Honda and Acura Ignition Repair Cost in Plano (2026)

Hondas and Acuras run for a very long time, which is exactly why their ignitions wear out. A 2008 Accord or a 2010 CR-V on its second or third owner has turned that key tens of thousands of times, and eventually the wafers inside the lock cylinder stop lining up. The key sticks, you jiggle it, and one morning in a Plano parking lot it will not turn at all. For mobile Honda and Acura ignition repair anywhere in Plano, call or text (945) 307-3827.

Quick Answer

As of September 2026, most Honda and Acura ignition repairs in Plano cost $170 to $450. A worn lock cylinder rebuilt to your existing key typically runs $170 to $340, a full cylinder replacement with a new key cut runs $250 to $450, and an electrical ignition switch replacement runs $200 to $400. Diagnosis is $75 to $140 and is applied to the repair if you go ahead. If a new cylinder means a new key, add key registration for the immobilizer.

After-hours or emergency response	Surcharge applies	-	Confirmed on the phone before dispatch

Those numbers are ranges, not a menu price, because the same symptom can come from three different parts. The honest way to price a Honda ignition is to find out which part failed first. That is what the diagnosis line is for, and why it is credited toward the repair.

What Actually Fails on a Honda Ignition

Honda ignitions have two halves that fail independently, and knowing which half is failing is the whole game.

The mechanical half: the lock cylinder

The lock cylinder is the part your key goes into. Inside it is a stack of small wafers that ride on the cuts of your key. When the key is right and the wafers are healthy, they all drop flush and the cylinder turns. Over years of use, two things wear: the key itself, which loses the sharp edges on its cuts, and the wafers, which wear where they ride.

The classic Honda symptom is a key that turns fine some days and needs to be wiggled on others, usually worse in summer heat and after the car has sat. That is almost always a worn cylinder, a worn key, or both. It is especially common on the 2003 to 2012 generations of the Accord, Civic, CR-V, Odyssey and Pilot, simply because there are so many of them still on Collin County roads with high mileage.

A cylinder that still turns with effort can usually be rebuilt to your existing key - the $170 to $340 line. A cylinder that has seized, or is worn past rebuilding, gets replaced, and the replacement is keyed either to your current key or to a newly cut key - the $250 to $450 line.

One Honda-specific trap: if your key itself is badly worn, a technician may decode the cylinder and cut a fresh key to factory specification rather than copying your worn one. A copy of a worn key reproduces the wear. That is also why a cheap hardware-store duplicate of an old Honda key often makes a marginal cylinder worse.

The electrical half: the ignition switch

Behind the lock cylinder sits the electrical ignition switch, which actually sends power to accessories, the ignition circuit and the starter. When it fails, the key turns normally but the car does something wrong: no crank, dash lights that flicker, accessories that cut out, or a stall while driving.

That is the $200 to $400 line. On some models the switch is a separate part from the cylinder; on others it is serviced as part of an assembly. Which one your car has is one of the reasons we ask for the VIN before quoting.

If the key turns and everything lights up but pressing into START does nothing, our guide on a key that turns with dash lights but nothing at start walks through how to separate an ignition switch from a starter or a neutral safety switch.

The immobilizer antenna

Every Honda and Acura with a chipped key has an antenna ring wrapped around the front of the ignition cylinder. It reads the chip in the key. When the ring fails, the key turns, the dash lights up, and the green key-shaped immobilizer light flashes while the engine refuses to start or starts and dies.

That is the $180 to $350 line. It is also why a Honda ignition is never purely mechanical - any time the cylinder comes out, that antenna has to be handled correctly or you trade one no-start for another. If your symptom is specifically the flashing key light, our page on Honda and Acura immobilizer key programming covers that side in detail.

Push-Button Hondas and Acuras

Many newer Hondas and most newer Acuras start with a button, not a key. There is no lock cylinder to wear out, so the ignition costs above mostly do not apply. The "ignition" failures on push-button cars are different:

• The key is not detected. Usually a weak fob battery, a damaged fob, or an antenna issue. Start with the fob before anything else.
• The start/stop button itself fails. Less common, and diagnosed by checking what the car sees when the button is pressed.
• The brake pedal switch fails. Push-button cars need to see the brake pressed before they crank. A failed brake switch looks exactly like a dead start button.
• A steering lock or related module fault on certain earlier push-button models.

Those are priced as diagnosis plus the specific part, and most land inside the ranges in the table. If your push-button car shows a key warning, read our guide to a proximity smart key that is not detected first.

What Moves the Price Inside Each Range

Model and generation

A turn-key Civic or Fit is at the lower end. An Odyssey, Pilot, or an Acura MDX or TL is usually higher, because of column design, trim removal, and in some cases steering column parts that take longer to access safely.

Rebuild versus replace

A rebuild keeps your existing key and is usually cheaper. A replacement is faster to predict and sometimes the only option. When a replacement cylinder takes a newly cut key, that key also has to be registered to the immobilizer, which is the $120 to $230 registration line. We will tell you which way your car is going after diagnosis, not before.

Whether the key is also worn

A worn key in a rebuilt cylinder is a repair that fails again. If your key is rounded off, we cut a fresh one to specification and register it. That adds cost today and saves you the same call next year.

When and where

The work is mobile. The ranges assume a normal weekday call in Plano, Frisco, McKinney, Allen, Richardson or Garland. After-hours and weekend calls carry a surcharge confirmed before dispatch.

