This is one benefit of being a mechanic. I can score a new key fob for about 40bucks. This is for a G.M. car, can't help with Toyotas. My truck has 300,000 miles on it, btw, and still cruises the freeway fine. A car will last as long as you are willing to fix it. I know, it's not cost effective for most people to keep dumping money into an old bucket, and I actually am considering a new car myself.
