2012 Acura MDX Remote Flip Key Replacement - Fast, Affordable & Professional
Early morning call in Oxnard Shores. A contractor had his 2012 Acura MDX loaded up with tools and materials, ready to get to a job site.
It would fire for a second, then shut right off. Green key icon blinking on the dash. He had already swapped the CR1616 in his flip key, part number 35111-STX-329, thinking that was the fix. Remote worked fine. Doors locked and unlocked. Engine did not stay running.
On these YD2 MDXs, the transponder is a Philips ID46 chip buried in the head of the flip key. Battery has nothing to do with starting. If it cranks and dies with that immobilizer light flashing, the system is rejecting the chip signal.
I verified the HON66 keyway, scoped the ignition cylinder for wear, then connected to the OBD-II port with my Autel IM608. Immobilizer data showed irregular communication logs. Honda/Acura put out TSB 09-034 covering 2007 through 2013 models where intermittent immobilizer faults cause post-crank stalling tied to transponder read failures. His key had taken a solid hit at some point and the PCF7936 chip response was inconsistent.
I cut and programmed a fresh N5F0602A1A flip key, erased the damaged one from the system, and ran start cycles until I was satisfied. No more flashing green key. No stall.
He just nodded, turned it off, started it again himself, and drove off to work like nothing happened.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”
