Acura ILX & TSX Key Replacement in Fort Worth (2009–2018 Bladed Keys)

If you drive a 2009–2018 Acura ILX or TSX in Fort Worth and you've lost your key, there's a piece of good news buried in the model year: these cars use a bladed transponder key, not a proximity smart fob. That single fact puts your replacement in the cheaper half of the price sheet and makes the job faster than an owner who's been reading about $400 smart keys expects.

As of July 2026, a replacement key for these two models runs $130 – $220 for a standard transponder key and $160 – $260 for the remote head key with lock, unlock, and trunk buttons built into the head. If every key is gone, add the $50 – $200 all-keys-lost surcharge, because the lock has to be decoded before anything can be cut. Call or text 817-674-2304 with the VIN and we'll confirm which key your specific car takes before quoting.

Quick Answer: Can a Locksmith Replace an Acura ILX or TSX Key?

Yes — cut and programmed on-site, without the car ever moving. A mobile automotive locksmith can replace an Acura ILX or TSX key in your driveway, an office lot, or wherever the car is parked, including the all-keys-lost case where no working key exists.

What determines the job:

• Model year and body. The second-generation TSX (2009–2014, including the Sport Wagon) and the first-generation ILX (2013–2015) plus the refreshed ILX (2016–2018) all use a high-security bladed key with an embedded transponder chip. Higher trims add a remote head.
• Whether a working key exists. With one, we add a key to the immobilizer. Without one, we decode the door lock to derive the cut, then reach the immobilizer through the diagnostic port.
• Which remote your trim carries. ILX and TSX remotes vary by trim and year — button count and FCC ID both matter. The VIN settles it.

What an Acura Key Costs in Fort Worth

These are the typical Fort Worth ranges from our car key replacement cost page, narrowed to the keys these two models actually use.

Acura ILX / TSX key type	Typical Fort Worth range	Notes
Standard transponder chip key	$130 – $220	Bladed key, no remote buttons; cut and chip-programmed
Remote head key	$160 – $260	Blade plus integrated lock/unlock/trunk remote
All-keys-lost surcharge	+$50 – $200	Added when no working key exists; lock must be decoded first
Luxury / European smart key	$300 – $700+	Not applicable to these models — listed so you can rule it out

These are typical Fort Worth ranges, not a guaranteed quote. The reason the last row matters is that Acura is a luxury badge, and owners often assume luxury smart-key pricing applies. On a 2009–2018 ILX or TSX it does not. You're paying for a bladed key on a Honda-family immobilizer, and the price reflects that.

Why These Acuras Are Easier Than Newer Ones

Acura's bladed-key era ended on these platforms. Later ILX model years and the RDX, MDX, and TLX moved to proximity smart systems that cost more to replace and take longer to program. If you're inside the 2009–2018 window on an ILX or TSX, you have the last generation of Acura that a mobile technician can handle with straightforward key-cutting equipment and a diagnostic session.

Three practical consequences:

The blade can be cut from code or by decoding the lock. No working key needed. A high-security blade is milled on both edges rather than cut on the shoulders, which requires a proper laser-style cutter — but it's a solved problem, not an exotic one.

The transponder is programmed through the OBD-II port. The immobilizer accepts a new key credential in a normal diagnostic session. There's no module removal, no bench work, no soldering.

Remote pairing is part of the same visit. If your trim has a remote head, the lock/unlock/trunk functions are paired in the same session rather than requiring a separate procedure.

That combination is why we can quote these confidently over the phone once we have the VIN.

The All-Keys-Lost Path on an ILX or TSX

Losing every key is not a different vehicle problem — it's a different amount of work. Here's what actually happens on-site.

Ownership verification first. Texas locksmith work falls under the Texas Department of Public Safety Private Security Program established in Chapter 1702 of the Texas Occupations Code. Before anything else, the technician confirms your current registration or title matches your photo ID. No exceptions, and you should be suspicious of anyone who skips it.

Deriving the blade. With no key to copy, the cut comes either from the vehicle's factory key code (retrieved by VIN) or by decoding the driver's door lock directly. Decoding is the more common route on cars this age because factory code availability varies.

