Lost your key fob or need to program a new one for your 2008 Mitsubishi Endeavor? Don’t worry, programming your key fob and keys for your Mitsubishi Endeavor can be done at home with a few simple steps. This guide provides you with clear, easy-to-follow instructions to program both the key and remote functions of your 2008 Mitsubishi Endeavor key fob, saving you time and money compared to dealership programming.
Programming the Key Portion of Your 2008 Mitsubishi Endeavor Key
Before you begin, it’s essential to understand that programming the key portion and the remote portion of your key fob are two separate procedures. Let’s start with the key programming. This process ensures that your new key will start your vehicle.
Important Note: You will need to have your new key cut by a locksmith or dealership before proceeding with these programming steps. This procedure is for teaching your vehicle to recognize the transponder chip inside the new key.
Here are the steps to program the key portion of your 2008 Mitsubishi Endeavor key:
-
Insert a Working Key: Take your existing, working key and insert it into the ignition cylinder. This is the key you currently use to start your Mitsubishi Endeavor.
-
Turn Ignition ON and OFF: Turn the ignition to the “ON” position (just before starting the engine, where the dashboard lights illuminate). Hold it in this position for 5 seconds. Then, turn the ignition back to the “OFF” position and remove the key.
-
Insert Second Working Key: Within 10 seconds of removing the first key, insert a second working key into the ignition and turn it to the “ON” position. You should observe the security light on your dashboard flashing twice. This indicates that the system has recognized the second working key and is ready for new key programming. Turn the ignition back to the “OFF” position and remove this second key.
-
Insert the New Key: Now, within 10 seconds, insert the new, unprogrammed key into the ignition cylinder and turn the ignition to the “ON” position.
-
Wait for Security Light: Keep the ignition in the “ON” position. The security light on your dashboard should illuminate for approximately 3 seconds. This steady light confirms that your new key has been successfully programmed to start your 2008 Mitsubishi Endeavor.
-
Test and Program Additional Keys (Optional): Turn the ignition to the “OFF” position and remove the newly programmed key. Test the new key to ensure it starts your vehicle. If you have more new keys to program, repeat steps 4 and 5. Remember, all new keys must be programmed within 30 seconds of the security light flashing twice in step 3.
-
Exit Programming Mode: If you don’t need to program any more keys, simply leave the ignition switched to the “ON” position for more than 30 seconds. This will automatically exit the key programming mode.
Programming the Remote Portion of Your 2008 Mitsubishi Endeavor Key Fob
Now that you’ve programmed the key to start your vehicle, let’s move on to programming the remote portion of your key fob. This will enable the keyless entry functions like locking and unlocking your doors remotely.
-
Locate the OBD-II Data Port: The OBD-II (On-Board Diagnostics II) data port in your 2008 Mitsubishi Endeavor is typically located underneath the driver’s side dashboard. Look for it to the right of the steering column. You might need to look under the dash panel to find it.
Understanding the OBD-II Port: This image shows a typical OBD-II port, similar to the one you’ll find in your 2008 Mitsubishi Endeavor. It’s a standardized port used for vehicle diagnostics and, in this case, key fob programming.
-
Insert Keys in Ignition (OFF Position): Insert your key into the ignition cylinder but leave it in the “OFF” position. Do not turn the ignition ON.
-
Prepare Jumper Wire and Connect Terminals 1 and 4: You’ll need a jumper wire or a similar conductive wire to connect terminals 1 and 4 of the OBD-II data port. Important: Before connecting, carefully identify terminals 1 and 4 on your OBD-II port. Refer to your vehicle’s repair manual if you are unsure. Ensure there are metal contact pins in terminals 1 and 4. Connect the jumper wire between these two terminals and leave it connected throughout the programming process.
-
Press Hazard Switch Six Times: Within 10 seconds of connecting the jumper wire, press the hazard light switch (the button that makes your front and rear turn signals flash simultaneously) six times. If done correctly, the doors of your Mitsubishi Endeavor should automatically lock and unlock once. This indicates that the system has entered the key fob programming mode.
-
Press LOCK Button on Remote: Take the remote you want to program and press the “LOCK” button three times within 10 seconds. After successful programming of this remote, the doors should lock and unlock one more time, confirming the programming.
-
Program Additional Remotes (Up to 4): If you have more remotes to program (up to a maximum of 4, including any existing working remotes), repeat step 5 for each additional remote within one minute. Each successful remote programming will be indicated by the doors locking and unlocking once.
-
Disconnect Jumper Wire and Remove Keys: Once you have programmed all desired remotes, disconnect the jumper wire from the OBD-II port and remove the key from the ignition.
Congratulations! You have now successfully programmed both the key and remote functions for your 2008 Mitsubishi Endeavor key fob. Test all your newly programmed keys and remotes to ensure they are working correctly. If you encounter any issues, double-check each step and ensure you have followed the instructions precisely. If problems persist, it may be necessary to consult a qualified locksmith or your Mitsubishi dealership for further assistance.
