To program your keyless-entry remote, press and hold the "LOCK" and "UNLOCK" buttons on the key fob simultaneously until the locks cycle once more. This could take up to 30 seconds, so be patient
This is a little vague. Do this on the old, working remote or on the new one that we're trying to program? Are you claiming this is the only step or is this a replacement step in the process listed in the owner's manual?
