The Acura ILX is, underneath the badge, essentially a dressed-up Civic, and for key work that is good news. Its HON66 proximity system is well documented and we stock the blanks, so most ILX visits around Statesboro go smoothly. The catch is a mid-cycle FCC change that trips up owners who order parts online, because two fobs that look nearly identical carry different codes and will not cross over.
We are a mobile automotive locksmith and come to wherever the car is parked, whether that is a driveway near the Market District, a lot off Fair Road, or a space at the Statesboro Crossing. This guide covers what the ILX uses across its run, how a lost-key visit runs, how to spare a fob before you need it, and how to tell a weak coin cell from a real pairing fault.
Which ILX Key Do You Have?
Every ILX is a push-button proximity car, so the question is never whether you have a smart key but which FCC code your exact year wants. Matching the right generation of fob to your VIN is the single step that keeps an ILX visit from turning into a wasted afternoon.
HON66 emergency blade, ID46 chip. FCC: KR5434760 (PN 72147-TX6-A01).
HON66 emergency blade, ID47 chip. FCC: KR5V1X.
HON66 emergency blade. FCC: KR5V2X / KR5V21.
When Every ILX Key Is Gone
Losing every working key to an ILX is a different job from copying a spare, but one we handle on-site. With no fob to act as an authentication seed, the programmer reads the immobilizer data from the car before it can enroll a new proximity fob, working through the security system rather than cloning an existing remote.
It takes more steps than a spare but does not require a tow to the dealer for the ILX. We confirm the correct FCC for your year, pair the new fob, and test that the doors and push-button start respond before we call it done.
Make a Spare ILX Key Before You Need One
If you still have one working fob, a planned spare is the smart move. With a working fob on hand to act as the seed, adding a second proximity key is a short job, and an ILX running on a single fob for years is one drop in a parking lot away from a full lost-all-keys visit. We make and program spares on-site so you do not have to plan around a dealer appointment.
Model-Year and Generation Differences
The 2013-2015 ILX uses a HON66 emergency blade with an ID46 chip on the KR5434760 fob, carried under part number 72147-TX6-A01. The 2016-2018 cars kept the HON66 blade but moved to an ID47 chip on the KR5V1X fob, so even within the early run the electronics changed.
The 2019-2022 ILX moved again, to the KR5V2X (also seen as KR5V21) fob on the same HON66 blade. The blade profile stays familiar across the whole car, but the chip and FCC do not, which is exactly why we confirm by VIN before we drive out: arriving with a KR5V1X fob for a car that wants KR5V2X just burns the trip.
Ignition, Cylinder, and Lock Problems
Because the ILX is a push-button car, there is no traditional ignition cylinder to wear out, so the worn-key-and-tumbler complaints common on older bladed cars are not the story here. What does come up is the HON66 emergency blade and the mechanical door lock it operates, used rarely until the day a fob battery dies. We make sure that backup blade is cut correctly so it actually opens the door when you finally need it.
Is It the Battery or the Programming?
Before assuming the worst, rule out a dead battery. A weak coin cell is the most common reason an ILX fob stops locking from a distance or makes you hold it against the start button to crank. A fresh cell often brings the fob fully back to life.
A true pairing fault is different. If a new battery does not help, if the engine will not start, or if a security light stays lit, the problem is on the immobilizer side and the fob needs to be re-enrolled to the car, which a counter battery swap cannot do.
ILX Smart Key and Push-Button Start
Every ILX uses a proximity fob with push-button start, with the HON66 emergency blade tucked inside for backup entry. With the fob in your pocket the doors unlock on touch and the car starts with the button. When the system stops recognizing it, the cause is usually a weak coin cell first and a pairing fault second. Replacing or adding a fob is a programming job, not just a cut blade, and we verify that lock, unlock, trunk, and push-button start all respond before we leave.
Local ILX Help in Statesboro and Beyond
We serve ILX drivers across Statesboro and all of Bulloch County, coming to homes, workplaces, and parking lots rather than asking you to come to us. Whether the car is parked near the Market District, along East Main Street, off Veterans Memorial Parkway, or out toward US-301, we bring the service to the vehicle and try to arrive with the right fob for your year on the first visit.
Realistic ILX Key Scenarios
Example. A commuter parked at the Statesboro Crossing comes out to a 2017 ILX that will not unlock with the fob. A weak coin cell is the culprit; the KR5V1X fob wakes up with a fresh cell, and we confirm push-button start before they head home.
Example. An owner near the Market District lost both fobs to a 2020 ILX. We confirm the car wants the KR5V2X fob by VIN, read the immobilizer, enroll a fresh proximity key, and test that the doors and start button all respond before we leave.
Example. A driver off Fair Road bought a look-alike remote online for a 2014 ILX and it would not pair. The fob carried the wrong code for the car, so we program the correct KR5434760 part and walk them through how to spot the right one next time.
Before You Call: ILX Checklist
- The year of your ILX, which narrows the chip and FCC immediately.
- The VIN, usually visible through the lower corner of the windshield, so we can confirm the exact fob.
- How many working fobs you have, since a spare is a different job than a lost-all-keys.
- Whether you bought any remote online already, so we can check it carries the right code for your year.
- A photo ID and the registration or title, so we can verify the car is yours before programming.
- Whether the trouble is the fob buttons, push-button start, or the backup blade, so we bring the right tools.
ILX Keys: Dealership or Locksmith?
The Acura dealer can make an ILX key, but it usually means getting the car to the dealership, waiting for an appointment, and leaving it on their schedule. As a mobile locksmith we bring the blanks, the right fob for your FCC, and the programmer to you and do the work in your driveway or a parking lot. The rare job that genuinely needs manufacturer coordination we flag when we confirm your VIN, not after we arrive.

Frequently Asked: ILX Keys
Can you make an Acura ILX key without the original?
Yes. With no fob in hand we read the immobilizer data, build the correct proximity fob for your year, and enroll it against the car, then confirm the doors and push-button start work. It takes more steps than copying a spare but does not require a dealer trip for the ILX.
How do I know which ILX fob I need?
It comes down to the year. The 2013-2015 cars use the KR5434760 fob, the 2016-2018 cars use KR5V1X, and the 2019-2022 cars use KR5V2X. They look similar but do not cross over, so we confirm the exact FCC by VIN before we head out.
I bought an ILX fob online and it won't pair. Why?
ILX owners often buy a look-alike remote that appears identical but carries the wrong code for their year, so it pairs to nothing and the car never recognizes it. We confirm the correct FCC for your VIN and program a fob that actually matches your immobilizer.
My ILX fob stopped working. Is it broken?
Often not. A weak coin cell is the most common reason an ILX fob stops responding at a distance or makes you hold it to the start button. If a fresh cell does not fix it and the engine still will not start, the fob likely needs to be re-enrolled to the car.
Do you program proximity smart keys for the ILX?
Yes. We pair the proximity fob to the ILX smart-key system on-site and verify that lock, unlock, trunk, and push-button start all work before we leave. It is a programming job, not just a cut blade.
Do you come to me in the Statesboro area?
Yes. We are a mobile locksmith and come to your home, workplace, or wherever the ILX is parked across Statesboro and Bulloch County. Call (912) 209-6131 and we will confirm your year and VIN before heading out so we arrive with the right fob.
