Is there any easy way to connect button in my BMW and Remote controlled Garage door?

If you have the built-in Homelink system you can find programming instructions on the Homelink website:

Just select your vehicle and garage door opener model.Is there any easy way to connect button in my BMW and Remote controlled Garage door?
I don't know what ';switch'; you are referring to, but the following will give some ideas of what can be done.





Remote controlled garage door openers operate on a short range ( low power) radio frequency. So that all of the garage doors in your transmitting range don't operate when someone opens their door, they have many different frequencies available. The frequency of your unit is printed on the receiver unit, which is normally by the motor assembly that opens the door.





The only way to have a button in your car operate the door is to have it connected to a transmitter operating on the same frequency as your door. You could open your transmitter unit (or buy a spare with the same frequency.) and connect the wires that go to the opener button to a button on your dash. (or wherever) Then hide the transmitter behind the dash, or wherever you wish. That way it would appear that you had no hand held remote opener in your car, but had a built in opening system.





You would need to use a ';momentary on'; switch. That is one that is only activated while you are touching it. (works just like the button on the hand held unit) That type of switch is available in many styles, so it would be a matter of finding one that matched your car's switches.





Be advised that the more metal blocking the signal (dash, firewall, hood, etc.) the shorter the range. Also put the remote unit in a hidden, but accessible spot in case you need to change batteries. The option here is to find out what operating voltage the remote unit uses (usually says on the case, or in the remote's documentation, or you can bring the remote to Radio Shack and they can look at the battery arrangement and tell you the voltage. IE: 2 batteries in series = 3 volts, 4 in series = 6, vs any number in parallel =1.5) and hard wire it to your fuse block through a voltage reducer. (A voltage reducer can be found at your local Radio Shack to convert 12v as used in the car's electrical system to 1.5, 3, 4.5, 6, 7.5, 9, or 10.5 volts as needed. Not needed if the remote is 12 volts.) You would remove the batteries and connect the wires from the voltage reducer to the + and - connections where the batteries connected to the remote unit.





All of this is fairly simple electronics, but not for you to attempt if you are one of the people who think that electricity is ';magic';.
Most modern garage door openers come with one or two remote controls, The double door Garage Door Opener usually has a one half horsepower motor to lift the large double doors. You only have to set your personal code into the opener to match the same code you will want to use in the remote controls. These codes can be easily changed just in case some neighbor is using the same code on his garage door. You used to be able to get a universal garage door remote control unit from a place like SEARS.
My 325 ci has three buttons on the left side of the rear view mirror that can be programmed (learn) to immitate the signal from a garage door opener and other low power RF devices.
