2001 Hyundai Elantra Key Replacement

The 2001–2006 Elantra uses the same key setup, so everything on this page applies to those years too. The full picture is on the Hyundai Elantra key guide.

2001 Hyundai Elantra: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: ID46 (PCF7936)
Programming: OBD
All keys lost: We can originate new keys on site

ID46 applies to immobilizer-equipped cars (HYN6T14-family keys). US immobilizer fitment in this era was trim-dependent and plain-key cars exist — we verify chip-or-no-chip on the vehicle before cutting.

What key does a 2001 Elantra use, and what does that mean for you?

The key on an immobilizer-equipped 2001 Elantra is a transponder key. Inside the plastic head sits a small chip, identified in our data as ID46 (PCF7936), part of the HYN6T14-family of keys. When you turn the ignition, the car reads that chip. If the code doesn't match what the car has stored, the engine won't start, even if the metal blade turns the cylinder perfectly.

This is not a push-to-start car. It uses a traditional blade in a traditional ignition, and there is a mechanical backup key for the car as well. So the job has two halves: cutting the blade correctly and programming the chip to the car.

One caveat we want to be upfront about. Fitment of immobilizers on US cars from this era depended on trim level, and plain-key Elantras from this period do exist. The ID46 chip applies to the immobilizer-equipped cars. So before we cut anything, we confirm on your actual vehicle whether it has a chip or not. That check saves you from paying for a chip you don't need, or from getting a key that cuts but won't start the car.

Duplicate key or all keys lost: what's different?

Both are possible on this car, and neither one requires a trip to a dealer for the work described in our data. The programming is done through the OBD port, and no special manufacturer-registry access is required for this setup.

Duplicate: if you still have a working original key, we can use it as the reference to cut and program a new one. That is the simpler, usually more economical route, which is why we encourage people to copy a key before the last one disappears.
All keys lost: this is still possible. We cut a key from the car itself, then program a new chip to the vehicle through OBD. It takes more steps and more time than a straight copy, so expect it to cost more.
Spare vs. replacement: if a key is lost, we can program the new key so the vehicle is set up with the keys you now hold. Ask us about this when you call.

How we handle it, step by step

Whether you're at home in Westwood or stranded somewhere else, the process is the same.

You call (213) 577-1366 and tell us the year, model, and whether you have any working key.
We confirm by VIN or in person whether your Elantra has an immobilizer, so we know whether it needs a chip.
We cut the blade to match your ignition and doors, working from your original key or from the car if all keys are lost.
We program the ID46 chip to the car through the OBD port.
We test the key in the ignition, the door locks, and the trunk before we leave or hand it over.

Locked out or need a locksmith now?

We answer around the clock, every day of the year.

What affects the price of a 2001 Elantra key?

We don't quote numbers on a web page because the real figure depends on your situation. Here is what moves it:

Whether you have a working key to copy or all keys are lost.
Whether your car has an immobilizer, which decides if a chip and programming are needed at all.
Ignition condition. High-mileage cars can have worn ignition wafers, and a new key won't turn smoothly if the lock itself is tired.
Where the work happens: our Westwood storefront or one of our mobile vans coming to you.
Time of day. We answer 24/7, and after-hours calls are a different job from a daytime appointment.

Problems we see on cars like this

Three issues come up with this generation of Elantra. First, worn ignition wafers on high-mileage cars, which cause a key to stick, turn roughly, or fail to turn at all. That is a lock repair issue, not a key issue, and we can look at it during the same visit.

Second, hardware-store copies. A cheap blade cut without a chip will often open the doors but will not start an immobilizer-equipped car. People buy these, think they have a spare, and find out in a parking lot that they don't.

Third, low-quality cloned or aftermarket chips that fail intermittently. The car starts one day and not the next. If you've got a key like that, bring it by and we can tell you whether it's the chip or something else.

Wilshire Lock & Key has been in business since 1987, with a storefront at 10740 Wilshire Blvd and mobile vans. You deal with one company, not a dispatch middleman, and David oversees the work. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start.

Frequently asked questions

Does every 2001 Hyundai Elantra have a transponder chip?

Not necessarily. Immobilizer fitment in the US during this era depended on trim level, and plain-key cars exist. The ID46 chip applies to immobilizer-equipped cars. We verify chip or no chip on your vehicle before cutting.

What chip does the 2001 Elantra use?

Immobilizer-equipped cars use an ID46 (PCF7936) chip, found in HYN6T14-family keys. Our data for this chip is verified.

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

Yes. All-keys-lost is possible for this car. We cut a blade for the ignition and program a new key to the vehicle through the OBD port.

Do I need to go to the dealer?

For the setup described in our data, no. Programming is done via OBD and does not require a special registry credential, so we can handle it ourselves at our storefront or by mobile van.

Is it cheaper to copy a key than replace one from scratch?

Usually, yes. A copy from a working original is typically the more economical route. All keys lost involves more steps, so it generally costs more.

My copy from a hardware store opens the door but won't start the car. Why?

That copy was likely cut without a chip. On an immobilizer-equipped Elantra, the car needs to read a programmed transponder before the engine will run. A blade alone won't do it.

My key sticks or won't turn in the ignition. Is that the key?

It may be the ignition. Worn ignition wafers are a common problem on high-mileage cars of this era. We can check whether the key or the lock is the issue.

Is there a push-to-start version of the 2001 Elantra?

No. This is a traditional key and ignition car, and there is a mechanical backup key available.
