2012 Toyota Sienna Smart Key Replacement - Fast, Affordable & Professional
Out in the Woodranch community in Simi Valley, a guy with a 2012 Sienna called me because his last remaining smart key had stopped working. Doors would not unlock from the handle, start button ignored him, sliding doors did nothing. He had two fobs originally but lost one at a campground months back and never replaced it.
He was standing in the driveway holding the dead fob and a grocery bag, looking at the van like it had personally betrayed him.
I pulled up, popped his HYQ14ADR open on the hood, and the CR2032 looked fine voltage-wise. The problem was deeper. The fob's internal board had a hairline crack near one of the battery contact pads. These six-button Sienna fobs take a beating in pockets because the shell is wider than most Toyota keys, and the single-peg housing design does not hold up to years of stress.
I swapped him into a new OEM-spec HYQ14ADR shell, transplanted the board and emergency insert blade, then registered a second replacement fob through the OBD port so he would not be a one-key household again. The Smart Key ECU on the 2012 Sienna (board 89990-08040) accepts up to four registered fobs, and I always push people to carry at least two.
Tested every button on both fobs, both sliding doors, liftgate, handle touch lock and unlock. He just stood there watching the sliding doors cycle open and closed like he had forgotten what they sounded like.
The whole thing took about 40 minutes. A dealer up the road quoted him a multi-day wait and a price that made him wince over the phone. He got it done on his driveway for way less.
