

Frequently Asked Questions

How much does it cost to fix an ignition in Plano?

As of August 2026, ignition repair in Plano runs roughly $85 to $450 depending on the failure. Broken key extraction is about $85 to $180, a worn cylinder rebuild is about $170 to $340, a cylinder replacement with a new key is about $250 to $450, and an electrical ignition switch is about $200 to $400. Diagnosis is $75 to $140 and is applied to the repair if you proceed.

Is it cheaper to rebuild the ignition cylinder or replace it?

Rebuilding is usually cheaper and has the added benefit of keeping your existing key working on the whole car. Replacement becomes the better answer when the housing is damaged, the cylinder has seized, or the wear has gone past what new wafers can correct.

Can you fix an ignition without towing the car?

In most cases, yes. Ignition work is mobile work: the tools are portable and the vehicle does not need a lift. The exceptions are faults that require steering column disassembly around airbag components or that have moved into the body wiring, and those belong in a shop.

Why does my car crank but not start after the key turns fine?

That is a security handshake failure rather than an ignition failure. The most common cause is a failed transceiver ring, the antenna coil around the lock that reads the chip in your key. A security light that stays on instead of going out after a couple of seconds is the identifying symptom.

Do I need a new key after ignition work?

Only if the cylinder is replaced rather than rebuilt, or if your existing key is worn enough to damage the new cylinder. A rebuild keyed to your original key needs no new key at all. When a new key is required, it has to be registered to the vehicle before the car will start, and that programming time is included in the quote.

My key will not turn at all. Is the ignition dead?

Not necessarily. Try rocking the steering wheel gently left and right while turning the key, and confirm the car is fully in park. A steering lock under load from wheels turned against a curb will hold the cylinder solid, and that costs nothing to fix.
