Lost or need to reprogram your key fob for your 2000 Mitsubishi Montero Sport? Don’t worry, you might be able to handle it yourself without a trip to the dealership. This guide, based on community experience, walks you through the steps to program your 2000 Mitsubishi Montero Sport key fob at home.
Step-by-Step Key Fob Programming Instructions
Here’s how to program your keyless entry remote for your 2000 Mitsubishi Montero Sport. This method involves using the Data Line Connector (DLC) located under your driver’s side dash.
-
Locate the DLC Connector: Find the Data Line Connector (DLC) beneath your steering wheel, on the driver’s side dash. It has a tapered shape. We will be using the wider, top row of cavities.
-
Prepare the Jumper Wire: Take a paperclip or a suitable jumper wire.
-
Ignition and Jumper Wire Connection:
- Insert your keys into the ignition switch, but leave the ignition in the OFF position.
- Ensure metal contact pins are present in terminals 1 and 4 of the DLC.
- Connect terminal 1 to terminal 4 of the DLC using your jumper wire.
-
Initiate Programming Mode: This step needs to be performed quickly. Within 10 seconds of connecting the jumper wire:
- Turn the ignition key to the ACC (Accessory) position.
- Immediately turn the key back to the OFF position for one second.
- Repeat this ACC to OFF cycle two more times (for a total of three cycles).
- Speed is crucial here. If you are too slow, you’ll need to disconnect the jumper wire and begin the process again from step 3.
-
Transmitter Registration:
- Press either the Lock or Unlock button on the key fob transmitter three times within 10 seconds.
- If programming is successful, the vehicle’s doors will lock and unlock once to confirm.
-
Programming a Second Transmitter (If Applicable):
- If you have a second key fob to program, repeat step 5 immediately within one minute of programming the first transmitter.
- After successfully programming the second transmitter, the doors will again lock and unlock once.
-
Final Steps:
- Disconnect the jumper wire from the DLC.
- Remove the keys from the ignition.
Troubleshooting Tip: Grounding Issues
In some cases, you might encounter issues with grounding through pin 4 of the DLC. If the standard procedure doesn’t work, consider this alternative grounding method:
- Instead of relying on pin 4 for ground, connect pin 1 directly to a known ground source. A convenient ground point can be the metal rim of the cigarette lighter socket (ensure you touch the metal edge, not the positive terminal inside).
By following these steps, you should be able to program your 2000 Mitsubishi Montero Sport key fob yourself. This DIY method can save you time and money, getting you back on the road with a functioning remote. Good luck!
