Chrysler 300 Key Replacement by Year: Which Key Do You Have?
The Chrysler 300 is a sedan that owners use for commuting, errands, and longer drives. Its key setup varies by model year, and trim can also matter when identifying the right replacement. Knowing whether you have a traditional chip key, a fob-style key, or push-to-start helps us understand what kind of service your 300 may need.
About 1998–2007: Chip key
These Chrysler 300 models use a key with a chip. If the key is lost or damaged, tell us the year and describe the key so we can discuss the replacement your vehicle calls for.
Later models: Fob-style key or push-to-start
Many later 300s use a fob-style key with no blade in the ignition, or a push-to-start setup. These systems differ from a traditional chip key, so let us know whether your car starts with a turn of the key or a button.

On Your Chrysler 300, Is the Problem the Fob or the Car?
A Chrysler 300 key fob that stops responding can make it hard to tell whether the issue is the fob, the key, or something else. These quick checks can help you describe what is happening when you call; they aren’t a substitute for checking the vehicle and key together.
- Try a spare key or fob — If a spare starts or unlocks the 300, that points to a problem with the key you were using. Tell us what the spare can do and what the other key cannot.
- Notice what happens when you use the key — Does the vehicle respond to the fob, or does nothing happen? If the 300 has push-to-start, mention that when you call; if it uses a key in the ignition, describe whether the key turns.
- Check the key for visible damage — Look for a cracked case, a damaged blade, or buttons that feel stuck. Don’t force a damaged key into the ignition or keep pressing a button that appears jammed.
- Separate a lockout from a key failure — If your key is inside the 300 and you can’t get in, say that clearly. We also offer car lockout service, which is different from replacing a lost or broken key.

Key and Fob Help for Chrysler 300 Drivers
From an older 300 with a chip key to a later model with a fob-style key, the right service depends on the key setup and what has gone wrong. We come to you, so you can explain the issue at the vehicle rather than arranging a visit to a storefront.
- Replace a lost Chrysler 300 key — Tell us if every key is missing or if you still have one that works. We also help with Chrysler key replacement for other models.
- Replace a Chrysler 300 key fob — If your fob is missing or damaged, let us know whether your 300 uses a fob-style key or push-to-start. From $120 for car key replacement.
- Program a replacement fob — A replacement fob may need programming for the vehicle. We offer key fob programming; programming starts at $80.
- Address a damaged or unreliable key — Describe whether the key is cracked, worn, or no longer working as expected. We offer car key repair and key fob repair, as well as replacement options.
- Arrange a second key for another driver — If you share the 300, tell us whether you have one working key or more than one. We offer key duplication, and the year and trim help identify what kind of key your sedan uses.
Common Chrysler 300 Key and Fob Problems
A sedan shared between drivers or used for daily trips can leave you relying on a single key or fob. Here are common situations to mention when you contact us, so we can focus on the problem you’re facing with your Chrysler 300.
All keys are lost
If you have no working key for the 300, tell us the model year and whether it uses a chip key, a fob-style key, or push-to-start. Lost car keys start at $120.
The fob buttons don’t respond
If the fob stopped working, note whether the car still starts or whether none of its functions respond. We offer key fob battery replacement and fob programming.
The key is damaged
A cracked fob case or damaged key can make everyday use difficult. Describe the damage and whether you have another working key for the car.
The key is locked inside
If you can see the key inside your 300 but can’t get to it, ask about car lockout service rather than a replacement. Let us know whether the doors are locked and where the key is visible.

Frequently asked questions
How long does Chrysler 300 key replacement take at the car?
The time depends on the 300’s year, key type, and whether you need a replacement key or fob programming. Tell us what key you have and what happened so we can discuss the job before we begin.
Will my lost Chrysler 300 key still work after you replace it?
That depends on the key system and the service performed. Tell us a key is missing when you call, and we’ll explain what applies to your 300 before starting the replacement.
Can you help if I’m locked out of my Chrysler 300 and the key is inside?
Yes, we offer car lockout service and are open 24/7. When you call, say that the key is inside the 300 so we can address the lockout rather than a missing-key replacement.
Can two drivers share a Chrysler 300 with separate keys?
We offer key duplication, so you can ask about getting another key for a second driver. The 300’s year and key type help determine what kind of duplicate is needed.
