Hyundai Sonata key fob replacement in McKinney, Plano, Frisco and nearby cities starts with knowing which key your year uses. Both 2011-2014 and 2015-2017 Sonatas with push-button start run a proximity smart fob. Our Apex Locksmith Pros technician cuts and programs your Sonata key on-site by VIN, wherever the vehicle is parked, and pairs it to the immobilizer so it starts the engine. A flat total is given on the phone before dispatch; no call-out fee applies.

What Key Does the Hyundai Sonata Use?
The Sonata's key changed a lot over the years, so we match it to your exact model and VIN. Older Sonatas (roughly 2006 through 2014) use a transponder chip key, and the newer ones in that range take a remote-head key that combines the cut blade and the lock/unlock buttons in one unit. From about 2011 up, push-to-start trims use a proximity smart fob (push-button start, no blade in the ignition) plus a hidden emergency key blade tucked inside the fob. The 2015-and-up cars moved to a laser-cut (sidewinder) blade on the keyed trims, which needs a higher-end key machine, not the cheap hardware-store cutter. Every one of these has to be cut to your VIN and then programmed to the car's immobilizer with a scan tool so the engine will start. Adding a smart fob also means pairing it to the body control module. We carry the blanks and run an Autel IM508 so we handle the cutting and the programming in one stop.
The most common Sonata call
A really common one on the 2015-2019 Sonata is the proximity fob that stops working from across the lot, or the door won't recognize it until you press the handle button two or three times. Most of the time that's just the CR2032 coin battery inside the fob going flat, and a fresh one brings it right back. If a new battery doesn't fix it, the fob's circuit board or its internal antenna may be worn out, especially if it's been dropped or ridden around in a pocket for years. We test the fob on the spot and tell you straight whether it needs a battery or a full replacement and reprogram.
Hyundai Sonata Key Fob FCC IDs
Flip your fob over: the FCC ID is printed on the back of the case. Find it below, or just read it to our dispatcher. It tells us the exact remote your Hyundai Sonata takes before the van rolls out.
| Years | Key type | FCC ID |
|---|---|---|
| 2011-2014 | Proximity smart fob | SY5HMFNA04 |
| 2015-2017 | Proximity smart fob | TQ8-FOB-4F07 |
Trim and market can change the fob, and several IDs often fit one model year. We confirm the exact part by VIN on every job, so a mismatched guess never reaches your driveway.

What Do Hyundai Sonata Owners Ask?
Straight answers for Hyundai Sonata owners in McKinney and nearby cities: which key your car uses, what to have ready and how on-site programming works.
Yes. An all-keys-lost Sonata is one of our regular calls. We pull the key code from your VIN, cut a fresh blade, and program it to the car's immobilizer on-site, no working key needed to start. All-keys-lost takes longer than a spare since we have to reset the system, but we still knock it out in one visit, same day.
It has to be programmed. A fob you buy online is a blank until it's paired to your specific car's body control module and immobilizer, so an un-programmed one won't lock, unlock, or start anything. We can program a fob you already bought, or bring our own, then cut the hidden emergency blade inside it to your VIN so the whole thing works.
It depends on which key your year takes. A basic transponder or remote-head key runs less than a push-to-start proximity fob, which has more electronics inside. Across the board we come in under dealer pricing, and you don't pay to tow the car in since we cut and program it wherever you're parked. We give you the exact number for your Sonata before we start any work.
We do. A 2013 Sonata takes either a remote-head transponder key or, on push-to-start trims, a proximity smart fob with the emergency blade inside, both programmed on-site. The 2015-and-up sidewinder blades need the laser machine we carry on the van. Any Sonata year; the VIN decides the blank and the cut.
It depends on the year. 2011-2014 Hyundai Sonata: SY5HMFNA04; 2015-2017 Hyundai Sonata: TQ8-FOB-4F07. The ID is printed on the back of your fob case. Trim and market can change it, so we confirm the exact part by VIN before the van rolls out.
