Does my 98 have keyless entry

This may be a dumb question, but my wife bought a 98 altima and the seller didnt have a keyless entry remote. How can I check to see if it is equipt and I have to buy a new remote, or it isnt equipt and I have to install a kit?

i also bought a 98 altima se with no keyless entry remote. ive learned that ALL 98 altima SEs came with a keyless entry system. someone told me to just buy a remote anywhere but the dealership. the programming directions are found on several of these threads. go to ebay and you can buy a remote for about 12-20 bucks. im still waiting for my remote so ill tell you how it goes. wish me luck!
