How to program your key fob
This remote can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new remote, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

Chrysler 300 key fob battery
Your Chrysler 300 key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Energizer CR2032 Lithium Coin Batteries (4-pack) on AmazonHow to replace the battery
- 1 Look for a small notch or screw on the side of the fob where the key blade meets the buttons.
- 2 Pry the housing apart with a coin or small flathead (or remove the screw).
- 3 Pop out the old coin cell, noting its orientation.
- 4 Insert the new battery the same way up, then snap the case shut.
- 5 Test the buttons — if they work, you're done.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Try not to touch both faces of the new battery; skin oils shorten its life.
- If the buttons still don't respond after a new battery, the remote may need re-syncing or programming.
