I have a 2007 Isuzu Ascender and I have those 3 buttons above the rearview mirror. I was told it is for your security alarm system and garage door opener. How do I set it?

what are you doing?
what is the job here?
is something broken?
are you making modifications
whaT?

is this a, mirror dim question? (tilt dim feature)

You only have a short time to get into program mode and push the remote button. there Should be a button on the garage opener as well, try having someone push the button on the garage door opener while you push the in car button. If that doesn't work your opener may not be compatible.

Take your remote and hold it up towards your rear view mirror or your visor whitchever is the one with 3 buttons of your homelink , also make shure that your opener has a program button which come in different colors depending on the year of the machine, if you have a program button on your powerhead of your garage door opener then you can mostlikely program your car to it! The button on garage door opener comes in different colors such as yellow,green ,orange, black, grey and black ! make shure your opener has one of these buttons! Now take your remote and point it within a few inches of your visor/rearview mirror and hold the button down that oppens that door....now press the first button on your car mirror/visor until the door opens up , it take sometimes a few trys but remember to leave your car running while doing this and have it outside the front of your garage door while doing this!

1. Press and hold button on car's rearview mirror
2. Press and hold button on garage door opener's remote control.
3. Light on Rearview mirror will flash rapidly.
4. Release both buttons.
5. Locate learning button on garage door opener (generally this can be found by tracing the antennae to where it is attached to the unit.)
6. Press and release "Learning button"
7. Press and release rearview mirror button repeatedly until garage door opens/closes but it should work the first or second time.

Worked on Genie Intellicode and Hyundai Tuscon

Go to the auto parts store. They sell a special kit to reattach your mirror. It is simple to do. You MUST follow the package instructions.

Thanks for your interest in FixYa.com

Although the fault may be in the mirror itself (like a switch), wiring and connector is above the headliner, and that is what you need to check.

sounds like a bad lock mech open door up and check acuator

There was a minor change for mine to work.. see below..

- you must park your Prius close to the gate opener, leaving it running (obviously not in the way of the gate closing)
- Hold the button the the mirror and then push your garage door remote button and hold until the light on the mirror starts to flasyh fast. THIS programs the button on the mirror, but not the garage opener - yet (this was key for me)
- locate the "learning button" on the opener itself
- press the "learning button" on your gate opener and then get back into the Prius within 30 seconds (more time than it sounds) and press the SAME Homelink button you just programmed above. I don't recall how long I held the pre-programmed button, but the light will flash as I recall.
- Then, when working the garage door, you may need to hold the mirror button for a good second for it to work - but I had tried for months to get mine to work, and finally after reading many posts, the above sequence worked on my 2008 Prius with my Lift Master, Security + rolling codes garage opener.

Just - program the button on the mirror with your remote FIRST.. the garage opener will not work.. then use the Learn button on the garage opener and the SAME BUTTON you just programmed.. and it worked great for me. Not programming the mirror button first will not work. Using only the Learn button will not work. You must program the mirror first with the remote, then use the learn button and the SAME button on the mirror. Hope this helps.
