Did You Lose Your Only Hyundai Key?
If you're searching "Hyundai key replacement Stuart FL" right now, here's what you need to know immediately. Stuart Locksmiths replaces Hyundai keys on-site across Martin County, costs run $85 to $275 depending on key type, and most jobs are finished in 20 to 45 minutes flat.
Hyundai makes some of the most popular vehicles on the road in Stuart right now. The Elantra, Tucson, Sonata, Santa Fe, and Palisade are everywhere from the US-1 corridor to the neighborhoods off Salerno Road. And every single one of those models uses a transponder chip or smart key that can't be replaced at a hardware store. You need a locksmith with the right programming equipment, or you're going to the dealership and waiting days.
We're not the dealership. Stuart Locksmiths comes to you, whether you're stranded at the Treasure Coast Square parking lot, stuck at the boat ramp on St. Lucie Boulevard, or sitting in your driveway off Indian Street. One call to (772) 362-5731 and a technician is heading your way.
What Type of Hyundai Key Do You Have?
Not all Hyundai keys are the same, and the type you drive determines the cost and programming method. Here's a quick breakdown.
Hyundais from 2000 to roughly 2011 used basic transponder keys. The key has a chip embedded in the plastic head, but it's a simpler system. These are the least expensive to replace, typically $85 to $130. Models from 2012 onward often use a flip key fob combo, where the key blade folds into the remote housing. That's a more involved replacement, running $120 to $195.
Then there's the Hyundai Blue Link smart key, also called a proximity key or push-to-start fob. The Tucson, Sonata, Palisade, and newer Elantra models have these. No physical key blade you insert into an ignition. The car senses the fob and you push a button. Replacing one of these runs $175 to $275 and requires specialized equipment to program. Dealers charge $350 to $500 for the exact same job, then make you wait 2 to 5 business days for the part.
We carry blank key stock for the most common Hyundai models on hand in our service vehicles. For newer smart keys, we can typically source and program within the same day in Stuart.

According to the Associated Locksmiths of America, automotive key programming now accounts for 41% of all locksmith service calls nationally, with transponder and smart key work driving the bulk of that volume. Dealerships hold a near-monopoly perception on this work, but independent licensed locksmiths with OEM-grade programming tools can do the same job for 30-50% less.

How Our Hyundai Key Replacement Process Works
- Call Us and Give Us Your Vehicle Info - When you call (772) 362-5731, we'll ask for your Hyundai's year, model, and VIN. That last part matters. The VIN tells us the exact key configuration, so we show up with the right blank. No guessing, no second trips.
- We Come to You Anywhere in Stuart - Our mobile unit comes to your location. Palm City, Jensen Beach, Port Salerno, downtown Stuart near Flagler Avenue, wherever you're stuck. Average response time in Martin County is 25 to 40 minutes.
- We Cut the Key On-Site - Using a mobile key cutting machine, we cut the key blade to your specific Hyundai's lock code. This is precision work. A key cut even slightly off will turn in the ignition but won't start the car, a common issue with cheap online key blanks.
- We Program the Transponder or Smart Key - This is the step the hardware store can't do. We use professional-grade OBD programming software to pair the new key's chip to your Hyundai's ECU. The car won't start without this step, even if the key fits the ignition perfectly.
- We Test Everything Before We Leave - Lock, unlock, start, remote buttons, all of it. We don't pack up until your Hyundai is 100% functional with the new key in hand.
Why Stuart Locksmiths for Your Hyundai Key
We've been doing automotive locksmith work in Stuart for years. Our technicians are licensed under Florida DBPR regulations (Florida Statute 489.501), fully insured, and have programmed keys for hundreds of Hyundai vehicles across Martin County. This isn't a side service. It's core work we do every week.
The humidity here on the Treasure Coast destroys key fobs faster than almost anywhere else in the country. The salt air coming off the St. Lucie River, the heat sitting in a car on a 93-degree July afternoon in Stuart, it degrades the fob housing and the internal circuit board over time. We see more fob failures here than technicians in drier climates do. That local knowledge matters.
