🔧 PRO TIP
The 2014 Sienna Smart Key runs Toyota's DST80 crypto on an H-chip (Texas Instruments TMS37126). During any programming session, every existing key has to be present and re-registered, because the system wipes all stored fob IDs and starts fresh. If you leave a working spare at home, that spare is dead when you get back. Bring every fob you own, including the valet key if you have one. Also, the HYQ14ADR uses a CR2032, but a weak one throws "Key not detected" on the dash before the battery fully dies, so people think the immobilizer failed when it is just voltage drop.

2014 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional

A farm worker called me at 5:30 in the morning from the supply store lot near Simi Valley Town Center. His shift started at six, the crew was already loading, and his 2014 Sienna would not wake up. Push the start button, nothing. Dash just showed "Key not detected" and sat there.

I made it to him in about 25 minutes.

First thing, I used my TOY43 Lishi to decode and open the driver door. Quick, no damage, no slim jim drama. Inside, I popped the back off his HYQ14ADR fob and the CR2032 was swollen enough to notice. That alone can tank the signal strength so the car's cabin receiver on the Smart Key ECU (board 89990-08040) never sees a valid ping.

Swapped the battery, connected through OBD, and ran a re-registration cycle. The H-chip handshake confirmed on the first pass. Tested all six buttons: lock, unlock, panic, both power sliding doors, and the rear hatch. Then verified push-to-start from every seating position, because these vans have three interior antennas and I have seen one go lazy before.

Twenty minutes, hands-on. He drove out of that lot and made it to the field before the crew finished loading. I left a spare CR2032 in his glovebox so he would not get stuck like that again.

The dealer quoted him a tow plus a full-day wait. He did not need any of that.

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 is licensed through the California Bureau of Security and Investigative Services (BSIS License LCO 6792) and carries full insurance. We are also NASTF Vehicle Security Professional certified, which gives us authorized access to Toyota's security PINs and programming protocols, the same credentialing pipeline dealers use. Without NASTF-VSP status, a locksmith cannot pull the seed codes needed for H-chip registration on a 2014 Sienna. Not every shop has this, and if they do not, they cannot program your key at all.
How can I tell if a locksmith is legit before they show up?
Will the replacement smart key work exactly like my original?
My Sienna shows "Key not detected" but the fob battery is new. What is going on?
Can I use the emergency key blade if the smart key fob completely dies?
