A keyless ignition system — also called a smart key — is a method of electronic access and authorization of an entry and ignition system that’s available as an option or standard in several cars.

The first smart key was developed by Siemens in 1995, and introduced by Mercedes-Benz under the name “Key-less Go” in 1998 on the W220 S-Class following its design patent filed by Daimler-Benz on May 17, 1997.

Although keyless ignition systems have been around for 20 years and are available on autos of all makes and models, and at all price points, there are some concerns about safety and security.
