Need a Spare Key for Your 2023 Hyundai Tucson? Here’s the Smart Way to Get One

If you only have one working key for your 2023 Hyundai Tucson, now is the best time to make a spare—before you’re dealing with a lockout or a lost key. The Tucson uses a transponder/proximity system (depending on trim), so a spare usually requires programming, not just cutting a blade. The good news: you typically have multiple safe options in the US market.

Understanding Your Situation

You have a single functioning key/fob (or a key card on some trims) and want a backup to avoid being stranded, reduce emergency replacement costs, and have a second key for another driver.

🚀 Immediate Steps to Take

  1. Identify your key type: (1) proximity smart key fob with push-button start, or (2) traditional key with transponder (rare on 2023 Tucson), and check if you also have an emergency insert key blade.
  2. Gather essentials before calling: VIN, proof of ownership (registration/title), a government ID, and your current working key (having one working key usually lowers cost and speeds programming).
  3. Call the dealer and at least one reputable automotive locksmith for quotes that include: OEM vs aftermarket fob, programming, cutting the emergency blade/insert (if applicable), and any service/mobile fees.

Your Options

Hyundai dealer (OEM smart key + programming)

Cost: $250-$600 Time: Same day to 1-7 days (depends on key availability/ordering)

The dealer orders or supplies an OEM key/fob matched to your 2023 Tucson and programs it to the vehicle. They can also cut the emergency key blade/insert if your fob uses one.

✓ Pros:
  • OEM parts and correct compatibility for your exact trim
  • Dealer-level programming tools and support
✗ Cons:
  • Usually the most expensive option
  • May require an appointment and/or waiting for parts

Licensed automotive locksmith (mobile programming)

Cost: $180-$450 Time: Same day (often within hours if parts are in stock)

A professional locksmith comes to your location or you visit their shop. They supply an OEM or quality aftermarket fob, cut any emergency blade/insert, and program the key to your Tucson.

✓ Pros:
  • Often cheaper than the dealer
  • Convenient mobile service and faster turnaround
✗ Cons:
  • Aftermarket fob quality can vary by supplier
  • Not every locksmith has the correct tools/coverage for newer Hyundai models

Buy your own fob online + pay for programming

Cost: $120-$450 Time: 2-7 days (shipping + appointment)

You purchase a compatible OEM or aftermarket fob online, then pay a dealer or locksmith to cut/program it. Compatibility must match FCC ID/part number and your Tucson’s system.

✓ Pros:
  • Potential savings if you source the fob at a good price
  • You can choose OEM vs aftermarket
✗ Cons:
  • High risk of buying the wrong/locked/used fob that can’t be programmed
  • Some dealers/locksmiths won’t program customer-supplied parts

Add a spare emergency key blade/insert only (if equipped)

Cost: $20-$80 Time: Same day

If your smart fob has an emergency insert key, you can have a duplicate blade cut for door access. Note: this will not start the vehicle unless your Tucson uses a traditional transponder key system (most 2023 Tucsons are push-button start).

✓ Pros:
  • Inexpensive backup for mechanical door entry
  • Helpful if the fob battery dies and you need to unlock the door
✗ Cons:
  • Does not replace a programmed smart key for driving
  • Not all trims/keys use a removable emergency insert

⚠️ What to Avoid

✕ Waiting until you’ve lost your only working key—spare creation is typically cheaper and easier when at least one working key is available.

✕ Buying a used/refurbished fob without verifying it’s reprogrammable for your vehicle (many used smart fobs can be locked to the original car).

✕ Using a generic kiosk/hardware-store key service that can only cut blades but can’t properly program Hyundai smart keys for a 2023 Tucson.

⚠️ Common Mistakes to Avoid

  • Waiting until emergency
  • Not testing spare immediately
  • Buying incompatible aftermarket
  • Overpaying at dealership

Frequently Asked Questions

Can I make a spare key for a 2023 Hyundai Tucson if I still have one working key?

Yes—this is the ideal situation. With one working key, a dealer or qualified automotive locksmith can typically add another programmed key/fob more quickly and at a lower cost than an all-keys-lost scenario.

Do I need to tow the car to the dealer to get a spare key made?

Usually no, as long as you have a working key and the vehicle is accessible. Dealers may require the vehicle present for programming, while many locksmiths can program a spare on-site with mobile service.

Is an aftermarket fob safe to use on a 2023 Tucson?

It can be, but quality and compatibility vary. If you choose aftermarket, confirm the correct FCC ID/part number compatibility for your Tucson and use a reputable locksmith who will stand behind the part and programming.

Will a simple metal key copy start my 2023 Tucson?

In most cases, no. Many 2023 Tucson trims use a proximity smart key system, which requires electronic programming. A cut emergency insert key (if equipped) may unlock the door, but it typically won’t start the vehicle.

What do I need to bring to get a spare key made?

Bring a government-issued ID and proof of ownership (registration/title). You’ll also need your current working key/fob. The provider may also ask for the VIN to ensure correct key/fob selection.

⏱️ Urgency Note: Moderate urgency: If you only have one key, make a spare soon. If that key is lost or damaged, replacement can become significantly more expensive and may require longer downtime.
