connect car control with car

How can I connect the command with the car again, it is a Seat Cordoba in 1998, it comes in the User Manual

I don't understand the question?

If I keep in charge of the car and the car does not open because it has lost the frequency I have to connect it again to work again and I do not have the manual and I do not

If it is control that comes for the alarm, you must look for the alarm service button, pass the car key as an ACC (accessories), when the dashboard indicators are educated, you step on the service button and the button of your new control until it sounds and loose, with that it is already programmed. If it is the control of an original car system you must take it to service to be scheduled in the EMC (computer) of the car.
