🔧 PRO TIP
The 2017 Mirai runs a smart key system, not a traditional ignition cylinder. There is no blade going into anything -- the fob stays in your pocket or bag and the car starts with a push button. That matters because if start-up fails, the first suspect is the fob battery, which is a CR1632. These cells are thin and light and people forget them entirely until the car starts throwing a key-not-detected warning. Swap the battery, seat it firmly so both contacts are flush, and test every function: door handles, lock button, unlock button, and the start sequence. If range comes back and the dash clears, you just solved it for under two dollars. If the warning stays after a fresh CR1632, that points somewhere else and that is when you call.

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

Cardiff-by-the-Sea is the kind of neighborhood where people park close to the beach and leave their keys in a bag with wet towels, sunscreen, and whatever else. That is exactly the environment that kills a fob battery faster than normal -- heat, humidity, the occasional splash.

A Mirai owner in Cardiff reached out after his car gave him a key-not-detected warning two mornings in a row. Third morning it would not start at all. He had already tried holding the fob closer to the start button, which sometimes works as a backup when the battery is nearly dead, but this time nothing happened.

He figured the fob was cooked. He had called a dealership and was looking at a wait plus the cost of a new smart key with programming, which was not a small number.

I came to him. Popped the fob, pulled the CR1632, and the battery tested low but the contact plate on the negative side had a slight bow to it -- not making full contact even with a fresh cell in there. Straightened the contact, seated a new CR1632, and the dash cleared immediately. Ran through every function on site: both door handles for touch unlock, all four buttons, and the push-button start sequence. Everything worked the way it should.

He did not need a new fob. He needed the right person to actually look at what was happening instead of quoting him a full replacement from the start. He saved a good chunk, and I was in and out before he finished his coffee.

“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 Mirai Mobile Service FAQ

Real costs, no dealer surprises

What is the most affordable way to replace a smart key for my 2017 Mirai?
Call a mobile locksmith first. Going straight to the dealer on a Mirai means scheduling time, possibly leaving the car, and paying for parts, programming, and labor billed separately. With EZ Car Keyz you get everything handled on site in Cardiff-by-the-Sea or wherever the car is sitting -- new fob, programming through the diagnostic port, and a same-day turnaround. No tow, no appointment days out, and the total comes in at a fraction of what the dealer route costs. If you still have one working fob, adding a spare is the least expensive version of this job. Do it before you are stuck with nothing.
How much harder is all-keys-lost on a 2017 Mirai compared to just adding a spare?
Do aftermarket smart keys actually work on the 2017 Mirai, or should I stick with OEM?
My Mirai shows a key warning on the dash but the fob battery is new. What else could cause that?
Can the 2017 Mirai smart key be programmed by a locksmith, or does it have to go to the Toyota dealer?