Cost by Model Family

Because Honda built so many turn-key cars on shared designs, costs cluster by family rather than by individual model. These are the patterns we see, all inside the table ranges above.

Civic, Fit and Insight

Compact columns, easy trim removal, and cylinders that are widely available. A worn-cylinder rebuild on a 2006 to 2015 Civic is typically at the low end of the $170 to $340 rebuild line. The most common add-on is a fresh key cut to specification, because Civic keys that have been on a busy keychain for a decade are usually worn as badly as the cylinder.

Accord and Crosstour

The Accord is the car we see most often for sticking ignitions, especially the 2003 to 2012 generations. Most rebuilds land in the middle of the range. On higher-trim Accords that moved to push-button start, the cylinder costs in this article do not apply at all; see the push-button section below instead.

CR-V, Element and HR-V

Tall crossover columns and a lot of daily use. The CR-V in particular gets driven hard by families, and its keys pick up grit from diaper bags and sports gear, which accelerates cylinder wear. Mid-range rebuilds are typical, and a combined cylinder-plus-new-key job lands near the middle of the replacement line.

Odyssey, Pilot and Ridgeline

Larger vehicles with more trim to remove and, on some years, more involved column access. These tend toward the upper half of each range. The Odyssey also has a reputation for keys that get handed to many drivers, so we often see both a worn cylinder and a key that needs cutting to specification in the same visit.

Acura TL, TSX, RDX and MDX

Acura turn-key models use Honda-family cylinders and immobilizers, but with more interior trim and, on several models, more careful column disassembly. Expect the upper half of each range. Many later Acuras are push-button, so check which kind of start your car has before comparing quotes.

Repair Now or Wait?

A sticking Honda ignition is one of the few car problems that almost always gets more expensive the longer you wait. The progression is predictable:

1. The key sticks occasionally. A rebuild keyed to your existing key is usually possible and sits at the low end.
2. The key sticks every day and needs jiggling. Still usually rebuildable, but the wafers are further gone and your key is wearing faster.
3. The key will not turn at all. Now the cylinder may have to be drilled or replaced, and the car may need to be keyed and registered fresh. You are at the top of the replacement line, possibly with a tow if the car was stuck somewhere inconvenient.
4. The key snaps inside the cylinder. Extraction plus whatever step three would have cost.

Most people call at step three. The cheapest time to call is step one.

Plano-Area Scenarios

These are typical patterns rather than individual customer stories.

The Accord in a Legacy West garage that will not turn. The key goes in, stops halfway, and will not budge after a day of summer heat. Almost always a worn cylinder. If it still turns with effort, a rebuild keyed to the existing key; if seized, a replacement with a fresh key registered to the immobilizer.

The CR-V that stalls on Coit Road. The key turns fine but the engine cuts out over bumps and the dash flickers. That pattern points at the electrical switch rather than the cylinder.

The Odyssey with the flashing green key. Turns, lights up, will not start, and the key light blinks. That is an immobilizer read problem - antenna, key chip, or key registration - not a worn cylinder.

The snapped key in a Civic. The blade broke off in the cylinder. Extraction first; if the cylinder is healthy, a new key is cut and registered and the ignition itself stays.

What Not to Do

• Do not spray lubricant into the cylinder. Graphite or a light dry lubricant has its place, but penetrating oils attract grit and can make a marginal Honda cylinder fail faster.
• Do not force the key with pliers. A snapped key turns a rebuild into an extraction plus a new key.
• Do not copy a worn key. A duplicate reproduces the wear. Ask for a key cut to specification.
• Do not keep driving a car that stalls. An intermittent switch that cuts the engine at speed is a safety problem, not an inconvenience.

Locksmith or Dealer?

A Honda or Acura dealer can replace the ignition. Expect a tow, a service appointment, and parts ordered in. A mobile automotive locksmith rebuilds or replaces the cylinder where the car sits, cuts the key, and registers it to the immobilizer in the same visit.

Frequently Asked Questions

How much does it cost to fix a Honda ignition that won't turn in Plano?

As of September 2026, most worn Honda lock cylinders are rebuilt to the existing key for $170 to $340, or replaced with a new key cut for $250 to $450. Diagnosis runs $75 to $140 and is applied to the repair.

Will I need a new key if my Honda ignition cylinder is replaced?

Sometimes. A replacement cylinder can often be keyed to your existing key. If your key is badly worn, or the new cylinder takes a new key, that key has to be cut and registered to the immobilizer, which adds roughly $120 to $230.

Why does my Honda key work some days and not others?

That pattern is the classic sign of worn wafers in the lock cylinder, a worn key, or both. It usually gets worse in heat. It is cheapest to fix while the key still turns, because a rebuild is less expensive than a replacement.

My Honda key turns but the green key light flashes and it won't start. Is that the ignition?

Not the mechanical ignition. A flashing green key light means the immobilizer is not reading or not accepting the key. That is the antenna ring, the key chip, or key registration.

Do push-button Hondas have ignition problems?

They do not have a lock cylinder to wear out, but they can have key detection, start button, brake switch or steering lock issues. Those are diagnosed differently and priced as diagnosis plus the specific part.

Can you fix a Honda ignition at my home or work?

Yes. Ignition rebuilds, replacements, key cutting and immobilizer registration are all done on site anywhere in Plano and the surrounding Collin County cities.
