If it comes with a keyless entry remote it does, if it did not come with a remote then it does not. Also if you do not have power locks you do not have keyless. If you do have power locks but no remotes it can easily be added.
did you buy the car used? if so, and you have not key fobs. do this
insert key and turn to ON 4 times and then pull the key out. if you get an extended tone, this means that you have keyless entry. after this tone, you have 30 seconds to program any fobs. this is done by pressing the lock and unlock buttons on the fob at the same time.[thumb]
Take a look behind the glove compartment where the pcm is mounted. I have an 03 and the power lock/keyless entry module is mounted on top of the pcm. It's probably in the same place on your year if you have it. I didn't know about the tone trick so give that a try as well.
