2018 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional
Over in Mountain Gate Plaza in Simi Valley, a mom had just gotten her kid discharged from a hospital visit. It was around 8pm. Tired child, tired parent, and her 2018 Sienna sitting in the lot doing nothing.
She pressed the fob. Dead. Held it against the start button for the RF backup, where the low-power chip talks to the ring antenna around the button. Still nothing. That backup trick works when the CR2032 is weak, but not when the battery has corroded the contact plate inside the fob housing.
She called me. Every dealer in the area was closed for the night.
I got there, opened the door, and plugged my IM608 into the OBD-II port. The Sienna's smart key ECU, part number 89990-08040 on this generation, came up clean. The immobilizer wasn't confused. It just had nothing to talk to. Her HYQ14ADR fob was the problem, not the car. I set her up with a new fob, programmed it through the diagnostic port, and ran every button: lock, unlock, hatch, panic, and both sliding doors.
From phone call to engine running, about 45 minutes. She buckled her kid in, turned on the AC, and just sat there for a second. Then she drove home.
The dealer would have been a next-morning appointment at the earliest, plus a wait, plus a bill that would have stung. She got home that night instead.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”
