Once you get your new Smart Cards activated, there is no way to get old smart cards to work agian.
In some very rare cases, you can use the old card and it will give you programming but you may loose it in few hrs or days, possibly before your new card arrives.
The only way to tell if your old card will work is to try it. If it is going to work, it will work right away without any hits. But if you get error 349 then you're out of luck.
