lost viper remote and keys

No what it's reffering there to is remote control over a function that may have been programmed for a specific button that was not intended for the particular purpose, so if you were to erase all transmitters and re-program new ones the remote would return to default setting and you may have to use a different combination of buttons instead of just one to access the same feture that you used with one button before!

Know i didn't explain it well, but no worries just go right ahead and erase and re-program!  

I received the replacement Remote Transmitter for the alarm today. However there's a discrepency, on the Viper 5900 Alarm Manual it states the number of times i need to press the program switch to delete all trasmitters is 14. However on the replacement remote it says I need to press the program 11 times to delete all transmitters. Because my remote was lost i want to make sure im erasing the transmitters correctly before programming the new remote.

Does anyone know the correct number of times i need to press the program 14 or 11?

These are the instructions listed in the Viper 5900 Installation Manual:

Yes dear pressin the valet switch 14 times will delete all transmitters, although i've never done it before (i always use a bitwriter, makes things alot easier), i'm sure it will, for auto learn, after you've erased the transmitters, turn on the igniion and press the valet switch twice and hold on the second press, when you hear a single chirp from the siren the depress the lock button on the remote, after this you should hear a long chirp. That indicates succes!
