With immobilizer/transponder key systems I have lost a least 90% of the theft recovery repairs that I used to see in the 1990’s.
With push-to-start/proximity systems I no longer replace ignition lock cylinders, I have seen many cars towed in because of binding lock cylinders.
20 years ago we sold aftermarket replacement transponder keys for $25. If the vehicle had keys with multiple buttons for power sliding doors for example a replacement key could cost $175.
Today’s proximity keys can cost $300. People spend more than that in restaurants each month but complain about the cost of replacement keys after dropping them into the lake.
