Complicated vs. Complex - Part Two

Back again for another short journey into the minds of automobile engineers. My son recently returned for his Junior year of undergraduate study. This is the first time he has brought his car along. We thought he should keep the spare key and fob for the remote entry in his apartment. But just in case something should happen, I wanted a key to have back home. So we stopped by the local Ford dealer. A friendly person in the parts depaqrtment asked if we had the car with us. It is a 2002 Ford Escape. No, it was back in the college parking lot. We were told that these cars used a "smart" key that had to be programmed to the exact vehicle. It wasn't clear if this was part of a theft-protection scheme, or served some other purpose. But it was clear that the car knew if its properly programmed key was in the lock or not. Moreover, getting a new key cut and programmed would cost $106! We looked at the key closely and sure enough, there was a small removeable part that presumably gave access to the programmable memory chip inside the key.

We decided that it was not worth the time or money to have a third key made.

Cost of a key to get into my home - a few bucks at the hardware store.

Cost of an allegedly "smart" key for the Ford - $106.

The value of simplicity in design and manufacturing - priceless.
