Warning Light On problems of the 1999 Chevrolet 1500

I had the ignition sleeve required in recall done. Never had problems with key before that. Since then, have trouble starting car; the garage replaced battery (was 6 yrs. Old) because they could find nothing else wrong with the car. Still I have difficulty starting the car. . . . . . . . . . Yesterday it took 3 tries. I moved in the interim of having this done. . . . So going back to simon Chevrolet in woonsocket,ri is out of the question. I called salvatore Chevrolet in gardner, MA. And they told me there would be a $200. Charge to find out what the problem was. Never had problems before and this should not be a charged for issue. Any suggestions? also, this morning the diamond shaped button for the warning lights broke off and fell into dash. . . . . . The car is sound and I keep it well kept up. These are just frustrating issues. Please advise. Thank you for the time and effort put into this matter. Sincerely. . . . Jacqueline cushman.
