Smart & Proximity Key Replacement

Push-to-start smart keys and proximity keys replaced and programmed in Brooklyn. What makes smart keys different and pricier.

Smart keys — also called proximity keys or intelligent keys — let you unlock the doors and start the engine with the key still in your pocket. They talk to the car continuously on a low-power radio channel, and the car decides from distance whether to wake up.

Why they cost more

A smart key carries more electronics, and pairing it usually involves a security handshake that takes longer than a basic transponder. Replacement starts at $220 for most models. If you are unsure whether your car uses a smart key or a plain remote, read smart key vs remote fob first.

Common failure

Nine out of ten "broken" smart keys are just dead batteries — the car suddenly does not see the key even though the buttons look fine. Try a battery service before paying for a full replacement.
