I have seen in my Lexus manual that the homelink can be used to open not only garage doors but remote home door locks as well. I have been searching and it appears that someone used to make them but quit and I have not been able to find one to buy.

Do any of you know who might have one of these or know if they work at all?

contact homelink

I had went to their website :Homelink Home Security Page, but it just says there were two companies that made them but are no longer being made.

I just wandered if anyone knew of a source that might have them?

I have not had any success either in finding products compatible with HomeLink. In our last house we had wall mounted light switches with built-in receivers that allowed us to turn on exterior and interior lights with a garage door opener. I wish I could find something similar for our current house.
