It's hard to say for sure without knowing what type of opener you have. But most newer openers program the same way. There is a button on the motor itself, usually red, purple, green, etc. If you push and release this button, then immediately go and hold the button in the car down for about 5-10 seconds they should sync up.
If that doesn't work, you would probably be better off looking up the opener manual and seeing if they have directions to do it.
Good Luck!
