My wife has inherited a 2005 Venture. It has electric locks, but didn't have a remote. I don't know if my Father-In-Law (he was 90) lost the remote or if it never had one. Is there any way I can determine if the van came with the factory Remote Keyless Entry system installed? If it did, I can get a replacement remote, otherwise I will have to pay several times as much to get a third party system installed.

Thank you,

Bobbo
