Programming your key fob for a 2004 Chrysler Crossfire might seem daunting, but it’s a process you can actually undertake yourself. This guide provides a step-by-step walkthrough, ensuring you can get your remote working again without a trip to the dealership. Let’s get your key fob programmed and your Crossfire ready to roll.
To begin the key fob programming procedure for your 2004 Chrysler Crossfire, ensure you have both of your valid Sentry Keys. The process leverages your vehicle’s existing security system to learn the new key fob commands. Follow these instructions carefully for successful programming:
Step-by-Step Key Fob Programming Instructions:
-
Hood Closure: Start by making sure the hood of your Chrysler Crossfire is completely closed. This is a preliminary step to ensure the system is ready for programming.
-
Initial Key Insertion: Take one of your two working Sentry Keys and insert it into the ignition switch. Turn the ignition switch to the “on” position. This activates the vehicle’s electrical system and prepares it for the programming sequence.
-
First Key Cycle: Leave the ignition in the “on” position for a duration longer than 3 seconds but no more than 15 seconds. After this brief period, cycle the ignition switch back to the “off” position. Remove the key from the ignition. It’s important to keep this first key at least two feet away from the ignition switch to prevent interference.
-
Second Key Insertion: Within 15 seconds of removing the first key, take your second valid Sentry Key and insert it into the ignition switch. Turn the ignition switch to the “on” position once again. This step signals the system to enter programming mode.
-
Entering Customer Learn Mode: Approximately 10 seconds after activating the ignition with the second Sentry Key, you will observe the dash theft-security light begin to flash. Simultaneously, a single audible chime will sound (distinct from the key-in-cylinder chime). These are the indicators that your Chrysler Crossfire system has successfully entered “Customer Learn” programming mode, and is ready to learn a new key fob.
-
Second Key Cycle: Cycle the ignition switch back to the “off” position. Remove the second key and, like the first, keep it at least two feet away from the ignition switch. At this point, the theft-security light should turn off.
-
Programming Button Activation: Locate and press the programming button. This button is typically found on the aftermarket remote start harness that is installed in conjunction with your keyless entry system.
-
Transmitter Start Button Sequence: Within 60 seconds of pressing the programming button, press the start button on your remote start transmitter two times. This action sends the programming signal from your new key fob to the vehicle’s system.
-
Confirmation and System Response: Approximately 10 seconds after completing Step 8, you should hear a single audible chime. The theft-security light will stop flashing and remain on solid for 3 seconds, before turning off. This sequence confirms that the SKREEM Interface module has been successfully programmed to recognize your 2004 Chrysler Crossfire key fob.
-
System Test: The system will then attempt to remote start the engine approximately 15 seconds after Step 8. To shut down the remote start system, simply press the brake pedal.
Important Note: In some 2004 Chrysler Crossfire models, the vehicle might start and then stall on the first remote start attempt during the SKREEM Interface learning procedure. This is considered normal behavior during the programming process. The second remote start attempt should be successful. If your vehicle fails to start after these steps, it’s recommended to consult a troubleshooting guide specific to your remote start system or seek professional assistance.
By following these steps, you should be able to program your 2004 Chrysler Crossfire key fob and regain full remote functionality. This DIY approach can save you time and money, getting you back on the road with a fully functional key fob.
