Here is what the page “BMW i3 Key Replacement Cost: Modern Car Keys Cost 20 Times More Than 1990s Keys” contains. Replacing a lost or missing key for a modern car like a 2014 BMW i3 can cost as much as buying a used car, according to a recent report by The Autopian. The author, who recently purchased a used i3 with only one key, discovered that a replacement key fob from BMW can run upwards of $500 to $700, and sometimes over $1,000 when programming and labor are included. In contrast, a typical 1990s car key—a simple metal blade with no electronics—costs just $5 to $20 to duplicate at a hardware store.
That's a 20-fold to 50-fold increase for modern keys, driven by integrated transponder chips, remote locking, and push-button start systems. The high cost matters because many used cars are sold with only one key, and buyers often don't budget for a spare. The full version stays on the original page, which this listing opens directly.
