Hyundai Santa Fe Keys & Fobs
The Santa Fe's key tech depends on the year. Older Santa Fes (mid-2000s up through the early 2010s) use a transponder ignition key, often a remote-head key that combines the cut blade and the lock/unlock buttons in one shell with a chip in the head. From roughly the 2013 redesign forward, most are laser-cut (sidewinder) keys, and higher trims moved to proximity smart fobs for push-button start. The current Santa Fe is almost all proximity smart fob with push-to-start. Every one of these needs the chip or fob married to your specific car's immobilizer, not just cut to fit. We pull the VIN, cut the blade by code on our machine, and program the transponder or proximity fob with our Autel and Xtool gear so it starts the engine and works the remote functions.
A common one on the smart-fob Santa Fes is the fob's coin battery dying. The symptoms look scary, the doors won't respond and push-to-start acts dead, but it's usually just a flat CR2032. Before you panic, there's a mechanical key blade hidden inside the fob to unlock the door, and you can start the car by holding the fob right against the start button. On the older remote-head Santa Fes, the buttons wear out and the plastic shell cracks from years on a keychain, so the remote stops locking the car even though the key still turns. We can re-shell the key or cut and program a fresh one rather than replace the whole expensive unit.
Hyundai Santa Fe 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 Santa Fe takes before the van rolls out.
| Years | Key type | FCC ID |
|---|---|---|
| 2013-2018 | Proximity smart fob | SY5DMFNA04 |
| 2021-2023 | Proximity smart fob (by trim) | TQ8-FOB-4F26, TQ8-FOB-4F27, TQ8-FOB-4F28 |
Spare key with a working key in hand: from $75. Full replacement, no key at all: from $189. Smart and proximity fobs price above basic chip keys; the exact flat number comes with your VIN on the call.
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.

Frequently Asked Questions
Yes. An all-keys-lost situation on a push-to-start Santa Fe takes longer than just adding a spare because we have to access the immobilizer and program the proximity fob from scratch, but we do it on-site by VIN. Bring or have your ID and proof you own the car ready.
There's a metal emergency blade tucked inside the smart fob for unlocking the door if the battery dies or the car has no power. We cut that blade to your VIN so it actually turns your door lock, and we program the proximity side so the fob starts the engine. You get both working.
It depends on the year and whether it's a transponder key or a proximity smart fob, since the smart fobs cost more in parts. As a range, most Santa Fe jobs land in the low-to-mid hundreds, and we're typically well under dealer pricing with no tow bill since we come to you.
We do. The current Santa Fe is push-to-start, so a 2023 takes a proximity smart fob programmed to the immobilizer at the car, plus a laser-cut emergency blade matched to your doors. The older remote-head and transponder years going back to the mid-2000s are covered the same way. Any year at all, just have the VIN ready.
It depends on the year. 2013-2018 Hyundai Santa Fe: SY5DMFNA04; 2021-2023 Hyundai Santa Fe: TQ8-FOB-4F26 or TQ8-FOB-4F27 or TQ8-FOB-4F28. 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.
