2021 Mitsubishi Outlander Sport Smart Key Replacement - Fast, Affordable & Professional
I got a call from a resident at Coronado Shores, one of the condo towers right on the water, who had already paid another locksmith to cut and program a replacement smart key for his 2021 Outlander Sport. The fob locked and unlocked the doors fine. But every time he tried to start the car, it would crank, catch for about two seconds, and then shut off. The other locksmith told him the immobilizer module was faulty and walked away.
I have seen that exact symptom before and it almost never means the module is bad. The engine cranking and then immediately dying is the immobilizer doing exactly what it is supposed to do when a key is not fully committed to memory. It recognizes something, starts the process, then rejects it. The key was written partially. The confirmation step that permanently registers it was either skipped or timed out.
I connected through the OBD port and pulled up the key registration data. The previous attempt was in there, incomplete. I cleared it out completely, ran the full registration sequence with the correct timing, and waited for the system to confirm permanent storage before I disconnected anything. Then I tested the start three times back to back, which is the only way I actually trust a result on a job like this.
He mentioned what the dealer had quoted him when he first lost the original key. What he ended up paying me was a fraction of that, even accounting for what he had already lost to the first locksmith. That part I could not undo. But the car started, and that part I could.

“Quick, affordable, and professional service. Marco made a new key for my motorcycle after I lost it and had me back on the road fast. Clean work, great price, and super friendly.”
“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
