I was wondering how I would install a keyless entry on a 04 civic vp?

 

The module and some key fobs is the materials you would need. They discontinued it years ago, so you're going to have to do some searching for a used or never-opened setup available somewhere second-hand.

 

Does your civic with center locking system because I heard that those specific cars do not have center locking system and therefore the system that can be install oem Honda is the security system which utilized the keyless unit to arm and disarm the security system. If you do have the center locking system in your civic than like Matt (toyomatt84) said you have to look around I still have the brand new fobs and the keyless unit but I don't have the wiring which is important. Hope this help.
