Need a Chrysler 300 key replacement in McKinney and nearby cities? 2008-2010 cars use a FOBIK key, and 2011-2023 Chrysler 300s run a proximity smart fob. Apex Locksmith Pros comes to you, pulls the key data by VIN, and cuts and programs the Chrysler 300 key on-site so the immobilizer accepts it. Nothing is dispatched until you have the flat total from our phone quote, and there is no call-out fee.

What Key Does the Chrysler 300 Use?
The Chrysler 300 used two main systems over its run. Earlier cars came with a remote-head key that turned a standard ignition cylinder, with a transponder chip in the head and a separate lock/unlock remote. Most 300s, though, run proximity smart fobs with push-to-start. Newer model years moved to higher-security encryption, which is why some of those fobs cost more and take longer to program. Either way, a fresh fob has to be cut to the door/ignition (laser-cut blade on the smart-key cars) and then registered to the car's immobilizer through the OBD port. Our programmers pull the fob data by VIN and write it to the security module, so the key both turns the car over and works the remote functions.
The most common 300 call
A common one on the 300: the push-to-start fob stops working at range or only starts the car when you hold it right against the START button. That's almost always the little CR2032 coin cell inside the fob running flat, not a dead fob. Pop it open, drop in a fresh battery, and it usually wakes right up. If a new battery doesn't fix it, the rubber START button pad or the fob board can be worn, and at that point a replacement fob programmed to your VIN is the real fix.
Chrysler 300 Key Fob FCC IDs
Flip your fob over: the FCC ID is printed on the back of the case. Find it below, or just read it to our dispatcher. It tells us the exact remote your Chrysler 300 takes before the van rolls out.
| Years | Key type | FCC ID |
|---|---|---|
| 2008-2010 | FOBIK key | IYZ-C01C |
| 2011-2023 | Proximity smart fob | M3N-40821302 |
Trim and market can change the fob, and several IDs often fit one model year. We confirm the exact part by VIN on every job, so a mismatched guess never reaches your driveway.

What Do Chrysler 300 Owners Ask?
Straight answers for Chrysler 300 owners in McKinney and nearby cities: which key your car uses, what to have ready and how on-site programming works.
Yes. An all-keys-lost 300 takes longer than a spare because we have to pull key data by VIN and put the immobilizer into learn mode, but we do it on-site. Bring the title or registration so we can confirm you own the car.
It depends on the year and whether it's a remote-head key or a push-to-start smart fob, but we're typically well under dealer pricing. Smart proximity fobs run more than the older transponder keys. Tell us your year and we'll quote it before we head out.
No. We program at your location through the OBD port under the dash, so there's no tow. As long as the car is where you are, we cut and register the new fob right there in the driveway or lot.
Sure. A 2014 300 runs the proximity smart fob with push-to-start, programmed to the immobilizer through the OBD port at the car, with the laser-cut blade matched to your door. The earlier remote-head turn keys are covered the same visit. Any 300 year works; the VIN tells us which fob and which encryption we're dealing with.
It depends on the year. 2008-2010 Chrysler 300: IYZ-C01C; 2011-2023 Chrysler 300: M3N-40821302. The ID is printed on the back of your fob case. Trim and market can change it, so we confirm the exact part by VIN before the van rolls out.
