Emergency 2012 Chrysler 300 key fob made from scratch by EZ Car Keyz Thousand Oaks CA
🔧 PRO TIP
The 2012 Chrysler 300 uses a five-button smart fob with a CR2032. These are FOBIK-style keys, meaning the blade folds into the fob body rather than sitting on a separate ring. That matters because when the fob hits the floor or gets sat on, the blade pivot can crack the shell from the inside and the battery contacts shift just enough to cause intermittent starts and a key-not-detected warning on the dash. A lot of owners chase a programming problem when it's actually a cracked fob housing putting pressure on the board. Pop it open before you assume the key died. Also worth knowing: the 2012 300 sits squarely on the hot list for large sedan theft in California. It's not the top target, but it's noticed. If you're parked overnight near The Oaks Mall Area, the security system is working harder than you think.

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.”

“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 a key for the 2012 Chrysler 300?
Call a mobile locksmith before you call the dealer. Dealers charge a significant amount for a single smart fob on this car, and that's before you factor in a tow if you're already locked out. With EZ Car Keyz, you get the fob, the cut blade, and the programming done at your location, no appointment, no tow, no separate line items for each piece of the job. If you still have one working key, adding a spare is the least expensive path. If all keys are lost, the job is more involved but still a fraction of what the dealer route costs.
How much more does all-keys-lost cost compared to just adding a spare?
Do aftermarket fobs work on the 2012 Chrysler 300, or should I buy OEM?
My 2012 Chrysler 300 starts fine but the fob buttons stopped working from any distance. What's going on?
I bought a used 2012 Chrysler 300 and only got one key. Should I be worried about the previous owner's fob still working?
