🔧 PRO TIP
The 2011 Sienna Smart Key runs Toyota's DST80 encrypted transponder on an 8A (H) chip, not the older G-chip some locksmiths assume. The HYQ14ADR is a 6-button fob with sliding door controls, part number 89904-08010. Here is the thing people miss: during a programming session, every existing working key has to be present. Any fob you leave at home gets wiped from the system. Bring them all or lose them all.

2011 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional

Out in the Sinaloa Lake area in Simi Valley, a woman called me from a hospital parking lot at about 8pm. Her kid had just been discharged and she was ready to get home. She pressed the fob button on her 2011 Toyota Sienna. Nothing. She held it up against the start button for the backup detection procedure. Still nothing.

The dealer was closed for the night.

I got there, opened the door, and connected my IM608 to the OBD-II port. The system identified her smart key setup, the HYQ14ADR 6-button proximity fob with the 8A chip. I popped open the dead fob on the hood. The CR2032 had leaked just enough to corrode the negative battery contact, and the internal antenna board was not transmitting the chip signal at all, even at backup range. The fob was done.

I programmed a new HYQ14ADR, cut the emergency insert blade to match, and tested every function: push-button start, both sliding doors from the fob, lock, unlock, hatch release. Walked the perimeter checking proximity detection at each door handle.

From her phone call to engine running was about 45 minutes. She buckled her kid in and drove home. The dealer would have opened the next morning at best, and she would have been looking at a tow plus a wait. She got her kid home and got the medicine sorted that night instead.

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 also hold NASTF Vehicle Security Professional certification, which gives us authorized access to Toyota's security PIN codes and programming protocols through the same credentialing pipeline that dealerships use. Without NASTF-VSP status, a locksmith cannot pull the codes needed for late-model Toyota smart key registration. If someone shows up to program your Sienna and has never heard of NASTF, that is a red flag.
How do I know I am not calling a scam locksmith?
Will the 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 Sienna keys. Can you still make one from scratch?
