Losing or needing to replace your key fob for your 2010 Chrysler 300 can be an inconvenience. Luckily, programming a new key fob for your vehicle can often be done yourself, depending on whether your Chrysler 300 is equipped with the Electronic Vehicle Information Center (EVIC). This guide will walk you through the steps for programming your 2010 Chrysler 300 key fob, covering both methods to help you get back on the road quickly.
Programming Your 2010 Chrysler 300 Key Fob with EVIC
If your 2010 Chrysler 300 has the EVIC system, programming a new key fob is relatively straightforward. The EVIC, accessible through your car’s menu, allows you to directly enter a key fob training mode, making the process user-friendly even without existing programmed fobs. Here’s how to do it:
- Access the EVIC Programming Feature: Navigate through your EVIC menu using the steering wheel controls until you find the “TRAIN REMOTE” option.
- Initiate Training Mode: Select “YES” when prompted to train a remote. Press the MENU button to confirm your selection. The EVIC will display “PRESS REMOTE LOCK & UNLOCK THEN PRESS UNLOCK” and you will hear a chime, signaling that the system is ready for programming.
- Program Your Key Fob: Within approximately 30 seconds, press and hold the LOCK and UNLOCK buttons simultaneously on the new key fob for a few seconds, then press the UNLOCK button again. A chime will sound to confirm successful programming of each key fob. You can repeat this step to program up to four key fobs in total.
- Complete the Programming: Once you have programmed all desired key fobs, press the MENU button again. The EVIC should display “TRAIN DONE ‘X’ TRAINED,” indicating the number of fobs successfully programmed. If no fobs are programmed within 30 seconds, the system will time out and display “TRAIN TIMEOUT.”
Important Note: When using the EVIC programming method, be aware that all previously programmed remotes will be erased when you successfully train even one new remote. Make sure to reprogram all your existing and new key fobs during this process.
Programming Your 2010 Chrysler 300 Key Fob Without EVIC
If your 2010 Chrysler 300 is not equipped with EVIC, or if you prefer an alternative method, you can program a key fob using a sequence of button presses, but this method requires at least one already programmed key fob. If you have lost all your key fobs, you will need to visit a dealership or a qualified locksmith for programming.
Here are the steps for programming a 2010 Chrysler 300 key fob without EVIC:
- Turn Ignition ON: Insert your programmed key fob into the ignition and turn the ignition switch to the “ON” position. Do not start the engine.
- Press and Hold UNLOCK: Press and hold the UNLOCK button on the programmed key fob for a minimum of 4 seconds, but no longer than 10 seconds.
- Press Panic Button: While still holding the UNLOCK button, press and release the PANIC button on the programmed key fob.
- Release Buttons: Release both the UNLOCK and PANIC buttons. You should hear a chime sound, indicating that the system has entered programming mode.
- Program New Key Fob: To program a new key fob, press and hold the LOCK and UNLOCK buttons simultaneously on the new fob for three seconds, then press the UNLOCK button. Listen for a chime after programming each new transmitter, confirming successful programming.
- Exit Programming Mode: Turn the ignition OFF or wait for 32 seconds. The system will chime again to signal that it has exited programming mode.
Caution: It’s strongly advised AGAINST attempting to program your key fob by grounding wires on the BCM (Body Control Module) as suggested in some online forums. This method carries a significant risk of damaging your vehicle’s electrical system. Always follow the manufacturer-recommended procedures for key fob programming.
Final Thoughts
Programming a key fob for your 2010 Chrysler 300 can be a DIY task, especially if you have the EVIC system. Understanding the correct procedures for both EVIC and non-EVIC methods can save you time and money. However, if you encounter difficulties or have lost all your original key fobs, seeking assistance from a professional locksmith or dealership is recommended to ensure proper and safe programming of your new key fob. Always refer to your owner’s manual for the most accurate and detailed instructions specific to your vehicle model.
