2015 Chevrolet Suburban Key Replacement, Los Angeles

The 2015–2020 Suburban uses the same key setup, so everything on this page applies to those years too. The full picture is on the Chevrolet Suburban key guide.

2015 Chevrolet Suburban: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: 46E (Hitag2 Extended)
Programming: OBD
All keys lost: We can originate new keys on site

HYQ1AA-family proximity fob; push-button start standard on most retail trims. Base LS and fleet/police (PPV) units are reported with a keyed ignition and 46E flip key — push-to-start did not become standard on the PPV until 2021 — so we confirm per vehicle.

What kind of key does a 2015 Suburban use?

Most retail 2015 Suburbans use a smart proximity fob from the HYQ1AA family. You carry it, the truck senses it, and you start the engine with the push button instead of turning a key. Inside the fob is a 46E (Hitag2 Extended) transponder chip, and that chip family is verified against two separate references.

Every one of these fobs also holds a mechanical backup key, a thin blade hidden inside the case. It is there for the day the fob stops talking to the truck, and it is the reason you are rarely locked out for good when the battery dies.

For you as the owner, this means a replacement is more than cutting metal. A new fob has to be programmed to the Suburban, and the blade has to be cut to fit your door lock. That is a different job from copying an older bladed key at a hardware counter. You can see the other model years and the general picture on our Chevrolet Suburban key page.

Can you duplicate a 2015 Suburban key, or is it all keys lost?

Both situations are possible on this truck. If you still have one working fob, we can use it as the original and make an additional one, which is the simpler route. If you have lost every fob, we can still make a new one. That is a longer job, but it does not require a trip to the dealer.

Programming on this Suburban is done through the OBD port under the dash. The data shows no NASTF SDRM registration is required for it, so the work can be done by a locksmith who comes to you.

You call (213) 577-1366 and tell us the year, the model, and whether you have any working fob left.
We confirm the exact key setup for your truck by VIN, because trims differ (more on that below).
We come to the truck with a van, or you come to our Westwood storefront if the Suburban is drivable.
We cut the emergency blade, then program the new fob through the OBD port.
We test the fob for door function and push-button start before we call the job done.

Is it just a dead battery in the fob?

Before you pay for a new fob, check the simple thing first. The commonly reported symptom of a dead fob battery is a dash message saying no remote was detected. If you see that, pull the hidden blade out of the fob and open the door with it. The key blade still works even when the electronics do not.

If the battery is the whole story, replacing it is the lighter-cost fix. If the message keeps coming back with a fresh battery, or the fob has been through water or been crushed, the fob itself is likely failing. Those two cases, water damage and crushing, are the other common reasons Suburban owners call us.

What affects the price of a 2015 Suburban key replacement?

We do not quote numbers on a web page, because the real cost depends on your situation. Here is what moves it:

Whether you have a working fob. Duplicating from an existing fob is usually the more economical route. All keys lost takes more steps.
The fob itself. A proximity fob with a transponder chip costs more than the bladed keys on older vehicles, and that is the main reason a lost-fob replacement stings.
Which trim you have. A base or fleet unit may use a different key, which changes the parts involved.
Where the work happens. Mobile service to your location differs from bringing the truck to the storefront.
How many fobs you want. Making a spare while we are already programming is often smarter than a second visit.

What do we confirm by VIN on this truck?

Here is the honest caveat. Push-button start is standard on most retail trims of the 2015 Suburban. But base LS models and fleet or police (PPV) units are reported with a keyed ignition and a 46E flip key instead. Push-to-start did not become standard on the PPV until 2021. Those reports are not confirmed for every individual vehicle, so we do not assume.

If your Suburban is a base LS or ex-fleet truck, tell us when you call. We confirm by VIN and by looking at the ignition in person before we cut or program anything, so you are not sold the wrong key.

Frequently asked questions

Does a 2015 Chevrolet Suburban have a push-button start?

Most retail trims do, with a smart proximity fob. Base LS and fleet or police units are reported with a keyed ignition instead, so we confirm by VIN before working on yours.

What chip is in a 2015 Suburban key?

The verified chip family is 46E (Hitag2 Extended). The fob is in the HYQ1AA family, and it still has to be programmed to your truck.

I lost all my Suburban keys. Can you still make a new one?

Yes. An all-keys-lost situation is possible on this truck. It takes more steps than copying from a working fob, but you do not have to tow it to a dealer just for a key.

Do you need my original fob to make a copy?

For duplication, yes, an original working key is needed. If you have none, we treat it as an all-keys-lost job instead.

My dash says no remote detected. Do I need a new fob?

Not necessarily. That message is commonly a dead fob battery. The hidden emergency blade will still open the door. If a fresh battery does not fix it, the fob may be damaged.

Is special dealer access needed to program a 2015 Suburban?

Not for the retail setup described in our data. Programming is done through the OBD port and does not require NASTF SDRM registration. Fleet and base units we check individually.

Where can you come to program the key?

Our mobile vans serve 140 cities across Los Angeles and Ventura counties, and you can also bring the truck to our Westwood storefront. Call (213) 577-1366 any hour, or see our car key services overview.
