2012 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional
A family over near The Oaks Mall Area lost their only fob somewhere between a shopping run and the parking lot. By the time they were sure it was gone, they had tired kids, a locked 2012 Chrysler 300, and no spare. They called me instead of waiting for a tow.
I got there in under 30 minutes. The 300 is a full-size sedan, so there's no sliding door or liftgate to worry about as an entry point. I picked the door lock to get them in, then decoded the wafer positions from the lock cylinder and cut a fresh blade to match. From there I connected through the OBD port, extracted the security PIN from the immobilizer module, and ran the all-keys-lost sequence. That process clears every previously registered key from the vehicle's memory and enrolls the new fob as the primary. The new key started the car on the first try. I cut a second one while I was there so they'd never be in this spot again.
The whole job ran about 45 minutes, start to finish. The dealer route would have meant a tow, an appointment days out, and a bill several times what I charged. They loaded the kids and left with two working keys.
The part that sticks with me: they had owned that car for years on a single key. A lot of Chrysler owners do. It works fine right up until it doesn't.

“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.”
“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.”
