Professional 2020 Chrysler 300 key programming by EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2020 Chrysler 300 runs a security gateway module that sits between the OBD port and the rest of the car's network. Any key programming tool has to authenticate through that gateway before it can even talk to the immobilizer. That's not a workaround or a hack, it's just the architecture on these later LX-platform cars. A good key programmer handles it, but it adds a step before actual fob registration begins. Also: the fob takes a CR2032, and a low-but-not-dead battery on these can throw a detection warning without fully killing the remote. Swap the cell first before assuming the fob or the module is the problem.

2020 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional

Over in Thille, near the Montalvo corridor, a guy flagged me down while I was wrapping up another call. Not literally, but close enough: he texted while I was still loading my kit back into the van.

He worked for an oil change shop nearby and his company ran a 2020 Chrysler 300 as a driver vehicle. A few weeks earlier, someone in the shop had called a locksmith after the fob started acting up. The ad said cheap, the phone quote was cheap, and the guy who showed up charged multiples of that and left the job half done. The fob would start the car but none of the remote buttons registered. Every time someone tried to lock the car from outside, nothing.

He found me through Google Guaranteed and his first question wasn't about price. It was whether I was licensed. That's the right question. I gave him my BSIS license number on the phone and told him to pull it up on the state site before I even drove over. He did. That's exactly what you should do with any locksmith in California.

When I got there, I connected through the gateway, cleared the partial registration the previous guy had left behind, and ran a full fob enrollment. All five buttons came back clean. The ignition read the transponder properly. The whole thing took about forty minutes, most of which was the gateway authentication and the programming sequence, not the physical work.

He mentioned the dealer quote he'd gotten before calling the first locksmith. It was a number that made the scam locksmith's inflated price look almost reasonable by comparison. My price was what I quoted, nothing added. That's the whole story.

“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”

Chrysler 300 Mobile Service FAQ

Real costs, no dealer surprises

My key shell cracked and the fob is falling apart. Can you fix it without reprogramming?
Usually, yes. If the circuit board inside is intact and undamaged, I can transfer it into a new compatible shell on site. The immobilizer is registered to the electronics, not the plastic housing, so a clean shell swap doesn't require a new programming cycle. I've done this on fobs that snapped clean in half, fobs with broken battery covers, and a couple that clearly lost a fight with a parking lot. Where it gets more involved is if the board itself is cracked, corroded from a battery leak, or if the previous owner tried to glue it back together and got something on the contacts. In those cases, a full replacement and programming is the cleaner path. Either way, I carry shells and can assess it on the spot before you commit to anything.
What exactly is a smart key and how is the 2020 Chrysler 300's setup different from a regular key?
My 2020 Chrysler 300 is showing a key-not-detected warning. Where do I start?
