🔧 PRO TIP
The 2023 Chrysler 300 smart key fob takes a CR2032 and carries a transponder chip inside the same housing. That matters because when owners complain about intermittent key-not-detected warnings, they chase the fob first, but the actual weak point is often the battery contact tension after years of drops. Before anything else, pop the fob open, clean the contact plates, and seat a fresh CR2032 flat. Also worth knowing: the emergency blade tucks inside the fob body behind a small release button on the side. A lot of 300 owners have never pulled it out. If the fob stops talking to the car, that blade is your way in, and holding the fob against the start button with the brake pressed will still fire the engine even on a completely dead battery.

2023 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional

I got a call from a fleet van driver who works out of an oil change shop in Downtown Fallbrook. His company runs a 2023 Chrysler 300 as a management vehicle, and a previous locksmith had already been at it.

The story came out in pieces while I was driving over. He had searched for a locksmith, clicked a cheap ad, and someone showed up and quoted a number that more than tripled by the time the job was done. The fob technically started the car, but every remote button was dead. Lock, unlock, the trunk, all of it. Just gone. He had been living with it for two weeks because he was not sure whether the problem was the fob, the programming, or something the previous tech had broken.

His first question when I called him back was how to verify I was legitimate. That is a fair question, and I respected it. I gave him my BSIS license number right there on the phone and told him to pull up the state site while we were still talking. He did. Then he booked the appointment.

When I arrived, I connected my programmer to the diagnostic port and pulled up the key configuration. What I found was a partial registration, the transponder side had enrolled but the remote functions had never completed pairing. Classic sign of someone using marginal equipment or rushing the process. I cleared the existing key data and ran a full programming sequence, transponder and remote together, the way it is supposed to go.

All five buttons came back. Lock, unlock, trunk, panic, and the remote start function the car was built with. I walked every button in the parking lot before I packed up.

His comment at the end was something like: I should have just called you first. The dealer quote he had gotten afterward, before finding me, would have cost him considerably more than what I charged. The previous scam locksmith had charged more than both of us and still left the job half done.

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”

Chrysler 300 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my 2023 Chrysler 300?
Call a mobile locksmith before you call a tow truck. Dealer all-keys-lost service on the 300 typically requires an appointment, sometimes an overnight, and the quote tends to be steep before you factor in towing a car that won't start. A mobile locksmith comes to your location in Fallbrook, pulls the necessary security data through the diagnostic port, wipes the old key records, programs new fobs, and tests everything on site. No tow, no waiting room, no shop markup. If you are near Downtown Fallbrook, I can usually get there the same day. Call for a real quote before assuming the dealer is your only option.
Can you delete a lost or stolen key from my Chrysler 300 so it no longer works?
Does the 2023 Chrysler 300 smart key fob have a hidden emergency blade?
