2017 Toyota Mirai Smart Key Replacement - Fast, Affordable & Professional
When a 2017 Toyota Mirai key is done wrong, the car fights it. The engine cranks but cuts after two seconds. The remote locks but will not unlock. The push-to-start works for a few days then randomly shows "key not detected." Or the immobilizer silently rejects the key after a couple of drive cycles and you are stranded with no warning.
A woman at the laundromat in Encinitas had a key from another locksmith that started failing after about 10 days. Her Mirai would start fine in the morning but by evening the push-to-start would not respond. She thought the car had a wiring issue.
The other locksmith had used the wrong chip generation. Toyota's immobilizer is specific about which chip type it accepts. A 4D chip in a car that expects a G-chip will sometimes pass the initial registration but fail the deeper verification Toyota runs over multiple start cycles. I used my VVDI2 to read the bad key's chip and confirmed it was wrong. I programmed a new fob with the correct chip matched to her FCC ID HYQ14FBA, and replaced the weak CR1632 battery that was adding to the detection failures.
The replacement has been working for months and cost her $232. The dealer would have charged $414. The difference between a key that works and one that works for a week is the chip. I match the correct generation for every Toyota because redoing a job is bad for everyone.

“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.”
“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”
