Acura RDX & Integra Spare Key in Fort Worth: The Cheapest Locksmith Call You Will Ever Make

Nobody schedules a spare key. It is the automotive equivalent of flossing — universally agreed to be a good idea, universally deferred until something goes wrong at the worst possible moment.

Here is the argument in one line. Adding a second smart key to an Acura RDX or Integra while your existing fob still works costs $220 – $450 in Fort Worth as of July 2026. Doing it after the last fob is gone costs that plus an all-keys-lost surcharge of $50 – $200, takes longer, and often happens at 11 p.m. in a parking garage. Call or text 817-674-2304 with your VIN and it is a twenty-minute driveway appointment.

Quick Answer: Can a Locksmith Add an Acura Spare Key?

Yes, on-site. With one working key present, a mobile locksmith cuts the emergency insert blade for the new fob and registers the new credential to the vehicle through the diagnostic port. No dealership visit, no leaving the car anywhere, no appointment weeks out.

Both the RDX and the current Integra use Acura's proximity Keyless Access system — a smart fob with push-button start and a hidden mechanical blade. The programming path is the same on both; the fob part number differs by model and year, which is why we ask for the VIN rather than guessing from the model name.

Spare Key vs. All Keys Lost: The Actual Math

Prices below come from the Fort Worth ranges published on our car key replacement cost page.

Acura RDX / Integra scenario	Typical Fort Worth range	What is included
Spare smart key, working key present	$220 – $450	Fob, emergency blade cut, programming
Emergency blade cut only (fob already owned)	Quoted on the call	For a fob that was programmed but never cut
All keys lost, smart key	$270 – $650	Above plus decoding the lock with no key to copy
All-keys-lost surcharge (component)	+$50 – $200	The decode-and-derive step
Coin cell replacement	Nominal	Frequently the actual fix
Tow, if you go the dealership route with no key	$75 – $200+	Avoided entirely with mobile service

As of July 2026 these are typical Fort Worth ranges rather than a guaranteed quote. The gap between the first row and the third row is the entire point of this article.

The Detail Almost Everyone Gets Wrong

Inside your Acura fob is a small mechanical blade. Slide the release on the fob body and it comes free. That blade opens the driver's door lock cylinder — and it is the only way into an RDX or Integra when the vehicle's 12-volt battery is flat or the fob is dead and the induction backup fails.

The problem: cutting that blade is a separate operation from programming the fob, and it is skipped constantly. A fob gets programmed, the customer never tries the blade, and an uncut blank sits in a drawer for four years until the night it matters and does nothing at all.

Go get your spare right now. Pull the blade out. If it is a smooth, uncut blank with no wave pattern milled into the edge, it is decorative. Cutting it is a short job and worth doing on its own.

Where the Driver's Door Keyhole Actually Is

Second thing people discover at the worst moment: on the RDX and Integra the exterior door lock cylinder is hidden behind a small cover on the driver's door handle. There is no visible keyhole in normal use. The cover pops off — usually with the tip of the emergency blade itself in a small notch on the underside of the handle — revealing the cylinder.

Practice this once in daylight in your own driveway. It takes ninety seconds and it is far easier than doing it for the first time in the dark while a rideshare meter runs.

Acura Models and Model Years We See Most

RDX, 2019–2026 (third generation)

Keyless Access proximity fob across the range, push-button start, remote engine start on most trims. The most common Acura spare-key call we take in Fort Worth. Straightforward mobile job with a working key present.

RDX, 2013–2018 (second generation)

Also proximity on most trims, with a bladed key on some earlier base configurations. Check the steering column — a key cylinder means bladed, a START button means proximity. Bladed keys land in the $160 – $260 remote-head range instead.

Integra, 2023–2026

The revived Integra uses the current Acura Keyless Access fob and shares its platform underpinnings with the current Civic, so the programming path is familiar. Type S trims use the same key architecture as the base car.

Integra, 1994–2001

Very much still on Fort Worth roads and a completely different animal — mechanical or early transponder keys depending on year, priced in the $50 – $100 basic mechanical or $130 – $220 transponder brackets. Worth mentioning because the model name spans thirty years of key technology.

What the Appointment Looks Like

Ownership verification. Registration or title in your name plus matching photo ID. Texas locksmith work operates under the Texas Department of Public Safety Private Security Program, established in Chapter 1702 of the Texas Occupations Code, and this step is a licensing obligation.

Blade cutting. The emergency blade profile is derived from the factory key code tied to your VIN, then cut on the truck.

