I have read that at times when this happens, the remote needs to be
're-synced' to the car. Try holding the LOCK and UNLOCK buttons together for
several seconds until the horn chirps. Then see if the remote works.
That's actually fairly similar to a question that's been building in my
I have two fobs from a '98 Regal that got totaled. I replaced it with an
'03 Grand Am. The Grand Am only came with one fob and I'm hoping I can
reprogram the Grand Am to work with the fobs from the Regal... or reprogram
the fobs to work with the Grand Am - which ever way it really works. I'm
interested in further discussion on this matter.
No, sorry. The fob's are different for certain cars and years. For example,
while your '98 Regal Fob would usually work for a '97 or '99 Regal, it would
not work with a Grand Am at all, let alone an '03.
The key in using Fob's is to look at the numbers on the back. You will see
'FCC ID' and other numbers. If the numbers on the old remote match the ones
on the remote you found, then you will be fine. If not, it won't work. As
for programming, that is not what you did. You 're-synced' your remote to
your car. That means, that the remote was already programmed, but the car
'forgot' about it in a way. Its like when your cordless telephone stop's
working, so you put it on the charger for several seconds, and it works
To program a new Fob to your '03 Grand Am, you would need an exact replica
of the one you have for it, and programming instructions.
By the way, as to your last question, you program the *car* to work with the
remote, but like I said, it has to be the exact same numbers as the one you
Hope this helped.
