Kia Optima Keys & Fobs
Which key your Optima takes depends on the year. Older Optimas (roughly 2006-2010) use a metal transponder key with a chip in the head that the car has to recognize before it'll start. The 2011-2015 generation runs either a remote-head key (cut blade plus integrated remote buttons) or, on UVO/push-button-start trims, a proximity smart fob you keep in your pocket. The 2016-2020 Optima leans heavily on the proximity smart key for push-to-start cars, with a laser-cut emergency blade hidden inside the fob for the door. Every one of these has to be programmed to your specific car. We pull the immobilizer data off your VIN and sync the new key with our Autel IM508, so the engine actually recognizes it instead of just unlocking the doors.
A really common one on the 2011-2015 and 2016-2020 Optimas is the smart fob "dying" when it's really just the coin battery inside (a CR2032). The car throws a "key not detected" or "smart key system" warning and won't start clean off the button. Before assuming the fob is bad, try the backup start trick: hold the fob right against the start button and press. If that fires it up, you just need a fresh battery. The other frequent one is worn fob buttons or a fob that took one drop too many and cracked the board. If yours is genuinely toast or you're down to your last key, we'll cut and program a replacement on-site so you're not stuck with a single point of failure.

Frequently Asked Questions
Yes. For push-to-start Optimas we read the immobilizer data tied to your VIN and program the proximity smart fob to your car right in your driveway. No dealer trip, and it works for both the door unlock and the push-button start, not just one or the other.
Yes, all-keys-lost is a normal job for us on the Optima. We generate a key off the VIN and immobilizer data, cut the blade (laser-cut or standard depending on year), and program it on-site. It takes longer than adding a spare to an existing key, but you don't need to tow it anywhere.
It depends on the year and whether it's a basic remote-head key or a push-to-start smart fob. Transponder and remote-head keys are cheaper; proximity smart fobs cost more because the part itself is pricier. Across the board we run noticeably under dealer pricing, and we come to you instead of charging for a tow.
A 2013 Optima runs either a remote-head key or, on push-button-start trims, a proximity smart fob. We carry both and program at the car. The 2016-2020 cars lean heavily on the smart key with the laser-cut blade inside. Whatever your year, we pull the immobilizer data by VIN and sync the new key on the spot.
It depends on the year. 2014-2015 Kia Optima: SY5XMFNA04; 2016-2020 Kia Optima: SY5JFFGE04. 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.
