RS killing Alternator?

I installed a remote starter in my wifes Grandmas 99 Cavalier about a year and a half ago.  She just called my wife and told her she wanted me to pull it out because her mechanic said that the remote starter is killing the alternator.  I dont know any details about her conversation with the mechanic or why she even brought her car in, but I thought I would check here to see if anyone knows if this could be true that the RS is killing the alternator. 

Thanks

That is exactly what I thought, I mean the remote starter just does the same thing as the key does. 

But for posterity's sake, I have to ask if the RS could cause damage to the alternator if the RS was installed wrong, for example If an ignition wire was missed?  I know I  grabbed 2 Ignition wires and an accessory wire, which is all I can see is needed. 

I actually think that this is just a case of the mechanic thinking he knows all and just slipped a line in that those RS things are bad for your alternator and then my wifes grandma believed him and likely will be too stubborn to believe me when I tell her the mechanic was full of it.

Thanks guys.
