2001 Stratus Remote Entry

I have a 2001 Dodge Stratus, which came with two remotes for keyless
entry, but stupidly enough they aren't programmed to work with the car.
I was told I'd have to go to the dealer to have them programmed but
that just means more money for them. Can anybody tell me if it is
possible to get around this? I know some cars with remote entry can be
synchronized with the receivers but I don't know if this is the same
for Dodges.

Any help is appreciated!
