Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

First, look around the battery area and make sure you didn't forget to connect a wire (usually a red or black/ground); sometimes they manage to fall down near the frame or block and are not hard to miss when reconnecting wires; then, if all wires are connected, contact a representative at a local auto parts dealer and ask if it would be safe to unplug the computer and reconnect it. This should be okay, as long as the engine is off. Then, start the van and see if the fob works (if inside of van is accessible).

Please let me know if you need further assistance,

SOURCE: battery in key fob went

hi you can do this but you will have to have a key that does not have a remote/fob on it ( basically just go get one cut cheaply ) then to reprogram keys/key fob's first using the key without fob, turn ignition on ( do not turn over, just to position 2) then lock drivers door with other key ( do not use fob, just the key itself with fob now complete the following within 30 seconds within 5 seconds( of locking the car) press the unlock button on the first key once ( this programs that key as key memory1) the indicators should flash once to indicate signal received wait 5 seconds then press unlock on key fob vehicle should then unlock meaning key fob has been programmed and programming ended open door turn ignition off , and that's it, it should work if you have more than 1 key with fob, do the same as above but instead of pressing unlock once, you do it twice, if third key 3 x if fourth key 4 x etc etc,
