Battery disconnected and boot accidentally closed BMW 1 series 2010 2 door How do I open?

**** >>> This setup I performed with my new 2010 BMW 528XI Garage Door Homelink and Chamberlain Garage Door Opener <<< ****

Chamberlain:
01. Power off or unplug the garage door opener motor power supply (which is mounted on ceiling of the garage) ;;;

02. keep the garage door opener transmitter in your hand (do not press any button at this time) ;;;

03. In your 2010 BMW 528XI Homelink button (which resides under rear view mirror) press the 1st and 3rd homelink button together for about 30-40 seconds (i.e., until the yellow light blinks fast) and when the yellow light next to the homelink button blinks fast release from pressing the (homelink) buttons ;;;

04. now hold the garage door opener transmitter closer (means within 2-4 inches) to the homelink button (either 1st or 2nd or 3rd) whichever you are planning to program to open the garage door ;;;

05. now press the garage door opener transmitter button and chosen homelink button (either 1st or 2nd or 3rd whatever you need) together ;;;

06. the yellow light (next to homelink button) initially may blink slowly but after few seconds (may be 10-20 seconds) will blink fast; once it started blinking fast release from pressing both garage door opener transmitter and homelink button ;;;

07. Now plug or power on the main garage door opener motor (which is mounted on garage ceiling) ;;;

08. On the main garage door opener motor (which is mounted on garage ceiling) press the "LEARN" button (once you press it may have yellow/orange color light; make sure the light is on) ; then within 30 seconds do the next steps #9, #10, #11 very carefully ;;;

09. go to your car and press the homelink button you programmed and hold it for 4 seconds and then release it --> 1st iteration ;;;

10. again hold the same homelink button you programmed and hold it for 4 seconds and then release it --> 2nd iteration ;;;

11. again hold the same homelink button you programmed and hold it for 4 seconds and then release it --> 3rd iteration ** important note; generally three iterations are not necessary; and steps #9, #10, #11 must be performed within 30 seconds ** ;;;

12. during one of the iteration you will hear "CLICK" sound one-time from Garage door motor (which is mounted on ceiling) and if you have light attached with it; it will blink once (** if you hear the CLICK sound and/or light blinks once**) then the particular homelink button is programmed ;;;

13. now press the programmed homelink button; the garage door will open or close (but always it will take 3 or 4 blinks in yellow light or 2-3 seconds before the garage door opens or closes and which is normal) ;;;

** Thats it, your 2010 BMW 528XI Garage Door Opener Homelink setup is complete ** ;;;

You can program rest of the homelink button the same way but following from the steps between #4 and #13 ;;;

Hope this steps will help you to program chamberlain Garage door opener in 2010 BMW 528XI Homelink. ;;;


** possibly the above same steps may work with other BMW 5-series cars homelink too (but I'm not sure) **
