2013 Lexus LS Key Replacement

The 2013–2017 LS uses the same key setup, so everything on this page applies to those years too. The full picture is on the Lexus LS key guide.

2013 Lexus LS: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: Varies by trim — we confirm by VIN
Programming: OBD
All keys lost: We can originate new keys on site

LS460/LS600h: HYQ14ACX fob with trunk button (GNE board 271451-5290). Catalog listings disagree on the chip inside this fob — most describe it as 'DST+'/DST80, but at least one lists DST40 — so we match replacements by the fob's FCC ID and board number, not the chip label. All-keys-lost via OBD smart-code reset with professional tools.

What kind of key does a 2013 Lexus LS use?

The 2013 LS has a smart-proximity key and push-to-start ignition. There is no key to turn. The car senses the fob nearby, and you start it with the button. For the LS460 and LS600h, the fob we work with is the HYQ14ACX, which has a trunk button and a GNE board numbered 271451-5290.

For an owner, that changes what a replacement involves. A smart fob is a small radio transmitter with its own circuit board and battery, and the car has to be taught to accept it. Cutting a blade is not enough, and neither is copying a code. The new fob has to be programmed to the car through the OBD port.

The fob also carries a mechanical backup key. That matters on the day the fob stops working, because the backup key lets you get into the car even when the electronics will not cooperate. If you have lost the fob, check whether the backup key is still with you and tell us when you call.

Do you need a duplicate, or are all keys lost?

On this car, making a duplicate is possible when you still have an original working key. Having one in hand is the simpler situation, because the car already knows a good fob and we add another to it.

If every fob is gone, the job is still possible. On the 2013 LS, an all-keys-lost situation is handled with an OBD smart-code reset using professional tools. It takes more equipment and more care than adding a spare, but it does not mean the car has to be towed to a dealer by default. NASTF secure data access is not listed as a requirement for this setup in our data.

Call (213) 577-1366 and tell us the year, model (LS460 or LS600h if you know) and how many fobs you still have.
Send or read us the VIN so we can match the fob by FCC ID and board number.
We come to you with a mobile van, or you visit our Westwood storefront at 10740 Wilshire Blvd if the car can get there.
We program the new fob through the OBD port and, if all keys were lost, perform the smart-code reset first.
We test starting, locking and the trunk button before you drive away.

What affects the cost of a 2013 LS key replacement?

A smart fob costs more to replace than a bladed key, and that is one of the common complaints with this car. We do not quote numbers in a web page, because the real figure depends on your situation, but these are the things that move it:

Whether you have a working original key, or all keys are lost. All keys lost takes more tools and more time.
The exact fob your car needs, once matched by FCC ID and board number.
How many fobs you want programmed, since a spare is cheaper to do while we are already there.
Whether the mechanical backup key needs to be cut as well.
Where the car is. A mobile visit involves travel, while bringing the car to our storefront does not.
The hour. Calls at night or on weekends are answered, but after-hours work can be priced differently.

What is unverified about this fob, and how do we handle it?

Here is the honest part. Catalog listings disagree on the chip inside this fob. Most describe it as DST+ or DST80, but at least one lists DST40. Our own data marks the chip family as unverified, so we will not tell you a chip type with certainty from a web page.

That is why we match replacements by the fob's FCC ID and board number rather than the chip label. We confirm by VIN and by looking at the fob or the car in person. If you buy a fob online first, call us before you pay for it, because a listing that looks right can still be the wrong board.

Common problems on this generation are worth ruling out before you pay for a new fob: a dead battery, which shows up as a 'key not detected' message, and water-damaged or crushed fobs. A dead battery is a much smaller fix than a lost fob.

Frequently asked questions

Can you make a new key for a 2013 Lexus LS if I lost every fob?

Yes, it is possible. For this setup an all-keys-lost job is done through an OBD smart-code reset with professional tools. Call (213) 577-1366 with your VIN and we will confirm the fob you need.

What does 'key not detected' mean on my 2013 LS?

It often means the smart fob's battery is dead, though a damaged or water-affected fob can cause it too. Try the mechanical backup key to get in, and have the fob checked before assuming you need a replacement.

Why do you match the fob by FCC ID instead of chip type?

Catalog listings disagree on the chip in this fob. Most say DST+ or DST80, and at least one says DST40. The FCC ID and board number are more reliable, so we use them and confirm by VIN.

Do I need the dealer for a 2013 Lexus LS key?

Not necessarily. Our data shows OBD programming and no NASTF secure data access requirement for this setup. If your VIN shows something different, we will tell you plainly before any work starts.

Will a spare fob be easier than replacing a lost one?

Yes. With an original key available, a duplicate is straightforward. When all keys are lost, the car needs a smart-code reset first, which is more involved.

Do you come to me, or do I bring the car?

Either works. We have mobile vans that serve the Los Angeles and Ventura county area, and a storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024. See the home page for our service area.

We cover all these cities
