🔧 PRO TIP
The 2017 Sienna smart key runs Toyota's DST-AES encrypted transponder on an H-chip (Texas Instruments TMS37145). During programming, every existing key has to be present. Any fob you leave at home gets wiped from the immobilizer module. So if you have two working HYQ14ADR remotes and only bring one to the appointment, the other one becomes a paperweight. Bring every key you own, even the one you keep in the junk drawer.

2017 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional

Friday night in Simi Valley, close to Sycamore Square. A couple came out from a show and their 2017 Toyota Sienna was completely dead to both fobs. Doors would not respond to the handle touch sensor, push-button start showed "Key Not Detected" on the multi-info display. They were ready to leave the van overnight and deal with it Monday.

They searched "Toyota locksmith" and called me. I was 15 minutes out.

Both HYQ14ADR fobs had drained CR2032 batteries. That is the six-button version with lock, unlock, panic, power sliding doors on both sides, and liftgate. On these third-gen Siennas the fob broadcasts at 314.3 MHz and the car will just ignore it once the battery voltage drops low enough. No graceful degradation, just nothing.

I swapped both CR2032 cells and resynced the remotes using my VVDI Key Tool, which handles the Toyota H-chip transponder data and the remote frequency registration in one pass. Both fobs paired back to the smart key ECU (part number 89990-08060 on these Siennas) on the first cycle. Walked every button: lock, unlock, both sliding doors, liftgate, panic. Tested the push-button start and the handle touch unlock on driver and passenger side.

They drove home that night instead of figuring out a ride and leaving the van in a parking lot all weekend. The whole thing took less time than standing in a dealer service line.

“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.”

“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.”

Toyota Sienna Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Toyota smart key systems?
Yes. EZ Car Keyz holds a California BSIS locksmith license (LCO 6792) and carries full insurance. We are also NASTF Vehicle Security Professional certified, which gives us authorized access to Toyota's security PIN codes and programming protocols through the same credentialing pipeline the dealers use. On the 2017 Sienna, the H-chip DST-AES system will not register a new key without valid security credentials. A locksmith without NASTF access physically cannot complete this job on your van. That is one of the first things worth asking before you book anyone.
How can I tell a legitimate auto locksmith from a scam operation?
Will a replacement smart key work exactly like my original Toyota key?
My Sienna says "Key Not Detected" but the fob battery is new. What is going on?
I lost all my keys. Can you still make a smart key for my 2017 Sienna?
