Emergency 2012 Chrysler 300 key fob made from scratch by EZ Car Keyz Thousand Oaks CA
🔧 PRO TIP
The 2012 Chrysler 300 runs the Fobik system, not a traditional smart key with a proximity slot. FCC ID M3N-40821302, part number 5026676AH, five buttons including remote start. The immobilizer talks through the WIN (Wireless Ignition Node) module, which replaced the older SKIM starting in 2008. A weak CR2032 won't just kill range. It can trigger "Key Not Found" or "Key Fob Not Detected" on the EVIC and leave you locked out completely. Swap the battery first, always.

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

A family near California Lutheran University in Thousand Oaks lost their only Fobik at one of those overflow parking areas after a long day out. Searched everywhere, checked lost and found twice, nothing. Their 2012 Chrysler 300 was just sitting there with four tired kids and no way in.

I told them about 30 minutes.

Started with my Y171 Lishi to pick the door lock and decode every wafer position. The 300 uses a standard Y171 keyway on the driver door cylinder, so I had the cut data before I even touched my key machine. Cut a fresh emergency blade to match right there on the hood.

Then the real work. Connected through OBD-II, pulled the four-digit PIN from the WIN module, and ran the all-keys-lost procedure. That sequence wipes every previously registered Fobik from the car's memory and writes the new one as primary. Their M3N-40821302 started the 300 on the first press. I programmed a second Fobik while I was in the system, because adding a spare while you're already connected takes almost no extra time compared to doing it as a separate visit later.

The whole job ran about 45 minutes. A dealer would have meant a tow, a wait for an appointment, and a bill that would have made the day even worse. They loaded up and drove home with two working keys.

“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.”

“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.”

Chrysler 300 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2012 Chrysler 300 key?
Call a mobile locksmith before you call the dealer. Chrysler dealers regularly quote north of $300 for a single Fobik replacement, and that's before you add the tow if the car won't start. Some owners on Chrysler 300 forums have reported dealer quotes between $400 and $600 depending on whether it's an all-keys-lost situation. With me, you skip the tow, skip the appointment, and get it done on the spot for a fraction of what they wanted. I carry OEM-compatible M3N-40821302 Fobiks and cut the Y171 blade on site.
How much more does an all-keys-lost job cost compared to adding a spare?
Are aftermarket Chrysler Fobiks cheaper, and do they actually work?
My 2012 Chrysler 300 shows "Key Fob Not Detected" but the battery is new. What's going on?
Can I program a new Fobik myself on a 2012 Chrysler 300?
