Emergency 2016 Toyota Mirai key fob made from scratch by EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2016 Mirai runs Toyota's Smart Key system with the same Texas Instruments DST-AES 128-bit transponder used across the Toyota/Lexus lineup in that era. FCC ID HYQ14FBA, part number 89904-30A30, CR1632 battery. The keyway is TOY43, which is shared with a bunch of Toyotas and Lexus models from that period. If the dash throws "Key not detected" or the blue indicator on the start button won't pulse, swap the CR1632 first. That battery is thinner than the CR2032 people grab by mistake, and a wrong cell will wedge the housing and bend the contacts.

2016 Toyota Mirai Smart Key Replacement - Fast, Affordable & Professional

A guy out at Rincon Beach Park in Ventura lost his only Mirai key somewhere between the sand and the parking area. Looked for close to an hour, checked with people nearby, retraced his steps, nothing. His 2016 Mirai was just sitting in the lot.

He called two dealers before he called me. One quoted him a multi-day wait plus a tow. The other said they would need to order the fob and he should plan on leaving the car.

I started with my TOY43 Lishi on the driver door. The Mirai uses the same TOY43 keyway as most Toyotas of that generation, so the Lishi picks and decodes each wafer position inside the cylinder. That gave me the exact bitting for the emergency insert blade without needing the original.

Then OBD. The Mirai's immobilizer is the same Toyota Smart Key architecture running DST-AES on the 8A transponder chip. I cleared the old key registration through the diagnostic port and wrote the new HYQ14FBA proximity fob into the system. Four buttons: lock, unlock, trunk, panic.

He sat on a bench watching the ocean while I worked. When I handed him the fob and he hit the start button and the dash lit up, he just kind of nodded. Like he was relieved but also slightly annoyed it had taken longer to search the beach than it took me to build a key from nothing.

About 50 minutes, lock decode to engine running. A fraction of what the dealer wanted, and no tow truck involved.

Toyota Mirai Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2016 Mirai smart key?
Call a mobile locksmith before you call the dealer. The dealer route on a Mirai means paying separately for the fob (89904-30A30), the emergency blade cut, programming time, and often a diagnostic fee on top of that. Then you wait for the part to ship, because most Toyota dealers do not stock Mirai fobs. With me, you get the HYQ14FBA cut, programmed, and working at your car in one visit. No tow, no appointment days out, and it costs way less than the dealer total.
How much more does an all-keys-lost job cost compared to adding a spare?
Will an aftermarket smart key fob work on my 2016 Mirai?
My Mirai shows "Key not detected" but the fob battery is new. What is wrong?
Can I start the Mirai if the smart key fob battery is completely dead?
