Keyless Entry, Fleetwood

could anyone tell me how to see if my 93 Fleetwood is equipped with the keyless entry? i bought it used and it only came with one set of keys and no remote.

Check the RPO (Regular Production Order) codes. They are most likely on a white sticker in the trunk. On some cars, they are under the cover for the spare tire.

ive got this sticker, but no clue how to read it, looks like just a bunch of numbers. do you know which code is for keyless entry?
