'''''Through the Keyhole''''' is a British [[comedy]] [[panel game]] show created by the TV producer Kevin Sim and originally presented by [[David Frost|Sir David Frost]] in the studio and [[Loyd Grossman]] on location. The location presenter explores celebrities' houses and a panel of other celebrities in the studio try to guess who the famous homeowner is.

The show was originally produced by [[ITV Yorkshire|Yorkshire Television]] and was broadcast on [[ITV (TV network)|ITV]] from 3 April 1987 to 1 May 1995, then on [[Sky One]] from 22 February to 23 December 1996 before moving to [[BBC One]] from 5 May 1998 to 2004 and its sister channel [[BBC Two]] from 26 February 2006 to 4 June 2008.

In 2013, the show was revived for ITV with [[Leigh Francis]] as the host.<ref>{{cite web|url=http://www.radiotimes.com/news/2013-05-16/keith-lemon-to-revive-through-the-keyhole-on-itv|title=Keith Lemon to revive Through the Keyhole on ITV|work=Radio Times|date=16 May 2013}}</ref> In February 2020, it was reported that the programme had been cancelled after six series.<ref>{{cite news|url=https://metro.co.uk/2020/02/16/keith-lemons-keyhole-axed-six-series-itv-12248790/|title=Keith Lemon's Through The Keyhole 'axed' after six series on ITV|date=16 February 2020|work=Metro|first=Cydney|last=Yeates}}</ref>

==History==
===Original series===
''Through the Keyhole'' originally started as a segment on [[TV-am]], first being broadcast on its launch day on 1 February 1983.<ref>{{cite web|url=http://www.express.co.uk/entertainment/tv-radio/370964/Rise-and-shine-The-joys-of-breakfast-television|title=Rise and shine: The joys of breakfast television|last=Hassell|first=Katherine|date=15 January 2013|work=[[Daily Express]]|publisher=[[Northern & Shell]]|access-date=17 February 2013}}</ref> The idea was created by Kevin Sim as a chance to look around some of the most influential homes with Grossman at the helm as the tour presenter. Grossman was mistakenly given the job after someone had confused him with another journalist.<ref>{{cite news|url=https://www.independent.co.uk/arts-entertainment/television--long-runners-no-35-through-the-keyhole-1421961.html |archive-url=https://ghostarchive.org/archive/20220507/https://www.independent.co.uk/arts-entertainment/television--long-runners-no-35-through-the-keyhole-1421961.html |archive-date=7 May 2022 |url-access=subscription |url-status=live|title=Long Runners: No 35: Through the Keyhole|last=Thompson|first=Ben|date=12 June 1994|work=[[The Independent]]|access-date=17 February 2013}}{{cbignore}}</ref> It became a regular feature of TV-am throughout 1983<ref>{{cite news|url=https://www.nytimes.com/1983/12/01/arts/morning-tv-is-the-talk-of-britain.html|title=Morning TV is the Talk of Britain|last=Bedell|first=Sally|date=12 January 1983|work=[[The New York Times]]|access-date=17 February 2013}}</ref> until May 1985. 

In Spring 1986<ref>Brief Note: Scunthorpe Evening Telegraph, P2: Monday 05 May 1986</ref><ref>Role reversal, Newspaper: Aberdeen Evening Express P15, Saturday 10 May 1986</ref> Frost transferred the concept to [[ITV Yorkshire|Yorkshire Television]] who picked up format, to produce a full half-hour programme for [[ITV (TV network)|ITV]], where a celebrity panel tries to guess whose house is being looked at From 1987. It ran in primetime on Friday nights for eight years on ITV and was rarely out of the top ten entertainment programmes on TV. The executive producers were Kevin Sim and Chantal Rickards. From 1996, it was produced by Frost's own production company, Paradine Productions, at Yorkshire Television. That same year, the show also moved to [[Sky One]] for one series. It then moved to [[BBC One]] ''Daytime'' in 1998 until 2004. The final three series aired on [[BBC Two]] from 2006 to 2008, when it was cancelled by the BBC. However, a special aired in March 2011 for ''[[Red Nose Day 2011]]'' as part of marathon panel show ''24 Hour Panel People''.{{cn|date=December 2024}}

===Revival===
[[File:Through the Keyhole set.jpg|thumb|left|Through the Keyhole set at [[BBC Elstree Centre]] in 2018.]]
In 2013, the programme returned on its original broadcast channel ITV with [[Leigh Francis]] (in character as Keith Lemon) taking up the dual roles of studio presenter and house detective. The new series was filmed at [[Pinewood Studios]] until 2018, with series 6 filmed at the [[BBC Elstree Centre]]'s Studio D in the latter half of the year.<ref>{{cite web|url=http://www.virginmedia.com/tvradio/news/story/2013/01/24/keith-lemon-confirms-through/|title=Keith Lemon confirms Through the Keyhole revamp|date=24 January 2013|publisher=[[Virgin Media]]|access-date=17 February 2013}}</ref><ref>{{cite web|url=http://www.comedy.co.uk/news/story/000001014/keith_lemon_through_the_keyhole/|title=Keith Lemon to present Through The Keyhole revival|date=13 January 2013|work=The British Comedy Guide|access-date=17 February 2013}}</ref> [[Dave Berry (presenter)|Dave Berry]] was a regular panellist. The first episode of the revived series aired on the same day that former host Sir [[David Frost]] died, although the news did not break until the following morning.<ref>{{cite web|url=http://www.digitalspy.co.uk/showbiz/news/a511567/sir-david-frost-dies-aged-74.html |title=Sir David Frost dies, aged 74 |date=1 September 2013 |work=[[Digital Spy]] |access-date=1 September 2013}}</ref>

Before his death in August 2013, Frost gave his backing to ITV's remake, saying: "I am delighted that the Keyhole format is now entering its fourth decade on TV. I know the pilot show went down very well with the studio audience and I wish Keith and his team the very best of luck for the series."<ref>{{cite web|url=http://www.digitalspy.co.uk/tv/news/a482027/keith-lemon-through-the-keyhole-gets-sir-david-frost-backing.html |title=Keith Lemon 'Through the Keyhole' gets Sir David Frost backing |last=Fletcher |first=Alex |date=16 May 2013 |work=Digital Spy |access-date=1 September 2013}}</ref>

==Format==
At the start of each episode, Frost introduces a panel of three celebrities with the catchphrase "And ''what'' a panel they are&nbsp;..." and some gently humorous or mocking descriptions. He then hands over to the location presenter who gives the panellists a guided tour of a property, noting particular items, though there is typically a large amount of [[wikt:misdirection|misdirection]] involved as the items pointed out by the presenter are not necessarily the most pertinent clues to the person's identity. Items not specifically mentioned may provide much more useful clues. Once completed, Frost reveals the identity of the guest to the audience and the panel are given turns at guessing their identity. The audience participate with varying degrees of applause according to the accuracy of the panellists' guesswork.

The panellists are either successful at identifying the guest or Frost reveals their identity, after which they are interviewed and given a key-shaped trophy as a memento. Starting during Loyd Grossman's reign as location presenter, the geographic spread was extended with one of the properties on each episode being located in the US and one in Europe. When [[Stefanie Powers]] joined in 2007, she was based in the US and conducted the US property tours, whilst in the UK [[Lisa Snowdon]] conducted the European part.
