Which Key the Kia Cadenza Actually Uses
Every 2013–2020 Cadenza ships with a Smart Key fob that handles push-button start and remote entry, plus an embedded Emergency Key blade for manual door access when the fob battery dies. Depending on your trim year, the correct fob is matched to one of four FCC IDs — SY5KHFNA04, SY5KHFNA433, TQ8-FO8-4F10, or TQ8-FOB-4F34 — in either a 4- or 5-button layout. We stock all five variants, so there's no waiting on a special order. Learn more about Smart Key fob programming specific to push-to-start vehicles like the Cadenza.
What Happens When All Cadenza Keys Are Lost
Losing every key to a Cadenza is a worst-case scenario the dealer handles slowly and expensively — they'll often require a tow and a multi-day wait. A mobile locksmith can generate a new Smart Key on-site using professional key-cutting equipment and a compatible programmer, without moving the car. Because the Cadenza's immobilizer must recognize the new key's transponder before the engine will start, all programming is done at your location in a single visit. If you're already locked out, our car lockout service gets a technician to you first, then key replacement follows immediately.

Our 24-hour Las Vegas locksmith line dispatches any time, day or night, with firm pricing confirmed before the technician rolls. For the fastest service, have your VIN and proof of ownership ready so we can pull the correct key profile — from the five Cadenza variants we stock — before arriving.

Kia Cadenza key questions
How much does a 2013–2020 Kia Cadenza key replacement cost?
A replacement key for a 2013–2020 Kia Cadenza typically runs around $265 installed by our mobile technician — cut, programmed, and tested at your location in Las Vegas. The firm price is confirmed on-site before any work starts; there is no after-hours surcharge.
Can you make a Kia Cadenza key without the original?
Yes. Even with all keys lost, we can originate a new key for your Kia Cadenza by accessing the immobilizer directly — no dealer tow required. It costs a bit more than copying an existing key, so keeping a spare is the cheapest insurance.
Do you program push-to-start smart keys for the Kia Cadenza?
Yes — we cut and program proximity smart keys (FCC TQ8-FOB-4F34, TQ8-FO8-4F10, SY5KHFNA433, SY5KHFNA04) on-site, so your Cadenza starts and locks normally before we leave.
Which key does my 2013–2020 Kia Cadenza use?
Depending on the exact build, your Cadenza uses one of: Smart Key, Emergency Keys. Match your key to the photos above, or send us the FCC number printed on the back and we'll load the right one.
Can I program a Kia Cadenza Smart Key myself at home?
No — the 2013–2020 Cadenza does not support a DIY self-programming sequence for Smart Keys. A professional programmer is required to write the transponder data to the car's immobilizer system. Attempting to use an unprogrammed key will crank the engine without starting it and can trigger security lockouts.
How do I know which FCC ID my Cadenza key fob needs?
The FCC ID is printed on the back of your existing fob; for Cadenzas it will be one of four: SY5KHFNA04, SY5KHFNA433, TQ8-FO8-4F10, or TQ8-FOB-4F34. If you have no keys left, our technician cross-references your VIN and model year against our five stocked Cadenza variants to select the correct replacement. You don't need to know the FCC ID in advance — just have your VIN ready.
Does the Kia Cadenza Smart Key work at both 315MHz and 433MHz?
The Cadenza's key lineup spans both frequencies depending on the specific variant — some fobs operate at 315MHz and others at 433MHz or 433Mhz. Using the wrong frequency fob will result in a key that won't communicate with the vehicle even after programming. Our mobile locksmiths match frequency and FCC ID to your exact vehicle before cutting and programming.
