My 2001 Ram has power door locks which work from the buttons next to the electric window switches, but when I use the key in the outside only one door opens.
I have no remote for keyless entry, should I have one ? How can I find out ?

 

As far as using the key, I geuss you just have to hit the switch to unlock the passenger side. Sometimes you can turn the key to the unlock position twice and it unlockes the rest of the doors. I whent and tried that, and it doesn't work. As for the keyless entry, there is a good possibility that you have it. A few years ago my parents bought an Eddie Bower expedition. The dealership didn't have the key fob, so they told my parents that it did not come equiped w/ keyless entry. I thought it was strange that the top of the line package wouldn't have that. I talked my dad into getting on ebay and bidding on some remotes. He got a pair with programming instuctions for really cheap.(Under $30.00 I think.) Come to find out their truck had keyless entry. Someone had lost the original remotes. Took him about ten minutes to program and that was it. If you can find the remote cheap, it wouldn't hurt to try that. I have actully seen remotes for an 01 ram on ebay. Something to check out!

 

Sweet, I may try and get a remote for it.
