doors won't open usjng the remote

My first guess would be that the small cell battery inside the remote might be dead and in need of replacement. If that's the case, it's normally an easy to find cell battery like a CR 2032 and most local pharmacies, grocery stores, and of course, auto stores sell them. If you know it's NOT the battery, you could have a problem with a computer chip or something inside it....BUT definitely, check the battery 1st!

2005 Town and Country remote does not unlock door or lock panic button doesn't work new battery in remote if I use the remote starter and start the car the remote works
