Are you looking to program a new key fob for your 2007 Chrysler 300? Losing or damaging your key fob can be a real hassle, but fortunately, programming a new one can often be done yourself, saving you a trip to the dealership. This guide provides clear, easy-to-follow instructions for programming a 2007 Chrysler 300 key fob, ensuring you get back on the road quickly.
This method requires you to have two existing, already programmed keys. If you don’t have two working keys, you may need to visit a dealership or locksmith for programming assistance. However, if you have the necessary keys, follow these steps to program your new 2007 Chrysler 300 key fob:
-
Initiate Programming Mode with First Key: Begin by inserting one of your currently programmed transponder keys into the ignition lock cylinder. Turn the ignition switch to the ON position. This means turning the key far enough to power the car’s electronics, but not so far as to start the engine.
-
Timing is Key – First Key Cycle: Leave the first key in the ON position for a duration of 5 to 15 seconds. It’s crucial to stay within this time frame. After the time has elapsed, turn the ignition switch back to the OFF position, removing the first key from the ignition.
-
Enter Customer Learn Mode with Second Key: Within 10 seconds of removing the first key, insert your second pre-programmed transponder key into the ignition cylinder. Again, turn the ignition switch to the ON position.
-
System Confirmation: Keep the second key in the ON position. You should observe the Vehicle Theft Security System (VTSS) lamp or the Sentry Key Immobilizer System lamp (the specific lamp may vary depending on your exact 2007 Chrysler 300 model) begin to flash. Accompanying this visual cue, you should also hear an audible tone. These indicators signal that your Chrysler 300’s system has successfully entered the “Customer Learn” programming mode, ready to accept a new key fob.
-
Program the New Key Fob: Now, within 45 seconds of entering the “Customer Learn” mode, turn the ignition switch to the OFF position with the second key still inserted, and then remove the second key. Immediately insert the new, unprogrammed transponder key into the ignition cylinder. Turn the ignition switch to the ON position with the new key.
-
Confirmation of Successful Programming: After approximately 10 seconds, you will hear another audible tone. Additionally, the indicator lamp (VTSS or Sentry Key Immobilizer System lamp) will illuminate and remain lit for 3 seconds. This sequence of tones and light signals confirmation that you have successfully programmed your new 2007 Chrysler 300 key fob.
-
Programming Additional Key Fobs (Optional): If you wish to program more new key fobs, simply repeat steps 1 through 6. This process allows you to program multiple key fobs in sequence, as long as you have entered the “Customer Learn” mode.
2007 Chrysler 300 Key Fob Programming Instructions
Important Considerations:
- Two Programmed Keys Requirement: As mentioned, this on-board programming method for a 2007 Chrysler 300 requires two already programmed and working keys. If you only have one or no working keys, you will not be able to use this procedure. Consult your owner’s manual or your local Chrysler dealership for alternative programming options. In such cases, professional diagnostic tools are typically needed to bypass the security measures and program new key fobs.
- Check Your Owner’s Manual: While these instructions are generally accurate for the 2007 Chrysler 300, it’s always a good practice to verify the specific key fob programming procedure in your vehicle’s owner’s manual. There might be minor variations depending on the exact trim level or optional features of your car.
- Professional Assistance: If you encounter any difficulties or are unsure about any step in this process, it is always advisable to seek assistance from a qualified automotive locksmith or your Chrysler dealership. They have the expertise and equipment to handle key fob programming, even in situations where you don’t have two existing keys.
By following these detailed steps, you should be able to successfully program your new 2007 Chrysler 300 key fob and regain full access and functionality for your vehicle.
