Key Question
 

How do I find out which remote keyless entry is right for my van. I just bought a 06 Grand Caravan Special Edition. It only came with one key and no keyless entry keys. It has power everything doors and back hatch.

Your keyless entry should be part of your key. If its not. Then go to the dealer and find out if you have SKEEM module. and also have them ck the FCM or BCM for keyless entry funtions.
