2004 Mitsubishi Montero Sport Transponder Key Replacement - Fast, Affordable & Professional
When a 2004 Mitsubishi Montero Sport key is programmed wrong, the car lets you know. The engine cranks but the immobilizer cuts fuel after two seconds. The remote locks the doors but the transponder won't pass the ID46 challenge. Or the key works for a few days then fails a deeper verification Mitsubishi runs over multiple drive cycles.
A customer at the nail salon in Chula Vista had a key from another locksmith that stopped starting her Montero Sport after about a week. It would crank fine in the morning but by evening the immobilizer would intermittently reject it. She thought the car had an electrical problem, but it didn't.
The other locksmith had used the wrong ID46 variant. Mitsubishi's immobilizer is specific about the chip subtype. I used my VVDI2 to read the bad key's chip and confirmed the mismatch, then programmed a new key with the correct ID46. Her remote, FCC ID , was a 3-button key that I rebuilt and tested thoroughly.
The replacement has been working for months and cost her $108. Dealer would have charged $269. The difference between a key that works and one that dies after a week is the chip inside it.

“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.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