Cutting the high-security blade. A milled blade takes a few minutes on a proper machine and has to be dimensionally correct — a blade that's close but not right will turn the door lock and bind in the ignition.

Immobilizer access. With no existing credential to authenticate against, reaching the immobilizer takes a security wait period on-site. The technician isn't idle; the vehicle is enforcing a delay by design. Plan for the appointment to run longer than a simple spare.

Programming and verification. New key written to the immobilizer, remote paired if applicable, then a full test — door locks, trunk, ignition, and a real engine start.

Budget sixty to ninety minutes for a well-run all-keys-lost visit on these models. Our lost car key with no spare guide covers the same process across other makes if you want the general version.

Get the Second Key While You're There

The single most common regret we hear from Acura owners is that they replaced one key and stopped. Programming a second key during the same visit is dramatically cheaper than a separate visit later, because the expensive parts of the job — the trip, the ownership verification, the immobilizer session — are already paid for.

More importantly, a second key means you never face the all-keys-lost surcharge again on this car. On an ILX or TSX that's a real amount of money, and it's the difference between a scheduled appointment and a stranded evening. The economics are laid out in our spare car key guide.

Immobilizer Symptoms That Aren't a Lost Key

Sometimes the key isn't lost — it just stopped starting the car. On these Acuras, watch what the security light does:

• Security light flashes and the engine cranks but won't fire. The immobilizer isn't recognizing the transponder. Causes range from a cracked chip inside the key head (these get dropped a lot) to a failing antenna ring around the ignition cylinder.
• Security light stays solid with the key on. A system-side fault rather than a key-side one. Worth diagnosing before buying keys.
• The key works intermittently, better in some positions. Usually a weak antenna ring read or a chip loose in a cracked key head.
• The remote stopped working but the car still starts. Purely a remote issue — battery, or the remote needs re-pairing. Not an immobilizer problem at all. See key fob programming.

Telling us which of those you're seeing changes what we bring. A cracked key head is a key job. A dead antenna ring is not, and we'll say so rather than sell you keys that won't fix it.

Buying a Key Online for Your Acura

The temptation is real — ILX and TSX key blanks are widely listed online for a fraction of a dealership price. Two cautions.

FCC ID and chip type have to match your exact car. "Fits Acura TSX 2009-2014" listings frequently cover multiple part numbers, and the wrong transponder type simply won't be accepted by the immobilizer no matter how well it's cut. The VIN tells us the right part; a listing title doesn't.

Blade quality on cheap high-security blanks is inconsistent. A soft or dimensionally-off blank can be cut correctly and still bind in the ignition, or wear rapidly and leave you back where you started in a year.

If you already bought one, bring it and tell us the part number on the call. Sometimes they're fine. When we supply the key, the part and the programming are a single job with a single point of accountability.

Mobile Service Across Fort Worth

ILX and TSX owners call us from all over the metro — TCU and the near south side, downtown and the medical district, Ridgmar and the west side, Alliance and far north Fort Worth — as well as Arlington, Bedford, Hurst, Euless, Keller, Haltom City, and North Richland Hills. The full list is on our service areas page.

The vehicle needs to be accessible. Gated communities, parking garages with height restrictions, and secured office lots are all workable — just tell us at booking so the technician can meet you at the entrance rather than circling.

How a Locksmith Legitimately Gets Your Acura's Key Data

Owners occasionally ask a version of this question with real suspicion behind it: if the car is supposed to be hard to break into, how is a locksmith allowed to make a key for it? It's a good question and it has a documented answer.

Manufacturer key codes, PINs, and immobilizer data are not open information. They're released through a controlled channel — the National Automotive Service Task Force's Vehicle Security Professional registry, which operates the Secure Data Release Model. Founded in 2008, the registry now has more than 9,000 NASTF participants working inside it.

