🔧 PRO TIP
The 2012 Civic runs a 9th-gen Honda immobilizer with an ID46 (Hitag2) transponder chip and a high-security side-milled blade (profile HON66). The remote head key is FCC ID N5F-S0084A, part number 35111-SVA-306, CR1616 battery. If the green immobilizer light on the dash blinks and the engine cranks but won't fire, that's the transponder not authenticating, not a starter or fuel issue. Swap the CR1616 first, but know that battery only powers the remote buttons, not the chip.

2012 Honda Civic Remote Head Key Replacement - Fast, Affordable & Professional

A tattoo artist over by Community Memorial Hospital in Ventura flagged me down in his shop's lot. He had a 2012 Honda Civic and one question: would the key be as good as what the dealer sells. Not a backup key. His daily driver key.

Fair question.

OEM Honda remote head keys come with the logo stamped on the housing, the factory part number 35111-SVA-306 on the box, and a fat brand markup stapled to the receipt. The aftermarket blanks I carry use the same HON66 side-milled blade profile, same ID46 Hitag2 transponder, same four-button layout on the N5F-S0084A circuit board. In daily use the functional difference is zero if the blank is good quality.

I cut the blade on my Triton machine right there on his lot, programmed the transponder through the OBD-II port, and synced all four remote buttons. Lock, unlock, trunk, panic. Then I tested the immobilizer cycle: key in, green key light on dash goes solid, engine fires. Pulled it out, tried his old key, tried the new one again. Both registered and both starting clean.

He turned the key over in his hand looking for the catch. No Honda logo on the back. That was the only difference. He pocketed it and went back inside.

Whole thing took maybe 25 minutes. A dealer would have quoted him a week's wait for the part and a shop visit on top of it, for a good chunk more than what I charged him in that parking lot.

“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Honda Civic Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2012 Honda Civic. Can you still make one on site?
Yep. All-keys-lost on the 9th-gen Civic is a standard mobile job. I connect through the OBD-II port, run the Honda immobilizer reset to wipe the old key codes, then register fresh ID46 transponders. The blade gets decoded and cut to your car's locks right there. Old missing keys get erased from the system so nobody can walk up and start it. The whole thing runs about 30 to 45 minutes depending on how many new keys you want programmed. No tow, no dealer, no waiting room.
Do I really need to tow my Civic to the dealer if I have no working key?
How long does an all-keys-lost replacement take on a 2012 Civic?
My 2012 Civic's green key light blinks but the engine won't start. Is it the key or the car?
Can I program a new transponder key to my 2012 Civic myself using the ignition?
