2012 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional

I handle 2012 Chrysler 300 key replacements at your location, start to finish. It's around $288, and that covers the FOBIK blank, the cut, and the programming. Dealer charges closer to $489 for the same job plus you'd need a tow to get there.

A young couple at their apartment complex near Coronado Cays called the Chrysler dealer about replacing their minivan's only FOBIK. They had a baby in a car seat and no time to deal with towing. The dealer quoted $489 and told them to schedule for next week. Their 2012 Chrysler 300 FOBIK had stopped turning in the ignition. I told them I could be there in about 20 minutes.

So I walked over to their car in the apartment lot and used my Y171 Lishi to decode the lock. I read the wafer positions and cut a matching blade right there. Their Smart Key with FCC ID M3N-40821302 was decoded, cut, and programmed in about 35 minutes. I showed them how the FOBIK inserts into the WIN module so they'd recognize the warning signs if it ever started sticking again.

They saved over half versus the dealer and never had to leave the apartment lot. No tow, no week-long wait with a baby and no minivan.

“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.”
