Can you imagine in case you lose your Lexus IS300 electronic keys, how much it'll cost you for replacement? Don't get shocked if I say $335. Yes, it's true, as per Roland Jones. You just can't go to the hardware store next door and get it fixed.
The more electronic chips and computerized anti-theft ignition systems we're fixing in our cars, the more we're exposing ourselves to the risk of locking us out of our vehicles. A car's computer system cannot be re-programmed with a snap of a finger, it may take couple of days to fix it and scoop out the right key. Meanwhile the customer is forced to get a rental car and end up adding more to the key replacement bill.
Automakers too are reluctant to disclose the codes in the wake of the burgeoning key replacement services and hence they explicate it in their own electronic way that disclosing codes will ultimately leave their anti-theft systems redundant. So, next time if you hold an electronic key make sure not to flush it accidentally down the toilet or be ready to make a big dent on your wallet.
