2016 Kia Optima (K5 since 2021) Key Replacement in LA

The 2016–2020 Optima (K5 since 2021) uses the same key setup, so everything on this page applies to those years too. The full picture is on the Kia Optima (K5 since 2021) key guide.

2016 Kia Optima (K5 since 2021): key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: 47 (Hitag 3 / NCF2951) — smart-key trims only
Programming: OBD
All keys lost: We can originate new keys on site

Base and mid trims use a turn-key ignition with NO immobilizer (theft class list runs through the 2020 Optima) — a cut key starts the car with no programming. Smart-key trims with push-button start use a Hitag 3 / ID47 fob (NCF2951 family), programmed by OBD; a Kia PIN may be required depending on the tool.

What kind of key does a 2016 Kia Optima use?

It depends on the trim, and that one fact decides almost everything about your replacement. The 2016 Optima (the nameplate became the K5 in 2021) came two ways.

Base and mid trims have a conventional turn-key ignition. These cars have no immobilizer, which means there is no transponder chip in the key that the car has to recognize. A properly cut key turns the ignition and starts the engine. Nothing has to be programmed into the car.

Smart-key trims with push-button start are different. They use a Hitag 3 fob, chip family ID47 (the NCF2951 family). That fob has to be programmed to the car, and we do that through the OBD port. Depending on the programming tool, a Kia PIN code may be needed, and we work that out on the car rather than guessing from the driveway.

The fob also carries a mechanical backup key. That blade opens the door if the fob battery dies, but it does not start the car on its own.

Turn-key trims: mechanical key, no immobilizer, no programming
Push-button trims: Hitag 3 / ID47 smart fob, OBD programming
No NASTF SDRM access is required for programming on this year

Can you duplicate the key, or is it an all-keys-lost job?

Either one works on this car. You do not need an original key in hand for us to make a new one, and a car with every key lost is still something we can handle.

On a turn-key Optima, losing every key is a lighter problem than on most newer cars. Because there is no transponder to match, the job is mainly cutting a key that fits your ignition. That is why replacement on these cars is quick compared with an immobilizer vehicle.

On a smart-key Optima, a spare made from an existing working fob is the simpler path, since the car already recognizes a key. If all fobs are gone, we can still make and program a new one by OBD. It simply involves more steps, so plan for it taking longer than a duplicate.

What if the ignition is damaged or the key sticks?

Two ignition problems come up on this model, and a new key does not fix either one.

The first is theft damage. These turn-key cars have no immobilizer, and they were prime targets in the 2021-2023 Kia theft wave. If your Optima was stolen and recovered, or someone tried and failed, the steering column and ignition are often damaged. A stolen-recovered car usually needs a new ignition lock, and a key made for the old lock will not match it. We replace the ignition cylinder and cut keys to the new one.

The second is plain wear. Ignition lock wafers wear over the years, and the key starts to stick or will not turn. Before replacing anything, we check whether the problem is the key or the lock. A worn key is a smaller fix than a worn cylinder, so it is worth knowing which you have.

Key sticks or won't turn: could be a worn key or worn wafers
Column cover cracked or ignition loose: look for theft damage
Recovered after a theft: expect the ignition lock to need replacing

What affects the cost of replacing a 2016 Optima key?

We don't quote numbers on a web page because the right answer depends on your car. Here is what moves the cost.

The biggest factor is which key system you have. A plain cut key on a turn-key trim is the usually more economical route, since no programming is involved. A smart fob costs more because the hardware itself costs more and it must be programmed.

Next is whether you have a working key to copy from or are in an all-keys-lost situation. After that, the question is whether the ignition lock is fine or has to be replaced. Last, location matters: a mobile visit to your car differs from you coming to our storefront. Give us the trim and ideally the VIN when you call, and we can explain the likely scope before we start.

What do we confirm by VIN, and why call us?

The data on this year is verified: turn-key trims have no immobilizer, and smart-key trims use the Hitag 3 / ID47 fob. What a model-year page cannot tell us is which trim your particular car is, or whether a PIN is needed for the tool we use. We confirm that by VIN and in person, before cutting or programming anything.

Frequently asked questions

Does a 2016 Kia Optima have a transponder chip?

Only the smart-key trims do. Those use a Hitag 3 fob in the ID47 (NCF2951) family. Base and mid turn-key trims have no immobilizer, so their keys carry no chip that needs programming.

Do I need programming for a turn-key 2016 Optima?

No. A properly cut key starts the car without any programming, because there is no immobilizer on those trims.

Can you make a key if I lost all of them?

Yes. All-keys-lost is possible on this car. On a turn-key trim it mostly means cutting a key. On a smart-key trim we make and program a new fob by OBD.

Do I need my original key to get a copy?

No. An original key is not required for this year, though having a working one can make a smart-fob spare simpler.

Is a dealer visit required for a 2016 Optima key?

Not according to our verified data. Programming is done through the OBD port and does not require NASTF SDRM access. We still confirm the details by VIN before starting.

My Optima was stolen and recovered. Will a new key fix it?

Usually not. Theft attempts damage the steering column and ignition, and a recovered car typically needs a new ignition lock. We replace the lock and cut keys to match it.

Why does my Optima key stick in the ignition?

Worn ignition lock wafers are a common cause. The cause can also be a worn key. We check both, so you only pay to replace the part that is actually failing.

Do you come to me, or do I come to you?

Both. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile vans. Call (213) 577-1366 and we'll tell you which makes sense for your situation.

We cover all these cities
