Lost All Keys for Your 2024 Hyundai Tucson? Here’s the Fastest Way Back on the Road

Complete loss of all vehicle keys

🚀 Immediate Steps to Take

  1. Confirm the car is secure and note where it’s parked; if you suspect theft, file a police report and contact your insurer.
  2. Gather documents you’ll likely need: driver’s license, registration/title (or lease paperwork), and the VIN (on the dash or insurance card).
  3. Call ahead to confirm availability and capability: ask a Hyundai dealer or a qualified automotive locksmith if they can originate and program a 2024 Tucson smart key when ALL keys are lost.

Your Options

Hyundai dealership (new OEM smart key + programming)

Cost: $500-$1,200 Time: Varies

A Hyundai dealer can order the correct OEM smart key fob for your 2024 Tucson and program it to the vehicle’s immobilizer system. If the vehicle can’t be driven, you may need towing to the dealer unless the dealer offers mobile programming in your area (varies by dealer). This is the most standardized route, especially when all keys are missing.

✓ Pros:
  • High confidence in compatibility (OEM parts and factory procedures)
  • Can update/clear lost keys from the vehicle during programming
  • Good choice if the car is under warranty and you want documentation
✗ Cons:
  • Often the most expensive option
  • May require towing and/or waiting for parts/appointments

Automotive locksmith (mobile smart key origination + programming)

Cost: $350-$900 Time: Varies

A well-equipped automotive locksmith may be able to come to your Tucson, verify ownership, and program a new smart key on-site—even when all keys are lost. Capability varies by tool access and vehicle security systems, so it’s essential to confirm they can do an ALL-keys-lost job for a 2024 Hyundai Tucson specifically. Some locksmiths can also provide an emergency mechanical key (if your trim uses one) for door access.

✓ Pros:
  • Usually faster because it’s mobile (no towing)
  • Often less expensive than the dealer
  • Convenient if the car is at home, work, or a parking garage
✗ Cons:
  • Not all locksmiths can program late-model Hyundai smart keys
  • Aftermarket fobs vary in quality; compatibility must be confirmed

Towing to dealer vs. on-site service (logistics decision)

Cost: $0-$250 (towing varies; may be covered by roadside assistance) Time: Varies

When all keys are lost, the biggest delay is often logistics: getting the vehicle to the place that can program it. If a dealer is the only viable programming option, towing may be required. If a qualified locksmith can program on-site, you can usually avoid towing and reduce downtime.

✓ Pros:
  • Lets you choose the best programming option even if the car can’t move
  • Roadside assistance may reduce or eliminate towing cost
  • Can be the difference between same-day vs multi-day resolution
✗ Cons:
  • Towing adds cost and coordination
  • Some garages/structures complicate towing or mobile access

⚠️ What to Avoid

✕ Paying upfront for a “universal key fob” online—2024 Hyundai Tucson smart keys typically require exact compatible hardware and proper programming; many cheap fobs won’t work or can’t be added in an all-keys-lost scenario.

✕ Using a non-automotive kiosk or hardware store key service—most can’t handle Hyundai immobilizer smart-key programming, especially when all keys are missing.

✕ Skipping ownership verification—reputable providers will require ID and proof of ownership; anyone willing to program without it is a red flag.

⚠️ Common Mistakes to Avoid

  • Calling dealer first without getting quotes
  • Not checking insurance coverage
  • Rushing to tow to dealership
  • Not considering mobile locksmiths

Frequently Asked Questions

Can I start my 2024 Hyundai Tucson without the key fob if I lost all keys?

In most cases, no. The Tucson’s immobilizer requires a programmed smart key to authorize starting. Even if you can unlock the door, the vehicle typically will not start without a properly programmed fob.

If someone finds my lost key fob, can they steal my Tucson?

A found fob could potentially unlock and start the vehicle if it’s still authorized. When you get a replacement, ask the provider to delete/disable all missing keys during programming so the lost fob can no longer start the car.

Do I need to tow my 2024 Tucson to the dealer?

Not always. If you choose a dealer and they require the vehicle present for programming, towing may be necessary. A qualified mobile automotive locksmith may be able to program a new smart key on-site and avoid towing—confirm they support all-keys-lost programming for a 2024 Tucson.
