🔧 PRO TIP
These 300s continue on FCC M3N-40821302 but with an updated AES chip. If you bought eBay fobs, some Chrysler dealers program them cheap (around $100 for multiple keys), while mobile locksmiths typically quote $100-200 for the same job.

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

She was at a brewery patio in El Cajon on a first date and her purse was gone. Someone grabbed it from the bench. Car keys, wallet, phone. She borrowed the bartender's phone and called the police first, then her roommate, then me.

Her 2020 Chrysler 300 was in the brewery lot with zero keys. The dealer told her roommate they could order a FOBIK but it would take 3 to 5 business days and the car would need to be towed in. They also recommended checking the locks since the stolen FOBIK could still open the doors. Combined estimate was over $700.

I got there that night. All-keys-lost is a different procedure than adding a spare. When you add a key, the car already trusts an existing key and just adds a new one to its list. AKL means I clear the entire key memory and start fresh so the stolen FOBIK can no longer start the engine. I used my IM608 to access the SKIM module, pull the PIN, wipe the old key data, and program two new keys from scratch. Her FOBIK, FCC ID M3M-40821302, was a 5-button key. I decoded the lock, cut the blade, and had both FOBIKs working before her roommate even arrived.

She drove home that night. Total was $283 for two new keys. The dealer estimated $482 plus a tow and a multi-day wait. The stolen FOBIK can still physically enter the door lock but the immobilizer won't let the engine start. She had two fresh keys and the old one was dead to the car.

Chrysler 300 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my Chrysler?
Call a mobile locksmith, not the dealer. Chrysler dealer AKL quotes run $400 to $600 or more, and that is before towing if you cannot drive the car in. One owner was quoted $600 by a dealer, while a locksmith handled the same Stellantis job for $275. We come to your location in El Cajon, extract the PIN, reset the immobilizer, cut and program the key, and test everything before we leave. No tow, no overnight, no dealer markup.
