The rise of computerized vehicle immobilizers has made keeping watch on one’s keys even more imperative than it used to be:
Noticed last night at bedtime it was missing (I was absolutely sure I knew where it was, in the usual place, which means I was distracted when I put it away yesterday), searched for a couple of hours without results. Slept, woke, and searched for six hours more. That got me to noon and I gave up, called the dealer, called a tow service (because it’s 2019 and your car has be told the new keys are friendly keys), and spent the afternoon getting my key replaced and another added, at a price that seems disproportionately high —
But it’s 2019 and my car’s computer only trusts the dealer’s officially authorized computer.
I remember when a car key ran four bucks. Now it’s more like four hundred.
The last time I bought a battery for Gwendolyn, the shop left the car parked fairly close to the street, so I could make a speedy exit. I picked up the remote, mashed the button, and — nothing. After the fourth try, I gave up, unlocked the door with the actual key, and drove home. Some time in that nine-tenths of a mile, the computer, having seen the key for itself, concluded that I must be the correct driver, and reset the remote, which worked just fine thereafter.
