🔧 PRO TIP
The 2021 Sienna went full hybrid that year, every single trim. The smart key fob takes a CR2450, which is a bigger cell than most Toyota fobs use. That larger battery is good for longevity, but owners sometimes swap in the wrong size because they grabbed what the parts store handed them. A CR2032 will sit in there and make contact, but the voltage drop causes weird behavior: the sliding door buttons respond slowly, touch-to-unlock on the handles gets flaky, and the dash throws a key-not-detected warning even when the fob is right there. Check the battery size before you assume the fob or the antenna is the problem.

2021 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional

I was parked on Upper State Street when the call came in. Guy had a 2021 Sienna, fully loaded, and he was standing in the parking lot of a shop off the same stretch. He'd already been burned once.

He'd searched for a locksmith a few weeks earlier when he locked himself out. Clicked the first sponsored result, got a price on the phone, and watched it triple the moment the tech showed up. That guy had no marked vehicle, handed him a hand-scrawled receipt, and gave him a fob that only half-worked. The sliding door buttons were dead. Engine start was intermittent. He'd been living with it because he didn't want to deal with another stranger at his car.

He found me through Google Guaranteed, saw the BSIS license number listed, and called. California's Bureau of Security and Investigative Services licenses locksmiths in this state. Background check, insurance, registered business. He asked for my license number before I drove over. I gave it to him, told him to look it up, and started heading his way.

When I got there I put the fob on the hood and we went through it together. The battery was the wrong size for the application. The previous guy had used whatever he had in his bag, and it had been making intermittent contact ever since. Swapped in the correct CR2450, reseated everything cleanly, then ran through all six buttons, tested both sliding door handles for touch unlock, and confirmed clean start behavior on the push-button.

Everything worked the way it was supposed to. He asked what the dealer would have charged to sort this out. I told him to call and find out, but that I was already done. He laughed.

Toyota Sienna Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my 2021 Sienna?
Call a mobile locksmith, not the dealer. Toyota dealer all-keys-lost quotes on the Sienna are not cheap, and they often can't get to it same-day, which means you're either towing the van or waiting. A mobile locksmith comes to you in Santa Barbara, does the key reset through the diagnostic port, programs the new fob, cuts the emergency blade insert, and tests everything before leaving. No tow, no overnight, no service department markup. The 2021 Sienna also requires the old unregistered fobs to be wiped from the system during that process, so only the new key has start authority when we're done. If you're on Upper State Street or anywhere nearby, that's a one-trip job.
Can you delete lost or stolen fobs from my Sienna so they can't start it anymore?
Does my 2021 Sienna smart key have an emergency blade inside it?
My 2021 Sienna shows a key-not-detected warning but the fob is right in my hand. What's going on?
I bought a replacement fob online for my 2021 Sienna. Can I program it myself?
