2016 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional
A woman at the Madera Road shopping area in Simi Valley had her stuff together before I even pulled up. She had texted me the VIN from her registration the night before. That one detail let me confirm her 2016 Sienna used the HYQ14ADR with the 8A chip and the six-button layout, including the two sliding door buttons that make this fob different from the Camry or Highlander version.
I had the correct blank programmed and the emergency insert key cut in the van on the drive over.
She met me in the parking lot holding her working fob and a spare that had stopped responding about a week earlier. Turned out the spare had a dead CR2032 and corroded contacts, but the immobilizer still recognized its chip ID. So instead of a full reprogram, I cleaned the battery terminals, dropped in a fresh CR2032, and confirmed the smart computer on the dash picked it up at all four doors plus the liftgate.
Then I cloned her working key onto a brand new third fob using the VVDI2. Read the 8A chip data, wrote it to the new blank, and registered it through the OBD port. The immobilizer's seed-key handshake confirmed on the first cycle.
From parking to handing her a tested spare: 17 minutes. She said the dealer had quoted her two weeks out for an appointment and a number that made her start Googling locksmiths. I get that call a lot with these third-gen Siennas.

“Quick, affordable, and professional service. Marco made a new key for my motorcycle after I lost it and had me back on the road fast. Clean work, great price, and super friendly.”
“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“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.”
