🔧 PRO TIP
The 2003 Lancer uses a Texas Instruments Texas Crypto transponder chip, specifically a Philips/NXP ID46 (T14) type in most trims. The immobilizer ECU lives inside the ETACS (Electronic Total Automobile Control System) module, not a standalone unit. If you get a new key cut but skip programming, the engine cranks and dies within two seconds. That's the immobilizer doing its job. The key blade is a standard MIT9 or MIT3 profile, and the transponder glass capsule sits in the key head, no battery involved.

2003 Mitsubishi Lancer Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy in Upper Village, Montecito, standing next to a 2003 Lancer with the trunk open and a broken key in his hand. The blade had snapped right at the plastic head where it meets the housing. The transponder chip was still in the remaining half of the key head, which was good news, but the blade piece was stuck in the ignition cylinder.

He had already tried tweezers. Then needle-nose pliers. Then a magnet. The broken bit just spun in place.

I extracted the blade fragment from the ignition first. These MIT3 cylinders are forgiving if you go slow. Once it was out, I had a clean original to decode from, just in two pieces. Cut a new MIT9 blade on site, then moved to the transponder side. The 2003 Lancer runs a Mitsubishi immobilizer system with an ID46 crypto chip. I cloned the working chip from his broken key head into a fresh T14 transponder using my programmer. No need to touch the ETACS module when you have a working chip to clone from.

Key went in, turned, engine fired. He just stood there holding the two broken halves like he forgot he could put them down.

The whole thing took about 25 minutes on his driveway. A dealer would have wanted the car towed in, a new key ordered, and probably a week of waiting for the part.

“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”

“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”

Mitsubishi Lancer Mobile Service FAQ

Real costs, no dealer surprises

How much does a replacement transponder key cost for a 2003 Mitsubishi Lancer?
Call us for the exact number. What I can tell you is it runs way less than the dealer route. Mitsubishi dealers typically charge separately for the key blank (often listed under part number MR587983 or a variant for the Lancer generation), then blade cutting, then programming labor at shop rate. That adds up fast, and most dealers want the car on-site to do it. With us, one price covers the transponder key, cutting the MIT9/MIT3 blade, programming the ID46 chip to your ETACS module, and testing, all at your location in Montecito.
Is a mobile locksmith cheaper than the Mitsubishi dealer for key replacement?
Does your price include both cutting and programming the transponder?
I lost all my keys for the 2003 Lancer. Can you still make one?
My 2003 Lancer cranks but won't start and the immobilizer light is blinking. What does that mean?
