2007 Hyundai Santa Fe Key Replacement

The 2007–2012 Santa Fe uses the same key setup, so everything on this page applies to those years too. The full picture is on the Hyundai Santa Fe key guide.

2007 Hyundai Santa Fe: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: ID46 (PCF7936/PCF7952)
Programming: OBD
All keys lost: We can originate new keys on site

CM generation — absent from Hyundai's anti-theft list, consistent with a standard immobilizer. ID46 keys program via OBD.

What kind of key does a 2007 Santa Fe use?

The 2007 Santa Fe is a transponder-key vehicle. The key has a metal blade that turns the ignition and a small chip inside the plastic head. The chip belongs to the ID46 family (PCF7936/PCF7952). Our reference sources, transpondery.com and uhs-hardware.com, agree on this, so we treat it as verified for this year. It is not a push-to-start car, so there is no smart fob to worry about.

For you as the owner, that means a key that is only cut will turn the lock but will not start the engine. The immobilizer checks the chip, and if the chip is missing or has not been programmed to the car, the engine will not run. This generation does not appear on Hyundai's anti-theft list, which fits a standard immobilizer setup rather than anything unusual.

The Santa Fe also has a mechanical backup key. If your remote or fob stops working, the blade can still open the door. Starting the car is a separate matter and still depends on the chip.

Key type: transponder, not push-to-start
Chip family: ID46 (PCF7936/PCF7952)
Programming method: OBD port
No NASTF SDRM access required for this setup

Duplicate key or all keys lost: what changes?

Both situations are workable on this vehicle, but they are not the same job.

If you still have a working key, we use it as the original. We cut a new blade, then program the new chip to the car. This is usually the simpler, more economical route, and it is worth doing before the last key goes missing.

If every key is gone, an all-keys-lost job is still possible for this setup. We cut a blade from the lock or by code, then connect to the OBD port and program a new transponder key to the car. Without an original to copy, there are more steps, but the car does not need to be towed to a dealer for this model year.

Call us and give the year, model and your location. If you have a key, tell us its condition.
We confirm the details on your vehicle, including a VIN check where needed.
A technician comes to you in a mobile van, or you visit our Westwood storefront at 10740 Wilshire Blvd.
We cut the blade, test it in the door and ignition, and program the chip over OBD.
We test every key before we finish, including any spare you ask for.

What affects the price of a 2007 Santa Fe key?

We do not quote numbers on a web page, because the final cost depends on the situation. These are the factors that actually move it:

Duplicate or all keys lost. Copying from a working key takes fewer steps than building a key to a car with none.
Where the work happens. A mobile visit to your car costs differently from you coming to the storefront, especially if the car cannot be driven.
Key quality. A properly made ID46 key is not the same product as a cheap clone chip. Low-quality cloned or aftermarket chips are a known cause of intermittent starting trouble.
Number of keys. Programming a spare during the same visit is usually more economical than coming back later.
Ignition and lock condition. If the ignition is worn, that can add work on top of the key itself.
Time of day. Night, weekend and holiday calls are handled differently from a daytime appointment.

Common problems on this generation

Our data lists three problems that come up with this vehicle. The first is worn ignition wafers on high-mileage cars. A new key can feel loose or catch in the ignition, and if the wafers are worn, the issue is the lock rather than the chip. We check this during the visit so you do not pay for a key that will not fix the real problem.

The second is the hardware-store copy. A blade cut without a chip often opens the doors but will not start an immobilizer-equipped car. If you have one of these, it is not defective. It just needs a proper transponder and programming.

The third is a low-quality cloned or aftermarket chip that fails intermittently. The car may start fine for a week and then refuse. If you have a key that behaves this way, bring it or tell us, and we will replace it with a properly programmed one.

What we confirm by VIN, and why call us

The chip family and OBD programming method above are verified for the 2007 Santa Fe. Even so, we confirm the exact key and chip against your VIN, or in person, before cutting anything. Mid-year production changes and past repairs can mean a car does not match the typical setup, and we would rather check than guess.

When you call (213) 577-1366, you reach Wilshire Lock & Key directly, 24 hours a day. We have been in business since 1987, with a storefront in Westwood and mobile vans serving 140 cities across Los Angeles and Ventura counties. There is no dispatch middleman between your call and the technician, and David, the owner and lead technician, 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 a 2007 Hyundai Santa Fe have a chip in the key?

Yes. It uses a transponder key with an ID46 chip (PCF7936/PCF7952). The car will not start with a key that has not been programmed to it.

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

Yes. All-keys-lost is possible for this setup. We cut a blade, then program a new transponder key to the car over the OBD port.

Will a hardware-store key start my Santa Fe?

Usually not. A copy cut without a chip will often open the doors but will not start an immobilizer-equipped car like this one.

Do I need to go to the dealer?

For this model year, no. Programming is done through the OBD port and does not require NASTF SDRM access, so we can handle it ourselves.

Is my Santa Fe push-to-start?

No. The 2007 Santa Fe uses a standard blade-and-chip key turned in the ignition, and it has a mechanical backup key.

My new key feels loose or sticks in the ignition. Is the key bad?

Not necessarily. Worn ignition wafers are a known problem on high-mileage cars. We check the lock during the visit to see whether the key or the ignition is the cause.

Do you confirm anything before cutting the key?

Yes. We confirm the key and chip by VIN or in person first, since individual cars can differ from the typical setup.

We cover all these cities
