What Happened
The Problem
A North Las Vegas resident in the Aliante area lost his 2021 Kia Sorento key fob. He still had a physical key to enter and start the car, but the remote functions were gone — no remote lock/unlock, no panic, no remote start. He called us to program a new fob on-site.
What We Did
Our technician arrived in Aliante in 24 minutes. The 2021 Sorento uses a Kia/Hyundai shared platform — we confirmed the fob part number (TQ8-FOB-4F27), checked the frequency (433MHz), and connected the Autel MaxiIM IM608 to the OBD-II port. The programming sequence ran without issues. All four fob buttons — lock, unlock, trunk, remote start — were tested and confirmed working.
