How to programm a keyless entry keypad on a 2001 mitsubishi montero sport?

I need sombody to show me how to program a keyless netry keypad on a 2001 mitsubishi montero sport. The one that I have stop working . I has a new battery.|||Never seen a Mitsubishi with a keypad entry. You just talking about the remote? Changing a battery should not make a remote quit working, the remote may just have gone bad. The dealer needs all the remotes and the vehicle to program any new remotes with their Mutt II scan tool.|||Do you own a Mitsubishi Dealership, with a person trained in the use of the MUT tester. No? take it to someone who is. My $5000 Snap-on Modis scan tool won't.
