Question 1

I lost all my keys to a 2003 Mitsubishi Galant. Can you still make one?

Accepted Answer

Yes, all-keys-lost on the 2003 Galant is a job we handle on site. The process involves cutting a new key blade to the vehicle, clearing any existing key data from the immobilizer, and running a clean registration sequence. Because there's no working key to reference, the procedure takes a bit longer than a standard add-a-key, but it doesn't require a tow and it doesn't require the dealer. Expect around 30 to 45 minutes once I'm on site. Dealers will typically tell you to tow the car in and add scheduling time on top of that. We come to you in Encinitas and get it done where the car sits.

Question 2

Do I have to tow my 2003 Galant to the dealer if I have no keys?

Accepted Answer

No. The 2003 Galant's key system is within range of mobile programming equipment. You don't need a tow. Dealers will sometimes push towing as the only path because it's easier for their workflow, but a mobile locksmith with the right OBD-based tools can handle all-keys-lost right in your driveway or on the street. The only time towing becomes the real answer is when there's an underlying electrical fault that goes beyond the key system itself, and that's rare. I'll tell you upfront if something on arrival points in that direction.

Question 3

How long does a key replacement take on the 2003 Galant?

Accepted Answer

A standard add-a-key where you have one working key usually runs 20 to 30 minutes. All-keys-lost takes a bit longer, closer to 30 to 45 minutes, because the immobilizer reset and full registration sequence adds steps beyond just pairing a second key. The programming step itself goes fast once connected. Most of the time is setup, blade verification, and confirming the key is permanently stored before I pack up and leave.

Question 4

My 2003 Galant starts and immediately stalls. Could that be a key or immobilizer problem?

Accepted Answer

That specific symptom, engine fires and dies within two seconds, is one of the more recognizable signs that the transponder in the key isn't being recognized correctly by the immobilizer. On the 2003 Galant, it shows up two ways: either the key was never properly registered to begin with, or a previous programming attempt didn't complete the full confirmation cycle and left partial data in the system.

It can also show up when someone buys a replacement key online and tries to use it without getting it programmed, or when a key gets cloned incorrectly.

Worth noting: if the engine cranks but won't fire at all, that's a different path and could point to something outside the key system entirely. But start-and-immediately-stall on a car that was running fine the day before, with the original key, points toward the transponder and the immobilizer communication. That's diagnosable and fixable on site.

Question 5

Can I buy a replacement transponder key online and just have it cut, without programming?

Accepted Answer

Cutting alone won't do it. The 2003 Galant has an immobilizer that reads the transponder chip inside the key head. If the chip isn't registered to the vehicle, the car cranks and stalls, or won't run at all past those first couple seconds. You can buy an uncut replacement key shell, have the blade cut to your vehicle, and then have it programmed, but the programming step is not optional and can't be done without the right equipment. If someone sold you a key and just cut it without programming, that's why it isn't working.
