Lost Your Only Car Key Fob? Here's How Replacement Works

Losing the only key fob for a car feels like a big deal, and it can be expensive at a dealer. Here’s what actually happens.

Why fobs cost more than old keys

Most cars since the late 1990s use a transponder chip the car must recognize before it starts. A new fob has to be cut (if it has a blade) and programmed to your vehicle.

Your options

• Dealer: works, but often means towing the car in and waiting for parts.
• Mobile locksmith: many can cut and program keys on site, including transponder keys and key fob programming.

Have this ready

• Proof you own the car (registration or title) and a photo ID.
• The VIN, which is visible through the windshield.

Then get a spare made right away. A second key costs far less than an all-keys-lost job.
