garage/car remote

I lost one of my remotes for the garage door opener. Was wondering if anyone has experience with keychain universal remotes for the garage door opener. Ultimately I’d like to have one remote for both the car and the garage opener. I have three cars 96 Volvo 850 – factory remote, 95 Toyota Camry – Pursuit security remote, 05 Camry – factory remote (not a security system)
Would appreciate any ideas you can give me!

I don't think this is possible, unless you have a HomeLink-compatible alarm fob.

The only way would be to get 3 keyless entries or remote starters from Directed Electronics then get the home automation kit. With that, you can open and close garage doors and even turn on and off lights.

Thanks a lot for your replies! I will keep looking and let you know if I find something worth wile...
One remote looks promising
but don't know it really works as it promises

Yeah I dunno. You have a very large range of cars so it will be difficult to get one remote to interface into existing OEM and aftermarket systems
