I have an 05 Silverado w/ the 5.3 liter. I have been having issues with the Pass Lock Security System. It has had a Marksman aftermarket remote starter installed in Detroit since 2005. Every once in a while it won't start and I have to wait ten minutes or so for the truck to start. It has been doing this for about 4 years but started to get worse lately. A mechanic told me these aftermarket remote starters can cause issues with this and quoted me $200 to remove it. I read that the Pass Lock can be bypassed or overrode fairly easily but electrical work is not my strong suit. My question is if this is done will I be able to keep the remote starter which is handy in Las Vegas? If I remove the remote starter and still have issues than it's a waste of money. Is overriding the Pass Lock going to disrupt or damage any other electrical units in my truck? Before I take it in to have it worked on I would like to have a better understanding of this so I won't get ripped off by a shop. It seems to be worse during the summer heat in Vegas. Any input would be appreciated.
