🔧 PRO TIP
2011 Sienna smart key setup has one rule that bites people constantly: all existing fobs have to be present at the programming session. Any key that isn't physically there gets wiped from the vehicle's memory. Doesn't matter if it's your spouse's key sitting on the counter at home or a spare you tossed in a drawer. If it's not in your hand when I run the procedure, it's dead after. Bring every single fob you own to the appointment. No exceptions. Also worth knowing: the 6-button fob on this generation runs a CR2032. Before you assume the fob is dead, pull that battery and check the contacts inside. The 2011 vintage is old enough now that corrosion on those contact strips is a real thing, and a corroded contact will kill a brand-new battery just as fast as a worn-out one.

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

I got the call from a parking lot off the 118 at 8 in the evening. A woman up in Big Sky, Simi Valley had just gotten her kid discharged from a children's hospital and was standing next to her 2011 Sienna with a fob that was doing nothing.

She had already tried holding the fob flat against the start button, which is the backup procedure Toyota builds in for exactly this situation. Nothing happened. The car just sat there. She had a tired, sick child in her arms and zero interest in troubleshooting. She needed to go home.

The dealer was closed.

When I got there I popped the fob open on the hood of the car. The CR2032 contacts had corrosion on them, the kind that builds up slowly over years until one day the key just quits mid-parking lot. The backup start procedure needs the antenna to read through the fob body, and corroded contacts killed that signal completely. New fob, programmed through the OBD port, every button tested, emergency insert key verified in the door lock. The whole thing took 45 minutes from her call to the engine running.

She didn't say much when she drove away. She didn't need to. She had her kid in the back seat and she was heading home. That's the job.

Toyota Sienna Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Toyota vehicles in California?
Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services and carries full liability insurance. We hold NASTF Vehicle Security Professional certification, which gives us authorized access to the security data and programming protocols required for vehicles like the 2011 Sienna. That credentialing matters because Toyota's smart key system requires manufacturer-level security access to register a new fob. Not every locksmith carries it, and without it, the programming simply cannot be completed correctly. You can verify the BSIS license and the NASTF credential before you call.
How do I know EZ Car Keyz is legitimate and not a bait-and-switch locksmith?
Will the replacement fob work exactly like my original factory key?
My 2011 Sienna starts fine but the sliding door buttons on the fob stopped working. Is the whole fob bad?
I bought a replacement fob online for my 2011 Sienna. Can I program it myself?
