2006 Acura MDX
Smart Savings on Key Replacement in Ventura County

Q: What do you do to make a new key for my MDX?

I confirm the exact key and remote your 2006 MDX needs from the VIN. That includes the transponder key blank (OEM part like 35113‑SZ3‑A01 or equivalent) and the correct keyless entry remote. On site I cut the blade, program the transponder in the head into the Acura immobilizer with my Smart Pro, then sync the remote buttons to the truck. I test lock, unlock, and starting and make sure the green key light stays off before I leave.

Q: What should I have ready when you arrive for key replacement?

Just the vehicle and a valid photo ID plus proof of ownership like the registration or title. I pull the VIN from the dash to verify which MDX key and remote go with it. If you have an existing remote, bring it so I can confirm button count (three button versus memory variants) and sync all remotes you want working. No need to tow your MDX or sit in a dealer waiting area.

Q: Why is the green key icon blinking and my MDX not starting?

Short answer: the immobilizer is not seeing a valid transponder code from the key you are using. On a 2006 MDX the green key lamp will flash when the immobilizer control unit sees no valid key code. Common causes are a key with no programmed chip, a damaged chip, or interference from other keys near the ignition. After battery disconnect or a dead battery, the immobilizer memory does not erase, but weak contact or damage can make it fail to read. A proper diagnostic and key programming with the right equipment is needed to fix it.

Q: Can I program a replacement remote for my MDX myself?

Short answer: not reliably with just the key and truck. The remote on a 2006 MDX is synced to its security system along with the transponder. While aftermarket instructions sometimes show ignition on off and lock button sequences, Acura’s own guidance points back to dealer or professional scan tool programming for replacing or adding remotes. If you try sequences without all your remotes present, you can overwrite existing ones and end up needing specialized gear to restore them. For a guaranteed result next to your MDX, I bring the right programming tool and confirm each button works before I leave.

🔧 PRO TIP

The 2006 Acura MDX is the last year of the first generation and uses a separate transponder key with a Megamos ID13 chip inside the head (blank 35113-SZ3-A01 or equivalent like HD106-PT/BHD106-PT). The keyless entry remote (FCC ID E4EG8D-444H-A) usually has three buttons (lock, unlock, panic) and a CR2025 cell. A fast blinking green key icon on the dash usually means the immobilizer module is not reading the transponder. Low remote battery often shows up as intermittent lock/unlock response. Know the ignition lock cylinder recall S/B 12-044 replaced by 13-005 for key removal in park.

2006 Acura MDX Transponder Key Replacement - Fast, Affordable & Professional

I got the call from a yoga instructor parked by Fremont Square Shopping Center with her 2006 Acura MDX. She said after the car battery went dead overnight, the green key icon was blinking on the dash and the truck would not start. Second key was missing, and she thought only the dealer could do anything with “that chip thing.”

MDX from this year uses a transponder key with a Megamos ID13 chip and a separate remote with three buttons and a CR2025. I pulled the original head key and showed her the chip is cast inside the head. The immobilizer lamp flashing means the immobilizer control unit and ignition ring antenna are not seeing a valid transponder code.

I pulled the VIN, cut a blank keyed to the lock cylinder (OEM 35113‑SZ3‑A01 equivalent), and put my Smart Pro on it to program the transponder and sync the remote. Her MDX accepted the new key and remote and the green key icon stayed off. She was relieved she did not have to schedule a dealer visit that would have had her week wedged between appointments and waiting in the service bay and saved a good chunk by seeing me right there.

Real costs, no dealer surprises

Can you replace or program my 2006 Acura MDX key on site?▼

Yes. I come to your location in Oxnard, whether you are parked at the Fremont Square Shopping Center or at home. I carry the blanks for the transponder key (Megamos ID13 head blank) and the matching keyless entry remote with FCC ID E4EG8D‑444H‑A, along with professional diagnostic gear that talks to the MDX’s immobilizer. Dealers often want you to bring the vehicle in with a working key or tow it for key programming. I handle this at your car so you keep your time and stay with your truck.