Programming. A programmer on the OBD-II port registers the new fob to the vehicle.

Verification. Lock, unlock, tailgate, remote start where equipped, an actual engine start, and — critically — a physical test that the new blade opens the driver's door cylinder.

Twenty to forty minutes for a spare. Compare that to an all-keys-lost visit, which adds non-destructive entry, lock decoding, and a vehicle-imposed security wait.

Bring every fob you own. On many Honda and Acura model years the programming procedure re-teaches the whole registered key list in one session. A fob sitting in a kitchen drawer at home may stop working. This is the single most common avoidable complaint after a key appointment.

Before You Buy a Fob, Check These

Hold the dead fob against the START button and press it. Acura supports a low-power induction read for exactly this situation. If the car powers up, you need a coin cell for a few dollars, not a fob for a few hundred.

Check whether the other fob works. If neither works, suspect the vehicle's 12-volt battery or the receiver rather than two simultaneous fob failures.

Watch what the dash says. A key-shaped warning points at the credential side. Our no key detected page covers that pattern in more depth, and key fob replacement covers the general fob-failure case.

Why the Fob Is Worth Protecting

The reason a spare Acura fob is not a $15 hardware-store item is that it is a security credential, treated as one by federal regulation and by the data-access framework built around it.

FMVSS 114 — Theft Protection and Rollaway Prevention, administered by the National Highway Traffic Safety Administration, is the rule.

Per FMVSS No. 114, each vehicle must have a starting system that, whenever the key is removed from the starting system, prevents the normal activation of the vehicle's engine or motor and prevents either steering, or forward self-mobility, of the vehicle, or both. — NHTSA, Federal Motor Vehicle Safety Standard No. 114

The wording covers electronic credentials, not just cut metal — which is why your proximity fob is legally a key even though it never enters a lock. The standard has also required, since 1991, that vehicles with an automatic transmission having a Park position prevent key removal unless the transmission is locked in Park (NHTSA / Federal Register, FMVSS No. 114).

Who is allowed to program one

Manufacturer key and immobilizer data reaches independent technicians through the National Automotive Service Task Force's Vehicle Security Professional registry, operating the Secure Data Release Model — founded in 2008, now more than 9,000 NASTF participants, with credentialing that requires business registration, a locksmith license, and a criminal background check, and a typical approval window of three to ten days. Trade certification runs through ALOA, and Texas licenses locksmith companies and technicians through the Texas DPS Private Security Program under Chapter 1702.

The payoff shows up in the numbers. The National Insurance Crime Bureau reports U.S. vehicle thefts fell 23.2% from 2024 to 2025 — 850,708 down to 659,880, per the FBI-managed National Crime Information Center — the lowest levels in decades.

If your RDX or Integra is a recent used purchase, note that 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 seller's registration satisfies a key appointment in the meantime.

Frequently Asked Questions

How much is a spare key for an Acura RDX in Fort Worth?

A spare smart proximity fob typically runs $220 – $450 as of July 2026, including the fob, the emergency blade cut, and programming. That is with a working key present; losing every key adds a $50 – $200 surcharge.

Can a locksmith program an Acura Integra key fob?

Yes. The current Integra uses Acura's Keyless Access proximity system, registered through the diagnostic port. A mobile locksmith cuts the emergency blade and programs the fob at your location with no dealership visit.

Is the emergency blade in my Acura fob already cut?

Often not. Cutting the blade is a separate step from programming and is frequently skipped. Pull the blade out of your spare and look — a smooth blank with no milled pattern will not open your door.

Where is the keyhole on an Acura RDX door?

Behind a small cover on the driver's door handle. The cover pops off, usually via a notch on the underside of the handle, to expose the lock cylinder. Practice once in daylight rather than discovering it in the dark.

Do I need to bring both fobs to the appointment?

Yes. On many Honda and Acura model years the programming procedure re-teaches the entire registered key list in one session, so any fob not physically present may stop working afterward.

My Acura fob is dead — can I still start the car?

Usually. Hold the fob against the START button and press it; Acura supports a low-power induction read for dead fob batteries. If the car powers up that way, replace the coin cell instead of the fob.

How long does an Acura spare key take?

About 20 to 40 minutes when a working key exists. All-keys-lost visits take longer because the lock must be decoded and the vehicle imposes its own security wait before accepting a credential.

Is a locksmith cheaper than the Acura dealership for a spare?

Usually, and the difference grows if no working key exists, because that scenario forces a tow of roughly $75 – $200+ before the dealer can begin. With a working key the main saving is the trip and the wait.