Per NASTF's Secure Data Release Model, access to key programming, immobilizer services, and other security-sensitive functions is granted only after business validation, criminal background checks, confirmation of professional standing, and proof of the vehicle owner's authority — with transactions monitored for unusual activity. — NASTF VSP Registry (SDRM)

Becoming credentialed isn't a formality. NASTF requires documentation of business registration, a driver's license, a locksmith license, and consent to a background check, with a typical approval window of three to ten days and occasionally as long as two weeks. That process is what stands between your ILX and someone who'd like a key to it.

Layered on top is state licensing. Texas regulates locksmith companies and technicians through the Texas Department of Public Safety Private Security Program, authorized under Chapter 1702 of the Texas Occupations Code. Trade-side certification runs through ALOA, the Associated Locksmiths of America.

The security math actually works

Whether all this gating accomplishes anything is measurable. The National Insurance Crime Bureau reports U.S. vehicle thefts fell 23.2% from 2024 to 2025 — from 850,708 to 659,880 — based on reports entered into the FBI-managed National Crime Information Center database, the lowest levels in decades. Transponder immobilizers of exactly the kind in your Acura are part of why that curve bent.

For you as an owner, the practical takeaway is a short screening test. A locksmith who verifies your ownership documents, can speak to their DPS licensing, and understands why they're asking is operating inside that system. One who offers to skip the paperwork as a courtesy is telling you they operate outside it — and the same shortcut that's convenient for you is convenient for whoever wants your car next.

If you bought your ILX or TSX recently, check the title before you call. The Texas Department of Motor Vehicles requires the vehicle to be titled in the buyer's name within 30 days of the sale date, with delinquent-transfer penalties beyond that. A signed title plus the prior registration will get the key work done in the meantime, but the transfer still needs finishing.

Worth knowing on the vehicle side too: the immobilizer your Acura relies on exists partly because of FMVSS 114, the theft-protection and rollaway-prevention standard NHTSA administers, which requires a starting system that prevents engine activation whenever the key is removed (NHTSA, FMVSS No. 114). That requirement is the reason a correctly cut blade alone won't start the car — the chip has to be registered too.

Frequently Asked Questions

Can a locksmith make an Acura ILX key with no working key?

Yes. The blade is derived from the vehicle's factory key code by VIN or by decoding the driver's door lock, then cut and programmed to the immobilizer through the diagnostic port. Expect the all-keys-lost surcharge of $50 – $200 and a longer appointment, since the vehicle enforces a security wait period before the immobilizer will accept a new credential.

How much is a replacement key for a 2013 Acura TSX in Fort Worth?

A standard bladed transponder key typically runs $130 – $220 and a remote head key $160 – $260 in the Fort Worth market, including cutting and programming. Which one you need depends on trim — the VIN confirms it before we quote.

Does the Acura ILX use a smart key or a bladed key?

The 2013–2018 ILX uses a bladed transponder key, as does the 2009–2014 TSX. Proximity smart keys appear on Acura's larger and later models such as the MDX, RDX, and TLX. That distinction is why replacement on the ILX and TSX costs meaningfully less.

Will a new key erase my existing Acura key?

Adding a key normally writes a new credential without disturbing existing ones. If the immobilizer's key table is full from prior owners, it may need to be cleared and re-taught — in which case every key you want to keep working must be physically present at the appointment.

My Acura's security light is flashing and it won't start. Is the key bad?

That flashing light means the immobilizer isn't recognizing the transponder. It's commonly a cracked key head with a damaged chip, but it can also be a failing antenna ring around the ignition. Both are diagnosable on-site, and only one of them is fixed by a new key.

How long does an Acura key replacement take in Fort Worth?

With a working key present, about thirty to forty-five minutes. With no working key at all, plan on sixty to ninety minutes, most of which is the vehicle's enforced security wait before the immobilizer accepts programming.

Can you cut a key for an Acura TSX Sport Wagon?

Yes. The Sport Wagon shares the second-generation TSX key system, so the blade, transponder, and programming procedure are the same as the sedan.

Is a locksmith cheaper than an Acura dealership for a key?

Usually, because there's no tow to the service lane, no multi-day wait for an appointment, and no parts-counter markup. The trade-offs between the two routes are compared in our auto locksmith vs dealership guide.
