Three times last night, and once this morning, my 2000 Blazers remote starter, started the truck. The keys were on the table across from me. No one touched the remote. What gives?
Any explanations?

 

Did it happen at regular intervals? Some remote starters have an automatic mode where it will start the vehicle every 2 hours or so, run for about 10 minutes, and shut itself off. The general idea behind this mode is for areas that experience severe cold but electricity is not available to plug in a block heater. It's possible that you accidentally placed it into this mode.

If it's just happening at random and close together the first thing I'd suspect would be the key fob malfunctioning. A few other things to consider: Has the key fob gotten wet recently? Or the batteries replaced, or needing replacement? Was the remote starter installed by a reputable shop, or someone with proper knowledge to do it? It is possible that it's the remote starter itself malfunctioning, but much less likely.

 

Don't forget to check the second remote if you have one. Stashed away, maybe in a crowded drawer or in a couch cushion??

 

Take the batteries out of the remote and see if it happens again. That should tell you if its the auto start program
