#1 of 2 Mitsubishi Transponder Keys & Keyless Remotes by 5280 Jan 30, 2009 (6:49 pm)
After searching the forum I was unable to find an answer to my question.   I own a 2003 Montero Sport Limited which I bought used a little over a year ago. The dealer provided only one transponder key at the time I purchased the vehicle. Later I discovered my truck had been a repo, hence only the one key. This is the first vehicle I ever bought which had a transponder key, and I though "I will just go to the hardware store and get a couple of more made," otherwise I would have negotiated a little better to obtain an additional transponder key and keyless remote. Live and learn!    The dealership wants $100 per transponder key and $150 per keyless remotes (this of course includes "programming"). Any suggestions on alternatives to paying these outrageous dealer prices?    I did get a key cut at the hardware store which gets me into the door if I lock my keys in however, as you know, the ignition will not start without the transponder chip attached.    My email address is johnxhewel (at) yahoo (dot) com for anyone who might have a better idea than paying dealership prices.    Thanks for your time and any help possible! John
#2 of 2 Keyless Entry Programming by 5280 Mar 07, 2009 (1:44 am)
I have a 03 Montero Sport Limited and I spent a lot of time trying to obtain and program keyless entry remotes without having to pay dealership prices. I found two (2) remotes online. One on Ebay and another from an online company. I spent $30 for the remote purchased from the online company and $17 for the remote purchased on Ebay. Here are the programming instructions I received with my remote. These instructions worked for me without any problems.   1. Located underneath the drivers side dash is the DLC (Data Line Connector). The DLC is tapered on both ends. The terminals needed to complete the programming are on the top row.   2. Insert keys in ignition and leave in the off position. Make sure there are metal contact pins in terminals 1 and 4 from the left to the right and connect the Data Line Connector terminal 1 to 4 with a jumper wire. A paper clip can work as the jumper wire.   3. Within ten (10) seconds after connecting the jumper wire, turn the ignition switch to the ACC (Accessory) position and then back to the OFF position for one (1) second and repeat 2 times. (Note that as soon as the jumper wire is connected in terminal 1 and 4 you must immediately turn the key to ACC (Accessory) then OFF repeatedly 3 times. If this is done too slow or the programming is not successful, start over by removing the paper clip and starting the process again.)   4. Press the Lock or Unlock button on the transmitter to be registered three times within 10 seconds. Upon successful programming the door will lock and unlock once.   5. If there are 2 transmitters, register the first, then register the second (Just the remote button, press 3 times) using the same procedure within one minute. After completing the second programming the doors will lock and unlock once. Disconnect the programming wire (paper clip) and remove keys. (Note: Up to four (4) remotes can be programmed to a single vehicle.)   If I can be of any help you can contact me via email johnxhewel (at) yahoo (dot) com.
