If the keys you got are basic Suzuki keys, then NO, you don't have keyless entry. The Forenza/Reno remote is built into the key itself, so you'd know right away if you had it or not.
certain trim packages came with Keyless and some didn't.
Suzuki doesn't filter their catalog by VIN as other makes do so a VIN won't help. If not keyless you'll need the module.

Lock your car with the keyless entry.Push it twice.Then walk over to passenger side and un lock with key.Then put key in ignition and start the car..If that dont work lock the doors again with the keyless entry.Push lock twice and then push the unlock twice..that should start your car,Repost if you have no luck to consider different stratigies.
