Check the battery in your key pad.
If the key looks like a circuit board, try the slot underneath the steering wheel.
It is located on the computer inside the drivers door. Just remove the door panel and it will be on the computer.
On the opener there should be a button by where the thin wires attach. Push the button, probably a square one and it should flash. If you have a transmitter, push it and the button should flash. If there is a key pad for the door, push the button on the opener then put in a 4 digit number on the key pad and push Enter. That will be the new code.
You will find it on the right hinge of the trunk
On the right hinge of trunk lid
Each vehicle with a key pad has it's own factory code
My 1995 Ford Explorer XLT has the keyless entry pad on the drivers door
