Roberta X. bought a used Lexus and:
That was mildly interesting, so I set it to one side. I bought my present Lexus RX-mobile* from their used-car lot, with exactly one key for it; maybe they found the others?
You know, when I traded my old pickup truck for an SUV last year, we ended up with an older Lexus with a then-luxe interior including a cassette deck. It came with two keys; when we got into the car, I gave the key with the fob (lock/unlock/panic buttons) to my beautiful wife, put the key without the buttons on my keyring, put the key in the ignition, turned, and…
I could not start the vehicle, and after a few tries, I started to get angry. I thought about the lemon law, storming in and demanding my old truck back and whatnot, but she (my beautiful wife, not Roberta X.) was really sold on the vehicle. The salesman came out with obviously artificial regret, but this particular vehicle only came with one key that could start the car–one with the integrated chip–and one that could unlock the doors, maybe. We could order another key with an integrated chip for a couple hundred dollars.
Which we did, because she was very taken with the vehicle, and I spoil her.
But I’ve added another thing to check when buying a used vehicle.
Between this and buying houses, I’ll know all the gotchas to look for after I’ve bought my last car or house. Although it’s probable that I’m too optimistic in thinking I can ever know all the tricks.
