The fob takes a 12V battery. Can I just wire it straight to the battery (with a fuse) without any issues?

If I find the antenna connection on this thing, will attaching a wire to it and running it along the bike give me better range?

What's a good online source for parts? I need wire, a fuse holder, heat shrink tubing that I can cut to custom lengths (those 6" chunks that Radio Shack has aren't going to work), some ring terminals, etc.

Yes, but you gotta remember your battery is wired to your charging system that will probably produce about 14v. A $2 voltage regulator from Radio Shack might be a good idea.

Yes and no. If the wire isn't the right length it won't improve range and the power output limits the range too. Fucking with it probably wouldn't be practical...

Find a local electronics surplus store... shit is usually really cheap and the staff can help you with projects... Shipping on the electronics stuff usually kills the savings online.

Several good ideas...I just mounted a remote keypad outside of my garage which works for me.

Thanks for the link, reading it now...

I still need a decent source of electronic parts online if anyone has any suggestions. Out here in Nowhere, USA, Radio Shack is the only act in town. Their inventory is less than impressive.

mouser.com

get a catalog from them, the website trips my 50 relay.

mouser.com, I remember that place. Thanks!