We're also significantly faster than the dealer. Hyundai dealers in Port St. Lucie and Stuart typically require you to tow the car in, wait for parts to ship, then schedule a programming appointment. That's often 3 to 7 days without your vehicle. We handle the same job on-site, same day, usually within an hour of your call. If you need general Car Key Replacement services or a Car Lockout Service, we handle those too from the same mobile unit.
Got a Kia with a similar key system? We cover those as well. Our Kia Key Replacement service uses the same OBD programming tools since Hyundai and Kia share the same parent company and similar key platforms across many model years.
We also serve the surrounding areas. If you're in Palm City, Jensen Beach, or down toward Hobe Sound, we come to you. Same pricing, same technicians, same fast response. Need help beyond automotive? Our Transponder Key Programming and Key Fob Programming & Replacement pages cover more detail on those specific services.
Frequently Asked Questions
Can you replace a Hyundai key without the original?
Yes. As long as we have your VIN, we can cut and program a brand new Hyundai key from scratch without any existing key present. We pull the key code from the VIN and cut accordingly. This is standard procedure for lost-all-keys situations.
How long does Hyundai key replacement take in Stuart?
Most Hyundai transponder key replacements take 20 to 35 minutes on-site. Smart key programming for push-to-start models takes a bit longer, typically 35 to 50 minutes. Add 25 to 40 minutes for travel time to your location in Stuart or Martin County.
Will a replacement Hyundai key work for all doors and the ignition?
Yes. When we cut and program a replacement Hyundai key, we program it to the vehicle's full system, which includes the ignition and all door locks. If your Hyundai has a trunk release button on the fob, that gets tested and confirmed as well before we leave.
My Hyundai has push-to-start. Do I still need a physical key cut?
Most Hyundai smart key fobs have a hidden emergency key blade inside the fob housing. It's used if the fob battery dies. We cut that blade as part of the replacement so you're never completely locked out if the fob stops working unexpectedly.
How much does Hyundai key replacement cost compared to the dealership?
Stuart Locksmiths charges $85 to $275 depending on the key type. Hyundai dealers typically charge $175 to $500 for the same service, plus you often have to tow the car in and wait days for an appointment. We come to you and do it same day.
Can you replace a Hyundai key fob that's been damaged by water or heat?
Absolutely. Fob damage from water, heat, or physical impact is one of the most common Hyundai key issues we see in Stuart, largely due to the coastal humidity and summer heat here. We replace the housing and internal components as needed and reprogram the new unit to your vehicle.
Do I need to be at the car when you come?
Yes. Florida law requires the vehicle owner or an authorized person to be present at the vehicle during automotive locksmith services. We'll also verify ownership with your registration or title before we begin programming.
What Hyundai models can you replace keys for?
We cover all common Hyundai models including the Elantra, Sonata, Tucson, Santa Fe, Palisade, Accent, Veloster, Ioniq, Kona, and Genesis. If you're unsure whether your specific model and year is covered, just call us and we'll confirm before dispatch.
Can you program a second Hyundai key so I have a spare?
Yes, and we strongly recommend it. Programming a spare at the same time as the primary replacement is cheaper than coming back for a second visit later, since the car's system is already in programming mode. A spare key typically adds $50 to $100 to the total cost.
What if my Hyundai ignition is also damaged?
If your key issue is related to ignition damage rather than a lost or broken key, we handle that too. Check out our Ignition Repair & Replacement page for details, or just call and describe the issue and we'll diagnose over the phone before sending a technician.
Do you offer emergency Hyundai key replacement at night or on weekends?
Yes. Stuart Locksmiths offers emergency automotive locksmith services outside standard business hours. After-hours calls may have a service fee added, but you won't be left stranded on a Sunday night in a Publix parking lot off Monterey Road. Call (772) 362-5731 any time.
Is it safe to buy a Hyundai key online and have you program it?
It depends. Some aftermarket key blanks work fine. Others are incompatible with Hyundai's immobilizer system and simply won't pair, no matter how good the programming equipment is. If you buy your own key, there's a chance we show up and can't use it, meaning you'd still need to buy one from us. We use vetted key stock to avoid that situation.
