I recently had my Fob stolen so had the system remove that fob from the car.  To stop the alarm why didnt you just hit the unlock button on the dash above the radio?
I purchased one of those fobs from ebay and when I tried to have it coded to the car it would not work - so be wary.  I had the local mobile car locksmith the reprogram it so I just bought a new fob off him.
Total cost was $150 to come and reprogram the old fob - wasted $$$.
The new fob was $100 (with a rechargaeble battery) and $150 to program but he waved the original $150 so all up new fob, programmed to the car was $250.  
Pretty good value I thought.
So use your mobile car locksmith.
