I lost the keys, how do i get new ones or how do i unlock my car?

What year????
lost your spare, car came new with 2 keys,
never not have 2 keys, or pay the piper..
no year car stated, so that means nobody can wax accurate.
just made 3 key for my , new jeep yesterday. (proactive)
2 pods and 1 full,
my 04 (sold) GV, only one key can be programmed at a time.
but has no IMMO on car, only the door locks are dead on my spare.
the operators guide (lost that?) tells you how to get the fob programmed all by your self.
the key , any lock smith in earth can cut you a new one.
but house calls or road trips are more money. to cure that.

GV are sold all over the world. 1999 to now.
we cant guess that either and some have Immobilizers..
