2002 Acura MDX
Wallet-Friendly Key Replacement in Ventura County

Q: How fast can you get to me in the Saviers Road business district?

It depends on the call load when you ring me, but I give you a real arrival window on the phone. I work mobile, so I am already set up to handle a 2002 MDX on site, whether it is a no-start with the immobilizer light blinking or just a dead remote. Dealer visits usually mean scheduling, proof of ownership checks, and waiting around while they cut a key by VIN and hook up their scan tool. I come to your parking spot and do it there.

Q: Can you make a key for my 2002 MDX today?

In most cases, yes. I stock the HD106-PT style transponder keys used on the first-generation MDX, along with the common E4EG8D-444H-A remotes and CR2025 batteries. As long as you have proof of ownership and the vehicle is accessible in the Saviers Road business district, I can usually cut, program, and test everything the same day. If it is an all-keys-lost situation or there is an immobilizer fault, it can take a bit longer.

Q: My MDX cranks but will not start and the green key light flashes. Why?

Yes. That flashing green key icon is the immobilizer telling you it does not recognize the transponder. On the 2001 to 2002 MDX, Acura used a Type 2 immobilizer system that will disable the fuel system if the key code is wrong or unreadable. Owners often report this after a battery drain or after the key gets wet or damaged. Some forum threads describe a crank with no fuel pump prime and a blinking indicator. If a spare key does the same thing, the issue can be the immobilizer receiver ring around the ignition, part number 39730-S3V-A01, or related wiring.

Q: Which remote does my 2002 MDX need, and why will mine not program?

Short answer: matching the FCC ID is not always enough. Most 2002 MDX remotes share FCC ID E4EG8D-444H-A and IC G8D-444H-A, but there are different part numbers. Non-memory trucks use 72147-S3V-A02. Models with driver seat memory use transmitters like 72147-S3V-A13 or -A23 labeled for Memory 1 or Memory 2. If you buy the wrong version, the onboard programming sequence will not sync it correctly with the memory system. I check the door panel for memory buttons and match the transmitter before programming.

🔧 PRO TIP

2002 MDX is a turn-key setup with a Type 2 immobilizer. If it cranks and the green key light starts blinking, the car is not reading the transponder. Acura even warns that another immobilizer key or a big metal keychain near the ignition can mess with the read. Try starting with only the MDX key on a plain plastic ring. These keys have no battery, so a fresh battery never fixes a no-start.

2002 Acura MDX Transponder Key Replacement - Fast, Affordable & Professional

In Oxnard, over in the Saviers Road business district, a 2002 MDX owner walked out to his SUV and hit LOCK out of habit. Nothing.

He had one working black master key, but his remote had died and he bought a replacement online that “matched the FCC ID.” He kept doing the ignition-cycle dance he saw on a video and it still would not take.

First thing I did was flip his old remote over. It was stamped as a Memory transmitter, part number 72147-S3V-A23. His new one was a no-memory 72147-S3V-A02. Same FCC ID E4EG8D-444H-A, different job.

While he watched, I cut a fresh HD106-PT style transponder key with the Megamos 13 chip, what a lot of locksmith catalogs call T5, and registered it so he had a clean spare that starts the truck even if the old key takes a beating.

Then I programmed the correct Memory remote, tested lock, unlock, and panic, and made sure it behaved with the seat memory buttons like it should.

He just nodded, pocketed the new remote, and went right back to work. Dealer route would have meant paperwork, waiting, and the MDX sitting somewhere else for a while.

“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.”

How long does a 2002 Acura MDX key replacement take?▼

Most 2002 MDX key jobs are under an hour once I am at the vehicle. If you still have a working master or valet key, I can add a new HD106-PT or BHD106-PT transponder and cut it to match. These use a Megamos 13, also called ID13 or T5, chip. All-keys-lost takes longer because I have to originate the cut and complete immobilizer registration from scratch. The keyless remote, part numbers like 72147-S3V-A02 or -A23, is a separate step after the engine-start key is sorted.
