Editing Lock and key (section)

===With electronic keys===
An [[electronic lock]] works by means of an electric current and is usually connected to an [[access control]] system. In addition to the pin and tumbler used in standard locks, electronic locks connect the [[dead bolt|bolt]] or [[cylinder lock|cylinder]] to a motor within the door using a part called an actuator. Types of electronic locks include the following:

A [[keycard lock]] operates with a flat card of similar dimensions as a [[credit card]]. In order to open the door, one needs to successfully match the signature within the ''keycard''.

The lock in a typical [[remote keyless system]] operates with a [[smart key]] radio transmitter. The lock typically accepts a particular valid code only once, and the smart key transmits a different [[rolling code]] every time the button is pressed.
Generally the car door can be opened with either a valid code by radio transmission, or with a (non-electronic) pin tumbler key.
The ignition switch may require a [[transponder car key]] to both open a pin tumbler lock and also transmit a valid code by radio transmission.

A smart lock is an electromechanics lock that gets instructions to lock and unlock the door from an authorized device using a [[Key (cryptography)|cryptographic key]] and wireless protocol. Smart locks have begun to be used more commonly in residential areas, often controlled with [[smartphones]].<ref>{{cite web|title=Ditch the keys: it's time to get a smart lock|url=http://www.popularmechanics.com/home/improvement/security/ditch-the-keys-its-time-to-get-a-smart-lock-16200140|website=Popular Mechanics|access-date=15 June 2016|date=26 November 2013|url-status=live|archive-url=https://web.archive.org/web/20141216010141/http://www.popularmechanics.com/home/improvement/security/ditch-the-keys-its-time-to-get-a-smart-lock-16200140|archive-date=16 December 2014}}</ref><ref>{{cite web|title=Kisi And KeyMe, two smart phone apps, might make house keys obsolete|url=http://www.huffingtonpost.com/2013/11/26/house-keys-extinct_n_4339682.html|work=[[The Huffington Post]]|date=26 November 2013 |access-date=9 June 2015|url-status=live|archive-url=https://web.archive.org/web/20150311201754/http://www.huffingtonpost.com/2013/11/26/house-keys-extinct_n_4339682.html|archive-date=11 March 2015}}</ref> Smart locks are used in [[coworking]] spaces and offices to enable keyless office entry.<ref>{{cite news|last1=Kurutz|first1=Steven|title=Losing The Key|url=https://www.nytimes.com/2014/06/12/garden/losing-the-key.html?_r=0|work=The New York Times|date=11 June 2014 |access-date=9 June 2015|url-status=live|archive-url=https://web.archive.org/web/20160103232758/http://www.nytimes.com/2014/06/12/garden/losing-the-key.html?_r=0|archive-date=3 January 2016}}</ref>  In addition, electronic locks cannot be picked with conventional tools.
