Garage Door Remote! (HELP!)

[luka]

Hello my name is Luka.
I live in Germany and I would like to know if i could build my own garage door remote...
This is the garage door remote:
http://www.smolka-berlin.de/onlines..._F1024_1._1-channel,_27.015_MHz_21.001.30/986
I don't have the original remote anymore unfortunately.
It would cost like 80€ (100$) for a replacement. Which is a price I am not willing to pay.
I am quite good (and interested) in Electronics. But I'm new to the whole radio stuff.
Please bare with me.

So, is it possibe?

Thank you so much in advance.
-Luka

Since you don't have the original, and probably don't know the exact frequency or the format of the signal it sends, you are in a pretty poor place to try to build one.

I think its cheaper to get a whole new system but try ebay and look for a good deal.

Many garage door openers have the ability to control via an external switch, so your may have somewhere to attach one.
The door controllers I have seen usually have 2 screw terminals, and a momentary short activates the door (open, close or stop, depending on its current location).

You can buy small 433Mhz remote control units on eBay very cheaply, usually with 2 small keyfob remotes, that can give a momentary or toggled output depending on your requirement

I have found this is better than trying to source / repair the old remote units.
