🔧 PRO TIP
The 2019 Chrysler 300 has a Security Gateway Module (SGM) on the CAN bus behind the OBD-II port. It blocks all aftermarket tool communication by default. You need a 12+8 bypass cable or an AutoAuth dongle plugged in before any key programming even starts. That adds about ten minutes of setup. If your locksmith shows up and doesn't know about the SGM, they're going to stare at a "communication error" on their programmer and have no answer for you. The gateway module started with the 2018 model year refresh.

2019 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional

A grandmother flagged me down in the urgent care lot near Westlake Plaza in Thousand Oaks. She needed a spare smart key for her 2019 Chrysler 300 but spent the first few minutes telling me why she picked me, not what she needed done.

Her last locksmith had no license. She only figured that out after the job when his receipt had no company name, no license number, and no callback number that worked a week later. So this time she looked me up first. BSIS license LCO 6792, right there on the state website. She checked it before she ever dialed my number.

I walked her through what I was doing while I did it. AutoAuth dongle into the OBD port to get past the Security Gateway Module. NASTF database pull to get the factory PIN for the Wireless Control Module. Her 300 uses the WCM as the RF hub, part of Chrysler's keyless system on the second-gen platform. Once the PIN came back, I programmed the new M3M-40821302 fob through the correct factory data path using my Autel IM608 Pro. Cut the emergency insert blade on the spot, tested all five buttons, tested push-to-start, tested passive entry on both front doors.

She watched the whole thing from about two feet away. When I handed her the receipt, she turned it over and read every line. Company name, license number, phone number. She said that alone was worth the call.

Chrysler 300 Mobile Service FAQ

Real costs, no dealer surprises

I lost every key for my 2019 Chrysler 300. What does all-keys-lost look like with a mobile locksmith?
I come to you in Thousand Oaks. No tow needed. The process starts with bypassing the Security Gateway Module through a 12+8 cable or AutoAuth dongle, then pulling the factory PIN from the Wireless Control Module through NASTF. From there I reset the immobilizer, program new M3M-40821302 smart keys, and cut the emergency insert blade on site. The all-keys-lost routine on these Chryslers has a timed security countdown built in, so expect 30 to 45 minutes total. Every previously stored key ID gets wiped, so whatever fobs are missing can't start the car. The dealer route means a tow, a wait for parts, and a bill that's a good chunk more than what I charge.
Can you delete my lost or stolen Chrysler 300 keys so they stop working?
Does my 2019 Chrysler 300 smart key have a hidden emergency blade inside the fob?
My 2019 Chrysler 300 shows "Key Fob Not Detected" but the battery is new. What's going on?
Can I buy a 2019 Chrysler 300 smart key online and program it myself to save money?
